When a headache strikes, is your first move to look for pain relievers?

In fact, in the fight against tension headaches, migraines, and cluster headaches, the food we eat every day also plays a crucial role.

Which Foods Trigger Migraines?

A lot of times, headaches are what we “eat” ourselves into.

For migraine sufferers, certain foods are like invisible switches; eating them can trigger a painful attack within a few hours.

Common trigger foods:

Trigger Type	Foods	Possible Mechanism
Tyramine-rich	Aged cheese, fermented foods, pickled items	Tyramine promotes vasodilation, stimulating nerves
Nitrate-rich	Sausages, bacon, ham, and other processed meats	Nitrates cause dilation of blood vessels in the brain
Caffeine (Excess)	Large amounts of coffee, energy drinks	Excessive caffeine leads to rebound headaches
Alcohol	Red wine (contains histamine and tyramine), beer	Promotes vasodilation and dehydration
Artificial Additives	MSG, artificial sweeteners (aspartame)	May overstimulate nerves
Chocolate	Dark chocolate, products with high cocoa content	Contains tyramine and phenylethylamine

Not every migraine sufferer is sensitive to the same foods; everyone’s trigger list is different

Some people can eat cheese with no problems at all, while others start feeling a dull ache just from smelling MSG.

So, instead of memorizing a “do-not-eat list,” it is better to identify your own actual triggers by keeping a food diary.

What Can You Eat to Help Prevent Headaches?

Since there are trigger foods, are there “good foods” that can help prevent headaches?

Nutrient	Food Sources	How It Helps Headaches
Magnesium	Dark green vegetables, nuts, whole grains, bananas	Stabilizes nerve transmission and reduces vasospasm
Vitamin B2 (Riboflavin)	Milk, eggs, mushrooms, almonds	Improves brain energy metabolism, reducing migraine frequency
Omega-3 Fatty Acids	Salmon, mackerel, flaxseeds, walnuts	Anti-inflammatory, reducing neuropathic pain
Water	Plain water, sugar-free tea	Prevents dehydration headaches
Coenzyme Q10	Mackerel, broccoli, spinach	Improves mitochondrial function, stabilizing brain energy supply

Staying hydrated is the most easily overlooked preventive measure; mild dehydration is enough to trigger a headache.

Many people get busy and don’t drink water all day, and by the afternoon, a dull ache sets in. Developing the habit of drinking water regularly is the simplest and most effective way to prevent headaches.

Why Is Magnesium Particularly Important for Migraines?

Studies have found that many migraine sufferers have low magnesium levels in their bodies. Magnesium can:

Stabilize the excitability of nerve cells, preventing excessive discharge
Help muscles relax, reducing the occurrence of tension headaches
Reduce the cortical spreading depression phenomenon that triggers migraines

Getting enough magnesium (recommended 300-400 mg daily for adults) from your diet helps significantly reduce the frequency of migraine attacks.

Proper Medication Use for Three Types of Headaches

When dietary adjustments are not enough and a headache strikes, proper medical treatment is still necessary.

Headache Type	Acute Treatment Medication	When to Use
Tension Headache	`Acetaminophen` or `Ibuprofen` (OTC pain relievers)	Take as early as possible when the headache begins
Migraine	`Triptans`	The earlier you take it after pulsating pain appears, the better the effect
Cluster Headache	Oxygen therapy or fast-acting triptans (nasal spray/injection)	Use immediately during an attack; oral medication is usually too slow

The most important principle for pain relievers: take them early

Many people tolerate the pain until they can’t bear it anymore before taking medication, but pain relievers actually work best when taken within the first 30 minutes of a headache’s onset.

Once the pain has fully developed, the same dosage often fails to suppress it.

What Is Preventive Medication?

If migraines occur more than 4 times a month, or severely affect your quality of life, a physician may recommend using preventive medication.

Preventive medications must be taken regularly every day, not just when you feel pain
It usually takes 2-3 months of use to see significant results
The goal is to reduce the frequency and severity of attacks, not to eliminate headaches entirely

Taking Too Many Pain Relievers Can Actually Make It Worse?

“Medication Overuse Headache” is a new type of headache caused by using pain relievers too frequently, trapping you in a vicious cycle of more pain and more pills.

Diagnostic criteria:

Medication Type	Definition of Overuse
General Pain Relievers (Acetaminophen, Ibuprofen)	Used more than 15 days a month
Triptans	Used more than 10 days a month
Combination Pain Relievers (containing caffeine or opioids)	Used more than 10 days a month

Once caught in this cycle, the only solution is to gradually reduce medication under a doctor’s guidance.

Headaches may temporarily worsen in the early stages of withdrawal, but once you get through it, the frequency of headaches usually drops significantly.

Principles of Proper Medication Use

Do not wait until the pain is unbearable to take pain relievers, but also do not take them at the first sign of slight discomfort
Limit the use of pain relievers to no more than 2-3 days a week
If you find yourself taking them more and more frequently, you should discuss preventive treatment with a doctor as early as possible
Do not increase the dose on your own; if a standard dose is ineffective, it means you need to switch medications, not increase the dosage

Build Your Headache Defense Line Starting from Diet

We have more weapons against headaches than we think.

Dimension	Action Suggestions
Record Diet	Keep a food diary to identify your own trigger foods
Supplement Nutrition	Consume more foods rich in magnesium, vitamin B2, and Omega-3
Stay Hydrated	Drink water regularly every day; do not wait until you are thirsty
Correct Medication	Take pain relievers early, but avoid overuse
Seek Help	Discuss the possibility of preventive treatment with a doctor if headaches occur frequently

Don’t let headaches control your dining table. Starting from your next meal, build your defense line through what you eat.

How to Relieve Headaches? How to Handle Tension, Migraine, and Cluster Headaches? How to Prevent Recurring Migraines in Daily Life? Keeping a Headache Diary Really Works!

Sun, 24 May 2026 15:40:00 +0800

Do you feel like the entire world is spinning every time a headache strikes? Did taking pain relievers seem to have no effect?

In fact, different types of headaches require different coping methods. The three most common headaches— tension headaches , migraines , and cluster headaches —have completely different relief and prevention strategies. Using the wrong method not only fails but might also make things worse.

Three Headaches, Three Different Coping Strategies

We can adopt different coping strategies for different types of headaches:

Headache Type	Relief Method	Best Timing
Tension Headache	Apply hot compress to neck and shoulders to relax muscles, do stretching exercises, or drink a cup of warm water	When feeling a tight band around the head or neck stiffness
Migraine	Rest in a dark, quiet room, apply cold compress to forehead, or consume a moderate amount of caffeine	Unilateral throbbing pain, accompanied by nausea and light sensitivity
Cluster Headache	Seek medical help immediately; doctors may use pure oxygen therapy or prescribe fast-acting medications	Severe pain around one eye, accompanied by tearing

Relief methods for tension headaches and migraines are almost opposites

Tension headaches are suited for hot compresses to relax tight muscles, whereas migraines are suited for cold compresses to help blood vessels constrict. Getting them mixed up not only offers no help but might also worsen the pain.

First-Aid Tips During a Migraine Attack

When a migraine strikes, besides cold compresses and retreating to a dark room, here are a few tips:

A moderate amount of caffeine helps constrict blood vessels and can slightly ease the discomfort
Avoid bending over or lowering your head, as these postures will aggravate the throbbing sensation
If you have pain relievers on hand, take them right when the pain starts; waiting until it becomes unbearable usually results in poor efficacy

How to Prevent Migraines in Daily Life?

Beyond finding relief when the pain strikes, we can actually take the initiative in our daily lives to prevent headaches from occurring.

Migraines often have specific “triggers”, and everyone’s “landmines” are slightly different.

Common triggering factors include:

Trigger Type	Common Triggers
Lifestyle Habits	Insufficient sleep, staying up late, oversleeping, high stress
Environmental Factors	Weather changes, bright light stimulation, noisy environments
Dietary Factors	Alcohol, foods containing tyramine (cheese, chocolate), MSG
Hormones	Menstrual cycle fluctuations

If you want to avoid frequent migraine attacks, the most important step is to identify your exclusive triggers.

Keep a Headache Diary to Identify Your Personal Triggers

You might think: “How do I know what my triggers are?”

The answer is a headache diary.

Every time a headache strikes, record the following information:

Recorded Items	Examples
Onset Time	After waking up in the morning, during work in the afternoon
Pain Location & Sensation	Throbbing at the left temple, tight feeling across the entire head
Duration	2 hours, half a day
Sleep the Night Before	Slept for only 5 hours, slept for over 10 hours
Diet on the Day	Drank red wine, ate chocolate
Weather & Environment	Rainy day, muggy weather
Stress Level	Rushing a report, arguing with a colleague

After continuously recording for 2-3 months, you will gradually see patterns emerge

For example, you might find that you get a migraine every time the day after staying up late, or it strikes every time after eating cheese with red wine.

Once you know where your triggers are, you can consciously avoid them.

A Structured Routine is the Best Preventive Medicine

After identifying your triggers, the next step is to adjust your lifestyle habits.

Prevention Strategy	Concrete Actions
Regular Routine	Try to go to bed and wake up at the same time every day, including weekends
Moderate Exercise	Regular aerobic exercise (such as walking, swimming) can stabilize the nervous system
Adequate Hydration	Mild dehydration can also trigger headaches; drink enough water every day
Stress Management	Learn relaxation techniques to prevent stress from continuously building up

“Weekend migraines” are indeed real

Some people don’t experience pain when daily stress is high, but instead, a migraine strikes as soon as the weekend begins. This occurs because the body suddenly switches from a high-stress state to a relaxed state, and the nervous system fails to adapt in time.

Therefore, maintain a similar sleep schedule on weekends; do not suddenly sleep in until noon.

When to See a Doctor for Frequent Headaches?

If headaches have severely affected your quality of life, do not just tough it out on your own.

Frequently taking pain relievers might trigger “medication overuse headaches”, trapping you in a vicious cycle of more pain and more pills.

It is recommended to seek medical attention as soon as possible in the following situations:

Headaches occurring more than 15 days a month
Pain relievers become less effective, requiring increased doses to control the pain
The pattern of the headache suddenly changes (e.g., from a dull ache to a sharp, intense throbbing)
Severely impacts work, social life, and daily activities

A neurologist can evaluate whether you need preventive medications to fundamentally reduce the frequency of attacks, rather than just taking pain relievers every time it hurts.

Long-Term Strategies for Living with Headaches

Although headaches are annoying, as long as we understand their patterns, we can gradually regain control of our lives.

Strategy	Key Takeaway
Understand Your Headache Type	Clarify whether it is tension, migraine, or cluster to use the right method
Keep a Headache Diary	Continuously track to find your personal triggers; everyone’s triggers are slightly different
Adjust Lifestyle Habits	Regular routine, moderate exercise, and adequate hydration
Use Medications Correctly	Do not over-rely on pain relievers; seek preventive treatment when necessary

Don’t let headaches control your life; starting to understand them is the first step to reclaiming control.

Different 'Headache Locations' Mean Different 'Headache Types'? How to Know if It's 'Tension Headache', 'Migraine', or 'Cluster Headache'? Preliminarily Determine Headache Causes from 'Where It Hurts'!

Sun, 24 May 2026 13:10:00 +0800

Is your temple throbbing, the back of your head tight, or does your whole head feel like it’s wearing a tight headband? Have you noticed that the location of your headache seems to be different every time?

In fact, you can preliminarily determine which type of headache you have simply from “where it hurts.”

Different Locations, Different Headache Types

There are many types of headaches, but the locations where they strike often follow a pattern. By dividing headaches roughly into three areas, it will be much easier for you to identify yours.

Tightness in the Whole Head or Back of the Head: Tension Headache

This is the most common type of headache, experienced by about 70% of people.

It feels as if an invisible band is wrapped around your forehead to the back of your head, squeezing your entire head tightly. The pain is described as a dull, pressing ache rather than a throbbing pain that pulses like a heartbeat.

Feature	Description
Location	The entire head, especially the back of the head and both temples
Sensation	A pressing sensation like being tightly wrapped in a bandage
Intensity	Mild to moderate, usually does not affect daily activities
Common Triggers	High stress, lack of sleep, staring at screens for too long, tight neck and shoulder muscles

Tension headache, while not extremely severe, is so common that its cumulative impact on quality of life should not be underestimated.

Throbbing Pain on One or Both Sides: Migraine

The name migraine is slightly misleading because it doesn’t necessarily only hurt on one side.

A typical migraine features a throbbing pain that pulses like a heartbeat, and it often comes along with a group of accompanying symptoms.

Feature	Description
Location	Mostly starts at one temple and sometimes spreads to the entire head
Sensation	Throbbing pain, like blood vessels pulsing
Intensity	Moderate to severe, making you just want to lie down and not move
Accompanying Symptoms	Nausea, vomiting, sensitivity to light, sensitivity to sound
Duration	Lasts from 4 to 72 hours

Some people experience a phenomenon called an “aura” about 20 to 60 minutes before a migraine attacks, such as sudden flashes of light, zigzagging bright lines, or temporary blind spots in their field of vision.

If you have experienced this, it is almost certain to be a migraine.

Severe Pain Around the Eye Socket: Cluster Headache

Cluster headache is relatively rare, but the level of pain is so extreme that it is nicknamed the “suicide headache.” Just the name alone tells you how agonizing it is.

Feature	Description
Location	Concentrated in one eye socket or around the eye socket
Sensation	Like a red-hot iron nail piercing into the eye
Intensity	Extremely severe, making it impossible to stay still
Accompanying Symptoms	Tearing in the eye on the same side, conjunctival congestion, nasal congestion or runny nose, drooping eyelid
Duration	15 minutes to 3 hours per episode, recurring repeatedly over several weeks

Cluster headache has a peculiar pattern: it likes to strike at a fixed time, especially in the middle of the night or early morning, waking you up on time like an alarm clock.

Looking at Location Isn’t Enough? These Clues Are Also Key

Location is indeed a great starting point for identifying headache types, but it is not the only basis.

Migraines can sometimes hurt on both sides, and tension headaches occasionally concentrate on only one side. How can you distinguish them further? In addition to “where it hurts,” you should also combine these three observation dimensions.

What Does the Pain “Feel” Like?

Pain Sensation	Possible Headache Type
Dull, pressing, like being squeezed	Tension Headache
Throbbing, pulsing like a heartbeat	Migraine
Sharp piercing, like being stabbed	Cluster Headache

Are There Accompanying Symptoms?

This is often the most powerful clue to distinguish headache types.

Symptoms	Possible Headache Type
Stiff neck and shoulders, pressure on both temples	Typical combination of `tension headache`
Nausea, sensitivity to light, sensitivity to sound	Almost a unique signature of `migraine`
Tearing on the same side, nasal congestion, facial sweating	Pointing towards `cluster headache`

How Long Does It Last? How Often Does It Occur?

Headache Type	Single Episode Duration	Attack Frequency
Tension Headache	30 minutes to several days	Occasional or almost daily
Migraine	4 to 72 hours	Several times a month
Cluster Headache	15 minutes to 3 hours	Frequent attacks for several weeks, then disappearing for several months

Putting the four dimensions of location + sensation + accompanying symptoms + temporal pattern together is like a jigsaw puzzle; the profile of your headache will become clearer and clearer.

Next Time You Have a Headache, Observe Before You Act

When a headache strikes, don’t rush to swallow pills. Take a few seconds to feel it:

Where does it hurt? How does it hurt? Are there any other sensations?

This will not only help you find a more suitable way to relieve it,

A tension headache might be relieved by relaxing your neck and shoulders
A migraine requires resting quietly in a dark, quiet room

If you really need to see a doctor, these observation records can also provide more precise clues, helping you get rid of headache troubles sooner.

Your body is constantly talking to you through “pain.” Learning to understand its language is the very first step to taking care of yourself.

What to Do for a Severe Headache? How to Relieve Headache Pain? Pain Relievers Are Not a Cure-All; Taking Them Wrong Can Make It Worse! Don't Treat All Headaches Lightly, and Don't Scare Yourself Every Time! Watch Out for These Headache Warning Signs You Can't Ignore!

Sun, 24 May 2026 12:05:00 +0800

Everyone has experienced a headache, and that feeling as if your head is about to explode is truly unbearable.

Working all day with a stiff neck and shoulders, staring at a screen for too long with sore eyes, or even not sleeping well the night before—a headache can suddenly come knocking just like that.

When a headache strikes, what else can we do besides reaching for pain relievers? And what are the danger signals that absolutely cannot be delayed?

Practical Methods for Headache Relief

For the most common tension headaches (caused by tight neck and shoulder muscles) and fatigue-induced headaches, there are actually a few drug-free tips to relieve the pain:

Hot and Cold Compresses: Choose the Right Method Based on the Pain Type

Headache Type	Recommended Method	Reason
Tension Headache	Hot compress on neck, shoulders, and back of the head	Relaxes tight muscles and fascia
Migraine	Cold compress on forehead or temples	Reduces the throbbing sensation caused by local vasodilation

A simple way to judge: If your pain is a tightness like the whole head is being squeezed, try a hot compress; if it is throbbing on one side, a cold compress is usually more comfortable.

Stay Away from Stimuli: Give Your Brain a Quiet Environment

Headache发作时，你的大脑处在 过度敏感 的状态。

Bright lights, loud noises, and blue light from phone screens will all multiply and amplify your discomfort.

Find a quiet, dark space and close your eyes to rest for 15 to 30 minutes—this is often much more efficient than pushing through and continuing to work.

Hydrate and Get a Moderate Amount of Caffeine

Have you ever noticed that after being busy all day and forgetting to drink water, your head starts to throb in the afternoon?

Mild dehydration is an easily overlooked cause of headaches. When the body lacks water, blood flow to the brain decreases, triggering a pain alarm. Try slowly drinking 300 to 500 ml of room-temperature water and observe for 20 minutes to see if there is improvement.

A moderate amount of caffeine can also help slightly constrict blood vessels, which has a certain soothing effect in the early stages of a migraine. However, note the word “moderate”—a cup of black coffee is enough. Drinking too much will make you even more sensitive.

Acupressure and Stretching

Using your thumbs to press the Fengchi acupoint (GB20, the depressions on both sides of the hairline at the back of the head) and the Hegu acupoint (LI4, the highest point of the tiger’s mouth) for 30 seconds to 1 minute each time can help relieve tension in the head, neck, and shoulders.

Combined with gentle neck stretches, slowly tilting your head to both sides will produce even better results.

Pain Relievers Are Not a Cure-All: Taking Them Wrong Makes It Worse

Taking pain relievers is the fastest way to relieve pain, and that is fine. But did you know? The timing and frequency of taking them is the real key.

Best Timing for Taking Medication

Pain relievers are best taken as soon as you start to feel a headache coming on. Waiting until you are sweating from intense, unbearable pain to swallow a pill will usually significantly reduce its effectiveness.

This is because once the pain signals are “amplified” to a certain level in the nervous system, simple pain relievers will have a hard time pressing them back down.

“Medication Overuse Headaches” Are Very Real

If you take pain relievers for more than 10 to 15 days per month, your body may develop a paradoxical reaction where the medicine meant to stop the pain actually becomes the cause of the headache.

Scenario	Risk
Taking pain relievers more than 15 days a month	Highly likely to trigger medication overuse headaches
Taking them 10 to 14 days a month	Already in the warning zone
Taking them less than 10 days a month	Normal range of use

This condition is medically known as Medication Overuse Headache (MOH), which can turn occasional headaches into a daily painful struggle.

If you find yourself becoming increasingly reliant on pain relievers, please talk to a doctor about alternative solutions.

Understand Which Category Your Headache Belongs to First

Most headaches people experience do not have a clear “medical cause” and are medically classified as primary headaches.

Classification	Definition	Common Types
Primary Headache	The headache itself is the disease, not caused by other conditions	Tension headache, Migraine, Cluster headache
Secondary Headache	The headache is a “symptom” of another disease	Headaches caused by brain hemorrhage, meningitis, or brain tumor

Primary headaches account for more than 90% of all headaches. Although uncomfortable, they are usually not life-threatening.

So why do we need to specifically mention secondary headaches? Because although they are rare, they can be alarms sounded by serious conditions like brain hemorrhages, infections, or tumors.

And the difference between the two sometimes cannot be determined just by how much it hurts; what you need to pay attention to are other symptoms accompanying the headache.

ER Immediately

If your headache matches any of the following, please drop everything and seek immediate medical attention:

“Thunderclap Headache”: Pain That Explodes Suddenly

Reaching the most severe headache level of your life within seconds to a minute, as if something exploded in your head. This condition, known as a Thunderclap Headache, may indicate a subarachnoid hemorrhage or a ruptured brain aneurysm—every minute is a race against time.

Headache Accompanied by “Neurological Symptoms”

If your headache is accompanied by any of the following conditions, it means something serious might be happening in your brain:

Sudden weakness or numbness in your hands or feet
Slurred speech or inability to speak
Blurred consciousness, drowsiness, or difficulty waking up
Sudden vision deterioration or double vision
Unsteady gait or inability to stand

Headache Accompanied by Signs of Infection

Fever + Headache + Stiff neck—the simultaneous appearance of these three is a classic manifestation of meningitis and requires emergency treatment.

Special Considerations for Age and Medical History

Condition	Description
Experiencing a severe headache for the first time after the age of 50	Need to rule out possibilities like temporal arteritis or tumors
Cancer patients developing a new pattern of headaches	Need to rule out brain metastasis
Ongoing, worsening headache after a head injury	Could be a subdural hemorrhage

These situations are not things you can just “wait and see.”

It is better to go to the ER and find out it was a false alarm than to miss the golden window of treatment.

Don’t Treat All Headaches Lightly, and Don’t Scare Yourself Every Time

The most practical attitude toward headaches is:

Learn self-soothing methods while knowing when to call for help.

Most of the time, a glass of water, a quiet rest, or medication taken at the right time is all it takes to get you back to your normal rhythm.

But if your headache is a sudden explosive pain, carries neurological symptoms, or is combined with fever and a stiff neck, then don’t tough it out—let professional medical staff make the call.

Relax when it’s time to relax, and seek medical attention decisively when needed. Take good care of your head so it can continue to work well for you.

Is Your "Migraine" Actually a Migraine? Migraine is a Disease Name, Not Just "Headache on One Side"! The Most Common Everyday Headache is Tension Headache!

Sun, 24 May 2026 12:00:00 +0800

Have you ever experienced this: you went to the doctor and said you had a "migraine," only for the doctor to finish the consultation and say, "This isn’t a migraine"?

What exactly is a real migraine? And why is it different from what we imagine?

The Name "Migraine" is Actually Quite Misleading

Many people tell doctors in clinics, "I have a migraine—my head hurts on the right (or left) side."

Sounds reasonable, right? Since ‘Migraine’ in Chinese literally means ‘one-sided headache,’ shouldn’t it be a one-sided headache?

The probability of a migraine being on one side is only about 60%—at best, just a bit more than half.

Migraine pain can occur on both sides, at the back of the head, or even constantly change locations.

Some people clearly feel pain right in the middle but are diagnosed with migraines, making them think, "Did the doctor make a mistake?" This is truly a huge misunderstanding.

Migraine is a "Disease Name," Not a "Symptom Description"

The Taiwan Headache Society used a great analogy: just as the "White House" does not refer to just any white palace, but specifically to the office of the President of the United States;

Migraine is a formal diagnostic name for a specific disease, and it has no necessary connection to having a headache on only one side.

Migraine is a neurological disease that has a clear set of diagnostic criteria established by the International Headache Society.

Unilateral headache is just one of the possible features, not the sole basis for judgment.

So, What Does a Real Migraine Actually Look Like?

Since we cannot judge solely by "which side hurts," how can you know if you have a migraine?

According to the diagnostic criteria of the International Classification of Headache Disorders, 3rd edition (ICHD-3), a migraine must meet the following conditions:

Condition	Description
Attacks	At least 5 attacks fulfilling the following characteristics
Duration	Lasting 4 to 72 hours (when untreated or unsuccessfully treated)
Pain Characteristics (at least 2)	Unilateral location, pulsating quality, moderate or severe pain intensity, aggravation by or causing avoidance of routine physical activity
Associated Symptoms (at least 1)	Nausea and/or vomiting, photophobia (sensitivity to light) and phonophobia (sensitivity to sound)

Common Experiences During a Migraine Attack

During a migraine attack, you might experience:

Symptom	Description
Pulsating Throbbing Pain	Pulsating, throbbing pain like a heartbeat, throbbing one beat at a time with your pulse
Nausea and Vomiting	Even actual vomiting in severe cases
Photophobia and Phonophobia	Normal light and sound will make you even more uncomfortable
Pain Aggravated by Activity	Walking or climbing stairs makes the headache worse, making you want to just lie quietly in a dark room

Furthermore, this pain can last from several hours to several days once it starts, severely affecting daily routines and work.

Some People Also Experience "Aura"

About 10% to 20% of migraine sufferers experience neurological warning signals before the headache starts:

Flashing spots of light or wavy shadows in the field of vision
Feeling numbness or weakness on one side of the body
Sudden slurred speech or difficulty speaking

These aura symptoms usually develop over 20 to 30 minutes, followed closely by the onset of the headache.

If It’s Not a Migraine, What is My Usual Headache?

After hearing the description of migraine, you might think: "So what’s going on when I get a headache from stress or poor sleep?"

The vast majority of headaches we encounter in daily life are tension headaches (also known as tension-type headaches).

Various studies show that 30% to 78% of the general population will experience at least one tension headache in their lifetime.

Migraine vs. Tension Headache

These two types of headaches are often confused, but the differences are quite distinct:

Comparison	Migraine	Tension Headache
Pain Sensation	Pulsating throbbing pain (throbbing like a heartbeat)	Tightness, pressure (like a band squeezing the head)
Pain Location	Unilateral or bilateral, may shift	Usually both sides of the head, forehead, or back of the head
Severity	Moderate to severe	Mild to moderate
Duration	4 to 72 hours	30 minutes to several days
Nausea/Vomiting	Common	Rare
Sensitivity to Light/Sound	Common	Rare
Physical Activity	Aggravated by physical activity	Usually unaffected or slightly relieved by activity

Tension headaches are mostly related to stress, fatigue, poor posture, or muscle tension. Resting a bit and relaxing your neck and shoulders usually helps.

In comparison, migraines present much stronger pain, come with more symptoms, and have a greater impact on life.

Why Do We Need to Distinguish Between Headache Types?

You might think: "I’ll just take painkillers for a headache anyway, why bother telling them apart?"

This line of thinking is actually quite dangerous.

The Treatments Are Completely Different

Headache Type	Common Treatments
Tension Headache	General pain relievers (like Acetaminophen, Ibuprofen), muscle relaxants, lifestyle adjustments
Migraine	May require specific Triptans, and severe cases might need CGRP inhibitors or preventive treatment

Migraine has its own exclusive treatments and strategies, which are vastly different from how general headaches are managed.

If you treat a migraine as a common headache, the results will likely be poor, and it will keep recurring.

Overusing Painkillers Makes It Worse

Overusing pain relievers long-term can actually trigger "medication overuse headaches", making headaches more frequent and harder to treat.

Among chronic migraine sufferers, many unknowingly develop a dependency on painkillers, falling into a vicious cycle of "the more they hurt, the more they take, and the more they take, the more they hurt."

Long-term Risks of Ignoring Migraines

If you suffer from migraines and continue to ignore them without proper management:

Migraine can progress from occasional attacks to chronic migraine (headaches occurring 15 or more days per month for more than 3 months)
Long-term migraine sufferers face a higher risk of depression and anxiety
Migraine is also one of the top three causes of workplace productivity loss worldwide

Don’t Let the Name "Migraine" Fool You Anymore

Next time you get a headache, why not take a few seconds to observe:

Is it a dull tightness, or is it throbbing along with your heartbeat? Do you feel nauseous? Is the light exceptionally glaring?

These tiny details can help you understand your headache better and provide the doctor with more precise clues when you seek medical care.

If your headaches are frequent enough to affect your life, please don’t just endure it with painkillers. Consult a specialist in neurology for a proper diagnosis. Identifying the exact type of headache is the only way to treat it effectively and free yourself from its grip.

Why Do Blood Vessels Prefer Low Sodium and High Potassium? Does Low Sodium Cause Heat Stroke, and Does Excess Sodium Suffocate Blood Vessels? Can Drinking Only Plain Water Cause 'Water Intoxication'? Besides Sodium and Potassium, What Other Electrolytes Does the Body Need? How to Safely Replenish After Sweating? Learn to Protect Blood Vessels in Daily Life to Stay Away from Stroke and Cardiovascular Diseases!

Sat, 23 May 2026 17:40:00 +0800

We often hear doctors earnestly advise: “Keep it low sodium and high potassium; it’s best for your cardiovascular health!”

But have you ever wondered why drinking only plain water after sweating heavily in summer can instead trigger headaches, cramps, or even fainting?

This is actually a strong warning signal from the body for “low sodium.”

Blood vessels prefer low sodium, but the body absolutely cannot do without sodium.

This seemingly contradictory relationship is the most interesting and important lesson in electrolyte balance.

Why Do Blood Vessels Prefer a Low-Sodium, High-Potassium Environment?

Let’s first look at why the medical community has always emphasized “low sodium and high potassium is good for cardiovascular health.”

Too Much Sodium: Blood Vessels Are Suffocated by High Pressure

Sodium keeps water inside blood vessels. When you eat too salty, a large amount of sodium enters the bloodstream, and the body will forcibly draw water from cells and tissues into blood vessels.

The volume of water inside the vessels increases suddenly, and pressure naturally spikes.

Over time, blood vessels become like a high-pressure hose turned up to the maximum, with the walls constantly hit by rushes of water, eventually hardening and losing elasticity.

The Role of Potassium: The Relaxant for Blood Vessels

Potassium is the natural opponent of sodium. It helps the body excrete excess sodium and relaxes the smooth muscle of blood vessel walls, reducing the pressure they bear.

Ion	Effect on Blood Vessels
Sodium	Retains water in vessels; vessels become pressurized and tense
Potassium	Helps vessels drain and relax, reducing pressure

For cardiovascular care, low sodium and high potassium is indeed the golden rule.

Since Sodium Raises Blood Pressure, Is It the Less, the Better?

Sodium is an essential item for maintaining nerve transmission and muscle contraction.

Our brain needs to send signals, our heart needs to beat, and our muscles need to contract—all of which require sodium ions to shuttle in and out of cells to generate electrical signals.

If the sodium concentration in the blood drops too low, the body’s “power plant” will directly shut down.

What Is Hyponatremia (Water Intoxication)?

When sweating heavily in summer, sodium is lost in large quantities with sweat.

If you only desperately gulp down pure water at this time, the sodium in the blood will be diluted to a dangerous concentration.

This is hyponatremia, commonly known as water intoxication.

What Happens to the Body with Hyponatremia?

Stage	Body Response	Cause
Mild	Headache, dizziness, nausea and vomiting	Blood `sodium` concentration drops; `brain` cells begin to absorb water and swell
Moderate	Muscle cramps (heat cramps), general weakness and limpness	Insufficient nerve transmission electrical signals; muscles cannot contract normally
Severe	Confusion, convulsions, coma	Brain cells suffer severe edema, getting pressed against each other inside the hard skull

Brain cells are the first to suffer because they are locked inside the hard skull and have no room to swell.

This is why people suffering from heat stroke or heat exhaustion will experience severe headaches or even faint.

Besides Sodium and Potassium, What Other Electrolytes Does the Body Need?

The human body does not only need sodium and potassium. To keep muscles and blood vessels functioning perfectly, we need a complete electrolyte squad.

Electrolyte	Main Function	What Happens When Lacking	Good Food Sources
Sodium	Maintains blood pressure, transmits nerve signals	Dizziness, cramps, coma	Table salt, sports drinks
Potassium	Excretes excess sodium, stabilizes blood pressure	Muscle weakness, constipation, cramps	Bananas, guavas, water spinach
Magnesium	Relaxes nerves and muscles, improves sleep	Prone to cramps, anxiety, insomnia	Nuts, dark green vegetables, dark chocolate
Calcium	Controls heart muscle contraction, strengthens bones	Palpitations, osteoporosis	Tofu, dried small fish, milk

Magnesium Ion: The Overlooked Master of Blood Vessel Relaxation

Magnesium and potassium are great partners; it is specifically responsible for relaxing blood vessel smooth muscles and soothing nerves.

People lacking magnesium are prone to vascular spasms, high blood pressure, and also insomnia and midnight leg cramps.

Nuts (cashews, almonds) and whole grains (brown rice, oats) are excellent sources of magnesium.

How on Earth to Replenish Safely After Sweating?

Now that we understand the importance of electrolytes, how should we replenish them in different scenarios?

Decide What to Replenish Based on Sweating Level

Scenario	What to Drink	Why
In air-conditioned room, no sweat	Pure water is fine, paired with high-potassium fruits and vegetables to excrete sodium	`Sodium` is not lost; replenishing pure water is enough
Light exercise, slight sweating	Mainly pure water	The amount of `sodium` lost from short-term sweating is not enough to cause danger
Heavy sweating under hot sun for over 1 hour	Sports drinks (can be diluted 1:1 with pure water), or a pinch of salt in water	`Sodium` has been lost in large amounts with sweat; drinking only pure water triggers low sodium
Severe diarrhea or vomiting	Oral rehydration solution or sports drinks	The gastrointestinal tract loses massive water and electrolytes; synchronous replenishment is needed

How to Tell You Need to Replenish Electrolytes?

Sweat hurts when running into eyes
Clothes dry with white salt stains
Starting to feel a dull headache or muscle twitching

The appearance of these signals means electrolytes have already begun to unbalance, and you can no longer drink only pure water.

What Are the Principles of Controlling Sodium and Replenishing Sodium?

Many people find controlling electrolytes complicated, but you actually just need to remember one principle:

Replenish more potassium to excrete sodium when not sweating (prevent high blood pressure), and remember to replenish sodium when sweating heavily (prevent heat stroke).

State	What You Should Do	Why
Usually (air-conditioned room, daily life)	Dip less sauce, drink less salty soup, eat more fruits and vegetables	`Sodium` is already sufficiently ingested from diet; `potassium` is needed to excrete excess `sodium`
After heavy sweating	Drink beverages containing electrolytes, or add a little bit of salt to water	`Sodium` has been lost in large amounts with sweat; drinking only pure water will instead dilute blood `sodium`
After eating a heavy-flavored big meal	Drink large amounts of water immediately, paired with high-potassium fruits	Helps blood vessels dilute the surged `sodium` and triggers the kidneys’ sodium excretion mechanism

The Most Recommended Daily Electrolyte Dietary Method

In clinical medicine, there is a set of dietary methods specifically designed to lower blood pressure and protect blood vessels, called the DASH Diet.

Its core is “high potassium, high magnesium, high calcium, and moderate sodium”:

Food Item	Main Purpose	Recommended Intake
Vegetables and Fruits	Replenish potassium and magnesium	Eat every day
Whole Grains	Replenish magnesium and fiber	As snacks
Dairy or Soy Products	Replenish calcium	Consume in moderation
Control Sodium	Avoid excessive pressure on blood vessels	Do not intentionally add salt when not sweating heavily

Blood vessels indeed prefer low sodium, but the body absolutely cannot do without sodium.

Grasping the principle of “not excessive normally, replenish wisely when sweating” to let the electrolytes in the body perform their respective duties is the smartest way of protection.
