What would you do if a family member next to you suddenly couldn’t even say a simple “Hello” clearly?

During a stroke, every single minute of delay costs the brain approximately 1.9 million brain cells.

In a state of panic, many people make the wrong moves, such as feeding water, giving medicine, or even using a needle for bloodletting, which only pushes the situation into a more dangerous state.

Learning how to correctly recognize a stroke and dispelling fatal first-aid myths are life-saving skills that everyone should have.

What Warning Signs Does the Body Show When a Stroke Strikes?

The most prominent feature of a stroke is “suddenness”.

One second you are chatting and laughing, and the next second your body has a problem. The internationally recognized acronym for identification is FAST:

Letter	English	Test Method	Key Observation
F	Face	Ask the person to smile	Check if both sides of the face are symmetrical, and if there is a drooping corner of the mouth on one side
A	Arm	Ask the person to raise both arms	Check if one arm drifts downward weakly
S	Speech	Ask the person to say “The weather is very nice today”	Check if they are slurring their words, or completely unable to speak
T	Time	Record the exact hour and minute symptoms appeared	Immediately call 119, and inform them of the onset time

If any one of these three actions cannot be done, it is highly likely to be a stroke, and the patient must be sent to the hospital immediately.

Besides FAST, What Other Danger Signals Exist?

FAST can catch most strokes, but several other warning signs should not be ignored either:

Signal	Explanation
Sudden numbness on one side of the body	Sudden loss of sensation on one side of the face, arm, or leg, unlike the feeling of a limb falling asleep
Sudden vision abnormalities	Sudden loss of vision in one eye, like a black curtain falling; or seeing double images
Sudden trouble walking	Staggering as if drunk, with difficulty even standing steadily
Explosive, severe headache	Unprecedented severe pain, like being struck by lightning, commonly seen in hemorrhagic stroke
Sudden difficulty understanding speech	Hearing is normal, but the brain seems to freeze and cannot comprehend what others are saying

Can We Perform Bloodletting for a Stroke? Is Feeding Water or Medication OK?

When facing an emergency, elders often say “quickly prick the fingers with a needle for bloodletting” or “give them a blood pressure pill to swallow.”

These folk remedies are not only useless, but can also be fatal.

Three Fatal Myths

Myth	Reality	Why It Is Dangerous
Pricking fingers to let blood clears blood vessels	Bloodletting cannot clear the blood clot inside cerebral blood vessels	Painful stimulation can make blood pressure spike even higher, accelerating the worsening of hemorrhagic stroke
Quickly feed water or food	The swallowing nerves might already be damaged during a stroke	Water and food can easily be choked into the lungs, leading to aspiration pneumonia or even suffocation
Administer blood pressure medicine on your own	During ischemic stroke, the brain intentionally raises blood pressure to save itself	Lowering blood pressure without authorization makes the brain more oxygen-deprived, and the damaged area expands instead

Where Did the Saying of Bloodletting Come From?

From the perspective of Traditional Chinese Medicine, the technique of pricking fingers to let blood is called Shi Xuan Bloodletting, but it is not used for emergency rescue of stroke.

Shi Xuan Bloodletting uses stimulation of peripheral nerves to keep the patient awake. This is a medical procedure and should only be performed by a professional practitioner of TCM after determining it is an ischemic stroke.

For ordinary people to perform this at home, the risks far outweigh the benefits.

What Are the Correct Stroke Emergency Response Steps?

The only correct way is simple, but must be executed calmly and rapidly:

Step	What to Do	Why It Matters
Step 1	Immediately call 119	Emergency medical personnel are on the ambulance and can notify the hospital’s Stroke Green Channel in advance to prepare
Step 2	Precisely record “the last time they were seen normal”	The doctor needs this time to decide whether the life-saving drug can be administered
Step 3	Place the patient on their side	Prevents vomit or the tongue from blocking the trachea to avoid suffocation
Step 4	Loosen tight clothing like collars and neckties	Keep the airway unobstructed
Step 5	Stay by their side and soothe their emotions	Anxiety will cause blood pressure to spike higher, worsening brain damage

Do not feed anything, do not move the patient’s head, and do not drive to a small clinic on your own.

If you must transport the patient yourself, go directly to a large hospital equipped with stroke emergency response capabilities, do not waste time sending them to a general clinic.

Why Can “Recording the Time” Save a Life?

You might wonder, why is the last letter of the FAST acronym T (Time)?

Because the life-saving medicine for stroke has a strict time limit.

Time Decides What Weapons Doctors Can Use

Treatment Method	Time Limit	Working Principle
Intravenous Thrombolytic Agent (rt-PA)	Within 4.5 hours of onset	Use drugs to dissolve the blood clot blocking the blood vessel
Arterial Thrombectomy	Within 6 to 24 hours of onset	Insert a catheter into the brain blood vessel to physically pull out the blood clot

If the family cannot provide a clear time of onset, doctors do not dare to use the thrombolytic drug blindly, because administering it past the time limit will instead increase the risk of cerebral hemorrhage.

The “exact hour and minute” you record could be the only key to whether your family member can clear their blood vessels and save their brain cells.

What Happens After Reaching the Hospital?

The hospital will activate the Stroke Green Channel, and all examinations and treatments will be fast-tracked:

Time	Explanation
0-10 minutes	Nurses immediately measure blood sugar (to rule out hypoglycemia mimicking stroke), draw blood, and evaluate severity
10-25 minutes	Urgent transfer to Computed Tomography (CT) to confirm if the blood vessel is blocked or ruptured
25-45 minutes	The doctor decides on using a thrombolytic agent or thrombectomy based on CT results and onset time
Within 60 minutes	Administration of medication is completed, and the patient is transferred to the Stroke Intensive Care Unit for close monitoring

The international medical standard strives to complete “Door-to-Needle” within 60 minutes.

If Symptoms Clear Up Quickly, Do I Still Need to See a Doctor?

There is a condition called “Mini-Stroke” (Transient Ischemic Attack, TIA).

The symptoms are exactly the same as a stroke, but they usually recover on their own within a few minutes to 24 hours.

Never assume that because you feel better, everything is fine.

A mini-stroke is the ultimate ultimatum sent by the brain. It means that the cerebral blood vessels are already severely narrowed or have unstable plaques, and the probability of a major stroke occurring in the future is extremely high.

Even if symptoms disappear within a few minutes, you must go to the emergency room immediately for a complete examination, allowing the doctor to evaluate the condition of the blood vessels and intervene early.

Facing a stroke, the best preparation we can make is to engrave the FAST acronym in our minds, and bravely say no to folk remedies.

At the critical moment, your calm judgment and that phrase “when it started” can save your family member’s brain and future.

Imagine the brain’s control center, which usually runs smoothly, suddenly experiencing a ‘blackout’ due to a blocked or ruptured blood vessel.

One moment a person is perfectly fine, and the next, their limbs stop working and their speech becomes slurred.

This is what we commonly call a stroke.

Even if a life is saved, a stroke often leaves behind severe long-term disabilities.

But the good news is that up to 90% of strokes are linked to controllable risk factors. In other words, we have a chance to close the door before it strikes.

What is a Stroke? What is the Difference Between Ischemic and Hemorrhagic Stroke?

The medical term for a stroke is a cerebrovascular accident (CVA). In plain language, it means a blood vessel in the brain suddenly gets blocked or ruptures, causing:

Brain cells to be deprived of blood and oxygen supplies, beginning to die within just a few minutes.

Strokes are mainly divided into two major types:

Type	Proportion	Cause	Everyday Analogy
Ischemic Stroke	Approx. 80%	The blood vessel is blocked by a blood clot, preventing blood flow	A water pipe clogged by debris
Hemorrhagic Stroke	Approx. 20%	The blood vessel ruptures and bleeds, compressing brain tissue	A water pipe bursting under too much pressure

Regardless of the type of stroke, as long as

brain cells are deprived of oxygen for more than a few minutes, they will die, and dead brain cells cannot regenerate.

This is why the rescue speed for a stroke is so critical.

How to Recognize if Someone is Having a Stroke?

The biggest characteristic of a stroke is its “suddenness”.

One second they are laughing and talking, and the next, something is terribly wrong with their body.

There is an internationally recognized acronym for identifying a stroke called FAST:

Letter	English	Action	Key Observations
F	Face	Ask the person to smile	Check if both sides of the face are symmetrical, and if one corner of the mouth is drooping
A	Arm	Ask the person to raise both arms	Check if one arm drifts downward weakly
S	Speech	Ask the person to repeat a simple phrase	Check if their speech is slurred or strange
T	Time	Note the time	Immediately call 119/911 for emergency help

If a person fails even one of these three tasks, it is highly likely to be a stroke. Act immediately and call for help.

Besides FAST, What Other Stroke Warning Signs are Easy to Ignore?

Sudden numbness on one side of the body, which is different from limbs falling asleep, but rather losing sensation in half of the body
Sudden vision changes in one or both eyes, like a black curtain blocking the view
Sudden trouble walking, losing balance and stumbling like being drunk
A severe headache that comes out of nowhere, sometimes accompanied by projectile vomiting
Sudden difficulty understanding what others are saying, or being unable to speak at all

What is the First Thing to Do When Someone Has a Stroke?

Many people’s first reaction when encountering a stroke is to feed the patient water, give them blood pressure medication, or even prick their fingers to let blood out.

All of these are extremely dangerous, incorrect behaviors.

What You Must Absolutely NOT Do

Common Myths	Why It is Dangerous
Pricking fingers to let blood	Bloodletting cannot clear blood vessels, and the pain may actually cause blood pressure to spike higher
Feeding water or food	A stroke may impair swallowing function, and feeding can easily cause choking or aspiration pneumonia
Giving blood pressure medicine	During an `ischemic stroke`, the brain intentionally raises blood pressure to save itself; lowering it can make oxygen deprivation worse
Waiting to see if it gets better	For every 1 minute delayed, the brain loses about 1.9 million brain cells

Correct Emergency Steps

Immediately call emergency services (119/911) to get an ambulance.
Accurately record the time when the patient was last seen normal (this is critical for doctors to decide if life-saving drugs can be used).
Place the patient in a side-lying position to prevent vomit from blocking the airway.
Loosen tight clothing around the collar or tie to keep the airway clear.
Stay by the patient’s side to calm them down, letting them know that help is on the way.

How Do Doctors Treat a Stroke After Arriving at the Hospital?

Upon arrival at the hospital, doctors will initiate a stroke green channel, where all examinations and treatments are fast-tracked and prioritized.

Treatment Within the Golden Window

Treatment	Applicable Condition	Principle
Intravenous Thrombolysis (rt-PA)	Within 4.5 hours of onset, Ischemic Stroke	Uses drugs to dissolve the blood clot
Endovascular Thrombectomy	Within 6 to 24 hours of onset, large vessel occlusion	Uses a catheter to go deep into cerebral vessels and extract the clot

The earlier the blood vessel is opened, the more brain cells can be saved.

However, thrombolytic agents carry about a 6% risk of causing brain hemorrhage, so a doctor must conduct a thorough evaluation before use.

This is also why an accurate onset time is so important, because it directly determines whether the doctor can prescribe this life-saving drug.

Can You Recover from a Stroke?

Although dead brain cells cannot be brought back to life, the brain has an amazing ability called neuroplasticity.

Through continuous and repetitive rehabilitation stimulation, other healthy areas of the brain can ‘rewire’ to take over some of the lost functions.

It is like when a main highway collapses, we can widen existing roads or take alternative routes to reach the destination just the same.

The first six months after a stroke is the golden window for rehabilitation. Through physical therapy, occupational therapy, and speech therapy, many patients can progress from being bedridden to regaining self-care.

Who is at High Risk for a Stroke?

You might think that strokes only happen to the elderly.

In reality, chronic diseases like high blood pressure and diabetes are the true silent killers of blood vessels.

Controllable Risk Factors

Risk Factor	Damage to Blood Vessels
High Blood Pressure	The biggest driver of strokes. Long-term high pressure hardens blood vessels and causes loss of elasticity
High Blood Lipids	Bad cholesterol builds up as grease in vessel walls, forming atherosclerosis
Diabetes	Blood vessels are constantly soaked in sugary blood, causing inflammation and accelerating hardening. Stroke risk is 2-3 times that of others
Atrial Fibrillation	An irregular heartbeat causes blood to pool and clot, which can travel to the brain and cause an ischemic stroke
Smoking	Nicotine directly damages the vascular lining, doubling the stroke risk compared to non-smokers
Obesity & Lack of Exercise	Prolonged sitting slows metabolism, directly leading to the ’three highs’
Excessive Drinking	Binge drinking causes blood pressure to fluctuate wildly, increasing the risk of hemorrhagic stroke

Unchangeable Innate Factors

Factor	Description
Age	After age 55, the risk of stroke doubles with every decade
Family History	If parents or siblings have a history of cardiovascular disease, your own risk increases significantly

How to Prevent a Stroke in Daily Life?

Up to 90% of strokes are linked to controllable risk factors.

In other words, by controlling your blood pressure and improving your lifestyle, you can dramatically reduce the chance of a stroke knocking on your door.

What to Eat to Protect Your Blood Vessels?

The dietary pattern most recommended by the medical community for vascular health is the Mediterranean diet, which focuses on eating natural whole foods and minimizing processed items:

Dietary Strategy	Implementation	Benefits to Blood Vessels
Switch to Good Oils	Cook with olive oil, camellia oil, or canola oil	Reduces bad cholesterol and clears grease from vessel walls
Eat More Deep-Sea Fish	Eat fish like mackerel, salmon, or saury twice a week	`Omega-3` helps fight inflammation and reduces clot formation
Eat Fruits & Veggies Daily	Eat more spinach, water spinach, bananas, and guavas	`Potassium` helps excrete excess sodium, acting as a natural blood pressure reducer
Less Sodium & Processed Foods	Use fewer dipping sauces, drink less hot pot soup, and avoid processed foods	Directly reduces stress on blood vessels

How to Adjust Your Lifestyle?

Lifestyle Strategy	Description
Quit Smoking Immediately	As soon as you quit smoking, your stroke risk begins to decline steadily
Exercise Regularly	Cardio exercise 3 times a week, 30 minutes each time (brisk walking, swimming) helps vessels release nitric oxide to stay elastic
Get Enough Sleep	Chronic sleep deprivation spikes stress hormones, keeping blood vessels tense all day
Beware of Winter Temperature Swings	Move around in bed before getting up; start showering by spraying warm water on limbs first to prevent vessels from constricting sharply

How Important is Regular Health Checkups?

The scariest thing about atherosclerosis is that it is almost completely asymptomatic in its early stages.

Even if a blood vessel is 50-60% blocked, you might not feel a thing.

For people over 40 or those with the “three highs”, it is recommended to add a carotid ultrasound during health checkups.

This is a painless, radiation-free test that allows doctors to directly see whether the large blood vessels in the neck have plaque buildup or narrowing, catching stroke risks early.

By controlling blood pressure, eating healthily, and staying active, strokes are highly preventable.

Protect your brain’s blood vessels, starting with a spoonful of good oil at the table and a brisk walk today.
