Clinical data show that more than 70% stroke patients will yawn frequently 5~ 10 days before onset.

Why do people yawn easily in spring?
Yawning is a physiological instinct of human beings. Yawning during fatigue and lack of sleep is medically considered to be caused by cerebral ischemia and hypoxia.
Yawning can dilate the lungs, reduce intracranial pressure, increase the amount of blood flowing back and out from veins, thus increasing the oxygen content in the blood, lowering the temperature of the brain and improving the hypoxia state of the brain.
This can be regarded as a self-protection behavior of the body.
People are particularly prone to yawn in spring, mainly because after a winter's "dormancy", the contracted epidermal capillaries will gradually expand in warm spring;
When the blood flow of blood vessels in the skin is filled, the blood flow in the brain will be reduced compared with that in winter, and the brain will suffer from ischemia and hypoxia, especially the brain stem.
So it is normal to yawn 1 ~ 2 times every one or two hours in spring.
Yawning is a precursor to stroke.
If you yawn continuously, it means that the brain is obviously hypoxic, so you should pay attention at this time.
Zhong pointed out that if there are stroke risk factors such as hypertension and arteriosclerosis, and frequent continuous yawning, accompanied by limb weakness, even crooked mouth and unclear speech, you must seek medical attention in time, because this is likely to be the early stage of stroke.
Stroke, commonly known as "stroke", is the first cause of death in China. Zhong reminded that some young people should be vigilant if they still yawn after getting enough sleep without knowing whether they have high risk factors for stroke.
"Yawning is controlled by the brain stem. In the event of frequent yawning without obvious incentives, it is recommended to go to the hospital for magnetic resonance examination to rule out hypoxia caused by brain stem lesions. "
In addition to yawning frequently, the possibility of stroke should also be considered when patients suddenly have any of the following symptoms:
1. A limb (with or without face) is weak or numb.
2. One side of the face is numb or the corners of the mouth are skewed.
3. Unable to speak or understand the language clearly.
4. Keep your eyes on one side.
5. Loss or blurred vision in one or both eyes.
6. Dizziness with vomiting.
7. Severe headache and vomiting that were rare in the past.
8. Consciousness disorder or spasm.
Among them, the first three symptoms are the most common.
Three formulas to help you identify strokes.
If you find a stroke, you should call 120 immediately, let the patient lie on his side in a flat place to keep warm, take out the foreign body in his mouth, and remember the onset time or the last normal body time.
In order to facilitate rapid identification, experts have compiled a formula for symptoms.
The first one is: I'm vague, my mouth is crooked, and I ran to the hospital without raising my arm.
The second is a quick formula:
Face shape: whether the face is symmetrical when smiling;
Arm: whether one side droops when lifting the arm;
Pronunciation: whether the pronunciation is strange;
Time: Call 120 in time.
Third, China's unique 120 principle:
"1" stands for "see 1 asymmetric face"; "2" stands for "whether both arms are weak unilaterally"; "0" stands for "Listen (zero) to see if the speech is clear"; If the above symptoms appear, you should call "120" immediately.
Prevent stroke and pay attention to the details of life.
Although stroke often attacks people unprepared, it is an acute chronic disease that can be prevented and cured.
Wang Yongjun said that the risk factors of stroke include:
A study published in The Lancet found that 90% of strokes are caused by risk factors:
If blood pressure is well controlled, stroke can be reduced by 48%;
If you increase physical activity, you will reduce the stroke by 36%;
If the diet is healthy and the structure is reasonable, there will be 19% stroke that can be prevented;
If you quit smoking, you will reduce 12% stroke;
If atrial fibrillation is well controlled, 9% stroke can be prevented;
If diabetes is well controlled, stroke can be reduced by 4%;
Restricting drinking can reduce 6% of strokes;
Learning to release stress can also prevent 6% stroke;
Controlling blood lipids will reduce stroke by 27%.
Among them, hypertension is the most important controllable factor and an important goal to reduce the global stroke burden. Reasonable drugs and healthy diet can effectively lower blood pressure and reduce the occurrence of stroke.
For China residents, besides high blood pressure, lack of physical activity is also an important risk factor, so it is suggested to keep exercising.
