The old man beware of a stroke
it is well known that people often make a few yawns when they feel tired and can make a temporary relief of fatigue. However, the middle and old people, especially those of hypertension and cerebral arteriosclerosis, may be ischemic brain if they often yawn. Warning of stroke should be improved.
70% to 80% of the patients with ischemic stroke, about 1 weeks before the onset of the disease, will frequently yawn because of cerebral ischemia and hypoxia. The reason is that people with hypertension and cerebral arteriosclerosis, because of atherosclerosis, narrowing of the lumen, reduced the elasticity of the blood vessels, reduce the blood flow to the brain, and the brain is very sensitive to oxygen, which accounts for only about 2% of the body weight, but consumes about 25% of the total oxygen demand,
, therefore, when When the brain is ischemic or hypoxic, it causes frequent yawns. Yawning can reduce the pressure in the thoracic cavity, increase the blood volume of the upper and lower vena cava recirculation of the heart, increase the output of the heart, and improve the ability of the brain cells to supply blood. But this improvement is temporary. Therefore, frequent yawning often indicates that ischemic stroke may occur in the near future.
therefore, the middle-aged and the elderly, especially those with cardiovascular and cerebrovascular diseases, if there is no inducement of frequent yawning, should not be taken lightly, should go to the hospital in time, under the guidance of the doctor, to treat hypertension, high blood fat and so on active treatment.
, drink food should be light, avoid high fat diet, Smoking and limiting alcohol: small dose of aspirin to reduce the aggregation of red blood cells and platelets, prevent thrombosis: to keep the spirit optimistic, emotional stability, prevent excitement, all of these have a positive effect on the prevention of ischemic stroke.
