The elderly frequently yawned and warned
Mortality, when people feel tired, they often yawn a few times, which can relieve the temporary recovery of fatigue. However, middle-aged and elderly people, especially those with high blood pressure and cerebral arteriosclerosis, may yawn on a large scale if they yawn frequently.The harbinger should be vigilant.
80% of patients with graded stroke have a yawning phenomenon due to enlarged brain and hypoxia in the first week or so before the onset of the disease.
The reason is that high blood pressure, high blood pressure, cerebral arteriosclerosis, due to atherosclerosis, narrowing of the lumen, reduced elasticity of the blood vessel wall, resulting in a decrease in the amount of blood flowing to the brain, and the brain is very sensitive to oxygen, accounting for only 2About % of the brain, but it consumes about 25% of the whole body’s oxygen demand. Therefore, when the brain is ischemic and lacks oxygen, it will cause yawning frequently.
Yawning reduces the pressure drop in the thoracic cavity, the blood volume of the heart is increased by the superior and inferior vena cava, the blood output of the heart is increased, and the blood supply capacity of the brain cells is improved.
However, this improvement is temporary, so frequent yawning often indicates that a large-scale stroke may occur in the near future.
Therefore, middle-aged and elderly people, especially those with cardiovascular and cerebrovascular diseases, should not be taken lightly when they have repeated yawns without incentives. They should go to the hospital for examination in time and actively treat high blood pressure and high blood fat under the guidance of doctors.
At the same time, diet should be light, avoid high-fat diet, quit smoking and alcohol restriction: oral low-dose aspirin to reduce red blood cells, platelet aggregation, prevent thrombosis: pay attention to maintain mental optimism, emotional stability, prevent agitation, these are against disease-preventing brainThe occurrence of stroke has a positive effect.
