After autumn, the weather is getting colder and the human immunity is declining. What diseases should be prevented in autumn?

Prevention of cardiovascular and cerebrovascular diseases

When the temperature rises above 32℃, on the one hand, a lot of human sweat evaporates, dissipating heat and lowering summer heat, and its metabolism is completed by the blood flow in subcutaneous blood circulation which is several times higher than usual. Under this extraordinary blood circulation, emotional instability can cause vasospasm and elevated blood pressure; Loss of body fluids increases blood viscosity; Blood vessels dilate to dissipate heat and induce bleeding.

On the other hand, the limited blood of the human body will rush to the skin in a short time, which will inevitably lead to a sharp decrease in cerebral blood flow. For the elderly with poor cardiovascular regulation and cerebral arteriosclerosis, it is also easy to induce stroke due to cardiac and cerebral infarction.
