Cerebrovascular disease is mostly seen in people with hypertension, cerebral arteriosclerosis, diabetes, heart disease, obesity, etc. It is especially common when overworked and with violent mood swings. Therefore, effective treatment and control of hypertension and avoidance of excessive mental tension and fatigue are the main links in the prevention of cerebrovascular disease. However, climate change is also a factor that can not be ignored to induce cerebrovascular disease. According to the survey, about more than half of the patients, occur in the late autumn and early winter when the climate changes suddenly. This is because: 1, low temperature can make the body surface blood vessel elasticity decreased, peripheral resistance increased, blood pressure increased, and then lead to cerebrovascular rupture bleeding. 2, cold stimulation can also make sympathetic excitation, increased secretion of adrenocorticotropic hormone, which causes small arteries to contract spasmodically, increasing the peripheral resistance, blood pressure increases. 3, cold can also increase the fibrinogen content in the blood, the blood concentration increases, prompting the formation of emboli in the blood and the onset of disease.
