This increase in blood pressure caused by cold is called cold pressurization reaction. The typical manifestations of cold pressurization reaction are numbness of limbs, cold hands and feet and headache. It is not surprising that the blood pressure of the elderly is relatively high and they are prone to headaches in winter. This kind of headache can be tried in the first case of Nong Yu, which is very good.

Therefore, it is best to wear a scarf and hat to keep warm when going out in cold weather; When you walk from outdoor to indoor with heating, open the window to cool down first, so as to avoid the headache caused by high temperature and the body has no time to adapt. In winter outdoor sports, it is best to wear a hooded coat or hat to avoid vasodilation during exercise, but the epidermis is exposed to cold air, which leads to poor vascular regulation; If you sweat during exercise, dry it with a towel or handkerchief as soon as possible to avoid headache caused by sweating and catching cold.
