Life should be regular to prevent excessive fatigue, because extreme fatigue will lower blood pressure. To maintain a good mental state, properly strengthen exercise, improve physical fitness, improve the regulation function of neurovascular, accelerate blood circulation, and reduce the onset of orthostatic hypotension, the elderly should choose exercise according to environmental conditions and their own physical conditions, such as Tai Ji Chuan, walking, aerobics, etc.

Adjust diet

It is not advisable to eat too much every meal, because eating too much will reduce the blood flowing back to the heart; Old people with low blood pressure can drink some salty boiled water every morning, or eat a slightly salty diet to increase water. More water entering the blood can increase blood volume and raise blood pressure; Drink tea in moderation, because caffeine in tea can excite the respiratory center and cardiovascular system; Moderate drinking (wine is the best, or beer is the best, not hard liquor) can excite sympathetic nerves, speed up blood flow, promote heart function and reduce blood viscosity.
