How to prevent fainting?

STEP 1 Pay Attention to Life

[Benign] fainting only needs to pay attention to the details of life.

(1) Avoid standing for a long time or suddenly standing up after sitting and lying for a long time.

Standing for a long time will cause redistribution of blood throughout the body. Sudden standing up may lead to instantaneous hypotension (postural hypotension), which will cause insufficient blood supply to the brain and lead to fainting.

(2) Drink more water [4]

Exercise or heat may lead to water loss in the body. Attention should be paid to drinking more water during exercise or in hot weather.

(3) Eat regularly and quantitatively to ensure nutrition

Prevent anemia and hypoglycemia.

2. Regular physical examination to detect potential diseases

Middle-aged and elderly people should pay attention to physical examination, find potential heart diseases, etc., treat and prevent them as soon as possible, and avoid serious injuries caused by fainting.
