There are many possible reasons for dizziness after exercise. Exercise-induced hypoglycemia is common, which is due to the lack of calories in the body and the decrease of blood sugar content when the human body exercises a lot, and blood sugar mainly comes from the digestion of food. In the process of exercise, there is no continuous food supplement, which leads to a large consumption of blood sugar in a short period of time, which makes the energy needed for brain cell metabolism insufficient, resulting in hypoxia symptoms, so dizziness occurs. Sweating a lot after strenuous exercise may also cause dizziness after exercise, because sweating a lot may also lead to insufficient blood volume, thus causing dizziness.
In addition, if you have anemia, poor sleep or other diseases, you may have dizziness and other symptoms after a lot of exercise, so you need to identify yourself.
It is suggested that you try to avoid long-term fasting exercise and strenuous exercise during normal exercise. After exercise, you must replenish glucose in time, such as drinking honey water, and replenish water in time, preferably drinking light salt water to replenish lost water and salt to avoid dizziness after exercise.
