Precautions:

When people get up on an empty stomach, especially in the morning, their blood sugar concentration is low. If they start exercising at this time, they will consume a lot of energy and lower their blood sugar concentration. Especially for diabetics, it is necessary to avoid fasting exercise. Blood sugar is the direct energy substance of the brain. If the blood sugar concentration is too low, the brain will send a signal of fatigue because of lack of energy, and people will feel dizzy and weak, with pale face and cold sweat. If you continue to exercise, it may lead to unconsciousness and even coma. ?
