1, when your body feels tired, it means that you exercise too much.
Exercise consumes physical energy, so it is normal to feel tired after exercise, and it usually disappears in a few hours. But if your fatigue lasts for two or three days or even longer, it means that you exercise too much. At this time, you need to rest, stop exercising, and need to supplement more nutrition to make your body recover as soon as possible.
2. If the brain feels anoxic, it means that you have exercised excessively.
I remember a rock climbing competition organized by the company. At that time, I climbed up in one breath, about 600 meters. At that time, I felt very breathless and breathless. Obviously, my brain is deprived of oxygen. I opened my mouth and exhaled. My head was a little dull and I almost fainted. Later, I came to the clinic for examination. The doctor said that excessive exercise caused hypoxia in the brain.
Therefore, moderate exercise is necessary. When you feel that your body can't stand it, you should stop exercising, let your brain rest and let your heart rate recover.
3. If you feel dizzy and have a headache after exercise, it means you have exercised too much.
Many people will get dizzy and headache after exercise, mainly because of the change of blood pressure in the body. Therefore, people with weak constitution should choose appropriate exercise according to their own situation, and never show off their talents, which will only damage their health.
Some people even feel sick after exercise. First of all, you should rule out the problem of diet. If you happen to exercise, it is probably caused by excessive exercise and lack of oxygen.
Therefore, exercise also needs to be gradual, and you must not eat fat at once.
