Fitness is an activity that many young people like to do now, because it can increase the activity of the body, enhance the immunity of the body, make us have a better body shape, and play the role of losing excess body fat. However, fitness should be controlled at an appropriate level, and too intense may cause dizziness and vomiting.

Dizziness and vomiting during fitness are mostly caused by low blood sugar levels in the body. This is because there is not enough energy to supplement before fitness, and then carry out high-intensity activities. The common energy source of our body is glycogen, and fat is a kind of stored energy. Therefore, in order to achieve a good slimming effect in daily fitness, we need to consume fat, but this consumption should start from eating jiaozi, so we can't do high-intensity activities on an empty stomach, because it will make our stomach.

The blood supply of the stomach and intestines is affected, and the circulation of oxygen will affect the normal operation of our body. Because the stomach is on an empty stomach, the blood of the body will be more concentrated in the stomach. The two parts can't reach the brain in time, and then the blood sugar content in the blood is relatively low, so naturally there will be hypotension and hypoglycemia, because hypotension will lead to dizziness and even nausea and vomiting. This is because there is not enough jiaozi in the body for us to exercise, and then the burning of fat does not reach the effective burning range. Because fat burning needs more oxygen, but we don't have enough blood to transport oxygen.

Fitness is a very good activity, but we should also properly grasp the scale, especially for beginners, don't regard fitness as a hobby, it is not necessary to do it, and insist on going for a period of time every day is the best way to exercise. You can't say that you go once a week and practice yourself exhausted. This situation is unfavorable to our muscle development and the improvement of physical fitness.
