Normal physiological phenomenon
After exercise, the anabolism and catabolism in the body will be accelerated, so it will cause fever, sweating and body temperature rise, which is a natural physiological phenomenon. Specifically, anabolism means eating, synthesizing protein and synthesizing fat. Catabolism is to re-dissolve what you eat into energy, and the process of catabolism will produce heat. Especially after strenuous exercise, blood flow is accelerated, and local fat burns, which will lead to low fever and easily cause discomfort such as fever, dizziness and chest tightness.
The body will feel uncomfortable, because some inorganic salts and a lot of water in the body will be lost with heat when sweating. In addition, when exercising, oxygen will inevitably be insufficient, leading to lactic acid produced by anaerobic respiration of the body, and the internal environment will fluctuate a little, which is also the reason for being very thirsty after exercise. At this time, it is recommended to drink more light salt water or soda water (to neutralize lactic acid).
Cold and fever after exercise.
There is also a fever after exercise, which may be caused by catching cold after exercise, especially after strenuous exercise. If you don't wipe your sweat in time and get blown by the wind, or take a cold shower, etc. Some people exercise on the first day and have a fever the next day.
However, the cause of cold and fever caused by exercise sweating is largely because you didn't do a good job in sweating care after exercise. After sweating in winter sports, you must dry your sweat in time and put on fresh clothes, which is unlikely to cause problems such as colds. It will be better to take a hot bath after winter fitness exercise, and pay attention to taking a hot foot every night.
