Body heat after exercise

Exercise is a common activity and has many benefits. For example, losing weight and building muscles can be achieved through exercise. However, many abnormal conditions will occur in the body after exercise, including fever. This can be a normal condition or an abnormal condition. So why does the body feel hot after exercise?

Normal physiological phenomenon.

After exercise, the body's anabolism and catabolism will accelerate, so you will get hot and sweat and your body temperature will rise. This is a very natural physiological phenomenon. Specifically, anabolism is the process of synthesizing protein and fat from the food we eat. Catabolism is the process of breaking down the food we eat into energy, and the process of catabolism produces heat. Especially after strenuous exercise, blood flow accelerates and local fat burns, which can lead to low fever and may cause discomfort symptoms such as fever, dizziness, chest tightness, etc.

The body feels uncomfortable because while sweating, some inorganic salts and a large amount of water in the body are lost along with heat. In addition, during exercise, oxygen is inevitably insufficient, causing the body to produce lactic acid through anaerobic respiration. The internal environment homeostasis fluctuates greatly. This is why you are very thirsty after exercise. At this time, it is recommended to drink more light salt water or soda water (to neutralize lactic acid).

Catching a cold and having a fever after exercise.

There is another situation in which fever occurs after exercise. It may be caused by catching a cold after exercise, especially when a person's immunity is relatively low after strenuous exercise. For example, if you don’t wipe off the sweat in time and are blown by the wind, or if you take a cold shower, etc. Some people exercise the day before but develop a fever the next day. This is mostly due to this.

However, a large part of the reason why sweating during exercise leads to catching a cold, fever, etc. is simply because you did not take good care of the sweating after exercise. After sweating during winter exercise, you must wipe off the sweat on your body in time and change into fresh clothes, so you are less likely to catch a cold. It would be better if you could take a hot bath after fitness exercises in winter, and also remember to soak your feet in hot water every night.
