It is better not to go swimming when you have a cold, not to mention the fact that when you swim, the water temperature is a stimulus to the skin of the organism, and if you are in good health, this stimulus can be used as an exercise to improve the ability of the human organism to adapt to the outside world. But in the case of a cold, it means that a pathogen has invaded the body, and at this time the body’s energy should be fully focused on expelling the pathogen that triggered the cold, which is also a pretty big project and consumes energy, so at this time try not to do anything else to consume the body’s immunity. At this time, you should better cooperate with the body to expel the pathogen, drink more water, rest more, and sleep when you can, why do many drugs for colds contain drugs that can sedate or promote sleep? Like white plus black, black tablets are to let you sleep well at night, the better you sleep, the better your body’s immunity recovers, and the faster you get over a cold.
