Many people say that running has a good influence on our health. Most importantly, running can strengthen our physique and help some people with poor immunity. For example, staying indoors is definitely more likely to catch a cold than people who stay outdoors all the time, so running is generally carried out outdoors, because you can breathe good fresh air and the chance of getting infected with the virus is very small, so running can effectively prevent colds.

Although running can prevent colds, you can't run a lot. If you run a lot, you may increase the chance of catching a cold. After a lot of running, our body's immunity and system will temporarily decline. During this period, viruses, microorganisms and other harmful substances will flood in, thus increasing our chances of getting sick.

When running, you must add or subtract clothes according to the change of weather. Be sure to remember not to wear too thick clothes when running, so as not to take off your clothes at will when you feel hot, and then a cold will definitely cause it, so wear clothes properly when running.

Running and fitness can improve our muscle strength, and your physical fitness will also be greatly improved. If you persist in running for a long time, your immunity will be high. In this case, no matter how big the flu is, you won't catch a cold. Therefore, running is really helpful to our health.
