Not only can you exercise your heart and lung function well, but you can also have endurance and cold resistance.
A big step forward.
If you are just starting, I suggest you walk as slowly as possible after running.
Put it indoors, because we are not majoring in track and field and have just finished running.
You will sweat a lot and your pores will open all over your body, especially when the cold wind blows on your body in winter.
Cause wind-heat cold, I suggest you run home non-stop and do it at home.
Relax and walk slowly. You can take a bath after the sweat falls, so you won't catch a cold.
Anyway, my friend, we should pay attention to the cold weather in winter, as if we are not professional athletes after all.
It is easy to catch a cold in winter, pay attention to your health!
