I have a deep understanding of this, in fact, it is very simple, because you have never exercised before and your life is very regular; Sudden sports will break the rhythm and laws of your previous life, and you will definitely feel uncomfortable physically. This directly led to endocrine disorders, so there is your current situation.

There are many people in the gym, so it is dirty; Generally, don't treat your face with your hands after exercise to prevent bacterial infection. There are towels or something, so you'd better get them ready. Don't leave them anywhere. It's best to use dry towels instead of wet towels.

You will sweat a lot after exercise, so don't wash your face immediately, because at that time, your skin is radiating and your pores are opening. Washing your face immediately will also lead to bacteria entering your face.

That's all. I hope you can have a look. It will help you.
