Is it healthy to sleep naked?

Objectively speaking, sleeping naked is helpful to the development of the body, but in fact, sleeping naked is harmful to health. There are a lot of bacteria and mites on sheets and bedding. When sleeping, human dander and sweat stains will rub on the bed, causing bacteria to multiply and infect the human body. Therefore, I suggest not to sleep naked. You can sleep in loose and clean pajamas, just like sleeping naked.
