When you sleep at night, can you tie a belt around your body to slim your waist? Is it harmful to your health?
You can slim your waist, but at night, your body needs to rest. It takes two days to ensure smooth blood circulation. Wearing a belt at night will only transfer fat to other places. So it is recommended not to do that. If you want to lose weight, you can wrap the waist with plastic wrap for waist exercise.
