The belt needs to be worn through clothes. Some of the components of the belt are rough, and for some people with fragile skin tissue, it is easy to get hurt if they are used directly next to their bodies. If the belt is inferior, it will be worn close to the skin for a long time, and rubbing the skin will easily cause inflammation.

The main function of the belt is to fix the waist, relieve pain, keep warm, improve blood circulation and enhance the body's disease resistance. These functions can be played out more effectively through the use of clothes.
