Men who love to sleep naked are more powerful in bed

Sleeping naked reduces the temperature of the testicles

People who often have cold hands and feet may try sleeping naked once, and they will feel warm and comfortable, falling asleep quickly. Researchers point out that sleeping naked is like soaking in a hot spring; after removing clothing, the blood flow to the skin increases, and the heat produced by the body naturally dissipates, surrounding the body and enhancing its self-protection ability.

This kind of "unrestricted" state also helps improve chronic constipation, chronic diarrhea, and problems such as lower back pain and headaches. Some women's menstrual cramps and neck and shoulder pain issues will also gradually ease.

Sleeping naked is very popular in Japan.
