For women, sleeping without underwear can lower the risk of yeast infections, while men may benefit from improved sperm quality by regulating testicular temperature. Sleeping naked also promotes better skin health, reduces stress and anxiety, and may help prevent weight gain.

While it may take some time to adjust, sleeping without tight clothing could ultimately contribute to better overall health and well-being.
