5. May Support Intimate Health
For women, sleeping without underwear may improve airflow around the vaginal area and reduce prolonged moisture buildup.

This doesn’t mean sleeping naked prevents infections, but avoiding unnecessarily tight or damp underwear can help support everyday intimate comfort.
