Perineum sunning
Complementary & alternative
Perineum sunning or butthole sunning is a wellness practice that involves exposing the perineum to sunlight. Adherents claim various health benefits such as improved libido, circulation, sleep, and longevity. There is no scientific evidence that this behavior promotes any of the alleged benefits. The practice of exposing a sensitive area of skin to sunlight also increases the risk of skin cancers. Safer alternatives such as mindfulness practices can achieve similar benefits.
