Health experts say wearing underwear to bed can cause unexpected problems ranging from infections to poor sleep. The advice may surprise many, but the risks are real.

The team at Belle Lingerie explains that underwear traps warmth and moisture, creating the perfect environment for yeast and bacteria. “It’s recommended to allow this area to air out overnight,” they advised. Women face higher chances of UTIs, while men may see reduced sperm count.

Skin irritation is another danger. Tight fabrics rub against the skin, leading to rashes, redness, and fungal infections. Experts add that “our skin regenerates at night, but it needs proper ventilation.” Without airflow, bacteria and sweat can cause odors, blocked pores, and even acne-like breakouts.

Comfort matters too. Twisted or tight underwear may disrupt sleep, leaving people tired and unfocused the next day. Synthetic fabrics can also release chemicals that may affect hormone balance over time.

Doctors suggest the simplest fix: sleep nude or wear light cotton pajamas. Would you consider ditching underwear at night for better health?
