Dermatologists warn that extended wear can lead to skin irritation, rashes, and flare-ups of existing conditions. Tight or snug underwear traps sweat and heat, which can irritate sensitive skin and disrupt the body’s natural balance.
Experts explain that areas with limited airflow are especially prone to bacterial and fungal growth. When underwear isn’t changed daily, the risk of infections increases — including common conditions caused by yeast or bacterial imbalance.
It Affects Everyone
These hygiene risks aren’t limited to one gender. Men can develop fungal infections such as jock itch, which causes redness and itching in warm, moist areas. Even looser styles like boxers don’t eliminate the risk if they’re worn repeatedly without washing.
Health professionals emphasize that underwear acts as a barrier between the body and outer clothing. When that barrier isn’t clean, problems can develop quickly.
How Often Should You Change?
Doctors agree on a clear rule: underwear should be changed at least once every 24 hours. For people who sweat heavily, exercise frequently, or live in hot and humid climates, changing more than once a day may be necessary.
Experts also advise paying attention to early warning signs like itching, discomfort, or irritation. Switching to a clean pair right away and seeking medical advice if symptoms persist can help prevent more serious issues.
Clean habits may seem small, but they play a big role in overall health.
