Many people wear underwear every day without giving it much thought. However, some health experts say that occasionally going without underwear—especially while sleeping or when wearing loose clothing—may offer certain health and comfort benefits for both women and men. The key is maintaining good hygiene and choosing what works best for your body.
For women, not wearing underwear may improve airflow around the genital area. Better ventilation helps reduce moisture, creating an environment that is less favourable for yeast and certain bacteria to thrive. Women who are prone to recurrent yeast infections may find that allowing the area to stay dry and breathable can be helpful.
Another benefit is reduced irritation. Tight underwear, particularly those made from synthetic materials, can cause friction, redness, or discomfort. Going without underwear under loose-fitting clothing may reduce rubbing and improve comfort, especially during hot weather.
Women with sensitive skin may also notice fewer allergic reactions caused by dyes, elastic bands, or certain fabrics used in underwear.
For men, wearing no underwear—particularly at night—may improve comfort by reducing heat and moisture around the groin. Some studies suggest that keeping the testicles slightly cooler supports normal sperm production, although underwear is only one of several factors that can influence fertility.
Men may also experience less chafing when wearing loose trousers or shorts without tight-fitting underwear, particularly after long periods of sitting or during warm weather.
For both men and women, sleeping without underwear may improve comfort and help the skin breathe overnight. Many people report feeling cooler and more comfortable, especially in warmer climates.
However, going without underwear is not suitable for every situation. Wearing underwear can help absorb sweat, reduce friction from rough clothing, and provide an extra layer of hygiene when wearing jeans, work uniforms, or sportswear.
People who exercise regularly should also wear clean, moisture-wicking underwear during workouts to reduce skin irritation and maintain hygiene.
If you choose not to wear underwear, it is important to wear clean outer clothing and wash trousers, shorts, skirts, or pyjamas regularly. Good personal hygiene remains essential regardless of your choice.
There is no medical rule that says everyone should or should not wear underwear. The decision depends on comfort, health needs, clothing choices, and personal preference. If you experience persistent itching, unusual discharge, pain, or skin irritation, consult a healthcare professional, as these symptoms may indicate an underlying medical condition rather than being related to underwear.
Ultimately, whether you wear underwear every day or occasionally go without it, the most important factors are cleanliness, breathable clothing, and listening to what feels healthiest and most comfortable for your body.
