Sleeping without underwear: good idea or not?

Sleeping without underwear: good idea or not?

25 March 2025

You may not have thought about it, but sleeping with or without underwear is a conscious choice for many people. Some swear by it for its comfort and skin benefits, while others feel more comfortable with an extra layer of protection. But what does science say, and is it good to sleep without underwear? Time to take stock of the facts.

Why would you sleep without underwear?

Many people find that sleeping without underwear is simply more comfortable. No tight elastics, no seams that dig into your skin, and no fabric that chafes when you turn over. Especially if you normally wear tighter boxers, sleeping without underwear can feel liberating. It also provides better ventilation. Your skin gets more air, which means less heat and moisture build up. This not only helps against excessive sweating, but can also contribute to healthier skin.

Less friction is another benefit. If you have sensitive skin, the chafing of fabric can cause irritation. By not wearing underwear, you avoid that constant friction, which means less chance of red marks or a tight feeling when you wake up. Interestingly, research suggests that sleeping without underwear can also have a positive effect on male fertility.

Is it good to sleep without underwear? Well, it depends

If you prefer to sleep in underwear, it’s important to choose a breathable and comfortable fabric. Cotton is a good option because it allows air to pass through and absorbs moisture, while bamboo and microfiber are better at wicking moisture and feel extra soft. Silk feels luxurious and smooth, but it’s less effective at regulating moisture. Avoid synthetic fabrics like polyester or nylon, which trap heat and aren’t as breathable. Whatever you choose, make sure your underwear isn’t too tight and doesn’t have pinching elastics or chafing seams.
