Sleeping in the buff - especially during hot summer months - is actually more beneficial for both men and women. Underwear, particularly tight and non-absorbent ones, invite bacteria and yeast to breed and can do more harm to the body.

When a part of the body becomes sweaty, this area becomes an ideal breeding ground for bacteria, which can lead to skin irritation, chaffing and eventually, infection. 

So experts advise that it is better to sleep at night without underwear so the nether regions are able to "breathe" thus preventing infections, the Daily Mail reported.

Dr. Alyssa Dweck, a full-time practicing OB-GYN based in New York, added that sleeping while wearing tight and non-moisture wicking underwear is especially worse for menopausal women suffering hot flushes at night.

For people not used to, or who don't want to, sleep "commando" style they can opt for loose-fitting panties. "If there's ever a time to break out of the granny panties, this would be it," Dr. Dweck said.

Also, sleeping nude gives greater comfort, according to Elite Daily. Besides, Planned Parenthood ran a report saying there is no scientific correlation between not wearing underwear and infection.

It is said that the phrase "going commando" is rooted in the military, coined by soldiers who choose to ditch their underwear to "increase ventilation and reduce moisture."

While both men and women can benefit from sleeping in the buff, the male population benefit more from this habit. 

“Your nether regions need to be just the right temperature in order to optimize sperm production,” said Dr Brian Steixner of Institute for Men’s Health at Jersey Urology Group, who was quoted by the
Daily Mail.

Dr Steixner cautioned that tight briefs or boxers can make the groin area too warm and subsequently affect the quality of sperm cells produced. MIMS
