Here Are The Reasons Everybody Must Be Sleeping NAKED

Wearing underwear in bed can be bad for your health, according to recent research.

Sleeping in pants can cause bacteria to collect in the nether regions - and can be even more of a problem for those who sweat in their sleep.

The problem is believed to be worse for men than women as it could affect male fetility.

The findings come from gynaecologist Dr Alyssa Dweck, who works for several hospitals and health centres in New York state, who has just written on the subject.

She said: "I often tell my patients to sleep without underwear.

"If [the area] is constantly covered - especially by a fabric that’s not moisture-wicking or absorbent - moisture collects, creating the perfect breeding ground for bacteria or yeast."

Dr Dweck says this could lead to severe chafing, irritation and skin infections and that people who would rather not sleep in the buff should go for loose-fitting cotton pair.

She added: "If there’s ever a time to break out the granny panties, this would be it."

The problem can be a lot more serious for men according to Dr Brian Steixner - Director of the Institute for Men’s Health at Jersey Urology Group in the US.

Dr Steixner warned that men who sleep in boxers or briefs run the risk of affecting the quality of their sperm as their crotch can become too warm during the night.

He said: "Your nether regions need to be just the right temperature in order to optimise sperm production."

"More bacteria makes for a higher likelihood that any chafed or irritated skin down there becomes infected."

Sleeping in the nude can also help to cool down the body, which can aid in lowering blood pressure, according to Dr Dweck.

She said this can be helpful for women experiencing hot flushes due to menopause .
