WHEN it comes to matters of the bedroom, most people would assume that men are "dirtier" between the sheets than women.

But according to a new study, the opposite now appears to be true..

New research into how often men and women respectively clean their sheets has found that us ladies are lagging behind in this department.

Okay so admittedly, when we say "dirty" we mean it in the most technical sense of the word.

Out of the 2,000 people ErgoFlex surveyed, researchers discovered that millennial men are religiously washing their bed sheets every two weeks.

Meanwhile, us ladies can only be bothered to change our bedding once every month. Which is kind of gross when you think about it.

And to our surprise, 61 per cent of women also said they prefer sleeping naked compared to just 39 per cent of male participants.

As for those who favour PJs, men also stormed ahead in how often they were washing their sleepwear.

While pyjama-wearing women said they puts theirs through the wash once every five wears, men opted for every three. Seriously, who would have thought it?

Commenting on the surprising findings, a spokesperson for ErgoFlex said: "We found it interesting that men seem to be far more hygienic when it comes to their bed than females do, especially when compared to old data."

And even though changing your bed sheets can be a total drag, the experts at ErgoFlex recommend swapping your bedding "at least once every couple of weeks, especially if it's hot, but once a week is preferable."

Looks like it's going to be a laundry heavy weekend...
