According to a new survey by a British store called Dunelm Mill, nearly one in five people change their sheets only once a month, or less.

Here's how often people wash the sheets on their bed:  

#1.)  Two in five people wash their sheets every week . . . and MEN are slightly more likely than women to wash them that often.

#2.)  One in three change their sheets every two weeks. 

#3.)  A little less than one in five . . . 17% . . . do it every month, or even LESS frequently.

#4.)  6% of us wash them MORE than once a week.

#5.)  And 1% of us only wash our sheets ONCE a YEAR.
