Research has shown the public cannot agree on the answer, and a new survey of 2,250 UK adults has found another split.
Almost half of single men said they don’t wash their bed sheets for up to four months at a time, with 12% admitting they wash them when they remember - which could be even longer.
Single women changed more often, 62% cleaning their bedding every two weeks, and couples claiming to do theirs every three weeks, according to data from a bedding company.
To cut to the chase, Dr Lindsay Browning, a chartered psychologist, neuroscientist and sleep expert, says we should be changing our sheets once a week, or every two weeks at the most.
Hygiene is a big factor, and one of the reasons is sweat. If you’ve ever tried sleeping in a heatwave, you’ll know how difficult it can be.
But it’s not just sweat that we need to think of, our own dead skin cells which we get rid of during sleep are also a concern.
Sound horrible? It gets worse. That build-up means small creatures known as mites can feed off those cells, causing discomfort and skin rashes.
If you’re going more than every two weeks “you’re getting into not so great territory”.
Forgetting (67%), not being bothered (35%), and not having any other clean bedding (22%) are some of the top reasons people say they don’t change their bedding more, with 38% saying they didn’t believe bedding needed washing “more often”, according to the Pizuna Linens research.
Dr Browning says “if your sheets are not washed, and they look dirty, they smell, it’s adding to that sensation that your bed isn’t somewhere that you want to be”.
Yuk … not washed for “months at a time” …
Their beds must be crawling with bugs …
