How often should we change our sheets?
The general consensus is that we should all be changing our sheets – including duvet covers and pillow cases – once a week, argues Tierno. However Professor Val Curtis, from the London School of Hygiene & Tropical Medicine, tells HuffPost UK she doesn’t believe leaving your sheets on for a few extra weeks will lead to health problems.

But, doing so might not look or feel great: Prof Curtis advises people to change their bedding once a week for “aesthetic reasons”.
Should we wash our duvets, too?

We should be giving our duvet a six-monthly clean or – at the very least – washing it once a year, according to The Fine Bedding Company. Bacteria and bodily fluids build up in duvets over a short period of time, the company argues, with duvet covers and pyjamas merely acting as a “first line of defence” against sweat.

According to Philip Tierno, professor of microbiology and pathology at New York University, underwear isn t built to last. That would be highly unsanitary. Because, ultimately, it s the most staple of menswear staples: we wear a fresh pair every single day (we ll say that a little louder for the grim seats at the back), and there s a lot of rough and tumble dryer involved.
Ideally, your underwear should be replaced every single year at the very least, and as the first thing you put on each and every day (anyone who believes it to be socks should seek a psychiatric assessment stat), it pays to go for quality, breathable cottons that keep everything fresh and well-ventilated. We don t need to explain why this is important.
