Survey on British laundry habits
Some sheets rarely washed
Older people have cleaner sheets
A UK study has shown half a million Brits only wash their sheets three times a year, mX reported.
One in six people also owned up to waiting at least four weeks before washing their bed sheets. Londoners are the worst culprits with a quarter of those polled leaving it at least a month before washing their bed linen, the insurance firm survey found.

Under-25s tended to have the dirtiest sheets, with one in 10 admitting to washing theirs only six times a year, and half of all people surveyed admitted to eating in bed.

Houseproud over-55s aired their dirty laundry on average three times a month.

"It's estimated that 10 per cent of the weight of a two-year-old pillow is comprised of dead skin and dust mites," said expert Dr Lisa Ackerley.

"So it's no surprise that your bed can become a minefield of bacteria, viruses, sweat and hair which can cause or exacerbate asthma.
"You need to wash your bed linen at least once a fortnight, and preferably once a week."
