Almost a third of Brits only wash their bedsheets once a year, a survey has found.

Iran PressEurope: In research conducted by furniture company Hammonds, 30 percent of 2,000 British respondents said they only give their bedding an annual washing.

"In fact, you should wash your bed sheets about 52 times more regularly than that," Dr. Aragona Giuseppe, GP and Medical Advisor said.

He said: "Washing your clothing items and bedsheets regularly is important for overall cleanliness and ensuring your body remains clean and healthy.

"If you do not wash clothing items often you could be at risk of infection or just feeling and smelling unclean.

"Bedsheets and pillowcases should be washed as if they are dirty, this could promote acne, spots, and other skin issues due to the dirty bacteria on the sheets transferring to your skin."

Not washing your sheets frequently could also lead to more serious issues.

Dr. Oma Agbai told Women's Health: "Skin cells coming off your body on a daily basis and settling into your sheets can breed the growth of certain bacteria and certain mites."

So it seems like a third of you might be better off washing your bedding more than once a flippin' year.

You might want to wash them more regularly still if you're the sweaty sort, and it's for this same reason that one cleaning expert has advised against making your bed first thing in the morning.

Mrs. D, who is well known for her simple tips and tricks for keeping a house spick and span, urged us all to let our bedding 'breathe'.

In a post on Instagram, she said that over the course of a night, our hot and damp sheets attract bed bugs and dirt, and we should be keeping the covers off for some time after waking up.

She wrote: "It seems a lot of people get up and make the bed straight away. This is something you need to stop doing. During the night we not only sweat but also shed skin, and this is a magnet for dust mites and bed bugs. They love damp and humid areas, and some people only let their beds breathe in the summer, and think that you don't need to do this in the winter because of the cold weather. But this isn't true. With central heating being on in the winter it can attract dust mites/bed bugs just as much as in the summer months. So, by making your bed first thing every morning you are trapping all that damp air and helping dust mites/bed bugs breed (sounds horrible, but it's true)."

18 percent of Brits only wash jeans annually and 36 percent only wash blankets once in this period, according to stats released by Hammonds Furniture.

Just when you think there are saving graces - with 40 percent washing their towels after every use and 80 percent washing underwear after ever wear - more horrifying statistics rain down upon our us.

About 25 percent of men admitting to only washing their underwear after every five washes, and 10 percent of men claiming to only wash their underwear after every ten washes. Ten washes. Ten. Can you imagine? It doesn’t bear thinking about.
