What are the dirtiest places in your bedroom?

We all know the bedroom should be a place to relax, recharge, and get a good night’s sleep. But considering we spend a whopping 27 years of our lives in bed (plus another seven just trying to drift off), it’s fair to say we spend a lot of time in this one room.

The problem? All that time makes our bedrooms a prime breeding ground for bacteria, especially in spots we don’t always think to clean. To uncover the worst offenders, Martin Seeley, Senior Sleep Expert at MattressNextDay, has shared the surprising dirtiest places in the bedroom, and his tips for tackling them.

 

1. Your mattress

A mattress works harder than just about anything else in the house, but unlike shower trays or kitchen utensils, they’re often forgotten when it comes to cleaning.

“Recent studies have shown that the average mattress contains up to 10,000 dust mites. Practically invisible to the naked eye, dust mites feast on the dead skin we shed and flourish in warm, moist conditions. It probably won’t shock you then to learn that your mattress is one of the main places that dust mites like to live. It’s warm, cosy, and constantly fed with the fluid and dead skin that we lose at night.

“These dust mites can then produce more than 2 million droppings, which are known to aggravate allergies. In many cases, it’s the enzymes released in dust mite droppings that cause or inflame certain allergic reactions, particularly asthma or other associated breathing problems.”

Most manufacturers suggest a good clean at least twice a year, though Martin recommends a seasonal refresh every three months, especially if you’re flipping or rotating your mattress anyway.

How to clean your mattress

• First, air it out. Turn back the covers in the morning and let the mattress breathe for at least half an hour on bedding change day.
• Then, hoover it. This will get any loose dirt and debris off the surface.
• Spot clean any stains using a damp cloth and a mild detergent, like washing up liquid. Don’t soak the mattress, just blot the stain until it comes out.
• Finally, mix distilled white vinegar with water and a few drops of essential oil (lavender for relaxation or tea tree for its bug-repelling powers). Spray lightly across the mattress surface to keep it fresh.

When it comes to your bedding, make sure you remove any yellow stains when washing, dry thoroughly and then make up your bed.

 

2. Light switches, lamps and fan controls

Think of how many times you touch your light switch each day, then think about how often you actually clean it. According to a recent survey, one in five Brits admit they only tackle light switches once a year (or less).

“Light switches are one of the first things we touch in the morning and one of the last things we touch before we go to sleep. Despite light switches being a key part of our bedroom routines, they’re often not cleaned regularly, if at all, meaning they can harbour skin bacteria like Staphylococcus and Streptococcus and even E. coli if hand hygiene is neglected.

“Bedside lamp touchpoints can be even more overlooked than wall light switches, particularly if the switch is hidden on a long lead or tucked under the rim of the lampshade. And for those who like to fall asleep with a cool breeze, this goes for fan controls too.”

A simple wipe-down with mild disinfectant spray can make a huge difference, keeping those high-touch surfaces safe and clean.

 

3. Headboards

One in three of us admit to never cleaning our headboard, which is worrying given how close it is to where we sleep. Upholstered or fabric headboards are the worst culprits, trapping dust, oils, and even mould.

“Many of us are guilty of sitting in bed with wet hair wrapped in a towel after a shower, but what you might not realise is that this can encourage mould growth over time, particularly on fabric, upholstered or wooden headboards. These mould spores can then worsen allergies and breathing difficulties, making it harder to get a good night’s sleep.

“Not only this, but headboards are a common hiding spot for bed bugs, which typically lurk in warm, soft spaces like upholstered or fabric headboards.”

The fix? Wipe down solid headboards with a mild disinfectant, and hoover fabric versions regularly to cut down on dust, mould, and unwelcome visitors.

 

4. Blankets and throws

As the nights draw in, it’s tempting to pile on extra blankets and throws. But while most people keep on top of duvet hygiene, these added layers are often overlooked, with 36% of Brits confessing they wash their blankets just once a year.

“Just like duvets, sheets and pillowcases, blankets and throws absorb our sweat, dead skin cells and body oils throughout the night, making them the ideal habitat for bacteria and dust mites to build up.

“Because blankets and throws are often kept close to our faces during sleep, they can trigger allergies and breathing issues if they aren’t washed regularly, leaving you tossing and turning through the night instead of getting proper rest.”

The solution is simple: pop them in the wash weekly along with your bedding. Your sleep will thank you.

You might also want to consider a washable duvet. We have one for the summer and I wouldn’t be without it. Simply put it in the washing machine and wash it like you would your bedding. It can even go in the tumble dryer.

 

5. Hot water bottle covers

A hot water bottle can be a cosy (and budget-friendly) alternative to switching on the heating. But while we refill the bottle often, the covers themselves are rarely washed, if at all.

“As the evenings get colder, hot water bottles will be making a welcome return to our bedtime routines across the nation. And while they’re refilled regularly, the fabric covers and the bacteria they can harbour are rarely given a second thought. In fact, most of us have probably never washed our hot water bottle cover.”

Luckily, most covers can go straight into the wash with your bedding. For fleece, fur, or knitted versions, a gentle cycle at 30°C with mild detergent usually does the trick.

 

Your bedroom should be the cleanest, cosiest space in your home – but it’s easy to forget the little things. From mattresses and headboards to light switches and blankets, these everyday items can harbour a surprising amount of bacteria. A few extra minutes of cleaning each week could be the difference between a restless night and truly restorative sleep.
