You lie in your bed for about eight hours every night. That's 56 hours a week on the same sheets. During all that time, your body is shedding dead skin, producing sweat and leaking oils into the fabric. Dust mites love that stuff. They feed on it. Bacteria multiply in it. And if your dog or cat sleeps on the bed too? Add fur, dander and whatever they've dragged in from the garden. So how often should you wash bedding? More often than most people think. This guide goes through every type of bedding, the right wash frequency for each and the best way to do it without damaging anything.
What Builds Up in Bedding You Don't Wash Regularly?
Most people sweat about 200ml every night. In one week, that's over a litre of moisture your bed sheets have absorbed. Your pillow absorbs even more because your face and head press into it for hours. That warm, damp environment is perfect for dust mites.
Dust mites don't bite. But their droppings trigger allergies and asthma. Waking up with a blocked nose, itchy eyes or sneezing fits? Your bedding could be doing that. Bacteria from skin and saliva build up on pillowcases too. That contributes to acne breakouts, especially on your face and jawline. Fungal spores also grow in damp, unwashed fabric. None of this is visible. You can't smell most of it either. But it's there. And the only way to deal with it is regular washing.
The Wash Schedule for Every Type of Bedding
Not everything needs washing on the same day. Some things want weekly attention. Others can wait a few months. Here's the clear answer to how often should you wash bedding for each item:
Bed sheets and pillowcases: every single week, no exceptions
Duvet covers: every two weeks. Weekly if you sweat a lot or have allergies
Pillows themselves, not just the cases: every three months
Duvets and comforters: every three to four months. Twice a year at absolute minimum
Mattress protectors: once a month
Blankets and throws on the bed: every two to four weeks depending on use
Been ill? Don't wait for the schedule. Strip the bed and wash everything that day at 60°C. Same goes for heatwave nights when you've sweated through the sheets. Our bedding care guide covers more specific situations.
Wash Settings for Different Bedding Materials
Each bedding material has quirks. Cotton acts different from silk. Down duvets need different handling from synthetic ones. Get the settings wrong and things shrink, clump or fall apart.
Bedding | Temperature | Cycle | How to Dry |
|---|---|---|---|
Cotton sheets | 60°C | Normal | Tumble medium or line dry |
Linen sheets | 40°C | Gentle | Air dry. Iron while still a bit damp |
Silk pillowcases | 30°C or hand wash | Delicate | Air dry flat. Keep out of direct sun |
Polyester sheets | 40°C | Normal | Tumble low or air dry |
Down duvets | 40 to 60°C | Gentle | Tumble low with tennis balls |
Synthetic duvets | 40°C | Normal | Tumble medium |
Memory foam pillows | Don't machine wash | Spot clean only | Air out in sunshine monthly |
40°C | Gentle | Tumble low with tennis balls |
Cotton sheets at 60°C hits the sweet spot. Hot enough to kill dust mites. Safe enough for the fabric. If anyone in your home has allergies, always wash at 60°C or higher. Cooler water cleans the surface but won't reliably kill mites.
Red Flags That Say "Wash Your Bedding Now"
Even with a schedule, sometimes your bedding needs attention earlier. Watch for these:
You wake up sneezing, congested or with itchy eyes for no obvious reason
More breakouts than normal on your face, neck or back
Sheets feel oily or have a yellowish tint from body oils
You can smell something off when you get close to the pillow
Visible marks from sweat, drool or spilled drinks
Your pet has been sleeping on the bed recently
Someone in the house had a cold, flu or stomach bug
Any of those? Strip it all and wash it that day. Don't wait for the regular schedule.
Keeping Bedding Fresher Between Wash Days
You can't wash your bed sheets every single day. But these small habits stretch the freshness between washes:
Do This | Why It Works |
|---|---|
Air the bed 10 to 15 minutes every morning before making it | Moisture evaporates. Dust mites hate dry conditions |
Shower at night instead of morning | Less sweat, dirt and oil transfers onto the sheets |
Use a mattress protector and wash it monthly | Barrier between you and the mattress catches what leaks through |
Keep pets off the bed during the day | Less fur, dander and outdoor muck on your bedding |
Open a window for 15 minutes each day | Fresh air cuts moisture buildup in the room |
Rotate between two sheet sets | Each set gets more breathing time between washes |
These won't replace regular washing. But they make a real difference in how your bed feels through the week.
Can Dirty Bedding Really Cause Skin Problems?
Absolutely. It's more common than people realise. Pillowcases pick up bacteria, dead skin and hair product residue night after night. If you're prone to acne, a dirty pillowcase makes it measurably worse. Some dermatologists say change your pillowcase every two to three days if you have acne prone skin.
Beyond spots, unwashed bedding triggers eczema flares and general irritation. The mix of dust mites, sweat residue and bacteria creates conditions that aggravate sensitive skin. Tried every skincare product without results? Your bedding hygiene might be the thing you've missed. A fresh pillowcase can do more for your face than an expensive cream.
When Your Home Machine Can't Handle the Job
Sheets and pillowcases? Easy to wash at home. But have you tried fitting a king size duvet in a standard drum? It doesn't work properly. The duvet gets crammed in so tight that water and detergent can't circulate through it. Comes out half clean and takes days to dry.
At Nearest Laundry, we clean all types of bedding professionally. Duvets, feather pillows, mattress protectors, bedspreads and blankets. Each item gets the right method for its material. Free pickup and delivery across London within 24 hours. Our guide on how to wash a duvet explains the process in detail.
Wrapping Up
How often should you wash bedding? Sheets and pillowcases weekly at 60°C. Duvet covers fortnightly. Duvets and pillows every few months. Between washes, air your bed each morning and shower before sleep. Watch for signs like stuffiness and breakouts that tell you to wash sooner.
For heavy items that don't fit in your machine, Nearest Laundry handles it all. Free pickup and delivery across London. Check our laundry pricing and get your bedding properly cleaned.
