If you wake up with a stuffy nose, itchy eyes or sneezing fits, your bed is often the first place to look. If you have allergies, the clearest and most practical guideline is this: wash your fitted sheet, duvet cover and pillowcases once a week if possible, preferably at 60°C if the care label allows it. That reduces the build-up of dust mites, skin flakes, sweat and pollen in the fabric you spend hours in every night.
If your symptoms are only mild, you may also hear the advice to wash it once every 2 weeks. Still, changing your bedding weekly is usually the safest routine, especially if you have a dust mite allergy, sensitive airways or during pollen season. Below, you can see exactly what to wash and when, at what temperature, and which extra steps help to keep your bedding fresh.
The short answer: this is a practical washing schedule
Use this schedule as a simple starting point for changing bedding if you have allergies.
| What | How often to wash | Recommended temperature |
|---|---|---|
| Fitted sheet, duvet cover, pillowcases | Weekly | Preferably 60°C |
| Mattress cover or mattress protector | Every 4 to 6 weeks | According to the care label, preferably as warm as possible |
| Pillow and duvet | Every 6 to 8 weeks | According to the care label, preferably 60°C if possible |
| Throw, soft toy, decorative cushion in bed | Every 2 to 6 weeks or remove from the bed | According to the care label |
Not sure whether to wash weekly or every 2 weeks? If you have active symptoms, it is better to wash more often rather than put it off. The textiles closest to your face and skin usually make the biggest difference.
Why washing more often helps with allergies
A lot of triggers come together in bed: warmth, moisture, dust and skin flakes. That makes your bed a logical place for dust mite allergens, as well as pollen that you bring inside during the day. You do not need to be able to see dust mites to be affected by them. Symptoms are usually caused by the allergens left behind in dust and fabrics.

By washing your bedding regularly, you remove some of that load. Pillowcases and fitted sheets are especially important because they lie directly against your face and body. If you notice that you mainly sneeze, have a blocked nose or get irritated eyes in bed or when you get up, a stricter washing routine is a logical first step. It will not solve everything, but it often does help make your bed feel fresher and calmer.
What else should you wash besides your sheets?
Duvet and pillow
It is not only your cover that matters. Your pillow and duvet also absorb moisture, dust and skin flakes. If they can go in the washing machine and the label allows it, wash them about every 6 to 8 weeks. If your symptoms are severe or you sweat a lot, you can do this more often. Always let them dry completely afterwards so no moisture stays trapped inside.
Mattress cover and mattress protector
A mattress cover or mattress protector catches a lot, so it deserves attention too. A practical guideline is to wash it every 4 to 6 weeks, and more often if you sweat easily or react sensitively. If your symptoms stay stubborn, an allergen-proof cover around your mattress or pillow can be a useful extra barrier.
Everything that stays in bed
Soft toys, throws, extra blankets and decorative cushions also collect dust and allergens. Only keep in bed what you really use and wash washable items regularly along with the rest. The fewer loose textiles in and around your bed, the easier it becomes to keep your bedroom fresh.
At what temperature should you wash bedding if you have allergies?
For allergies, 60°C is usually recommended for bedding that comes into direct contact with your skin. That temperature helps get bed linen thoroughly clean. Always check the care label, because not every material can be washed that warm if you want to wash your bedding properly.
Can a fabric not handle 60°C? Then wash it at the highest permitted temperature and make up for it with a smart routine: change it more often, let it dry well, and keep your bedroom dry and low in dust. Do not overfill the washing machine either. Bedding needs room to get truly clean and to feel fresh and soft again afterwards.
How to make your bedroom less friendly to allergens
Washing works best in combination with a few calm habits in the bedroom:
- Air out the bedroom daily and leave your bed open for a while after getting up.
- Avoid a clammy sleep climate and keep humidity on the low side.
- Vacuum regularly and wipe smooth surfaces with a damp cloth.
- Limit heavy curtains, loose throws and other dust catchers around the bed.
- During pollen season, try not to get into bed in the clothes you wore outside, and rinse or brush your hair before going to sleep if you have been outdoors a lot.
If hay fever is your main issue, pollen may play a bigger role than dust mites. Even then, weekly washing remains wise, especially for your pillowcase and duvet cover. That way, your bed not only feels cleaner, but often calmer too when you deal with allergies and skin irritation caused by bedding.
What bedding feels comfortable if you are sensitive to allergens?
Do not let terms like hypoallergenic bedding be your only guide. More important are the qualities that genuinely help in daily use: a fabric that feels pleasant, breathes well, is easy to care for and can be washed often according to the label. If you want to understand the term itself, see what hypoallergenic really means. Think of materials such as cotton, Tencel or easy-care microfibre, depending on what you like in terms of feel and sleep climate.
Ideally, choose bedding that feels soft against your skin and does not feel heavy or clammy after a night's sleep. That fresh, dry feeling is exactly what makes it easier to stick to a regular washing routine. Comfort and practical care go hand in hand here.
When extra measures make sense
Do your symptoms keep coming back despite regular washing, airing out and cleaning? Then you can consider extra protection for your mattress and pillow. Allergen-proof covers are often used for suspected or diagnosed dust mite allergy. They do not remove the cause, but they can help limit exposure.
If you keep dealing with a blocked nose, lots of sneezing or shortness of breath for a longer period, discuss it with your GP. Especially if your symptoms return every morning, it is useful to know whether allergy really is the main cause.
Frequently asked questions about washing bedding for allergies
How often should you wash bedding if you have a dust mite allergy?
For fitted sheets, duvet covers and pillowcases, once a week is the most practical guideline if you have a dust mite allergy. If your symptoms are mild, you may sometimes hear once every 2 weeks, but weekly usually gives you more control.
How do you know if you have dust mites in your bed?
You usually cannot see dust mites themselves with the naked eye. One sign can be that you mainly have symptoms in bed or when you get up, such as sneezing, a blocked nose, itchy eyes or a tickle in your throat. That does not prove it, but it does make your bedroom a logical place to tackle first.
What bedding is suitable for people with a dust mite allergy?
Choose bedding that you can wash regularly, that dries quickly and breathes well. So focus mainly on washability and ease of care, not only on a marketing label. A smooth, comfortable fabric that is easy to keep clean is often the best choice.
Do you also need to wash your duvet and pillow?
Yes, if the label allows it. Wash them about every 6 to 8 weeks and let them dry well. If they are not washable or your symptoms remain stubborn, a protective cover can be a useful addition.
Is washing alone enough to help with allergies?
Washing often helps, but a combination usually works better: change bedding weekly, wash it in time, air out the room, reduce dust and avoid too many textiles around your bed. So see washing as the foundation, not the only step.
So choose bedding that feels soft, breathes well and is practical to wash. That way, a fresh bed is not something just for the weekend, but simply a realistic part of your sleep routine.
