Understanding how often you should wash your bedding isn't just about cleanliness—it's about creating the healthiest possible sleep environment, whether you're using traditional cotton or modern brushed microfiber duvet cover sets that make maintenance considerably easier.

Would you wear the same jumper for three weeks straight? Absolutely not. Yet many of us sleep on sheets that haven't been washed in weeks—or even months. We spend roughly a third of our lives in bed, shedding skin cells, sweating, and transferring oils from our bodies onto our bedding night after night.

Think about it: your bed is essentially a warm, moist environment—the perfect breeding ground for bacteria, dust mites, and allergens. Each night, you shed approximately 30,000 to 40,000 skin cells every minute, totalling around 200 million skin cells every hour, and produce between 500 and 700 millilitres (about 16 to 24 ounces) of sweat under normal conditions. This combination creates an invisible ecosystem within your bedding that can affect everything from your skin health to your sleep quality. 

In this comprehensive guide, we'll break down exactly how often you should wash your bedding—every component from sheets and pillowcases to duvets and the pillows themselves. Our recommendations aren't just arbitrary numbers; they're backed by dermatologists, allergists, and sleep experts who understand the hidden impacts of your bedding hygiene routine.

You'll discover why that stubborn acne might be linked to your pillowcase, how dust mites in your mattress could be triggering your morning sneezes, and why establishing the right bedding washing schedule might be the sleep quality upgrade you've been searching for.

Sheets: The Frontline of Sleep Hygiene

Q: How Often Should You Wash Your Sheets?

The short answer: Every 1-2 weeks—but your bedding washing routine should be tailored to your specific needs.

But why this frequency? Your sheets are the first line of defence in your bedding ecosystem, and they absorb the most direct contact with your body. Each night, they collect:

• Thousands of dead skin cells (humans shed approximately 30,000 to 40,000 cells every minute during sleep)

• Body oils that transfer from your skin

• Sweat (even if you don't feel sweaty)

• Saliva and drool

• Residue from lotions and products on your skin

• Environmental debris like pollen and dust

Dermatologists recommend washing sheets weekly for people with sensitive skin or acne-prone skin. Dr. Joshua Zeichner, Director of Cosmetic and Clinical Research at Mount Sinai Hospital, explains: "Oils and dirt from our skin and hair accumulate on sheets and can lead to skin irritation and breakouts."

For allergy sufferers, the stakes are even higher. Dust mites—microscopic creatures that feed on dead skin cells—thrive in bedding and can trigger respiratory symptoms. Regular washing in hot water eliminates these allergens and can significantly reduce night-time symptoms.

Can You Wash Bed Sheets Too Often?

Whilst cleanliness is important, there is such a thing as washing sheets too frequently. Very frequent washing (more than twice weekly) can prematurely wear out some fabrics, particularly natural fibres like Egyptian cotton or linen. However, premium brushed microfiber fitted sheets like those from Pamposh are engineered to withstand much more frequent washing without deteriorating.

The sweet spot for most people is weekly washing, though you might stretch to every two weeks if you:

• Shower before bed consistently

• Don't sleep in your birthday suit

• Don't have pets in your bed

• Don't have allergies or skin issues

For hot sleepers, those in humid climates, or during summer months, weekly washing becomes more important to prevent bacterial growth accelerated by moisture. This is where having the right bedding material makes a significant difference—fabrics that dry quickly and resist bacterial build-up can make maintaining your ideal washing schedule much more manageable.

Pillowcases: Where Your Face Spends 8 Hours a Night

The Surprising Case for Washing Pillowcases Twice a Week

Your pillowcase deserves special attention in your washing rotation—and for good reason. This fabric cradles your face for hours each night, making direct contact with your skin and hair. Consider what accumulates on your pillowcase nightly:

• Facial oils

• Makeup residue (even after cleansing)

• Hair products like serums, oils, and styling products

• Saliva

• Bacteria from your mouth and face

Dermatologists often recommend changing pillowcases twice weekly, especially for acne-prone individuals. "Your pillowcase can harbour bacteria and reintroduce it to your skin each night," explains Dr. Melissa Kanchanapoomi Levin, board-certified dermatologist and founder of Entière Dermatology.

This becomes even more important if you:

• Have oily skin or hair

• Use multiple skincare products before bed

• Experience regular breakouts

• Apply hair products daily

For those battling persistent acne, especially along the cheeks and jawline, try this experiment: wash your pillowcase every two days for two weeks and note any changes in your skin. Many patients report significant improvement with this simple adjustment.

Should You Wash Pillowcases More Often Than Sheets?

Yes, ideally! Whilst your entire body contacts your sheets, your face—with its more sensitive skin and proximity to your eyes, nose, and mouth—deserves extra protection. Pillowcases can be easily removed and added to smaller laundry loads between full bedding washes, making this high-impact habit relatively convenient.

Duvet Covers: Protecting the Core, But Not Immune

How Often Should You Wash a Duvet Cover?

The general rule: Every 2-4 weeks!

Your duvet cover acts as a protective barrier for your comforter or duvet insert, but it still collects its share of body oils, dead skin cells, and environmental debris. How often you need to wash your duvet cover depends largely on your sleeping habits:

• If you use a top sheet that stays in place: Every 3-4 weeks is typically sufficient

• If you sleep directly under the duvet cover (no top sheet): Every 2 weeks is recommended

• If pets sleep on your bed: Weekly washing becomes important

• If you eat in bed: More frequent washing may be necessary

Like sheets, duvet covers in contact with your skin should be washed regularly, though slightly less frequently since they typically have less direct body contact than sheets and pillowcases.

Should You Wash a Duvet Cover More Often in Summer?

Absolutely. Warmer weather means more sweat, which creates more moisture in your bedding. This additional moisture accelerates bacterial growth and can make your bedding smell musty more quickly.

During summer months or in warmer climates, consider washing your duvet cover every 1-2 weeks, especially if you don't use air conditioning or if you're a naturally hot sleeper. Not only will this keep your bedding fresher, but it can also help prevent heat rash and folliculitis that can flare when skin is in contact with sweat-soaked fabric.

Duvets & Comforters: Clean the Core, But Carefully

When & How to Wash Duvets and Comforters

General rule: Every 3-6 months.

Your duvet insert or comforter requires less frequent washing than its cover, but it still needs regular cleaning to prevent build-up of dust mites, skin cells, and other allergens that penetrate the cover over time.

The washing frequency depends on several factors:

• Down duvets: Every 6 months is typically sufficient if protected by a cover

• Synthetic duvets: Every 3-4 months, as they tend to trap more moisture

• If you use a duvet cover: You can extend washing to every 6 months

• If you have allergies: Consider washing every 2-3 months

How you wash your duvet matters significantly for its longevity:

For down/feather duvets:

• Use a front-loading machine without an agitator

• Select the gentle cycle with mild detergent

• Run an extra rinse cycle to remove all soap

• Dry thoroughly on low heat with tennis balls to prevent clumping

For synthetic duvets:

• These can typically withstand standard washing

• Still use gentle cycle when possible

• Dry completely to prevent mildew

Can You Wash a Duvet in a Washing Machine?

Yes, but with caveats. Most home washers can handle lightweight to medium duvets, but king-size or extra-thick duvets may require a commercial-size machine at a laundrette. The biggest concern isn't necessarily the washing but ensuring complete drying, as damp interiors can develop mould.

Can You Dry Clean a Duvet?

Absolutely. Dry cleaning is an excellent option for down duvets or those with delicate materials. Professional cleaners have the equipment to clean these bulky items thoroughly without damaging the filling. It's worth the investment 1-2 times yearly, especially for expensive duvets.

If you're looking for bedding that doesn't require such specialised care, Pamposh's brushed microfiber duvets can typically be washed at home with excellent results, saving you frequent trips to the dry cleaner whilst still maintaining impeccable hygiene.

Pillows: Your Sleep Support System (and Germ Magnet)

How Often Should You Wash Your Pillows?

Recommended frequency: Every 4-6 months

Whilst your pillowcase provides the first line of defence, your actual pillow still needs regular washing. Over time, pillows accumulate:

• Skin cells that penetrate the pillowcase

• Dust mites and their waste

• Oils from your hair and skin

• Moisture from sweat and drool

• Allergens from the environment

This invisible buildup can significantly impact both the cleanliness of your sleeping environment and the support your pillow provides. According to research, after just two years, approximately 10% of a pillow's weight can consist of dead dust mites, their droppings, and accumulated dead skin cells—a staggering fact that highlights the importance of regular pillow maintenance.

Different pillow materials require different care:

• Memory foam: Cannot typically be machine washed; spot clean and vacuum regularly

• Down/feather: Machine washable with gentle cycle and thorough drying

• Synthetic fill: Most durable for washing; follow care label instructions

• Latex: Usually not washable; protect with waterproof covers

Can Pillows Go in the Dryer?

Most washable pillows can and should be dried in a dryer to prevent mildew. The key is using low heat and adding dryer balls or tennis balls to prevent clumping. Complete drying is crucial—even slightly damp pillows can develop mould in their core.

When Should You Replace Your Pillows?

Even with regular washing, pillows have a limited lifespan:

• Polyester pillows: Replace every 1-2 years

• Memory foam: Replace every 2-3 years

• Down/feather: Can last 5+ years with proper care

• Microfiber pillows: Often maintain proper support for 3-4 years with regular care

The simplest test: Fold your pillow in half. If it doesn't spring back to shape, it's time for a replacement, regardless of how clean it may be.

Pro tip: Use pillow protectors under your pillowcases. These zippered covers create an additional barrier against allergens and extend the life of your pillows whilst making maintenance easier.

The Bedding Hygiene Cheat Sheet: Quick Reference Table

What Temperature Should You Wash Bedding At?

For maximum hygiene, wash bedding at the highest temperature the fabric can safely handle:

• Cotton and linen: Can typically withstand hot water (54°C+), which kills dust mites

• Synthetic materials: Warm water (40°C) is usually recommended

• Silk and delicates: Cold to warm water (27°C)

• Brushed microfiber (like Pamposh): Can withstand hot water washing whilst maintaining softness and durability, making it ideal for allergy sufferers who need high-temperature sanitisation

Always check care labels, as using water that's too hot can damage certain fabrics and cause shrinkage.

Common Bedding Hygiene Mistakes to Avoid

Even well-intentioned cleaners make these common bedding mistakes:

1. Washing in cold water only: Whilst energy-efficient, cold water doesn't kill dust mites or remove body oils effectively. Use hot water monthly for a deep clean.

2. Skipping pillow and duvet care: Focusing only on sheets and pillowcases leaves a significant source of allergens untouched. Set calendar reminders for these less frequent but important washes.

3. Not checking care labels: Different materials require different treatment. That silk pillowcase needs gentler handling than cotton sheets.

4. Overloading the machine: Cramming too much bedding into one load prevents proper cleaning and rinsing. Your bedding needs room to move freely.

5. Forgetting to dry bedding completely: Damp bedding is a breeding ground for mould and mildew. Ensure everything is 100% dry before remaking your bed.

6. Making the bed immediately after waking: Allow your sheets to air out for 20 minutes to release moisture before making your bed each morning.

Can Damp Bedding Cause Mould?

Absolutely—and it happens more often than you might think. Bedding that feels dry to the touch may still retain moisture in its core, particularly pillows and duvets. This hidden dampness creates the perfect environment for mould spores to thrive, potentially causing respiratory issues and allergic reactions.

Always ensure bedding is completely dry before storing or reusing it, even if it takes multiple drying cycles.
