Sleeping in a clean bed is not a luxury: it’s a matter of health. Well-maintained bedding improves sleep quality, limits allergy risks, and preserves your comfort night after night. Here’s everything you need to know about how often to wash your sheets, pillows, duvets, and mattress.

Why should you wash your bedding regularly?

Every night, your body releases:

  • Between 0.5 and 1 liter of sweat
  • Dead skin cells, hair, makeup residues, or pollution

These elements nourish dust mites and promote bacteria and fungi. Poorly washed bedding can lead to:

  • Frequent awakenings
  • Skin problems (acne, eczema)
  • Respiratory allergies

Each item has its own maintenance frequency

Sheets, pillowcases, duvet covers

  • Standard frequency: every 1 to 2 weeks
  • Special cases:
    • In summer or during heat: once a week
    • Naked sleepers or those with pets: at least once a week
    • Children or sick individuals: 1 to 2 times a week

Pillows and duvets

  • Synthetic pillows: machine wash every 3 months
  • Feather or latex pillows: every 4 to 6 months, gentle wash or dry cleaning
  • Duvets: every 6 months, or once a year if well protected

Tip: use a washable protective cover to space out washes. Check out our complete guide on choosing a mattress protector to find the ideal protection.

And what about the mattress?

  • Even though a mattress isn’t washed like bedding, it also deserves regular attention. Airing it out each week by keeping the room well-ventilated and vacuuming it every 1 to 3 months helps limit dust accumulation and keeps your bedding healthier and more comfortable. Discover our detailed tips for cleaning and maintaining your mattress to extend its lifespan.

Good practices to remember

Washing temperature

  • 60 °C: ideal against dust mites (cotton, standard sheets)
  • 30–40 °C: for delicate or lightly soiled textiles

Always check the manufacturer’s label

Drying

  • Air drying: preserves fibers
  • Tumble dryer: convenient, but watch out for shrinkage

Airing and rotation

  • 10 minutes of airing per day
  • Rotate the mattress for even wear

Examples of profiles & adapted routines

  • Allergic person: weekly washing, essential protective bedding
  • Couple with pets: sheets every week, anti-dust mite vacuum
  • Baby or child: sheets 2×/week, washable mattress protectors, specific pillows
Protect your mattress with a quality mattress protector or mattress pad
