Key takeaways
- Percale cotton or linen for breathability.
- Wool or quality down-alternative duvets.
- Replace pillows every 1–2 years.
- Sheets and duvet covers weekly — hot wash.
Who this is for
Hot sleepers, allergy-prone households and sleep optimisers.
Why bedding matters
Temperature regulation drives sleep quality — your body needs to cool down to fall and stay asleep. Breathable fibres help it do that; sweaty synthetics fight it.
Sheets: cotton vs linen
Percale is the crisp classic; sateen is smooth and slightly warmer. Linen breathes best of all and softens beautifully with age — worth the investment if you sleep hot.
Duvets and pillows
Wool duvets regulate temperature naturally; down and quality down-alternatives suit different budgets and ethics. Choose washable pillows and replace them every 1–2 years — old pillows harbour dust mites and lose support.
Mattress basics
Use a washable protector, rotate the mattress occasionally, and vacuum it when the seasons change. Simple maintenance extends its life.
The weekly routine
Hot wash for sheets, air-dry when possible, and air the bedroom daily. Sunlight is a free disinfectant for pillows and duvets.
FAQs
Does thread count matter?
Less than fibre and weave. A 200-thread-count percale beats a 600-thread-count sateen for cool sleep.
Linen or cotton?
Linen breathes best; cotton percale is the crisp classic. Both beat synthetics.
How often to wash?
Sheets and duvet covers weekly; pillows quarterly; duvets a few times a year.
