When it's too hot to sleep, the night drags and the next day suffers. The fix works on three levels — the room, the bed, and your body. Tackle all three and even a heatwave night becomes restful. Here's how.
Cool the bedroom (all day, not just at night)
The work starts long before bedtime. Shade the bedroom windows from outside during the day so the room never bakes, keep the door closed to the hot side of the flat, and ventilate hard once the outside air drops in the evening. A bedroom you've kept cool all day is far easier to sleep in than one you try to cool at 11pm. For attic bedrooms, see our Dachgeschoss guide.
Cool the bed
Your bedding traps heat against you. Switch to lightweight, breathable cotton or linen sheets, ditch the heavy duvet for a thin cover or just a sheet, and consider a cooling mattress topper that doesn't hold heat the way a thick mattress does. See our cooling bedding guide. A breathable bed lets your body shed heat instead of stewing in it.
Cool your body
Lower your own temperature before and during sleep:
- Take a lukewarm shower before bed — not ice-cold, which triggers a rebound warm-up.
- Aim a fan across your body so sweat evaporates; a quiet model doubles as white noise. See fans in stock.
- Cool your pulse points — a damp cloth on the neck or wrists.
- Wear loose, light nightwear or less.
- Stay hydrated so your body can sweat and cool itself.
Keep one room as your cool retreat
You don't need to cool the whole flat to sleep well — you need one cool room. Concentrate your shading, ventilation, and cooling gear on the bedroom, and close it off from the rest of the home. A single well-managed room beats a marginally-cooler whole flat every time.
When you need more
If the nights are relentless — humid heat, a top-floor flat, or a vulnerable sleeper — step up to active cooling. An evaporative air cooler helps in dry heat, and a quiet mobile AC on sleep mode genuinely cools a sealed bedroom. Pre-cool the room before bed so the unit runs gently and quietly overnight.
The takeaway
Sleep in the heat by cooling the room all day, the bed with breathable bedding, and your body with a lukewarm shower and a fan. Keep one room as your retreat, and add a cooler or AC for the worst nights. Check what's in stock near you to make tonight more sleepable.
