Hot summer nights ruining your sleep? Here are 7 tested and approved tips to stay cool at night.
1. Close shutters and curtains first thing in the morning
As soon as the sun hits, close everything to block the heat. At night, open wide to let in the cool air.
2. Invest in linen or bamboo bedding
Cotton traps heat. Linen and bamboo are 30% more breathable — you sweat less, sleep better.
3. Take a lukewarm shower before bed
Lukewarm, not cold. A cold shower causes a rebound heat effect. A 25-27°C shower gradually lowers your body temperature.
4. Drink water at room temperature
Drinking ice-cold water means your body has to warm up to digest it, making you sweat. Prefer room temperature water with mint or lemon.
5. Use a quiet portable air conditioner
The most effective investment. A Coldest Breeze™ portable air conditioner at 56 dB (night mode 28 dB) cools your room to 22°C in 15 minutes — no installation needed. Cost: €0.20 per hour.
6. Place a wet sheet in front of the fan
Grandma’s trick: a damp sheet in front of the fan → cooling effect by evaporation. Free and eco-friendly.
7. Keep your pajamas in the freezer
Put your pajamas in a plastic bag in the freezer 15 minutes before bed. Chilly sensation lasts for 30 minutes.
Bonus: set the night mode
If you have a portable air conditioner, program the sleep mode with a 6-hour timer — economical and comfortable.
