In short

Cool the room before you go to bed, sleep on light cotton, and choose a mattress that doesn’t hold heat.

Cool the room before bed

5 °C

That’s how much cooler our own office got after these changes, with nothing else different.

  • RoofA white sun-reflecting paint or a lime coat keeps the top floor cooler.
  • WindowsLight curtains with a blackout lining. A sun film on west and south windows.
  • Fresh airOpen the windows early in the morning and at night, when the air is coolest.
  • PlantsAloe vera, snake plant, money tree and spider plant are easy to keep.

Cool yourself

  • Take a lukewarm bath before bed, not a cold one. A very cold shower makes your body work to warm up again.
  • Use light cotton sheets in light colours. Skip satin and polyester in summer.
  • Keep cold water by the bed. A sip, or a cool towel on your forehead, helps.
  • A small fan on your side if you feel the heat and your partner doesn’t.
  • Eat light at night. Cooling summer fruits help: fruits and vegetables for sleep.

The best AC temperature for sleep

Sleep experts suggest a room at 18 to 22 °C. If that feels too cold, or the bill too high, switch the AC on an hour before bed to cool the room, and use the timer so it doesn’t run all night.

Your mattress in summer

Memory foam holds body heat. Latex stays closer to room temperature, so you sleep cooler (latex vs memory foam). The Latex Plus 4 Mattress is all natural latex, under an organic cotton cover that zips off to wash.

Use a breathable protector. The Mattress Protector is soft terry cotton with a waterproof layer underneath, so sweat stays out of your mattress and the air still moves.

Questions people ask

I still wake up hot at night. What else helps?

Keep the room dark in the day, sleep with the fan on low, and read how to sleep deeper for habits that help you stay asleep.

Which Sunday mattress sleeps coolest?

The Latex Plus 4 Mattress. It is all latex, with no memory foam layer to hold heat.

Should I take a cold shower before bed in summer?

A lukewarm one is better. After a very cold shower, your body works to warm itself up again.

Will a protector fit my mattress?

The Mattress Protector fits mattresses up to 12 inches thick and covers the sides too, like a fitted sheet.

How can I keep my bedroom cool without AC?

Open the windows early morning and at night, keep curtains closed in the day, paint the roof white, and add a few plants.
