Is Your Bedroom Too Hot to Sleep? (Here’s What to Do About It)

Rest deeper. Wake fresher. Live better.

You’ve tossed, turned, flipped the pillow a hundred times - and still, you’re too hot to drift off.

Whether it’s a heatwave, a stuffy flat, or simply a mattress that traps heat, trying to sleep in a hot bedroom can feel like torture. But it’s not just uncomfortable, it can seriously affect your sleep quality.

Let’s break down why temperature matters for sleep, what the ideal bedroom climate looks like, and how you can cool things down tonight.

Why Heat Makes It Harder to Sleep

Your body is naturally designed to cool down as you fall asleep. In fact, your core temperature drops about 1°C during the night to signal to your brain that it’s time to rest.

But if your room is too warm, that cooling process gets disrupted, and so does your sleep cycle. You might:

• Struggle to fall asleep

• Wake up frequently

• Get less deep sleep or REM

• Feel groggy, cranky, or restless the next day

Translation: You’re sleeping, but not restoring. And that’s a big problem.

What’s the Best Temperature for Sleep?

According to sleep experts, the ideal bedroom temperature is between 16°C and 18°C (around 60–65°F).

Cooler rooms help your body regulate its circadian rhythm and move smoothly through each stage of the sleep cycle — especially deep sleep, which is when most of your physical repair happens.

Too cold? You’ll shiver.
Too hot? You’ll toss.
The goal is a Goldilocks zone - cool, calm, and breathable.

7 Ways to Cool Your Bedroom for Better Sleep

Here’s how to take control of your sleep environment when things start heating up:

1. Open windows (but close curtains)

Create airflow by opening windows in the evening, but keep blackout curtains or blinds closed during the day to block out direct sun and reduce trapped heat.

2. Switch to breathable bedding

Avoid heavy duvets, flannel sheets, or synthetic fibres. Instead, opt for lightweight, moisture-wicking materials like cotton, linen, or bamboo.

3. Ditch the memory foam (or upgrade your mattress)

Traditional memory foam holds heat. If you're always overheating, consider a more breathable hybrid mattress or one with cooling gel layers.

4. Use a fan - wisely

A rotating fan can keep air moving and make a room feel cooler. Place a bowl of ice in front of the fan for an extra chill factor (yes, really).

5. Cool your body, not just the room

Take a lukewarm shower before bed, use a cool flannel on your wrists or neck, or keep a chilled water bottle by the bed.

6. Sleep low

Heat rises - so if you’re in a loft or on an upper floor, try sleeping on a lower level if possible, or even moving your mattress to the floor on very hot nights.

7. Keep electronics out of the bedroom

TVs, laptops, chargers - they all give off heat. Unplug what you don’t need and give your space a cooler, calmer energy.

Final Thought: Cool Room, Cooler Sleep

If you're serious about sleeping better, don’t ignore the thermostat. Your body needs to feel safe, cool, and calm to drop into its deepest, most restorative sleep.

So tonight, crack a window. Swap the duvet. Ditch the stuffy bedding.

You might just wake up feeling fresher - and cooler - than you have in weeks.

Rest deeper. Wake fresher. Live better.
