How to Sleep in a Heatwave: 10 Tips to Stay Cool Tonight

When temperatures rise, getting a good night's sleep can feel impossible.

If you've found yourself tossing and turning, kicking off the duvet or searching for the cool side of the pillow, you're not alone. Our bodies naturally need to cool down before we fall asleep, so a heatwave can make drifting off much more difficult.

The good news? A few small changes can make a surprisingly big difference.

Here are 10 practical ways to sleep better during hot weather.

1. Keep your bedroom as cool as possible

Close curtains or blinds during the hottest part of the day to stop the sun heating your room. Once the outside temperature drops in the evening, open windows to encourage cooler air to circulate.

2. Choose breathable bedding

Natural fibres such as cotton and linen allow more airflow than synthetic fabrics.

If your duvet feels too warm, swap it for a lightweight sheet until temperatures return to normal.

3. Take a lukewarm shower before bed

It might seem tempting to jump into an ice-cold shower, but very cold water can actually make your body work harder to stay warm afterwards. A lukewarm shower helps your body cool naturally before bedtime to help signal to your body on how to sleep in a heatwave.

4. Dim the lights in the evening

Light is one of the strongest signals your brain uses to know whether it's time to be awake or asleep. Lower lighting in the evening helps create an environment that supports your natural wind-down routine.

5. Stay hydrated throughout the day

Even mild dehydration can make hot nights feel even more uncomfortable.

Drink water regularly during the day, but avoid drinking large amounts immediately before bed to reduce unnecessary night-time trips to the bathroom.

6. Avoid heavy meals and alcohol late in the evening

Digesting large meals generates heat within the body. Alcohol may initially make you feel sleepy, but it can reduce sleep quality and contribute to waking during the night.

7. Create a calming bedtime ritual

Your evening routine matters just as much as your bedroom temperature.

Simple rituals such as reading, lowering the lights, enjoying herbal tea or using a botanical pillow mist can help create a calm transition between a busy day and a restful night.

8. Let your skin breathe

Loose-fitting cotton sleepwear—or even sleeping without pyjamas if you're comfortable doing so—can help reduce overheating during the night.

9. Keep electronics to a minimum

Phones, tablets and laptops don't just emit light; they also generate heat and encourage mental stimulation. Give yourself 30–60 minutes away from screens before bed whenever possible.

10. Don't chase sleep

Ironically, worrying about not sleeping often makes it harder to fall asleep. If you can't sleep after around 20 minutes, get out of bed, do something relaxing in dim light and return once you begin to feel sleepy.

Final Thoughts on how to sleep in a heatwave

Heatwaves don't have to mean sleepless nights. Small changes—cooler bedding, softer lighting, better airflow and a calming evening ritual—can help create an environment where your body naturally feels more ready for sleep. At Snoozing Angel, we believe bedtime should be the best part of your day, whatever the weather. Sometimes, it's the smallest evening rituals that make the biggest difference.
