Top Tips On How to Cool Down a Bedroom at Night

Jun 2, 2024 | Bedroom Environment

With temperatures (finally!) creeping up across the UK, you may find the warmth plays havoc with your sleep – leaving you feeling restless and exhausted. In this blog post, we’re sharing how you can cool down your bedroom to keep it at the ideal temperature of around 16-18°C (60-65°F) during those hot summer nights.

It can be difficult to keep your bedroom cool at bedtime when the outside temperature typically remains higher and your bedroom has retained the heat from the day. While it’s lovely to have the sunshine and warmth during the day, it’s never fun sleeping at night in a bedroom that feels like an oven!

10 simple tips for cooling down your hot bedroom:

  1. Encourage Airflow

Open windows and interior doors to create a cross-breeze that circulates cooler air throughout your room. The more airflow, the better.

  1. Block Out the Sun

Keep curtains or blinds drawn during the day to stop the sun from heating up your room. Blackout curtains are especially effective at reducing heat gain.

  1. Open the Loft Hatch

If you have an attic or loft space, open the hatch. Hot air naturally rises, and this gives it an easy escape route—helping to reduce the temperature below.

  1. Swap Heavy Bedding for Lightweight Sheets

Ditch the duvet and sleep with a lightweight cotton sheet or a low-tog summer duvet. Breathable fabrics will help regulate body temperature and reduce night sweats.

  1. Use a Fan with Ice

Position a bowl of ice or a frozen water bottle in front of an electric fan to create a DIY air conditioner. The fan will circulate cooler air around the room.

  1. Choose Light Cotton Sleepwear

Wearing light, breathable cotton is better than sleeping naked—it absorbs sweat and helps your body stay cool. Take a cool shower or bath before bed to lower your core temperature.

  1. Watch What You Eat and Drink

Avoid caffeine, alcohol, or heavy meals close to bedtime. These can raise your body temperature and disrupt sleep. Stay hydrated by drinking cold water throughout the evening and keep a glass by your bed.

  1. Size Matters When Sharing a Bed

If you’re sharing your bed, make sure it’s wide enough—at least 5ft (150cm)—to give both sleepers enough space and reduce heat buildup.

  1. Consider Sleeping Separately

Two bodies in one bed naturally increase heat. If you’re still overheating, consider separate beds during especially hot nights.

  1. Choose a Cooling Mattress or Bed Frame

Invest in a bed designed with temperature-regulating features such as moisture-wicking fabrics, breathable layers, or built-in cooling technology for enhanced comfort during summer months.

As well as bedroom temperature, sleeping well depends on various factors in your bedroom environment, including light, noise and the comfort of your bed. Discover how to create the perfect bedroom sleep environment.
