🌙 Your bedroom environment could be working against your sleep.
We spend roughly a third of our lives sleeping, yet often overlook one of the simplest factors influencing sleep quality: temperature.
Here's what's happening.
Your body naturally regulates its temperature around your sleep-wake cycle. As bedtime approaches, your core body temperature begins to drop, helping prepare your body for sleep.
When your bedroom is too warm, releasing that heat becomes harder, potentially making it more difficult to fall asleep and stay asleep.
Research has found associations between warmer bedroom temperatures and poorer sleep efficiency.
So here's your practical sleep upgrade:
Try these simple changes:
✅ Keep your bedroom comfortably cool rather than stuffy.
✅ Use lightweight, breathable bedding.
✅ Choose comfortable sleepwear that doesn't trap excessive heat.
✅ Open windows when the outside air is cooler, or use a fan when appropriate.
✅ Reduce heat entering your bedroom during the day by closing blinds or curtains.
What temperature should you aim for?
Around 18–20°C is a useful starting point for many adults, but there's no universal perfect temperature. Your bedding, climate, humidity and personal comfort all matter.
And remember, if you share a room with young children, their safe sleep temperature requirements need separate consideration.
You don't necessarily need a fancy mattress, cooling gadget or another supplement.
Sometimes, the best upgrade is improving the environment you're already sleeping in.
Don't just focus on what you do before bed. Look at where you sleep.
Your bedroom should be part of your recovery strategy.
