The Hidden Effects of Temperature on Sleep

Have you ever been lying awake at night unable to get to sleep? 
Well temperature just might be the hidden culprit keeping you up at night.

Sometimes you just know that it’s too hot, like on those hot summer nights spent tossing and turning, or if your partner is a blanket-stealer and you’re left shivering all night. What you might not realise is that even less obvious temperature changes can disrupt your precious sleep.

So how does temperature affect sleep?

Research shows us that a drop in your internal temperature is actually part of the body’s signals to your brain that it’s time for sleep, so a cooler bedroom is generally better for getting to sleep!  In fact around 16-18 degrees Celsius is the recommended room temp.

There have been scientific studies into the connection between warmer core body temperatures and insomnia.  When it’s too warm your REM sleep (the good stuff) can be disrupted.

Benefits of sleeping in a cooler room

There’s other benefits to sleeping in a cooler room; some studies have linked cooler sleeping temperatures with increased metabolism (how our bodies store and burn fat).   

It also helps your body regulate melatonin (a super helpful anti-ageing hormone!) which in turn encourages our body to sleep better.

How to stay cool

Ideally your bedroom should be cool, dark, and quiet – think of it as your own little hibernation cave.

Your mattress might actually be part of the temperature problem too, some mattresses can trap heat causing you to wake up hot and bothered.  

Our Zeek Mattresses are designed right here in Australia by a bunch of sleep obsessed Aussies,  specifically for our hot climate. Clever air foam combined with a breathable Tencel cover helps regulate your body temp and keep you cool all night long!

Your brain also likes it cool, so a cool pillow can make all the difference to maintaining your ideal temperature.  If you're a little bit of a hot head, then our Ice Pillow is just for you.

Changes in temperature aren't the only cause of sleep disruption and insomnia. Research also highlights other conditions that can disrupt your sleep.  If you are struggling with ongoing or chronic sleep issues we recommend chatting to your GP or seeking specialised medical advice.
