Why does being cool help you sleep?

There’s science behind cool temperatures helping you sleep. Talking to Web MD, Biology professor Horace Craig Heller says “when you go to sleep, your set point for body temperature – the temperature your brain is trying to achieve – goes down.”

Therefore, if your body temperature naturally drops as you go to sleep, turning down the heating could signal to your body that it’s time to rest and consequently induce sleep. Sleepadvisor.org recommends the average sleeping temperature at 15-20 degrees Celsius.

What is a summer duvet?

When it comes to the warmth or coolness a duvet offers you, it’s always best to look at the tog rating. Tog ratings are based on how much heat the duvet can keep in, so the higher the tog, the warmer the duvet. Therefore, your summer duvet tog rating should be around 2.5-4.5 togs. However, there are specially designed cooling duvets that are also perfect for summer that can measure up to 11 tog. It’s all about finding the balance between the tog and the materials the duvet is made from.

What is the best filling for a summer duvet?

For a summer duvet, materials which are breathable and contain natural fibres are best. For example, cotton is a firm favourite. Other popular fillings include duck feather and down as well as silk or wool.
