It's not good for our in-built sleep timer

By Lisa Joyner

With winter on its way, some people might be tempted to sleep with the central heating on to keep warm during the night – but new research has found that it might not be good for our health.

According to doctors, falling asleep with the heating on can result in a restless night's sleep as our bodies can overheat much more quickly. As well as not being able to sleep soundly, it may also be causing our skin to appear dry, red and itchy the following morning.

In fact, doctors recommend that, in order for us to fall asleep faster and deeper, it's better to have a slightly cooler room so our brain temperature can remain lower than the rest of our body. This helps the 'circadian timer' in our brains function most efficiently.

According to scientists from the University of Southern Australia, those who suffer from insomnia typically have a higher temperature when they first go to bed — meaning that they are finding it difficult to nod off.

Dr Cameron Van den Heuvel told Yahoo UK: "This results in a state of heightened arousal that prevents them from falling asleep when they go to bed, probably because they have to wait for their bodies to lose the heat that's keeping them awake.

"We're only talking about a half to one degree [Celsius] (32.9°F-to-33.8°F) but that small temperature change can result in significant differences in arousal between insomniacs and people without sleeping problems."
