However, have you ever considered whether the temperature might be the thing stopping you drifting off at night?
While keeping energy costs down is an obvious concern, notching the thermostat up just a couple of degrees could set you up for a much better night’s sleep.
How does temperature affect sleep?
While we know that the body’s sleep cycle is largely determined by the exposure to light, your brain also needs to drop your core body temperature to allow you to sleep.
If your surroundings make it too hot or too cold for the body to drop to this optimum temperature, you’ll probably find it harder to get to sleep.
The tendency is for people to set the thermostat just a little bit warmer than they actually need to, but the body needs to drop by a couple of degrees to signify to the brain that it’s time to sleep.
The average bedroom temperature is around 21 or 22°C, but according to researchers somewhere closer to 18°C could result in a much better night’s sleep.
The theory was backed up in a study published by the ‘Current Biology’ journal in October last year.
The study looked at the sleep patterns of 94 people in preindustrial societies, where temperatures are less controlled by things such as central heating and air conditioning.
While researchers expected the participants to go to sleep at sunset and wake up at sunrise, they found that sleep coincided with the coldest part of the night, and that participants slept an hour longer during winter.
What can you do?
While keeping the temperature down here in the UK isn’t much of a challenge here in the UK, sometimes in the summer it can get a bit warm and sticky so if this is the case we recommend moving to a duvet with a lower tog rating.
On the other hand, if you’re finding having the heating off is too chilly, throw on some extra blankets or try wearing socks, the hands and feet are areas where the body naturally tries to lose heat.
Another top tip is to run a warm bath before going to bed, which brings circulating blood to the surface and drops the body’s core temperature.
Not only should this help you get off to sleep better, but should result in a better, deeper level of sleep.
So while it could be down to any number of causes, next time you’re struggling to get to sleep, consider the temperature of your room.
