Sleeping when it’s cold outside

A quick non-scientific survey of friends and colleagues suggests that about half people like to be cool
when they sleep, while half prefer to be warm. What is unclear, however, is whether being warm of
cold is better for our health. Does this vary dependant on the individual?

There is no doubt that humans are pre-programmed to want to store up fat and spend longer
periods of inactivity during winter. Whilst this is not quite hibernation, it is coded in our genomes to
conserve vital energy and store weight during the darker months. When winter starts many people
start to put more covers on beds and buy a warm pair of PJs. Many people admit to wearing warm
socks at night.

More than anything, though, we think it’s time to turn on the heating. As well as costing more
money, the problem with excessive heat is that it can disturb our sleeping patterns. A Daily Mirror
article and survey published in September 2017 suggests that 50% of respondents, “had problems
sleeping because their rooms were too toasty.”

The reality is that sleeping in temperatures over 65º F isn’t good for our health (or the planet).
There is a large weight of advice that indicates we should let our bedrooms cool down at night if we
want to stay in good shape and sleep well. This is expressed well on who say,
“When you sleep your body temperature goes down and then starts to warm up towards the end of
your sleep as a signal to wake up. So if you sleep in a cooler room you are likely to be more
comfortable, less likely to wake up during the night and generally get a better night’s sleep.”

The scientific reason for the above point is that our bodies can activate their thermo-regulation
systems at moderate temperatures. In other words, if we put on too many layers, our bodies
become lazy.

Also, if we keep the ambient temperature between 60 ºF and 65 ºF, it helps our bodies wake up
easier, which helps us to stay active during the day.
