The ideal temperature for sleep is different for each person. But people usually sleep more comfortably if the bedroom is cool, rather than warm. The reason is that when you want to sleep, your body starts to cool down naturally to prepare you for sleep. Therefore, by cooling down the bedroom temperature, you are helping your body’s natural cooling process, that helps you fall asleep faster.

The best temperature for sleep is 60-67 degrees Fahrenheit, or 16-20 degree Celsius. It might sound a little cold, but this is the suggested temperature by specialists.

For babies and younger people, the ideal temperature for bedtime is a little higher, 65- 70 degrees Fahrenheit or 19-21 degree Celsius. However, it does not mean that colder room temperatures result in a better night’s sleep. Temperatures above 75 or below 54 degrees can both interfere with sleep quality.

Let’s get a more scientific look at this:

Our body temperature naturally fluctuates during the day. From around 11 am to to 10 pm, the body temperature is usually around 98 degrees Fahrenheit or 36.5 degree Celsius. When your body gets tired late at night, it starts to cool down. This temperature-drop sends a signal to your brain that this is bedtime. So, the brain increases the secretion of the sleep hormone, melatonin, which regulates your sleep.

It is worth mentioning that your mattress quality plays an important role in regulating your body temperature during sleep. Memory foam beds trap heat while cooling mattresses provide a cooler sleep surface that can bring you a deeper sleep.
