Are you too hot or too cold when trying to drop off to sleep? Maybe you're trying to be money conscious by keeping the temperature as low as possible in the winter and as high as possible in the summer, but if you didn't know, your thermostat can make or break your slumber. For some, the temperature has to be just right for an ideal night's sleep.
In general, the suggested bedroom temperature should be between 16 and 20 degrees for optimal sleep. When lying in bed trying to sleep, your body temperature decreases to initiate sleep, so having your room at the ideal temperature can help you to drop off. If your room is cool, rather than warm, it will be much easier to shut your eyes for the night. Thermostat settings far lower or higher than what's recommended could lead to restlessness and can also affect the quality of REM (rapid eye movement) sleep.
Wool is fantastic at helping to regulate sleeping temperature. A recent sleep study conducted by The Woolmark Company and the University of Sydney examined a variety of bedding products in a range of temperature and humidity environments, and wool was selected as the “undoubted winner.” This study proved wool breathes better than synthetics, increases periods of deep REM sleep, and also gets the body to a comfortable sleeping temperature quicker and maintains it for a longer period of time.
It can also help to think of your bedroom as a cave—it should be quiet, cool, and dark for the best chance at getting enough rest.
And if you're trying to get your baby or toddler to bed, raising the thermostat a little higher between 18 and 20 degrees will suffice. Just make sure to keep the cot or bed away from windows or fans, and be certain that the temperature stays consistent.
