The thing is, not everyone has the luxury of central air conditioning. A box fan is an inexpensive alternative that can also improve air flow, but if you’re sleeping under a thick, suffocating blanket, you may still experience night sweats. Excess sweat may also increase the humidity under the blanket and cause extreme temperature changes if you kick the blanket off in the middle of the night. But don't worry, sweaty sleepers, we've got your back.
According to research done by scientists Kazue Okamoto-Mizuno and Koh Mizuno at Tohoku Fukushi University in Japan, "thermal environment is one of the most important factors that can affect human sleep." Turning down the thermostat can be an easy fix that makes a big difference to your quality of sleep.
TIP: If you live in a big city and there’s a lot of noise, light or air pollution outside your window, you might want to invest in an air purifier instead of cracking a window. These can make the air very dry, so make sure to get one with a built-in humidifier.
Research done at the Energy Technical University of Denmark shows that sleeping with a closed window and with no source of fresh air causes CO2 to build up in the room overnight. This problem is especially prevalent in countries that experience extreme temperatures and require more artificial conditioning. The results of the study show that increased CO2 levels during sleep lead to increased feelings of fatigue and reduced performance the next morning.
