1.Lower Your Room Temperature
One of the most obvious ways to sleep cooler is to lower your thermostat. But do you know the optimal temperature? Experts say 60-67 F will allow your body to keep a core temperature that’s suitable for sleep. A room that’s too muggy can also affect your rest, so aim for 40% to 60% humidity.
2.Get Some Air Flowing
It can be expensive to run air conditioning, or you may not have it. Another option is to open windows and turn on a fan near one to create a cross flow of air. But if it’s too warm outside, in the mid-90s or higher, you’ll need more than a fan to avoid heat illness.
