What is the best AC temperature for sleep?
The best AC temperature for sleeping is between 60 – 67 degrees Fahrenheit. Any temperature above 70 degrees Fahrenheit can lead to reduced REM sleep, undermining your health.
Temperature affects the quality of your sleep because it’s one of the signals that your body uses to regulate your circadian rhythm. Circadian rhythm is your body’s internal clock and triggers hormonal changes depending on the time of day that make you feel hungry, tired, or wide awake.
The challenge in sleeping during hot summer days is that our bodies use the natural fall in temperature at the end of the day to trigger the release of sleep hormones. When temperatures stay above 70 degrees, we get fewer of those hormones and can struggle to get to sleep.
The temperature continues to affect sleep once you’ve nodded off. Your body is designed to steadily lose heat over the course of the night, which facilitates the deeper phases of sleep. Hot temperatures not only make it harder to fall asleep, they also make your sleep quality worse.
