Sleep longer and better by setting the AC to this number, says Health.
Your body temperature naturally drops to prepare for sleep, and many experts say you should keep your thermostat between 60 and 67 degrees Fahrenheit to help facilitate this decrease. But Chris Winter, MD, president of Charlottesville Neurology and Sleep Medicine in Virginia, tells Health that he thinks 65 degrees is ideal. “That doesn’t mean 66 or 67 is terrible, but a cooler environment usually lends itself to a better quality of sleep,” Dr. Winter tells Health.
