Sleep experts say that paying attention to the room temperature may help people get more restful sleep and lead to more energy while awake, TODAY reported.

According to Dr. Karen Lee, from NYU Langone’s Epilepsy and Sleep Center, it tends to be better for people to fall asleep at a cooler temperature.

“If I was pushed to have to choose one or the other, I’d err on the colder rather than warmer temperature,” she said.

“When our core body temperature drops, melatonin secretion increases, which is needed for us to drift into sleep as well,” Lee explained. “And there’s this circadian timing that happens to all of us. And we want to make sure the temperature is not something prohibitive of that natural process for us.”
