A lot of things affect whether you get a good night’s sleep, from noise to your mattress to what you do before bed. But what about temperature?

Neurologist and sleep specialist Dr. Christopher Winter explained in a Huffington Post column temperature can be the difference between whether you wake up groggy or relaxed, refreshed and ready to go.

Studies show the ideal sleep temperature is between 60 and 67 degrees. Sleeping at a cool temperature leads to a deeper and longer sleep and makes you feel more awake in the morning.

Hotter than 75 or colder than 54 are both bad for sleep. Sleeping in heat, especially with high humidity, can make for a more restless sleep.

But making your bedroom cool can be expensive in the summer.

Dr. Winter suggested performance bedding, gel mats that cover your mattress and cool you as you fall asleep, or the ChiliPad, which can cool or heat your bed throughout the night.
