According to Dr. Chris Winter of Huffington Post, science dictates that temperatures between 60 and 67 degrees Fahrenheit are ideal sleeping conditions. By sleeping at cooler temperatures, your body will thank you. According to a study published in Diabetes, lowering your thermostat a few degrees before bed can help decrease your risk of certain metabolic diseases, such as diabetes. In addition to the health benefits provided by sleeping amidst a cooler climate, there are a number of practical advantages, too, such as actually getting to sleep faster. According to Kathleen Doheny of WebMD Magazine, when we go to sleep, the desired temperature of our bodies drops. Heat exposure can actually affect slow wave sleep and REM sleep, while cold does not have these effects. High humidity is also associated with poorer sleep.

Lowering your thermostat might also keep your body healthier, Several studies provide compelling results suggesting that the temperature at which we sleep can impact our metabolism of fats. Men who slept at 66F for one month had a 42% increase in brown fat volume and a 10% increase in fat metabolic activity. Brown fat, as opposed to white fat, is the good kind of fat, which can help you to lose weight and protects against insulin resistance. Experts agree the temperature of your sleeping area and how comfortable you feel in it affect how well and how long you snooze. Why? When you go to sleep, your set point for body temperature -- the temperature your brain is trying to achieve goes down, says H. Craig Heller, PhD, professor of biology at Stanford University,
