The Health Benefits of Sleeping at Cooler Temperatures

Woman sleeping comfortably and healthily

In today’s world, we all take certain measures to try to be healthy. Whether it’s drinking more water, eating well or exercising, our days are spent trying to be healthier overall - but did you know that making healthy choices doesn’t have to stop once you go to sleep?

It’s true! A full night’s sleep doesn’t just help you feel more rested when you wake up, it can also benefit your heart, mind and weight. While these are significant benefits, the fact of the matter is, only about 44% of Americans report a restful night’s sleep almost every night. Although there are a variety of factors that can affect how you sleep, 69% of people reported that their bedroom temperature strongly impacts their ability to sleep well.

Benefits of Sleeping Cooler

Are you a part of the 56% that don’t always sleep well? Have you ever considered your bedroom temperature might be the culprit?

  • As you’re falling asleep, cooler temperatures can help you get to sleep faster, lower the risk of metabolic diseases like diabetes, increase your quality of REM sleep, and even help you look younger.

During a four-month study, researchers followed the sleep patterns of healthy young men. For each month they set their bedroom temperature to 75, 66, 75, or 81 degrees Fahrenheit. When the men slept with a bedroom temperature of 66 degrees, they doubled their volumes of brown fat (also known as the “good fat”), burned more calories throughout the day and improved their insulin sensitivity, which accelerates fat loss. Brown fat is metabolically active, meaning it burns calories to generate heat.

When you sleep at colder temperatures, your body burns brown fat so that you can generate heat while you sleep. During the warm month when the bedroom temperature was set to 81 degrees, these positive results were reversed. In a separate study, researchers found that turning the thermostat down to 66 degrees at bedtime could potentially burn an extra 100 calories over the course of 24 sleeping hours.

Although there appears to be a direct correlation between bedroom temperature and overall health, it’s important to understand that in most studies where cold temperatures influenced an individual’s metabolic rate, participants slept with thin sheets. When it’s time for bed, there are a variety of factors that can contribute to heated sleeping conditions, like pajamas, comforters, or even the body heat of another person.

According to Dr. Chris Winter of The Huffington Post, temperatures should be between 60 and 67 degrees Fahrenheit for ideal sleeping conditions. There are different levels of temperature comfort for everyone. Although there are a variety of factors that can contribute to a warmer environment, there are ways to determine your perfect sleep temperature without having to worry about wasting money trying to cool your entire bedroom.

With the Chili sleep systems, you’re able to control your individual sleeping temperature. It also only uses the same amount of energy as two light bulbs, so you won’t have to worry about outrageous cooling bills while you try to find your perfect temperature!

We also have a new heating and cooling weighted blanket called the chiliBLANKET that can help you achieve this too.
