Body Thermoregulation in Sleep Nation

Body Thermoregulation in Sleep Nation

When we get into bed, often our minds wander. We may think about the work that needs to get done the next day, or we may reflect more intimately on our lives and wonder if our second grade crush Robbie was actually “the one.”  However, we tend not to think about the naturally occurring processes that can affect our sleep quality at night.

What is Thermoregulation?

Thermoregulation is a natural process that makes sure our bodies stay at a healthy core internal temperature. According to Healthline, this normal core temperature is between 98°F (37°C) and 100°F (37.8°C). If your body goes above or below these temperatures, there can be extreme health risks. Luckily, through thermoregulation your body will try to bring you back to a healthy internal temperature.

So what does this have to do with sleep? states that body and brain temperature fall during NREM (non-rapid eye movement) sleep. During REM sleep, the brain temperature increases.

When core body temperature drops, that’s when sleep usually occurs. Maintaining the right skin temperature is important for a sound sleep. When skin temperature is slightly raised, it does not affect core body temperature and has been shown to improve sleep quality.

Your bedroom temperature can affect thermoregulation. A bedroom that is too cool or too hot can mess up your sleep and prevent you from reaching deep sleep. Deep sleep is needed to feel well rested, but body thermoregulation is more effective in light sleep.

If you’re finding that you’re not well rested, it may be that your bedroom temperature has affected normal processes in your body. On the Eight app, you can see the temperature of your room and bed and make adjustments as needed. For some people, warming up before bed can improve sleep. With Eight’s warming feature, you can set the warmth individually on each side of the bed to get a better sleep.
