Leveraging temperature for better sleep

There are ways that you can leverage temperature to take back control and actually get better sleep!

With an especially hot summer this year, a lot of people are wondering how changes in weather can impact their sleep. While some changes in temperature can hinder your sleep, there are ways that you can leverage it to take back control and actually get better sleep!


Researchers have known for years that overactivity in the brain is the most common root cause of a restless night’s sleep, but the dilemma has been how to reduce brain activity without introducing drug solutions that may have unwanted side effects.


Studies1 have found that metabolic activity in the frontal cortex of the brain was drastically decreased when the forehead is cooled, reducing the “racing mind” feeling experienced by many who have trouble sleeping. To achieve this, the forehead needs to be cooled to a specific temperature that is cool enough to reduce brain activity, but not so cold (like an ice pack) that it triggers the body’s pain receptors, which would have the opposite effect. This is where CoolDrift comes in. It cools the forehead to this effective temperature range and maintains a constant temperature throughout the whole night.


Paired with CoolDrift, there are additional steps you can take to optimize your sleeping temperature, and subsequently get better, more restful sleep.


-First and probably the most obvious is to properly set the room temperature in which you’re sleeping. Most suggestions have the optimal range between 60- and 67-degrees Fahrenheit.

-Next you should set a sleep routine, to better help your bodies’ circadian rhythm, and self-cooling mechanism. This should include shutting off the TV and other screens in the room, and potentially even doing some calming activities such as reading or meditating.

-Avoid food or drink that could increase your body temperatures prior to going to bed. This includes caffeine, chocolate, soda, and more.

Our bodies are a unique ecosystem that require specific environments to perform and function optimally. Our temperature regulation is part of that ecosystem, and the impact it has on sleep is significant. By better managing your bodies temperature, you can get a better night’s rest – improving your quality of life, physical and emotional wellbeing, and making you the best version of yourself possible.
