An increasing amount of evidence suggests that in order to fall asleep and stay asleep your body temperature needs to drop by 1-3 degrees, in the morning your body needs to heat up by about the same amount. The problem with most people's sleeping environments is that even though the room might be cool, the area where you actually sleep is hard to regulate in terms of temperature. Many people experience heat as a major cause of waking up in the middle of the night. Even worse is that this heat can also limit your ability to go back to sleep.
During waking up there is also a role for temperature. Approximately 2 hours before you wake up your body temperature reaches its lowest point and starts to rise. This process supports your mood and energy levels in the morning.
Smart new devices are introduced to the market that provide people with the tools to regulate their body temperature at night, thereby dramatically increasing the quality of sleep.
Temperature regulating pillows like the Khione CoolPillow, and even full mattresses are increasingly popular among those that are interested in optimizing their sleep. These devices can provide the cooling signal to one's circadian clock telling the body it's time to go to sleep. In addition, these devices can also sustain cooling for longer periods at night, enabling deeper and more restorative sleep. And when properly timed, these methods can also provide the waking up trigger by increasing the temperature slightly 2 hours before one plans to wake up.
With an increasing emphasis on cognitive fitness and celebrities like Andrew Huberman promoting the importance of a good night's sleep for wide audiences, sleeping well is becoming broadly accepted as one of the most important ways of staying and feeling well.
