Sleep is a crucial aspect of our overall health and well-being, and understanding the factors that can influence its quality is essential. One such factor is temperature, which can play a significant role in the sleep process. Research has shown that our body's temperature fluctuates during sleep, and these fluctuations can impact the quality of our rest. With the latest update to our sleep tracking app, Pillow, you can now effortlessly track your temperature during sleep, empowering you to optimize your sleep environment and improve your overall sleep quality.

The Science Behind Sleep and Temperature

Numerous scientific findings have established the connection between sleep and temperature. Our body's core temperature follows a circadian rhythm, naturally decreasing during the night to reach its lowest point in the early hours of the morning (Kräuchi, 2002). These temperature fluctuations have been linked to sleep stages and the overall quality of sleep.

Ambient temperature, or the temperature of our sleep environment, plays a significant role in determining the quality of our sleep. Studies have shown that ambient temperature affects sleep stages, particularly slow-wave sleep (SWS) and rapid eye movement (REM) sleep (Okamoto-Mizuno & Mizuno, 2012). An overly warm sleep environment can lead to reduced SWS, while excessively cold temperatures can cause disruptions in REM sleep (Kräuchi, 2007).

Optimizing your sleep environment's temperature can significantly impact your sleep quality, as it facilitates the natural fluctuations in core body temperature that promote restful sleep. By monitoring and understanding these fluctuations with Pillow, you can make informed decisions on adjusting your sleep environment to enhance your sleep quality.
