"We are sabotaging ourselves (and our sleep) with our mattresses and the thermostats we set in our house, says Tara Youngblood, co-founder and Chief Science Officer of Chili Technologies. “Our human circadian rhythm follows the outside weather pattern.  If you are in an indoor, temperature controlled environment with no natural temperature fluctuations, there's nothing to signal the body that it's time to go to sleep." Youngblood talks about how most mattresses are made of foam or gel, causing body heat to reflect back as the night goes on.  "So they really heat us up when we really want to be coolest”. Youngblood describes three different zones of your sleep as it relates to body temperature and fluctuations.   The first zone is when you first get into bed.  This is personal and all about what feels comfortable and what triggers you to fall asleep.  This is when you flip on your "sleep switch" however it works for you.  The second zone is deep sleep which we get most of during the first half of the night, and when our body temperature should be cooling down.  When we sleep in a colder environment, the amount of deep sleep we get increases.  Deep sleep allows your body to recover and makes you feel rested in the morning.  Deep sleep is the most restorative form of sleep and boosts your immune system. The last zone is the second half of the night or the early morning.  At this time, your sleep cycles tend to be heavier on REM sleep and our body temperature rises. As your body warms up, you flip off the "sleep switch" and wake up feeling refreshed and rested. Youngblood describes the ChiliPad as "a mattress topper that circulates temperature controlled water (55-110 degrees) allowing you to optimize your sleep environment.  The Ooler is the same with a few upgrades.  It allows you to set a schedule that changes the temperature throughout the night.  It also has a quieter fan (if you want) and it is app-controlled." Youngblood is also author of a new book called Reprogram Your Sleep.  She explains in her book how each individual is unique and you need to find the "recipe" for good sleep that works for you. The message that Youngblood wants you to know is that "poor sleep is fixable".  Her book will teach you how to fix a dysfunctional circadian rhythm.  You will learn to identify what your personal circadian rhythm is and how to use that to get more out of your day and night.  Simple action steps like adjusting when you eat, exercise or relax can help you recover your sleep and teach you how to reset your circadian rhythm. Youngblood ends our podcast with this:  "Good sleep is built with consistent habits and patterns. Discover your hidden potential and true self, because even just one night of great sleep can change your day." For more information, please visit:  www.chilitechnologies.com
