A good night's sleep plays a critical role in health and overall well being. That’s why on Monday, Fitbit announced two new sleeping tools that will be coming to its existing products. The first, Sleep Stages, will utilize the optical heart-rate sensor to estimate how long you spend in light, deep and REM sleep cycles. It will also estimate how frequently you wake up in the middle of the night. The second tool, known as Sleep Insights, will provide users with personalized guidance and coaching to help improve the quality of their sleep.https://www.cnet.com/news/fitbit-slee...http://www.wochit.comThis video was produced by YT Wochit Tech using http://wochit.com
