This week at Fullpower, we continue to drill down our accurate multi-year data set that comprises 250+ million nights of sleep.  We found some new interesting weekly patterns within the previously identified seasonal patterns. This infographic shows weekly zoomed-in in heart rate. The Fullpower Sleeptracker platform captures continuous heart rate throughout the night. 

Seasonal changes occur with lower heart rates in the summer and higher in the winter.  This same pattern was also observed in this independent study in Japan. Our AI-powered analytics discovered this independently, and then we found this very interesting Japan paper.

Notice week after week, there is a consistent weekly cycle with lower heart rates early in the week leading to higher heart rates on the weekends and then recovery. Interesting.
