I said yes (to sleep tracking). I've tested around 20 sleep sensors including masks, watches and devices going under the mattress. The Sleepon ring promises to track sleep, wake the user up if their blood oxygen level is low and has an integrated smart sleep alarm function too. It sounds like the sleep tracker jackpot so I had to test it. Here is what I learnt after the first night. I don't have sleep apnoe, my sleep score is high but my deep sleep was not long enough. My oxygen level was normal and only turned around 8 times. There are things to improve and I haven't tested the smart sleep alarm function, the Holy Grail of sleep tracking, but will do tonight. I'll keep you posted. https://www.sleepon.us / #themedicalfuturist #digitalhealth #future #healthcare #medicine #technology #wearable #health #healthy #fromchancetochoice #sleep …see more
