Fitness tracker sleep data - extremely low deep sleep.

Hello both, I am using a Samsung Galaxy watch to track my sleep. I read in forums that these are not that accurate. I only use them to see trends though there should be a grain of salt on the results. I replied to this post to see if you are tracking blood oxygen. Mine dips below 90% usually 85% for a total of 3 minutes. (the longest was 8 minutes). However, I am fully awake and do not feel tired upon waking up. Hope you make good progress in sleep. I think I need to have a sleep study soon!

Yes, am tracking the O2 saturation, but only for 4 hours overnight. So far, mine have been consistently average of 92-93% and lows of 85-87%.

The Sleep Foundation states this regarding levels during sleep: "People should contact a health care provider if their blood oxygen levels drop below 93%, and they should seek prompt medical care if levels are below 88%."

Same article says: "However, blood oxygen levels at or below 88%
for five or more minutes during sleep may be a sign of a sleep-related breathing disorder.

Thanks for your wishes about good progress. Same to you.

My Fitbit Versa 4 tracks oxygen saturation when it works. I have to make sure it's secure on my wrist so have to slide it a little higher on my arm and even then it only works half of the time. Not sure if my movement during the night is the issue or some other problem.

Happy Zzzzz's and Thanksgiving!
