Stress levels and deep sleep

i am very new to this but last week deep sleep and low stress readings went hand in hand, over the last few days my sleep is showing 4 to 5 hours of deep sleep and 4 hours of sleep but my stress counter is reporting only a couple of hours rest which is pushing the overall stress level very high. My heart rate while asleep seems ok. Can you have high stress levels while in deep sleep?

    Hi Sue,

    Yes. Yes, this is entirely possible.

    Light and Deep Sleep are being detected / ascribed based on accelerometer data, in other words, the magnitude and frequency of movement during the night. This doesn't necessarily correspond to your physiological states. Just because you aren't moving doesn't mean you're recovering quickly.

    Take an extreme example: alcohol is well-known to negatively impact recovery - the more you drink the worse it gets. And yet, it is very common for someone who has been over-served to lie down, pass out, and remain motionless for lengthy periods of the night. From an accelerometer perspective, this looks like deep sleep... from a physiological perspective the body is still experiencing stress as it works through the effects of alcohol consumption.

    Of course, that's just one extreme example. There a great many things that can negatively impact the restorative quality of your sleep.

    Hope that helps.
  • HermanB this reply was very helpful. The alcohol equation makes total sense to me. I find that my stress rate during sleep is even way higher than during my waking hours. I feel that I get good rest. I don’t wake up often during the night. I get about equal amounts of deep sleep as light sleep and sleep anywhere from 6 to 8 hours a night. I could always use more especially during training. Anyway, I am wondering how to get “less stressed” during sleep and recover better. Is this really a number I should worry about? My husband wore the watch one night to sleep. He is a very chill person, it tracked his sleep as restful so I don’t see it being an issue with the watch!
    Thanks for any input! I’ve been wondering about this for awhile.

    My stress levels are orange across the board as I sleep. This has been happening every night since I've owned it, about 6 weeks. I don't drink or do any drugs. Eat healthy, stay active and basically take care of myself. My body battery has never charged as I slept. Only stayed the same or dropped dramatically. I do seem to struggle on the days with a low body batter. Any advice on what could be causing this would be appreciated.

  • Yes, my sleep is invariably all orange or sometimes I have a small blue rest period. It does mean that my stress levels are quite high. I rarely have a drink, walk 6 or so miles a day and do pilates and video workouts. I am very fit and not on any medications. During a restful evening, my stress levels show quite high and show only rare a small period of rest. I would like to understand this better. Most of my sleep registers as light with very little deep sleep. I'm sorry that I can't offer any help to the person who wrote above.

    • Do you have anxiety or feel depleted energetically? Because I do. I'm wondering if its possible sleep apnea myself. I'm not over weight but I suppose that doesn't always matter.

    It's possible you have sleep apnea.

  • I have this problem with my body battery never charging and being stressed during sleep even when getting a full 8 hours of sleep. I attribute it to my PTSD. If you have an anxiety disorder like this then you will be at a heightened level of stress even when you sleep because your body is always in fight or flight mode so you are always stressed. As you can guess, it is really terrible to have. My guess would be you either have a similar disorder or that you are just in a stressful period of your life and it is causing you to be at that heightened level of anxiety that someone with PTSD operates on a daily basis. Try doing yoga or meditation or other methods to calm before you sleep. It helps me even with the anxiety disorder so good chance you can see a drastic improvement if you can get into the right state of mind before sleep. If you feel anxiety that is constant and has no origin basically at all the times every second of every day, you may have a disorder like me and should seek help medically to get to the bottom of it and help improve the symptoms.

  • I have been having the same issue for the last few weeks, and I don't know what is causing it.

  • I've noticed that mine is more orange when I've had caffeine or alcohol that day or in the previous few days. When I go several days without caffeine or alcohol, it is almost all blue when I sleep. Caffeine especially can be tough to let go of, but if you can give it a try, you may see more blue during your sleep. I believe the Garmin stress calculation is related to heart rate variability,  so it makes sense that these substances may be culprits (among a bunch of possibilities like life stress, change in exercise habits, etc).

  • I wouldn't mind seeing this thread re-vitalized with more contemporary understanding of what the body is doing and what the watch sensors are detecting.  I too see considerable amounts of "orange" stress during sleep and apparent companion inability to get my body battery above 75 percent.  These observables make perfect sense on the rare occasions when I have alcohol, but that doesn't explain the trend.  I drink a fair amount of coffee before noon (when my stress level is almost always lowest for the day), but generally steer clear of caffeine sources after noon (no caffeinated beverages and limited chocolate).  I have obstructive sleep apnea, but I [almost always] use a CPAP [currently set one cm of H20 higher than prescribed as an experiment to see if that affects Garmin stress measurement], Not using CPAP hasn't revealed any discernable stress scoring pattern.  I will say I am finding the CPAP mask system a bit annoying and think that it might be arousing me frequently throughout the night.  I am "older" and as predicted, Garmin almost never detects any "deep" sleep. My sleep score is routinely fair or poor, with a randomly-occurring "good" here and there that don't correlate with feeling particularly more refreshed.  I started taking an adrenal gland support supplement, thinking perhaps they are chronically over-worked, but I'd like some doctor to build a credible theory linking my adrenal function to my Garmin stress score.  I'm not particularly stressed from an emotional standpoint, so it almost has to be a malady of the body I'm looking for.  I'd like to go to a doctor to get them to weigh in, but I'm skeptical that many mainstream medical folk have any familiarity with HRV, or even a working knowledge of what stimulates the sympathetic NS or what impairs the parasympathetic NS. Most docs I know react quickly with a recommendation that I just stop looking at my watch.
