I also have around 30% average of REM sleep, however I’m different like other as I don’t suffer with any anxiety or depression. Everyone's body and brain are different but it is cool that we have all these new gadgets to give us some data to look back on while we make changes to improve! I wouldn't put too much stock in strict numbers though, maybe keep a journal of how you are feeling at certain percentages and things you have done to increase sleep quality and most importantly how those changes affect your awake hours. I have always used meditation, though I have kinda fallen out of habit with it lately so I am interested to see how that may improve sleep quality.
I should note that I am a night shift worker (11p -730a 4x/wk) so that affects my sleep a lot, I have found that by taking a sleep supplement with melatonin, magnesium, 5-HTP, and GABA I have seen improvements to increasing my deep sleep (I was previously low as 5%). I also suffered from chronic depression, though right now I am doing pretty good. That's an interesting correlation, my REM sleep is at 30% and Deep sleep at 13% currently. Hi! I also get too much REM and not enough deep sleep. Hope some of my (purely as a patient) sleep knowledge was of some help
Another (slightly worse) suspect is sleep apnea. Vitamin D and Iron are usually the first suspects in my experience. Feeling tired is often a symptom of depression, but it can also be as simple as not having enough of certain vitamins or minerals. Other tips would include seeing your doctor about depression, sleep and/or fatigue if you haven't already. Getting enough sleep and learning de-stress is also important. I have years of sleep issues and daily fatigue behind me (still unresolved), but I had a sleep study last year that came back normal (I still don't fully believe that).Ī good and easy tip for better sleep is to review your sleep hygiene to see if there are rooms for improvement. I almost never check my sleep stages, but your description sounds a lot like me, so I went a couple of weeks back to check and realized that according to Fitbit, my REM and deep sleep are under the range (same range as yours) 90% of the time. You may also want to go back and see if this is a normal reading for you. I wouldn't be too worried about the one percentage point because the striped range is the typical range (simple guideline) for each sleep stage. Disclaimer: I'm not a doctor and if you have any worries, you should take them up with one of those.
