Sleep has been a persistent problem for me in my adult life whether it is not being able to fall asleep due to racing thoughts or an inability to get quality sleep. About a year ago, I bought a smart watch that tracks sleep. According to the manufacturer, studies have shown that the device is about 70% accurate in terms of its accuracy in sleep data that it provides. Two main trends I have seen in my sleep data is that I am almost always short on REM sleep and I tend to wake up a lot during the night. Often times I don't even recall waking up especially if it is just a few minutes, but other times when I am awake longer, I usually remember. From what I have read, REM sleep is usually the sleep stage where dreaming occurs and is important in brain function. I know sleep problems tend to be common among those of us on the spectrum so I am curious if anyone else has similar experiences in not getting enough REM sleep or with waking up during the night. I know smart watches are not medical devices but I suspect that persistent trends in data are accurate. Lacking REM sleep also seems to make sense since those of us on the spectrum usually experience cognitive challenges such as information processing disorder and rigid thinking. I wonder if any studies have dug into this further. I have changed some habits which have resulted in improved sleep, but getting consistent quality sleep continues to be elusive. I notice big difference in my mood and my level of functioning based on the quality of my sleep.
