I have been awake about half the night for years. I check on the clock regularly to know when I was awake, just to have an idea of how much energy I have the next day. (I have ME/CVS and long-covid, so this is important to me).
- Unfortunatly most of my time awake is registered as 'light sleep'.
- I had 4 dreams and no recorded rem-sleep. (dreams only occur in rem-sleep).
- I got up halfway the night and 1 hour later went back to bed. All within my set sleep-time. But it only registered the first half of the night as sleep. The is no 'resume to sleep' button.
How to get more accurate sleep data?
I shaved the hair on my wrist just to make sure hair is not preventing accurate readings.
This is really disappointing. The sleep and body-battery data is the whole reason I bought this device.
