For Christmas I got a FitBit Alta HR. This model will estimate your sleep stages (light, deep, REM) if you wear it while you sleep. So I have been, and the news hasn’t been all good: it tells me I get a lot less REM than the normal person. I’ve been experimenting with sleep hygiene routines like reducing screen time before bed etc. They seem to help but they also stress me out because frankly, I need that before-bed time to get work done at my computer.
Two mornings ago my cat woke me up early by sitting on my head. It was fifteen minutes until my alarm went off, so I just lay there talking to her.
When I got up and synced my FitBit, it told me I’d been in REM during that time.
Last night it recorded me as being in REM when I was awake and reading.
I understand that sometimes I’m going to be so still that it thinks I’m asleep when I’m not (watching TV while snuggling with my husband is particularly prone to that) but FFS, this isn’t generic “you’re asleep,” this is their super-duper advanced Sleep Stage Reporting and it’s WRONG and it’s been stressing me out.
There are lots of places on the internet where people argue about how surprisingly accurate the HR FitBits are with sleep stages. I call baloney.
