Is the FitBit accurate if I have Central Sleep Apnea?

The FitBit is indicating I get low REM, but I seem to dream a fair amount. I also have RBD events about once a month. I don't take any medication since my RBD events are rarely anything more than vocalizing or a little leg movement.

@pg3t   In answer to your first question, Fitbit doesn't have any current way to monitor either central or obstructive sleep apnea.  In answer to your second question, I am not an expert on sleep disorders.  My internet search tells me that RBD is a sleep disorder where people move during dreaming. Fitbit's Help article on sleep stages makes it sound like the sleep stage algorithm depends on the "not moving" part of REM sleep to put you in REM stage sleep.  Everything I read suggests that a Fitbit will underestimate your REM sleep.

I think you should talk with you doctor if you have other concerns.

That makes sense! Thanks!
