hello I woke at 9.20am and my Fitbit had fallen off my wrist in bed (faulty strap) I synced it and found very high heart rates at 7am when asleep - 161bpm then minutes later down to 91bpm then no HR for an hour and then up to 194bpm. why was this? I am not sure if it’s accurate or if it wasn’t on wrist at this point? Could lying on it cause this? Would it register high HR if loose on my wrist? Looking for reassurance please, not sure if this has happened to others? It has spiked like this off my wrist in a car. Thank you
