Your guidance mostly says to take your daily hrv mins after waking up well I've been taking my the second I wake up and then dose off while it gets my reading then the alarm sound wakes me again is this a good way to establish my hrv I'm usually in the low to mid 90's. Problem is I've taken my reading while not half asleep altho it was still within 30 mins of waking up and the number is usually relatively lower...
