Incorrect tracking of fragmented sleep

I'm male, sixty, and partially disabled by a sleep disorder that's related to narcolepsy type 2. I don't have the My Own Private Idaho plot device problem, I get two to five minutes warning. Since someone always brings it up, I do NOT have sleep apnea. My BMI is 27 and I logged 96 miles in the last thirty days on my Fitbit, till the poor thing died in its sleep a couple days ago.

Today was my second full day and the device really goofed on sleep. The system had me getting 7:32 of sleep between 2139 and 0801, ignoring three solid hours of wakefulness, and mistakenly crediting me with a twelve minute nap in the middle of that three hours. The twelve minutes was NOT an episode, I'm well aware of when they happen, and recovery time is a minimum of about ninety minutes.

Then, adding to the confusion, I laid down from about 1200 to 1400. There's a clear activity gap that correlates with reduced heart rate during that time, but the device didn't pick that up either. The missing data is right, the band was charging.

My resting heart rate is consistently about twenty points higher than would be expected for someone my age and weight. Google tells me there's a way to adjust the zones, but I have not yet figured out how to do that. Am I going to be able to tune this thing so it can track my reality?

 

  • Here's another failure to detect sleep. I laid down at 12:07 today and woke up at 15:05. The red underline shows a period of no motion and heart rate around 80, which is what passes for resting in my condition. Is this going to improve over time? If I'm not getting accurate wake/sleep information that's a real problem.
