17.24 nap detection working very bad

Miky over 1 year ago

Installed this morning at 6am the new software.

It detected a nap from 7:37am to 8:24am when I was sitting in my car scrolling the phone before starting work!

Don't want nap detection, how can I disable it?

All,

I definitely understand the desire for the ability to delete falsely detected naps.

If you would like this option, or see many false naps on your device, please reach out to Garmin Product Support

Yes I do see companies communicating via their forum. Quite a lot companies do this.

For info, if you look in GC / Health Stats / Body Battery.... Naps show as Factors at the botto of the screen.

It adds to your body battery total for the day.

Now I saw it, thank you!

Recording naps I'm not having wouldn't be a problem, I can just turn off the glance, but it messes up my recovery time and body battery.

I had a cheap Amazfit watch years ago that did nap detection perfectly. Garmin struggles with the strangest stuff.

Basically, these stats are based on sleep tracking, which isn’t accurate, nap tracking, which isn’t accurate and heart rate tracking. Again, which isn’t accurate.

I just read an article where they compared the sensor of a fenix 6 (the same as on a forerunner 955/965) with chest streaps and it’s not looking great for the garmin.

Mine says I took a nap when I was watching a movie. I want to be able t9 turn this feature off because it is rubbish. Actually the sleep detection is pretty damn poor IMO.

I didn't read the article completely and went straight to the Conclusion. This is something known already, that's why it is suggested to use the chest strap for cardio workouts with better precision (but still not perfect).

"Chest-based ECG devices are preferred to wrist-based PPG devices due to superior HR accuracy over a range of exercise intensities, with the OMNI device demonstrating equal, if not superior, performance to other commercial ECG monitors. Additionally, wrist-based PPG devices are significantly affected by exercise intensity as they underestimate HR at low intensities and overestimate HR at high intensities."

While working on the PC, my FR955 detects a nap. Thank God my boss won't see this information... What nonsense.

Does it have something to do with the Resting HR setting? I work on the computer daily and since I upgraded it never detected a nap by mistake. I'm just asking guessing because I haven't seen information on what it considers or how it works.

I see the same problem on my FR255 with the latest. And it did something similar in the early days with detecting a sleep interval in the middle of the day under similar conditions, before I had the sleep schedule set. I'm not sure the actual detection has changed much, just the new accounting of naps? It only has the HR sensor and accelerometer as input. But from the HR sensor, it also produces other derivative metrics like respiration rate and HRV, so Garmin only knows how each may factor into the sleep/nap heuristics.

I've wondered what sets apart the folks who like this feature from those of us who get lots of false detections. I know I am a very restful, physically calm person as a baseline. When I sit to read, or watch TV, or work on my computer, I am very still. And I think my restful breathing is pretty steady and deep, with a daily average around 13 or 14 breaths per minute. Normally, if I think about my breathing, I lapse into something more like "square breathing" (without actual counting).

I took a calcium blocker for about a month to treat chilblains, and it was funny to see how the watch reacted. I don't have high blood pressure, rather I was at risk for low pressure with each dose. I described them as "panic attacks in a pill" for the way they almost felt like a vagus nerve reaction. I usually had to sit down and try to ride out the first 15 minutes. The watch would either show high stress or sometimes add high intensity minutes to my daily total.
