How do I disable naps?

Unfortunately there is no way to turn this feature off. The false naps is a significant issue for Garmin even when we delete them the data doesn't really go away it just turns into "rest" and still impacts all of the the metrics like body battery and recovery. I hate seeing that little note that my recovery was boosted by my nap even after I have deleted it, I didn't actually nap - I was at work!!

We currently use forerunner 965 and tactix 7 pro in our household. We have not had any false nap recordings yet.
Is your data given in Connect such as RHR, HRmax, etc. correct?

Yes my data is correct and I also know how to wear a HR sensor.  This is a Garmin issue, not a user issue. They are aware that this is an issue for many users, the solution was to add a delete option rather than actually fix the problem. 

It works amazingly well for me and my family.

I often get naps recorded on my 965 from sitting watch tv, ridiculous you can't delete or turn of this feature 

How to delete naps? I found it one time, but can't find the option again.

You have to go into sleep coach, scroll down to the nap and click it and you should be able to delete it but only on the day it happens.
