Have the same pattern, issue is cortisol/stress, not sounds / etc that happen precisely at night
Built simular things tonwhat Op did (thoug using Oura for sleep tracking, not Garmin)
Result: no statistically significant variations in sounds, CO2 normal etc. Cortisol is what doctors/AI told me first
Yeah, if you continuously wake up around 3am you are anxious/stressed/depressed. Whole article is overthought/engineering mindset nonsense.
