Garmin Venu 2S stress levels


i have a garmin venu 2s - latest 5.27 firmware
two things i noticed

1) during sleep there are incredible stress levels more than 70%
    but all other factors are "excellent"
    how do you detect stress at these levels ?
    could it be that the way of waering it makes a difference ?
2) every morning there is a 30 second blackout where the display would not go active
    especially after wake up


  • hi

    i watched it closely and it seems that 0.5cm movement of the watch on my write make a real
    difference in stress levels - not so much for the heart rate tough.
    how can that be possible ??
    i can't glue my watch to my wrist
    and which readings are the correct ones ??
