Why Does My Stress Drop Upon Waking?

Looking for any insight here...the image below is what is the norm for myself.  My stress overnight is constantly orange (normally low stress) and as soon as I wake up it drops down into the blue.  

  • I don't drink alcohol.
  • I go to bed at the same time each night.
  • Do not eat within three hours of bed.
  • No caffeine after 10am each morning.  
  • No noticeable tiredness during the day.

I will say that I have what I consider to be a fairly high resting HR...it has always been between 60 and 70 no matter my fitness level.  I can be running 200 miles per month and my Resting HR is still 60+, but it really is about that if a true resting while sleeping or awake just sitting at my desk or walking around.

I guess I get confused on how my "stress" just suddenly drops when I wake up.  Is it that Garmin uses a different method for determining stress when awake versus sleep?  Basically since my resting HR and such is so similar when sleeping and awake it thinks I am too stressed when sleeping, but then suddenly thinks I am having a restful day when I am awake?

I know you all are not doctors or medical experts, but just thought it would be interested to see if anyone has experienced anything similar or had any insight.  Really things like stress level, body battery, etc. have been useless for myself as Garmin seems to always think I have terrible sleep, etc.

    I can‘t confirm that.
    My stress graph shows the complete opposite of yours. During sleep, stress is low. If I had a hard training or hard day, it takes some time to sink. Usually the lowest stress is shortly before waking up.

    After rising, stress is higher, especially after eating and drinking coffee. And after training of course.
    Same on FR 255 and before two years on FR 245.

    I can be running 200 miles per month and my Resting HR is still 60+

    Maybe that is part of the explanation?

    I run no more than 100 miles a month in average and my resting HR is 48, says Garmin (can be sometimes confirmed manually during boring meetings in Homeoffice Wink).

    I don‘t want to worry you, but maybe you should talk to a doctor about your discoveries regarding stress at night and resting HR. Could be, that you have some kind of irregularity (whether that would be dangerous would be pure speculation).

  • Thanks...my point on the 200 miles per month was really that it doesn't matter.  I am not running near that now...just a point that my fitness level doesn't seem to impact my resting HR one way or another...based on years of observation.  I also agree that maybe I do need to talk to a doctor about this specifically...just seems weird that something changes when I am awake.

  • My stress level is typically 10-15 while sleeping. If I sit down and relax while awake, the stress level is typically around 20.

  • If you will discuss that behavior we need your acute load 4 week graph and your BMI at least.
