In all fairness, we also had some identical readings during our pilot testing of blood lactate analyzers today.
More to come in 2025!

Agreed! And the integration with ResearchRabbit is awesome.

Conclusion: Be careful with interpreting HRV-based metrics outside of rest.

Three reasons why your sports watch cannot measure stress
SHARE YOUR SCIENCE: The most crucial element in managing stress is, and will always be, you - how you interact with the world and manage the universal challenges we all face.

Which is likely due to the watch not being able to measure my HRV (and HR) correctly.
In fact, it thinks my HR is 75 bpm, not 136 bpm as my ECG chest strap is suggesting.
Note that measuring HRV correctly is even more difficult than measuring HR.

However, the sensor on the watch can only measure HRV with sufficient accuracy when you're at complete rest.
Example: This is me cycling indoors at 190 W and 135 bpm. My watch thinks I'm at a stress level of 28/100. While I'm exercising!

Among the topics we discussed is the continous measurement of your stress level during the day. According to Garmin, this "measure" is based on your HRV.
