"He was wearing a Garmin watch on the day of the run with his heart rate on it. It all seemed fine, he was living a very healthy life. There were no indications really."

“That interval-type training is good,” he said, “where your heart rate goes up for a time then comes back down.”

But monitors that measured her brainwaves, heart rate, blood pressure, and oxygen levels showed no biological cause for her suffering.

Further studies showed how important this reconciling behavior is for primate health, reducing indicators of stress like an elevated heart rate.

Omega Chen purchased a Garmin watch to track his heart rate and other metrics when he exercised, but it also measured things like his resting heart rate and “sleep score” every day and night.
