Smartwatch-derived exercise metrics as predictors of early hypertension: a…

Your smartwatch is tracking more than just steps; it measures your body's stress level (HRV) and how much you move. If you have lower HRV and less intense exercise, you are signaling your body that it might be running into trouble with blood pressure.

What key smartwatch-derived metrics were found to be independently associated with an increased risk of developing hypertension over a 12-month period?

A) Higher resting heart rate and increased time spent in moderate-to-vigorous physical activity.
B) Lower heart rate variability (HRV), less physical activity, and higher body mass index (BMI).
C) Higher heart rate variability and greater physical activity.
D) Only resting heart rate was a significant predictor of future hypertension.

The Lab Notebook

Scientists tracked 230 people using their smartwatches for 12 months to see if activity and heart metrics predicted future high blood pressure.

They found that people who later developed hypertension had lower heart rate variability (HRV) and less time engaging in vigorous exercise.

Lower HRV and less activity together were the biggest risk factors, suggesting your body's regulation and movement are key early warning signs.
