How Does Garmin Measure Stress?

Garmin devices measure stress levels primarily through Heart Rate Variability (HRV) analysis. This sophisticated measurement provides users with valuable insights into their body's stress response throughout the day.

Understanding Heart Rate Variability

Heart Rate Variability refers to the variation in time between consecutive heartbeats. While many people think our hearts beat at a steady rhythm, there are actually tiny variations in the timing between beats. These variations can tell us a lot about our stress levels:

Higher HRV typically indicates lower stress levels
Lower HRV usually suggests higher stress levels

How Garmin Calculates Stress

Garmin devices use their optical heart rate sensor to continuously monitor your heart rate and calculate HRV. The device then processes this data to generate a stress score on a scale of 0-100:

0-25: Resting state
26-50: Low stress
51-75: Medium stress
76-100: High stress

Factors Affecting Stress Measurements

Several factors can influence your Garmin stress readings:

Physical activity
Sleep quality
Emotional state
Caffeine consumption
Alcohol intake
Overall health condition

Using Stress Data

Understanding your stress levels can help you:

Identify stressful periods during your day
Make lifestyle adjustments
Plan recovery time
Improve overall well-being

Remember that while Garmin's stress measurement is a useful tool, it should not be used as a medical diagnostic device. Always consult healthcare professionals for medical advice.
