Stress is your body’s natural response to physical or mental challenges. While brief surges can sharpen focus, chronic stress can erode health and performance.

By comparing your current heart rate variability (HRV) and heart rate (HR) to your personal baselines - and filtering out periods of physical exercise - Sonar helps you recognise the moments, habits, and environments that dial stress up or down.Read more
