Real-Time Stress

What is Real-Time Stress?

Real-Time Stress is a comprehensive metric calculated by comparing current heart rate data (including HRV) with historical data.
The higher the value, the further your heart rate deviates from its normal range, indicating greater physical stress.

This metric helps identify whether you're under higher-than-usual physical stress or in a relatively relaxed state.

How is Real-Time Stress categorized?

Real-Time Stress is expressed as a percentage, with the following ranges:

• Great：1%-20%
• Normal：20%-60%
• Pay Attention：60%-80%
• Overload：80%-100%

Note: These ranges apply only to waking hours; sleep standards differ.

Is lower Real-Time Stress always better?

No.

Stress comes in two forms: positive (eustress) and negative (distress).

During exercise, elevated stress values are normal and considered positive. This may persist for hours after intense activity.

High stress during rest indicates negative stress, often linked to psychological pressure, fatigue, incomplete recovery, stimulant consumption (e.g., alcohol/caffeine), or illness.
