Understanding Health Metrics
Modern wearables and health apps provide a wide range of health data. Metrics such as HRV, VO₂max, sleep quality and resting heart rate help you understand how your body responds to stress, exercise and recovery.
HRV
Heart rate variability reflects stress, recovery and nervous system balance.
Resting Heart Rate
A key indicator of cardiovascular health and fitness.
VO₂max
A measure of aerobic fitness and oxygen uptake capacity.
Sleep Duration
Total sleep time influences recovery, energy and overall health.
Sleep Efficiency
The percentage of time in bed actually spent sleeping.
Sleep Stages
Light sleep, deep sleep and REM sleep are key parts of the sleep cycle.
Stress Level
Physiological signals like HRV and heart rate can indicate stress levels.
Recovery Score
A combined metric showing how well your body has recovered.
