Heart health is more than just your pulse
The resting heart rate is a well-known metric. Yet, on its own, it says little. Only in combination with heart rate variability, sleep, and activity does a realistic picture emerge.
What science recommends
Cardiological guidelines emphasize the importance of regular exercise, good sleep, and stress reduction. Wearables can make these factors visible.
HRV – an underestimated indicator
Heart rate variability shows how well the body can switch between tension and recovery. Low values can indicate stress, lack of sleep, or overexertion.
Why sleep is crucial
Studies show that poor sleep increases cardiovascular risks in the long term. Deep and REM sleep are important recovery phases that modern devices detect automatically.
Digital support in everyday life
Health devices help to record these values continuously – without active intervention. They provide orientation and encourage health-conscious decisions.
