What stress is

Stress is your body’s physical or mental response to a demand, whether it’s a one-off or keeps happening over time [1]. Short bursts are a normal part of life. Your heart rate and HRV tend to shift when you’re under pressure [2], which is why a band on your wrist can reflect it.

Make roomto recover

Seeing your calm periods matters as much as the spikes. Look at when you were relaxed, like a walk, a quiet evening or a good night’s sleep, and do more of it.

Stressquestions

Is this a mental-health test?

No. It shows physical stress levels for wellness, not a diagnosis. If stress feels overwhelming, speak to your GP [1].

What’s the Energy Score?

One number combining the energy you spent with the energy sleep put back.

Do I need to log anything?

No. It’s tracked in the background.
