Sometimes, the way you physically feel may differ from the key insights you get after taking a measurement. And it’s ok.

Heart rate variability (HRV) doesn’t reflect your mood or emotional state. It shows how your heart and nervous system react to what is happening to you.

Many different things can have a bearing on how you feel — from events in your life and diseases affecting your hormone and neurotransmitter levels to caffeine, nicotine, and other substances. You may feel energized when your body needs a break. Or find yourself drained while the energy is still there. This is exactly where HRV measurements are helpful — they show you what your body is really experiencing at the moment.
