The Healium Score is the percentage of time that you were more relaxed than when you started the session.
How is it calculated?
When you connect a compatible biofeedback device, such as an EEG headband or a smartwatch, Healium measures your starting baseline. For the EEG headband, this baseline is determined by your high beta brainwaves, while for a smartwatch, it is based on your heart rate.
As you do a Healium session, those signals are constantly measured and compared to your starting baseline. If those measurements indicate you are calmer than your starting baseline, then your Healium Score goes up. Since the Healium Score is a percentage of time, there is a max score of 100.
