The Kalevala Smart Rings are the simplest solution to measure stress and recovery. By reading the signals of the autonomous nervous system the ring gives accurate, real-time data on fluctuating stress levels. The Moodmetric index is calculated from the electrodermal activity (EDA) of your skin. Electrodermal activity is a very sensitive indicator of emotional and cognitive stress. The Moodmetric index tells about the activation of your sympathetic nervous system on a scale of 1 to 100. A good target for the Moodmetric daily average level is around 50.
The Kalevala Smart Rings are developed in collaboration with the Finnish company Moodmetric. The ring is connected to the free Moodmetric app, which makes it simple to analyze stress and the need for recovery.
