When you are calm and relaxed, brain waves have unique characteristics, and studies have shown a link between increased alpha wave energy and relaxation. [1][2][3][4]
The waves will be captured by Flowtime sensors and the algorithm which is built based on large data analyzing will measure how relaxed you are and generate an index to show that.
This relaxation, not the same as the relaxed feeling of your body, reflects the mental relaxation degree. When the value is high, the brain is relaxed but also alert, while when it's low, the brain is nervous or anxious.
By deep breathing and closing eyes, your relaxation level will go up.
<aside> 📌 Brainwave frequency varies from person to person. The algorithm needs to set a baseline for you. To have a accurate baseline, please minimize your face movements like blinking, gritting teeth or moving eyes within 30s after you start to meditate.
