>>The wristband tracks the movement of your wrist through the >>night, which it can use to analyze your sleep patterns.
How is wrist movement co-related to sleep patterns ? Is there any scientific study / data out there that explain the co-relation ?
Co-relation of pulse rhythm is more obvious - cant say the same about wrist movement.
Anyone care to explain ?
