Cricketer Shubman Gill was recently spotted wearing a 'Temple' on his forehead.
The pre-orders for this wellness device, which is not on the market yet, are expected to begin next week.
As per reports, the device, though not certified as a medical tool, detects microvascular blood flow and tissue changes.
It also generates a metric named 'Entropy,' which updates physiological strain, stress and load on our cognitive, physical and thermal systems.
