Wearers touch a blue button on the smart band to tell it that they fell anxious or a yellow button if feeling calm.
This data is gathered and fed to a mobile app and online platform.
The gadget also records its wearer鈥檚 activity and sleep patterns to identify any correlations.
The wrist-band is made by health tech start-up Moodbeam. Spencer Group is one of the first businesses to adopt the device and offer it free to any employee that wants to try it.
