Why we love it
When we are fully immersed in an activity and lose track of time, we call this ‘flow’ (also known as being ‘in the zone’).
Flow is highly correlated with happiness because it lifts us from our emotions and helps us stay present (be mindful). People who experience this state regularly often develop other positive traits such as increased concentration, self-esteem and performance.
In order for a flow state to occur, the activity should be seen as voluntary, enjoyable and absorbing but not too challenging.
