In positive psychology, ‘flow’, also known as ‘the zone’, is the mental state of operation in which a person performing an activity is fully immersed in a feeling of energised focus, full involvement, and enjoyment in the process of the activity. In essence, flow is characterized by complete absorption in what one does.

Named by Mihály Csíkszentmihályi, the concept has been widely referenced across a variety of fields (and has an especially big recognition in occupational therapy), though the concept has existed for thousands of years under other guises, notably in some Eastern religions.

Achieving flow is often colloquially referred to as being ‘in the zone’
