Study author Brent Coker, from the University of Melbourne said ‘workplace internet leisure browsing,’ or WILB, helped to sharpen workers’ concentration.

‘People need to zone out for a bit to get back their concentration,’ he said.

‘Short and unobtrusive breaks, such as a quick surf of the internet, enables the mind to rest itself, leading to a higher total net concentration for a days’ work, and as a result, increased productivity.’
