Most employees identify 2:45pm as the start of the post lunch dip.

Nearly half of office workers would willingly swap their lunch break for an afternoon nap - according to recent research. Of the 1000 people surveyed, 46 per cent believed that a nap at lunchtime would improve their productivity in the afternoon.

Just over a quarter believed that it would have a negative effect on their output. Eight per cent of those polled had no opinion either way.

The survey, conducted by Deal Jungle, showed that a sizable majority (63%) believed that office productivity dipped in the afternoon, with 2:45pm being the time most employees identified as the start of the post lunch dip.

Over a third (37%) of those polled were prepared to sacrifice all breaks whatsoever in order to reduce their working hours either in the morning or afternoon.

A spokesperson for Deal Jungle commented: "The idea of an afternoon nap may sound childish, however if it has the potential to increase productivity then it is an option which must be seriously considered.

"Think about it, how many of us religiously take our allotted lunch break? If we were to put aside just 30 minutes for a quick snooze in the corner we would be saving ourselves not only time but also improving our health and wellbeing at work."
