Why We Need a Nap after Lunch?

A quick ten minute nap after lunch helps you keep fresh and energetic for rest of the day. But do you know why we don’t feel a similar urge after our breakfast ? Sleep researchers at University of Manchester have some answers:

It is the nerve cells in the brain that keep us alert when the body needs fuel [read food]. But once we eat and that hunger is sated, the nerve cells are also turned off. Glucose – the sugar found in foods – stops these cells from producing signals to keep people awake.

According to researchers, we do not get tired after eating breakfast because we are on the rising phase of our circadian rhythm.
