And right now, I believe I'll have a nap: Revealed: Why our brains get so tired in the afternoon
It’s known as the dreaded 2:30 feeling.
You’ve had your eight hours of sleep, a very productive morning and a healthy lunch - but as the afternoon hits you start to fall into a post-lunch slump.
Feeling drowsy after lunch is completely natural, according to Dr Fiona Kerr, a neuro specialist from the University of Adelaide, who explains that humans are “built for two sleeps a day”.
. . .
She adds the slump in the afternoon occurs because our bodies are effectively “programmed to nap” at that time.
“A major reason for this is that human beings are biphasic (physically designed for two sleeps a day), with two major bodily rhythms (homeostatic sleep drive and circadian arousal) which pull us in different directions in terms of staying awake or sleeping, but they fascinatingly align in the middle of the day to create a ‘nap zone’.
