This Is Your Brain On Exercise

Human beings evolved to move. Our bodies, including our brains, were fine-tuned for endurance activities over millennia of stalking and chasing down prey. “We’ve engineered that out of our lives now,� says Charles Hillman, a psychology professor at Northeastern University who has spent decades studying the link between exercise and cognition. The toll our relatively new sedentary lifestyle takes on our bodies is clear: For the first time in U.S. history, younger generations are expected to live shorter, unhealthier lives than their parents.

While the myriad ways exercise can shape our bodies are well known, researchers have long suspected the same might be true of the brain. Decades of research have gone into examining the effect of exercise on attention, memory, and visual sensitivity, according to Richard Maddock, a professor of psychiatry at the University of California, Davis. “There is a very consistent finding that the brain works better after exercise,� Maddock says. But why that is has been harder to figure out.

The brain works better after a nap as well.

The brain while working needs lots of energy and raw materials
(amino-acids, glucose etc) to produce the electric currents,
neurotransmitters, memory proteins etc.
The amino acids come from precurser proteins ( such as Amyloid Precurser
Protein), are very chemically reactive and therefore and must be used
immediately for producing useful and functional proteins, otherwise they
can clump together in sticky tangled masses - the beta-amyloid
implicated in Alzheimers's disease.
So we must stay active to produce more useful protein and reduce the
production of bad proteins.
Also, when we sleep, the brain volume shrinks by about 15% and thus
opens up lymphatics between the brain cells nerves, allowing lymph to
flush through and cleanse the brain of harmful metobolites, including
perhaps beta-amyloid. For this to work well we really need several hours
of unbroken uninterrupted sleep per night.
Working muscles also use up and produce a lot of protein.

On the very rare occasions that I've had a kip during the day, I woke
up feeling like dirt.
I am also one of the few that only needs about 4/5 hours sleep a night.

You probably slept too long. After 20 or 30 mins you go into a deeper level of sleep and take longer to recover full awakeness.

Possibly.
