If our circadian rhythm is pegged to the flow of daylight and dark, and if the pineal gland at the base of our brain is pumping melatonin, signaling it’s nighttime, and if an array of other systems align, our neurons swiftly fall into step.Neurons, some 86 billion of them, are the cells that form the World Wide Web of the brain, communicating with each other via electrical and chemical signals.These half-second bursts, called spindles, indicate that we’ve entered stage 2.

At the same time, our sensory receptors are muffled, and soon we’re asleep.

Scientists call this stage 1, the shallow end of sleep. Then, ascending from deep in the brain, comes a series of electric sparks that zap our cerebral cortex, the pleated gray matter covering the outer layer of the brain, home of language and consciousness.

In our restless, floodlit society, we often think of sleep as an adversary, a state depriving us of productivity and play.

, who gave us light bulbs, said that “sleep is an absurdity, a bad habit.” He believed we’d eventually dispense with it entirely.

We’re not just rotely filing our thoughts—the sleeping brain actively curates which memories to keep and which to toss.

To forestall , the soldiers should remain awake for six to eight hours, according to neuroscientist Gina Poe at the University of California, Los Angeles.

The average American today sleeps less than seven hours a night, about two hours less than a century ago.

This is chiefly due to the proliferation of electric lights, followed by televisions, computers, and smartphones.

Research by her and others suggests that sleeping soon after a major event, before some of the ordeal is mentally resolved, is more likely to turn the experience into long-term memories.

Stage 2 can last up to 50 minutes during the night’s first 90-minute sleep cycle.
