While We Sleep, Our Mind Goes on an Amazing Journey: Part 2 (From the August 2018 issue of National Geographic magazine)

Wile, the seven-year-old son of photographer Magnus Wennman, watches cartoons on his iPad— a modern bedtime ritual for some. The stimulation may drive off sleep, but so does the backlit screen: Light at night inhibits the production of melatonin, the hormone that helps regulate our daily biological rhythms.
 

Around 350 B.C., Aristotle wrote an essay, “On Sleep and Sleeplessness,” wondering just what we were doing and why. For the next 2,300 years no one had a good answer.Aristotle_Altemps_Inv8575

In 1924 German psychiatrist Hans Berger invented the electroencephalograph, which records electrical activity in the brain, and the study of sleep shifted from philosophy to science.

It’s only in the past few decades, though, as imaging machines have allowed ever deeper glimpses of the brain’s inner workings, that we’ve approached a convincing answer to Aristotle.

Everything we’ve learned about sleep has emphasized its importance to our mental and physical health. Our sleep-wake pattern is a central feature of human biology—an adaptation to life on a spinning planet, with its endless wheel of day and night.

The 2017 Nobel Prize in medicine was awarded to three scientists who, in the 1980s and 1990s, identified the molecular clock inside our cells that aims to keep us in sync with the sun. When this circadian rhythm breaks down, recent research has shown, we are at increased risk for illnesses such as diabetes, heart disease, and dementia.

Yet an imbalance between lifestyle and sun cycle has become epidemic. “It seems as if we are now living in a worldwide test of the negative consequences of sleep deprivation,” says Robert Stickgold, director of the Center for Sleep and Cognition at Harvard Medical School.

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

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

A full night’s sleep now feels as rare and old-fashioned as a handwritten letter. We all seem to cut corners, fighting insomnia through sleeping pills, guzzling coffee to slap away yawns, ignoring the intricate journey we’re designed to take each evening. On a good night, we cycle four or five times through several stages of sleep, each with distinct qualities and purpose—a serpentine, surreal descent into an alternative world.

At The Alaska Sleep Clinic, our highly trained staff of sleep specialists has helped diagnose and treat tens of thousands of Alaskans over the years suffering from sleep disorders.  We understand that a good night's sleep is critical to people's health and happiness, and we are committed to providing quality service in the treatment of a variety of sleep disorders.
