Once we would brag of not needing very much of it. Now deep slumber is a coveted state achieved with gadgets, apps, gizmos and classes.
“Sleep today is a measure of success, a skill to be cultivated and nourished.” TIM ROBBINS
At M.I.T.’s Media Lab, the digital futurist playground, David Rose is investigating swaddling, bedtime stories and hammocks, as well as lavender oil and cocoons. Mr. Rose, a researcher, an inventor-entrepreneur and the author of “Enchanted Objects: Design, Human Desire and the Internet of Things,” and his colleagues have been road-testing weighted blankets to induce a swaddling sensation and listening to recordings of Icelandic fairy tales — all research into an ideal sleep environment that may culminate in a nap pod, or, as he said, “some new furniture form.”
“For me, it’s a swinging bed on a screened porch in northwestern Wisconsin,” he said. “You can hear the loons and the wind through the fir trees, and there’s the weight of 10 blankets on top of me because it’s a cold night. We’re trying a bunch of interventions.”
Meanwhile, at the University of California, Berkeley, Matthew P. Walker, a professor of neuroscience and psychology and the director of the Sleep and Neuroimaging Laboratory there, is working on direct current stimulation as a cure for sleeplessness in the aging brain. Dr. Walker is also sifting through the millions of hours of human sleep data he has received from Sense, a delicately lovely polycarbonate globe designed to look like the National Stadium in Beijing that measures air quality and other intangibles in your bedroom, then suggests tweaks to help you sleep better.
“I’ve got a mission,” he said. “I want to reunite humanity with the sleep it is so bereft of.” Sense is the first product made by Hello Inc., a technology company started by James Proud, a British entrepreneur, for which Dr. Walker is the chief scientist.
In Paris, Hugo Mercier, a computer science engineer, has invested in sound waves. He has raised over $10 million to create a headband that uses them to induce sleep. The product, called Dreem, has been beta-tested on 500 people (out of a pool of 6,500 applicants, Mr. Mercier said) and will be ready for sale this summer.
That is when Ben Olsen, an Australian entrepreneur, hopes to introduce Thim, a gadget you wear on your finger that uses sound to startle you awake every three minutes for an hour, just before you go to sleep. Sleep disruptions, apparently, can cure sleep disruption (and Mr. Olsen, like all good sleep entrepreneurs, has the research to prove it). It is his second sleep contraption. His first, the Re-Timer, a pair of goggles fitted with tiny green-blue lights that shine back into your eyes, aims to reset your body’s clock. He said that since 2012, he had sold 30,000 pairs in 40 countries.
For years, studies upon studies have shown how bad sleep weakens the immune system, impairs learning and memory, contributes to depression and other mood and mental disorders, as well as obesity, diabetes, cancer and an early death. (Sedated sleep — hello Ambien — has been shown to be as deleterious as poor sleep.)
