Sleep Deficit

Staff report, The Hidden Costs of Sleep Deficits, Association for Psychological Science, December 1, 2017

Hidden Costs

Science has produced a strong body of evidence showing how lack of sleep impairs not only a variety of bodily functions, but also cognitive processes such as memory and executive control.

“There does not seem to be one major organ within the body, or process within the brain, that isn’t optimally enhanced by sleep (and detrimentally impaired when we don’t get enough),” says Matthew P. Walker, a cognitive psychologist who heads the University of California, Berkeley’s (UCB) Sleep and Neuroimaging Lab, in his book Why we sleep: Unlocking the power of sleep and dreams.

Through the WI Lens

Many high achievers see sleep as a complete waste of time, but a spate of new books and academic articles have recently shown that nothing could be further from the truth. A lack of sleep not only impairs a variety of bodily functions, but also negatively affects cognitive processes such as memory and executive control.

As one leading academic quoted in the article says: “There does not seem to be one major organ within the body, or process within the brain, that isn’t optimally enhanced by sleep (and detrimentally impaired when we don’t get enough).” This helps understand why the quality of sleep is becoming such a critical offering within the hospitality industry, well beyond the boundaries of luxury hotels. More and more, customers base their decisions on where to stay depending on this. A spate of technological solutions (to prepare for the night, to control noise emissions in the room, etc.) is developing around that offering.
