The Atlantic: The coronavirus can cause insomnia and long-term changes in our nervous systems. But sleep could also be a key to ending the pandemic.
A central function of sleep is maintaining proper channels of cellular communication in the brain. Sleep is sometimes likened to a sort of anti-inflammatory cleansing process; it removes waste products that accumulate during a day of firing. Without sleep, those by-products accumulate and impair communication (just as seems to be happening in some people with post-COVID-19 encephalomyelitis). “In the early stages of COVID-19, you feel extremely tired,” says Michelle Miller, a sleep-medicine professor at the University of Warwick in the U.K. Essentially, your body is telling you it needs sleep. But as the infection goes on, Miller explains, people find that they often can’t sleep, and the problems with communication compound one another.theatlantic.com
