New Study Shows Lack of Sleep Leads to Permanent Brain Damage
We all know that sleep is one of the best ways to restore our body. For example, when we become sick, we just lie in bed and sleep all day; or after a long day bustling between class, the gym, meetings, and extracurricular activities, our body yearns to fall into a deep slumber to restore itself to its peak state. Recently, it was published that the reason sleep is so restorative is because while we sleep, cerebrospinal fluid flows more efficiently through the brain, essentially “clearing” the brain of any metabolic waste products that build up during the day (for more on this, refer to the December 9th blog post). However, just as we all understand that great feeling of satisfaction that comes after the so rarely obtained 8-9 hour sleep cycle (yes, young college-aged adults should ideally be getting 8-9 hours of sleep a night), we also can all relate to the groggy, confused, cognitively impaired state that comes after the all-night cramming and three hours of sleep, and before the double espresso from Starbucks. Until recently, this chronic state of unrest considered normal by college students, shift workers, and truck drivers, wasn’t thought to have any long lasting damage; it was considered common knowledge that catching up on sleep during weekends or vacations made up for the hours of sleep lost during finals week. However, a new study published on March 18th in the Journal of Neuroscience refutes this; the study, out of University of Pennsylvania’s Perelman School of Medicine, shows that chronic sleep loss may be much more destructive than previously thought, leading to permanent cell damage and neuronal death.
