From impaired focus to difficulty concentrating, a video from BuzzFeed shows the impact of sleep deprivation, reports Good.is.

Ever pull an all-nighter to cram for a test or finish an important work project? Sleep deprivation will leave you feeling wrecked the next day and has a major impact on cognitive function as well. According to the video above, courtesy of BuzzFeed, missing one night of sleep leaves you as impaired as having a blood-alcohol concentration of .10. Miss four nights? You’ll start hallucinating, and after six, you’ll fall into a state of psychosis.

Although this video is about extreme sleep deprivation, a large percentage of Americans are losing sleep every night, and it’s affecting their health. In fact, according to the U.S. Centers for Disease Control and Prevention, 30 percent of American adults, or 40.6 million people, are sleeping six or fewer hours a day. Minor sleep loss leads to cognitive problems, weight gain, and mood disorders. Although some see sleep deprivation as the of byproduct great work ethic, it actually lowers job productivity.
