AsapScience recently released a couple of short videos that could fit well in middle school and high school health courses. What If You Stopped Sleeping? explains the effects of sleep deprivation as well as the effects of sleeping too much. What If You Stopped Going Outsides? explains why humans need to spend time in sunlight and the effects of not getting outside often enough. Both videos are embedded below. AsapScience includes links to the references used in the production of the videos. Those links are included below the videos.
