Teens today are facing a perfect storm of mental-health challenges, increased academic pressures, and tech overload, all set against the backdrop of chronic sleep-deprivation. While we all know sleep is essential for teens’ well-being, it is far too easy to downplay the risks, or understand what’s at stake when they are regularly skipping sleep in order to get everything done. Advocate, educator, and journalist, Lisa L. Lewis, who helped spark the first law in the nation requiring healthy school start times, addresses these questions and more. Lewis offers insights into how we can make changes at home and in our schools– and also build a common understanding of why teen sleep matters. Lewis has written for The Washington Post, The NY Times, The Atlantic, TIME, the Los Angeles Times, Slate, and Your Teen, among others.
