Let Them Hit Snooze - More on Teen Sleep Deprivation

More on Teen Sleep Deprivation

In this article in Principal Leadership, Saara Myrene Raappana sums up the accumulating research on the deleterious effect of sleep deprivation on teenagers and reports that only 15 percent of U.S. teens get the recommended minimum of eight and a half hours on school nights. The impact:

  • Athletic performance – Studies of football players, swimmers, and tennis players have shown that getting an ideal amount of sleep improves athletic performance and stamina and reduces fatigue.
  • Attention span – The NYU Sleep Disorders Program has found that inadequate sleep can result in children displaying hyperactivity, inattention, and impulsiveness.
  • Bodily health – Proper sleep is linked to reduced inflammation, healthier weight, better cardiovascular health, and a longer life span.
  • Creativity – The emotional elements of new memories are bolstered during sleep, which may stimulate the creative process, according to a Harvard study.
  • Driver safety – Driving when sleep-deprived is even more dangerous than driving drunk, according to a 2009 report from the National Highway Traffic Safety Administration. One night of insufficient sleep is equivalent to one alcoholic drink.
  • Grades and test scores – Numerous studies have shown that students with impaired or irregular sleep perform more poorly on tests and have lower grades than those who get enough sleep.
  • Memory – Consolidation occurs during sleep, which strengthens memories and helps “practice” skills.
  • Mental health – Sleep reduces stress levels, decreases anxiety, and can play a part in alleviating symptoms of depression. 

There does seem to be a national trend toward later high-school start times: since 2012, high schools in California, Oklahoma, Georgia, and New York have pushed their start times later, joining Connecticut, North Carolina, Kentucky, and Minnesota.

Mentors.net - a Professional Development Resource

Mentors.net was founded in 1995 as a professional development resource for school administrators leading new teacher induction programs. It soon evolved into a destination where both new and student teachers could reflect on their teaching experiences. Now, nearly thirty years later, Mentors.net has taken on a new direction—serving as a platform for beginning teachers, preservice educators, and

other professionals to share their insights and experiences from the early years of teaching, with a focus on integrating artificial intelligence. We invite you to contribute by sharing your experiences in the form of a journal article, story, reflection, or timely tips, especially on how you incorporate AI into your teaching

practice. Submissions may range from a 500-word personal reflection to a 2,000-word article with formal citations.
