Humans, like all animals, need sleep, along with food, water and oxygen, to survive. For humans sleep is a vital indicator of overall health and well-being. We spend up to one-third of our lives asleep, and the overall state of our “ sleep health ” remains an essential question throughout our lifespan.
Most of us know that getting a good night’s sleep is important, but too few of us actually make those eight or so hours between the sheets a priority. For many of us with sleep debt , we’ve forgotten what “being really, truly rested” feels like.
To further complicate matters, stimulants like coffee and energy drinks, alarm clocks, and external lights—including those from electronic devices—interferes with our “ circadian rhythm ” or natural sleep/wake cycle.
Sleep needs vary across ages and are especially impacted by lifestyle and health. To determine how much sleep you need, it’s important to assess not only where you fall on the “sleep needs spectrum,” but also to examine what lifestyle factors are affecting the quality and quantity of your sleep such as work schedules and stress.
Eighteen leading scientists and researchers came together to form the National Sleep Foundation’s expert panel tasked with updating the official recommendations. The panelists included six sleep specialists and representatives from leading organizations including the American Academy of Pediatrics, American Association of Anatomists, American College of Chest Physicians, American Congress of Obstetricians and Gynecologists, American Geriatrics Society, American Neurological Association, American Physiological Society, American Psychiatric Association, American Thoracic Society, Gerontological Society of America, Human Anatomy and Physiology Society, and Society for Research in Human Development. The panelists participated in a rigorous scientific process that included reviewing over 300 current scientific publications and voting on how much sleep is appropriate throughout the lifespan.
“Millions of individuals trust the National Sleep Foundation for its sleep duration recommendations. As the voice for sleep health it is the NSF’s responsibility to make sure that our recommendations are supported by the most rigorous science,” says Charles Czeisler, MD, PhD, chairman of the board of the National Sleep Foundation and chief of sleep medicine at Brigham and Women’s Hospital, “Individuals, particularly parents, rely on us for this information.” “The NSF has committed to regularly reviewing and providing scientifically rigorous recommendations,” says Max Hirshkowitz, PhD, Chair of the National Sleep Foundation Scientific Advisory Council. “The public can be confident that these recommendations represent the best guidance for sleep duration and health.”
The panel revised the recommended sleep ranges for all six children and teen age groups. A summary of the new recommendations includes:
