Recommended Amount of Sleep for a Healthy Adult: A Joint Consensus Statement of the American Academy
Sleep is essential for optimal health. The American Academy of Sleep Medicine (AASM) and Sleep Research Society (SRS) developed a consensus recommendation for the amount of sleep needed to promote optimal health in adults, using a modified RAND Appropriateness Method process. The recommendation is summarized here. A manuscript detailing the conference proceedings and evidence supporting the final recommendation statement will be published in SLEEP and the Journal of Clinical Sleep Medicine.

health. Sleeping less than 7 hours per night on a regular basis is associated with adverse
health outcomes, including weight gain and obesity, diabetes, hypertension, heart
