The National Sleep Foundation released the results of a world-class study that took more than two years of research to complete — an update to our most-cited guidelines on how much sleep you really need at each age. The panelists participated in a rigorous scientific process that included reviewing over current scientific publications and voting on how much sleep is appropriate throughout the lifespan.
