CNN (5/2, Hunt) reports research indicates that “around seven hours of sleep is the ideal night’s rest, with insufficient and excessive sleep associated with a reduced ability to pay attention, remember and learn new things, solve problems and make decisions,” investigators concluded after analyzing “data from almost 500,000 adults ages 38 to 73 who were part of the UK Biobank – a long-term, government-backed health study. Participants were asked about their sleep patterns, mental health and well-being, and took part in a series of cognitive tests.” The study also revealed that “seven hours of slumber was…linked with better mental health, with people experiencing more symptoms of anxiety and depression and worse overall well-being if they reported sleeping for longer or shorter stints.” The findings (PDF) were published online in the journal Nature Aging.
