Brains Over 50 Need 6 to 9 Hours Sleep

They found that across the board, people sleeping less than six hours and more than nine hours had significantly lower cognitive scores compared to others. Two more factoids to think about as you doze off: Women reported longer sleep durations than men in all countries except Russia and Mexico. Men and women in South Africa slept longer than in any other country. The least sleep hours for both sexes occurred in India. Read more from the University of Oregon.
