Dr. Badr comments in WSJ article examining optimal sleep for good health

July 21, 2014

Several sleep studies have found that seven hours is the optimal amount of sleep - not eight, as was long believed - when it comes to certain cognitive and health markers, although many doctors question that conclusion. "I don't think you can overdose on healthy sleep. When you get enough sleep your body will wake you up," said Safwan Badr, chief of the division of pulmonary, critical care and sleep medicine at Wayne State University School of Medicine.
