BodyLogicMD physician Dr. Bruce Thomas was recently featured in an ABC news segment discussing sleep and what you can do to get more of it. According to the report, studies show that 75 percent of U.S. adults aren’t getting the sleep they need. How much is enough? According to Dr. Thomas, adults should be getting somewhere between 7 and 9 hours of sleep each night. And those of us who don’t get enough sleep have a higher risk of obesity, substance abuse and diabetes.
