If you long for more shut-eye, you’re not alone. The National Sleep Foundation reports that 64 percent of adults frequently experience sleep problems; nearly half wake up during the night. Americans filled almost 59 million sleep-aid prescriptions in 2009, but according to Sheila Kingsbury, ND, chair of botanical medicine at Bastyr University near Seattle, such drugs can compound the problem, causing brain fog, addiction, and side effects like dry mouth and constipation. Moreover, they often fail to get at the root of the problem, be it anxiety, a disrupted sleep cycle, or a nutritional deficiency. “Different causes call for different treatments,” says Jenny Tufenkian, ND, clinical instructor at the National College of Natural Medicine in Portland, Oregon. Here’s a guide to determining which natural remedies may be right for you.
