    Want to get some sleep and boost job performance by 34 percent?” Take a 26-minute nap,” says Sara Mednick, Ph.D., research scientist at the University of California at San Diego and author of Take a Nap! Change Your Life. Studies show that one nap of up to 90 minutes between the hours of 1:00 and 4:00 P.M. will reduce your sleep debt, invigorate your day, boost your job performance, and not affect night sleep, says Dr. Mednick. “To start, lie down at the same time every day for 20 minutes without the expectation of falling asleep,” she says. “That way, you’re teaching your body that it’s okay to relax in the middle of the day.” Eventually your body will believe you, and you’ll doze off. Set your watch or cell phone to wake you up — and feel free to expand the time to sleep. Finding a place to sleep can be tricky. Your car is one place, outside under a tree in a crime-free park is another. Or if you’re in a large city, check out the sleep pods some businesses rent out specifically for naps. But what about your job? “If you can a take 20-minute break to run to Starbucks for coffee,” says Dr. Mednick, “you can find 20 minutes for a nap. “If your employer is dubious about the idea, send them to Dr. Mednick. She’ll show him or her the NASA studies demonstrating that napping gives us a mental edge.

    Work It.

    “Exercise improves sleep as effectively as benzodiazepines in some studies,” reports Kalyanakrishnan Ramakrishnan, M.D., an associate professor at the University of Oklahoma Health Sciences Center. On average it reduces the time it takes to get to sleep by 12 minutes, and it increases total sleep time by 42 minutes. And it doesn’t take much. Studies at the University of Arizona show that walking six blocks at a normal pace during the day significantly improves sleep at night for women. Scientists suspect that exercise sets your biological clock into a consistent wake/sleep pattern, or it may boost the brain’s production of serotonin, a neurochemical that encourages sleep. Just make sure you finish your walk at least two hours before bed. Any later and the energizing effect of the activity can actually keep you up.
