), which positions them as part of a companywide effort to "support employee well-being," according to a spokesperson.
Some U.S. companies are waking up to the benefits of keeping workers alert. It started in industries such as aviation, trucking, and hospitals, where avoiding careless mistakes is a matter of life and death. Now, as news spreads about the toll fatigue takes on job performance, other industries are climbing aboard, teaching workers how to sleep better at night, shortening work shifts, and setting up napping rooms in corporate offices.
While the trend may fly in the face of America's hyperactive work ethic, there's a growing body of evidence that naps help. At Bombardier Aerospace, a leading maker of small aircraft such as the Learjet, internal research shows pilots who employed strategies to fight off drowsiness performed better than fatigued pilots on cockpit tasks such as responding to radio calls. Tired pilots sometimes fell into "microsleeps"—zoning out for a few seconds, unaware, and thus reacting to events more slowly. "Your brain shuts off, and you can't control it," says Robert W. Agostino, director of flight operations for Bombardier's business aircraft unit.
How does this translate to desk jobs? Just as a drowsy pilot is more likely to miss a radio call, a stock trader whose eyelids are drooping may have trouble pouncing on as many transactions as usual. "People think they're fine. They're not," says Dr. Mark Rosekind, president of Alertness Solutions, a Cupertino (Calif.) consulting company that trains executives in simple techniques for improving alertness at work.
Among Rosekind's tips: get more strategic about how you consume coffee. You'll get the maximum mental boost if you drink a cup one half hour before an important meeting or other business event. Sitting in a brightly lit room for just 15 minutes helps, too, as does exercise. And nap, of course. You won't necessarily lose if you snooze. By Arlene Weintraub
