What does work [to remedy jet lag]? “Napping and caffeine, among various solutions,” said Dr. Rosekind. “When I was at NASA, we did a study involving 26-minute naps and we found they boosted performance by 34 percent and alertness by 54 percent. Naps of less than a half-hour work.

“Using a combination of nap and caffeine is better than using them separately, if you can believe it. It takes 15 to 30 minutes for caffeine to kick in. So you do the two together. All it takes is a cup of coffee — not even a pill. By the time the caffeine is working, your nap is over.”
