(FORTUNE Magazine) – Sleep trainer Michael Krugman (soundersleep.com) has treated workers at Saatchi & Saatchi, Equitable Life Assurance, the NYPD, and Philip Morris (gee, wonder what keeps them up at night). "Most of the major industrial disasters and accidents like Bhopal, Exxon Valdez, and Chernobyl involved sleep-challenged workers," he says. Janice Revell had a few questions.

Why do people have problems sleeping?

This is an overstimulated society. Companies want employees to be as productive as possible but there's the misapprehension that people work well only when they're hurrying or in a state of hyperarousal. You can't be in that state all day and then just turn it off.

How does your system work?

There are certain slow, gentle rhythmic movements--particularly those involving the eyes, lips, and tongue--that can bring people very quickly to a state of profound repose. Once you're in that state, your mind and body just decide what to do next. If you need sleep, you're going to fall asleep.

How long does it take to master the moves?

Many people respond after one session with me; some need four or five. If you're willing to practice three minutes, three times a day, you usually get great results. That's not a big commitment.
