Expert: Robert deStefano, founder of Sleep Garden (877/475-3376), a Menlo Park, California, company that specializes in audio and visual sleep aids.

Field of study: Sleep as a means to better mental and physical well-being.

His basic philosophy: Stress-induced insomnia is not a disease or illness. You do not need to medicate. The secret is learning how to recalibrate. It takes work to break its vicious cycle, but once you do, you’re good for life.

Most memorable hotel bed: The beds at the Stanford Court hotel (from $179; 415/989-3500) in San Francisco are, forgive the cliché, like sleeping on a cloud.

Favorite quiet retreat: Olema Inn & Restaurant (from $198, including breakfast; 415/663-9559), near Point Reyes. It’s so sweet, especially the rooms up the hill and further from the road. It’s wonderful on a sunny afternoon to sip Champagne and enjoy local oysters on your little garden patio.

Best mellowing warm drinks: Many teas can help you relax. Try “Get Some ZZZ’s” from Republic of Tea ($10 for 36 bags). Look for organic and for simple flavors like chamomile—and, of course, no caffeine!

Next-day remedy for a sleepless night: Avoid the temptation to add extra caffeine. Eat well throughout the day, avoid sugar and fats, and have an early dinner. Don’t try to compensate by going to bed too early. Take a warm bath, listen to relaxing music, then go to bed around your usual time—which, by the way, should be between 10 p.m. and 11 p.m.
