Sleep on a Schedule

For surgeons, sleep is a responsibility—you've got lives in your hands. But sleep also helps keep you healthy. One study found that people who slept six hours or less per night on average were around four times more likely to catch a cold. I follow a strict routine, going to bed and waking up at the same times every day. When your body gets used to a schedule, it will find a natural rhythm, making it easier to fall asleep. I also allow myself a nap if I need one: A 20-minute catnap helps me stay alert for the rest of the day without making it hard to doze off that night.
