For short trips, readjusting the body’s clock might not seem worth the effort. Jim Waterhouse, a professor of biological rhythms at Liverpool John Moores University in Liverpool, England, says he often recommends that people crossing three time zones or less and only staying three days or less might want to consider maintaining the same sleeping and waking schedule from home rather than trying to shift the body clock. “Keep your watch set to the time at home and act accordingly,” he says.
Great idea. On 3 day, 3 time zone trips or less, just continue to live as if you’re in your home time zone if you can.
