“Budging the circadian clock” after leaping several time zones is hard – but a sleep doctor says it can be done.
When he got to Yorkshire, England, on a recent trip, Robert Rosenberg began one of his standard routines: He laced up his sneakers and took an afternoon jog.
Rosenberg was, in reality, doing more than getting fresh air and exercise; he was adjusting his body to the local time zone, which was eight hours ahead of his home in Arizona. Rosenberg, a doctor of sleep medicine who runs the Sleep Disorders Center of Prescott Valley, in Prescott, Ariz., was beating jet lag with exercise and exposure to afternoon sunlight. Both are elemental to overcoming jet lag, he said.
