A pilot flies regularly between Japan and California. He also flies the San Francisco to Los Angeles route in California. The pilot will experience the greatest symptoms of jet lag after flying

Question

Quizplus · Accepted Answer

Jet lag is more pronounced when flying eastward, like from Japan to California, due to the direction's effect on the body's internal clock, making it harder to adjust to the time difference.  Traveling eastward creates greater jet lag than traveling westward because your biological clock is more easily extended than shortened (it is easier to stay awake longer than to fall asleep sooner). The longer trip also requires passing through more time zones, another variable that strongly affects jet lag.
