In Understanding Jet Lag, host Harith Iskander explains how jet lag occurs when a person’s internal clock doesn’t match the external time of a new location. The brain’s oscillator cells in the hypothalamus, which help regulate our sleep-wake cycles, struggle to adjust quickly. Traveling east can be especially difficult because it shortens the body’s natural circadian cycle, while flying west allows for more gradual adjustment. This video is excerpted from BBC’s Got Science?, a science magazine series that explores and explains science in everyday life.
