Stephanie,who lives in California,is preparing to compete in track and field at the Olympics in London.She plans to arrive in London

Question

Quizplus · Accepted Answer

Stephanie should arrive in London several weeks before competing because her peripheral clocks in her muscles and lungs take longer than her suprachiasmatic nucleus (SCN) to adjust to a new time zone. This is because her SCN, which is responsible for regulating the body's sleep-wake cycle, adjusts quickly to a new time zone, while peripheral clocks in other parts of the body adjust more slowly. By arriving several weeks early, she can give her body enough time to fully adapt to the new time zone and optimize her athletic performance.
