- The human sleep-wake cycle is regulated by melatonin. The synthesis of melatonin is regulated by light exposure (Figure 1). The human body typically develops a sleep-wake rhythm that does not respond quickly to change. Long-term exposure to extended periods of bright light after sunset is most likely to affect a person in which of the following ways? a) Melatonin synthesis will be increased, and the person will quickly fall asleep. b) Melatonin synthesis will be inhibited, and the person will have difficulty sleeping. c) Melatonin synthesis will be inhibited, and the person will quickly fall asleep. d) Melatonin synthesis will be increased, and the entire sleep-wake cycle will be shifted by several hours.arrow_forwardList three possible functions of melatonin.arrow_forwardDo people with seasonal affective disorder secrete more or less melatonin?arrow_forward
