Sleep Physiology
Sleep is a condition of reduced muscle movement in the body. Awareness about the surroundings is reduced at the time of sleep. The body stays mildly responsive or non-responsive to external stimuli. The sleep-wake cycle is controlled by the circadian rhy…

Summary Introduction

To determine:

The affect of darkness and light on melatonin secretion.

Concept introduction:

Melatonin is a hormone which is naturally produced in the body by the pineal gland. The pineal gland secretes melatonin in sync with our circadian rhythms. Melatonin’s primary function in the body is to regulate the sleep wake cycle.

What is the relationship between melatonin and sleep?
If you travel across several time zones to the east and want to use melatonin to help reset your circadian rhythm, at what time of day should you take it? What if you travel west?
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.
