DESCRIPTION: Sleep is an important aspect of animal physiology, with humans spending around 1/3 of their day sleeping. Despite the importance of sleep being poorly understood, how it is regulated has been widely investigated. There are two internal biological mechanisms, circadian rhythm, and sleep-wake homeostasis, which work together to regulate when humans are awake and when they go to sleep. Circadian rhythms are involved with directing an array of bodily functions which fluctuate throughout the day, controlling the timing of sleep by causing sleepiness at night and the tendency to wake in the morning without an alarm. They are based on a roughly 24-hour day and synchronise with environmental cues (light and temperature) as to the actual time of day; however, they can continue even in the absence of environmental cues. Sleep-wake homeostasis on the other hand keeps track of the body’s need for sleep, reminding the body that it must sleep after a certain period of time. It is involved with...
