“Sleep timing is controlled by the circadian clock, by homeostasis and in humans, within certain bounds, by willed behavior. The circadian clock, an inner time-keeping, temperature-fluctuating, enzyme-controlling device, works in tandem with adenosine, a neurotransmitter which inhibits many of the bodily processes that are associated with wakefulness. Adenosine is created over the course of the day; high levels of adenosine lead to sleepiness. In diurnal animals, sleepiness occurs as the circadian element causes the release of the hormone melatonin and a gradual decrease in core body temperature. The timing is affected by one’s chronotype. It is the circadian rhythm which determines the ideal timing of a correctly structured and restorative sleep episode.[5]“
