The balance between sleeping and waking is regulated by a process called homeostasis. Induced or perceived lack of sleep is called sleep deprivation. Process S is driven by the depletion of glycogen and accumulation of adenosine in the forebrain that disinhibits the ventrolateral preoptic nucleus, allowing for inhibition of the ascending ...
Process S represents the drive for sleep, increasing during wakefulness and decreasing during sleep until a defined threshold level, while Process C is the oscillator responsible for these levels. When being sleep deprived, homeostatic pressure accumulates to the point that waking functions will be degraded even at the highest circadian drive ...
Sleep hygiene studies use different sets of sleep hygiene recommendations, [15] and the evidence that improving sleep hygiene improves sleep quality is weak and inconclusive as of 2014. [2] Most research on sleep hygiene principles has been conducted in clinical settings, and there is a need for more research on non-clinical populations. [2]
What’s so bad about polyphasic sleep? “Sleep is where all of our recovery happens, and it’s got to be in a row, and it only happens when you get a certain kind of sleep,” says Dr. Pristas.

Sleep plays a vital role in regulating metabolism and appetite. When sleep deprived, the metabolic system will be out of balance, which will ultimately affect the dietary choices people make. Teens who are sleep deprived crave more carbohydrates. Sleep deprivation is a risk factor for obesity among young adults. [7] [medical citation needed]
Since the REM stages typically occur during the second half of sleep, sleeping too little may not allow the body enough time to complete all the REM sleep cycles, per the National Sleep Foundation.
One of the important questions in sleep research is clearly defining the sleep state. This problem arises because sleep was traditionally defined as a state of consciousness and not as a physiological state, [14] [15] thus there was no clear definition of what minimum set of events constitute sleep and distinguish it from other states of partial or no consciousness.
