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 ...
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 ...

Teens who are sleep deprived crave more carbohydrates. Sleep deprivation is a risk factor for obesity among young adults. [7] [medical citation needed]
Poor sleep can disrupt hormones involved in appetite regulation, which can trigger food cravings that may impede weight loss goals and increase the risk of obesity. millann/Istockphoto Steps to ...
“A lower sleep efficiency likely needs improvement, since it could indicate that someone is not sleeping well, has poor sleep habits, or may have a medical condition that interferes with healthy ...
REM sleep is considered closer to wakefulness and is characterized by rapid eye movement and muscle atonia. NREM is considered to be deep sleep (the deepest part of NREM is called slow wave sleep), and is characterized by lack of prominent eye movement, or muscle paralysis. Especially during non-REM sleep, the brain uses significantly less ...
In addition, alcohol causes fragmented sleep and suppresses REM sleep, which plays a role in helping your brain process and consolidate new information and helps ensure better mental concentration ...
Poor sleep quality is defined as the individual not reaching stage 3 or delta sleep which has restorative properties. [28] Major depression leads to alterations in the function of the hypothalamic–pituitary–adrenal axis, causing excessive release of cortisol which can lead to poor sleep quality.
