Affecting an estimated one-third of the population, insomnia can lead to significant short- and long-term health effects. Insomnia isn't just about fatigue; it can increase the risk of chronic ...
Insomnia and wake-time sleepiness are related to misalignment between the timing of a non-standard wake–sleep schedule and the endogenous circadian propensity for sleep and wake. In addition to circadian misalignment, attempted sleep at unusual times can be interrupted by noise, social obligations, and other factors.
REM sleep deprivation causes an increase in noradrenaline (which incidentally causes the person sleep deprived to be stressed) due to the neurons in the locus coeruleus producing it not ceasing to do so, which causes an increase in the activity of the Na⁺/K⁺-ATPase pump, which itself activates the intrinsic pathway of apoptosis [41] and ...

Accumulated and continuous short-term sleep deficit has been shown to increase and intensify psychophysiological reactions in humans to emotional stimuli. [5] The amygdala plays a strong functional role in the expression of negative emotions such as fear, and, through its anatomical connections with the medial prefrontal cortex (mPFC), has an important function in the subjective suppression of ...
