Wakefulness

Wakefulness is the state of being awake and alert, the condition of being conscious, or not asleep. It involves the capacity to perceive, think, and respond to stimuli from the environment. This encompasses a range from light alertness to intense vigilance. Maintaining wakefulness relies on complex neurological processes regulating the sleep-wake cycle, influenced by circadian rhythms and external cues like light and social activity. Impairments in wakefulness can result in decreased cognitive performance, compromised physical function, and emotional disregulation.
