The research area of sleep, or sleep science, is the study of the physiological and psychological processes involved in sleep and its impact on health, cognition, and overall well-being. Researchers in this field may investigate various aspects of sleep, such as the stages of sleep, sleep disorders, circadian rhythms, the impact of sleep deprivation, and the role of sleep in memory consolidation and learning. Studies in this area may involve measurements such as brain activity, heart rate, and hormonal levels during sleep, as well as behavioral assessments and interventions to improve sleep quality. Overall, research in sleep science aims to better understand the mechanisms underlying sleep and its importance for overall health and functioning.
