Sleep regulation is the process by which the body and brain control the timing and duration of sleep. This process is influenced by various factors, including circadian rhythms, environmental cues, and physiological mechanisms. Research in this area focuses on understanding how these factors interact to regulate sleep, as well as the implications of disruptions in sleep regulation for overall health and functioning. Additionally, studies in this field may explore the role of different neurotransmitters, hormones, and brain regions in the regulation of sleep. Ultimately, this research aims to uncover the underlying mechanisms of sleep regulation and develop strategies to improve sleep quality and duration.
