Explore the anatomical and physiological basis of sleep regulation

Explore the anatomical and physiological basis of sleep regulation and its impact on overall health and well-being. Discuss the neurochemical mechanisms underlying the sleep-wake cycle, including the role of neurotransmitters such as adenosine, serotonin, and gamma-aminobutyric acid (GABA) in promoting sleep onset and maintenance. Additionally, analyze the consequences of sleep deprivation and sleep disorders such as insomnia, obstructive sleep apnea, and narcolepsy on cognitive function, mood regulation, and cardiovascular health, and evaluate evidence-based interventions for optimizing sleep quality and duration.
