Why at least 7 hours of sleep is essential for brain health

The University of Utah's article "Why At Least 7 Hours of sleep Is Essential for Brain Health" emphasizes the critical role of sufficient sleep in maintaining overall health, particularly brain function. It highlights that sleep facilitates the brain's restoration and repair processes, including the clearance of toxins via the glymphatic system. Adequate sleep is also vital for memory consolidation, integrating new information into long-term memory, and enhancing cognitive performance. Chronic sleep deprivation is linked to serious health issues such as obesity, hypertension, type 2 diabetes, stroke, neurodegenerative disorders, depression, and impaired stress-management.Prioritizing at least seven hours of quality sleep each night is crucial for brain health and cognitive performance. Adopting good sleep hygiene practices—such as maintaining a consistent sleep schedule, creating a restful environment, and limiting exposure to screens before bedtime—can support this goal. Given the University of Utah's reputable standing and the evidence presented, these recommendations are credible and practical for individuals seeking to enhance their brain health.
