Sleep Health: The Under-Rated Determinant of Brain Health

Abstract

This is a  review of sleep health as an often-undervalued determinant of brain health. It implores current research on the intricate relationship between sleep and cognitive function, emotional stability, and the prevention of neurological disorders. Neglecting sleep not only compromises daily functioning but poses long-term risks to neurological health, including an increased vulnerability to neurodegenerative diseases, mental health disorders, and other systemic diseases. Sleep health measurement involves assessing various sleep domains that are measurable and independently associated with overall well-being. They include sleep regularity, satisfaction, alertness, timing, efficiency, and duration (RU SATED). Optimal sleep health could be achieved by maintaining consistent sleep schedules, creating a conducive sleep environment, and addressing relevant lifestyle factors. The undervalued impact of sleep health on brain health can be improved by raising public awareness of the importance of sleep, integrating sleep education into the school curricula at different levels, and advocating for policies that prioritize sleep. The above recommendations could lead to profound improvements in individual and societal well-being and lasting benefits for cognitive vitality and overall health. This would culminate in the transformation of societal attitudes toward sleep and elevate its status as a cornerstone of brain health.
