Sleep quality identified as key driver for academic and mental health

Research from UC Davis Health indicates that sleep quality is a primary driver of academic performance and social relationships in adolescents, often outweighing factors such as diet, physical activity, and screen time. A study published in Psychological Medicine, utilizing data from the Adolescent Brain Cognitive Development (ABCD) project, found that sleep quality significantly correlates with mental health outcomes. Specifically, sleep quality explained 36.3% of the association between anxiety and poor academic functioning, and 18.5% in cases of depression.

Clinical neurophysiologist Javier Albares emphasizes that sleep should be treated as a fundamental pillar of health alongside nutrition and exercise. He notes that while much focus is placed on physical training and mental preparation in high-performance sectors like elite sports, sleep is frequently neglected. Albares warns that professionals, students, and athletes often sacrifice sleep to increase productivity, which ultimately leads to diminished performance and increased injury risks.
