In the quiet hours between dusk and dawn, researchers at UC Davis have found something families have long overlooked: for adolescents navigating anxiety, depression, or psychotic-like disturbances, sleep is not merely rest but a buffer between inner struggle and outer consequence.

Households may increase spending on sleep-related products (mattresses, pillows, sleep tracking devices) and services (sleep clinics, therapy). Parents may reduce pressure on children regarding screen time and exercise, potentially decreasing spending on certain tech and fitness products. Increased demand for mental health services and sleep interventions could raise healthcare costs for families.
Schools may implement sleep-focused wellness programs and adjust start times. Healthcare providers may prioritize sleep assessment in adolescent mental health treatment. Policymakers may regulate marketing of sleep-disrupting technologies to minors. Insurance coverage for sleep interventions and mental health services may expand. Educational curricula may incorporate sleep hygiene education.
