Light pollution ruins teen sleep and may contribute to mental disorders, study says

Blocking indoor light to keep your body in sleep mode is one of the first things any sleep expert will tell you to do for better sleep. Now, you may want to use light-blocking curtains at your bedroom windows as well -- especially for any children in your home. Research has long studied the association between indoor artificial light and mental health, but few studies have looked at the impact of outdoor artificial light, especially in teens, making this the first study of its kind, the authors said, with "potentially long-term implications for mental and physical health." "Although environmental light exposure is only one factor in a more complex network of influences on sleep and behavior, it is likely to be an important target for prevention and interventions in adolescent health," said co-author Kathleen Merikangas, a senior investigator and chief of the Genetic Epidemiology Research Branch at the National Institute of Mental Health, in a statement.
