Adolescents who spent more time doing screen-based activities such as gaming, social messaging, TV watching, or web surfing were more likely to develop symptoms of insomnia and, eventually, depression, according to a study presented at the annual meeting of the Associated Professional Sleep Societies. The findings also show that gaming was more strongly linked to depressive symptoms than messaging.
