A new paper published in the journal Brain Health warns that excessive screen time can lead to permanent changes in children's brains, affecting their development and future skills. The authors introduce the term 'criticome' to describe how sensory experiences and social interactions during childhood are critical for shaping who we become. Dr. Julio Licinio, a coauthor of the study, highlights that the developmental window extends from birth to 25 years, during which the brain is particularly malleable. The study raises concerns about how screens, which provide intense stimulation, can diminish children's interest in traditional play and social interactions, essential for developing social and motor skills. Additionally, screens contribute to physical health issues, including obesity, as children often eat while using devices. The researchers urge parents to limit screen time and encourage real-world activities, emphasizing that it is not too late to make changes. They suggest creating a structured plan to transition children away from screens, promoting offline engagement through activities like sports, arts, and socialization.
