Research has shown negative associations between screen time, particularly television viewing, and the development of physical and cognitive abilities. Additionally, screen time has been linked to obesity, sleep problems, depression, and anxiety .
The study shows that in adults aged 18 – 25, excessive screen time causes thinning of the cerebral cortex, the brain’s outermost layer responsible for processing memory and cognitive functions, such as decision-making and problem-solving.
