Screen time (Wikipedia)

Screen time is the amount of time spent using a device with a screen such as a smartphone, computer, television, video game console, or even a tablet. The concept is under significant research with related concepts in digital media use and mental health. Screen time is correlated with mental and physical harm in child development. The positive or negative health effects of screen time are influenced by levels and content of exposure. To prevent harmful exposure to screen time, some governments have placed regulations on its usage.
