Mayo Clinic Radio: Screen Time As summer vacation rolls on, you might find your children are looking for things to do. They've been to the pool or camp, so what next? Often, their first choice is screen time — watching TV, playing video games or connecting with friends via social media.

The dangers of too much screen time for children can include behavioral and sleep problems, obesity and loss of social skills.
