Limited screen time for children associated with better cognition

The video discusses recommended guidelines for children's sleep, screen time, and physical activity. A study of 4520 US children revealed that only 5% met all three guidelines, while 41% met at least one. On average, children slept 9.1 hours, had 3.6 hours of screen time, and 3.7 hours of physical activity weekly. Screen time and sleep were strongly linked to cognitive development, with excessive screen time leading to poor development.
