What matters to a child’s health? Sure, some things are embedded in our genetics. But from the moment we’re born, there are a million different experiences, factors, and choices that contribute — from our neighborhoods and homes, to screen time and family dynamics. There’s also air pollution, neighborhood crime, where we’re born. Health researchers call that stuff “social determinants.” Sometimes, those things can cause stress that lead to sickness. Meanwhile, welcoming and supportive environments can be like winning the “health lottery” for some kids. In this episode, we examine how environments influence kids’ health — their minds and bodies, growth and behavior — and their futures.
