Rob Knight, the academic superstar who is leading the Center for Microbiome Innovation at UC San Diego, says it’s important for kids to get dirty! He explains that exposing children to natural bacteria in the environment trains their immune systems how to respond to foreign threats. So, resist that urge to sterilize everything kids touch because you’re not helping. Instead, let them roll around in the grass, swim in rivers and the ocean, and cuddle with dogs. You might wince at the contact, but the germs they meet will make them stronger in the long run.
