We’ve known for several years that unhealthy behaviors are contagious and spread within social networks. But it turns out that healthy behaviors are contagious, too! When someone exercises, the people around them are more likely to do so as well. When someone loses weight, their trusted social network is more likely too also lose weight. This may seem intuitive, but groundbreaking new research is showing us just how powerful these forces are and igniting our imagination about how we can use this knowledge to improve the health of large populations.
