Let Them. — According to decades of research, having friendships and making connections is not optional. It’s essential for your physical health. Your friendships are actually part of your immune system. In this episode of The Mel Robbins Podcast, Kasley Killam, Harvard-trained friendship expert and researcher on social connection explains why staying connected is one of the most important (and underrated) pillars of health. Kasley explains how loneliness triggers stress and inflammation and how supportive relationships do the opposite. They calm your system and protect your health. In one study, people who felt more supported and who received more hugs were less likely to get sick after being exposed to a cold virus. And if they did happen to get sick, their symptoms were milder. This conversation raises the stakes on friendship and will prove to you why social health is the missing key to living a longer, healthier, and happier life.
