In this insightful conversation, neuroscientist Ben Rein joins Neil deGrasse Tyson to explore the impact of loneliness on the brain and our health. 🧠 Research indicates that social isolation can increase mortality risk by 50%, highlighting that humans, designed as social creatures, experience elevated cortisol levels, the stress hormone, when disconnected from social ties. The discussion underscores the difference between loneliness and social isolation, noting that you can feel lonely even in a crowd if your social needs aren’t met. Additionally, they address modern society’s loneliness epidemic and the potential for drugs like MDMA to foster social connections, which can be helpful but are not a long-term solution. Pets, especially dogs, are mentioned as beneficial companions that can provide the social interactions some people lack. As we face increasing isolation, finding social connections becomes essential for our health and longevity. 🌍 To gain deeper insights into overcoming loneliness, check out Ben Rein’s new book “Why Brains Need Friends”! 📚 By StarTalk
