Neuroscientist Ben Rein, author of 'Why Brains Need Friends,' exposes the dangers of isolation, explaining how it triggers chronic inflammation and negatively impacts health. He champions social connection as vital for well-being, detailing its neurochemical benefits and offering practical ways to foster deeper human bonds in our 'post-interaction world.'
Neuroscientist Ben Rein, a vocal critic of online 'junk neuroscience,' emphasizes the importance of accurate scientific communication. His new book, 'Why Brains Need Friends: The Neuroscience of Social Connection,' addresses the critical role of social interaction in an increasingly 'post-interaction world.' Rein presents compelling evidence that isolation is profoundly detrimental to health, citing studies showing lonely mice suffer worse strokes and isolated humans face significantly higher mortality rates. He explains that isolation triggers an evolutionary stress response, leading to chronic cortisol release and sustained inflammation, which damages organs and impairs healing. Conversely, social connection promotes the release of oxytocin, an anti-inflammatory hormone that suppresses stress and aids healing, while also stimulating dopamine (for reward) and serotonin (for mood). Despite these benefits, humans often underestimate the positive impact of socialising due to inherent social anxiety and the 'liking gap.' Rein highlights that online interactions are a 'pale imitation' of real connection, lacking vital social cues like facial expressions and body language, which can lead to 'virtual disengagement' and hostility. He suggests 'upgrading' interactions (e.g., meeting in person over video calls), considering pets (which boost oxytocin), and using emojis online to convey emotion. Rein also cautions against alcohol as a social lubricant, noting its negative impact on empathy. His ultimate ambition is to provide a clear, individual incentive for social connection, not only for personal health but to foster a more compassionate and less fractured society.
