DL Ep. 10: Loneliness as Deadly as Smoking 15 Cigarettes a Day
In this episode of Dharma Lab, Richie Davidson and Cortland Dahl dive into one of the most startling findings in modern science: that loneliness and social disconnection can be as harmful to our health as smoking fifteen cigarettes a day.
They explore what makes loneliness so toxic—not just for our mental well-being, but for our physical health—and how ancient contemplative wisdom and modern neuroscience converge on the same insight: connection is medicine.
From the biology of stress and resilience to simple daily practices that nurture kindness and belonging, this conversation reveals how small shifts in awareness can rewire the brain for connection—and why doing so may be one of the most important things we can do for ourselves and our world.
