UK researchers have found that people with lots of friends have a higher pain tolerance. Why? Because being social releases the body’s natural painkillers: endorphins. These pleasure-boosting chemicals not only promote bonding, but they have a painkilling effect stronger than morphine. It’s long been thought that social interactions trigger endorphins, which bind to opioid receptors in the brain to up pain tolerance – and this research proves social types can handle pain better than lone wolves. That’s pain relief we’re onboard with!
