Getting rejected hurts depressed people for longer, U-M/Stony Brook/UIC study finds — due to the lack of a natural pain & stress-reducing chemical
The brains of healthy individuals (left column) released natural opioids during social rejection (colored spots) that may help to reduce negative emotions associated with rejection. In contrast, study participants with depression (right column) did not release nearly as many opioids, which may contribute to a lingering depressed mood following rejection.
