Stress May be contagious: You can communicate it to others, without even knowing it


New Research Says Stress is contagious If your partner feel stressed, the chances are high that you may suffer stress too, say, researchers, including one of Indian-origin, who have found that stress is contagious.The study, in mice, also showed that stress alters the brain on a cellular level.”Recent studies indicate that stress and emotions can be ‘contagious’. Whether this has lasting consequences on the brain is not known,” said Jaideep Bains, Professor, Physiology, and Pharmacology at the University of Calgary.

The researchers then examined the responses of a specific population of cells, specifically CRH neurons which control the brain’s response to stress, in each mouse, which revealed that networks in the brains of both the stressed mouse and naive partner were altered in the same way.

The team discovered that the activation of these CRH (Corticotropin-releasing hormone) neurons cause the release of a chemical signal, an ‘alarm pheromone’, from the mouse that alerts the partner. The partner who detects the signal can in turn alert additional members of the group.

This propagation of stress signals reveals a key mechanism for transmission of information that may be critical in the formation of social networks in various species, the researchers said. The researchers also suggested that these findings may also be present in humans.

“We readily communicate our stress to others, sometimes without even knowing it. There is even evidence that some symptoms of stress can persist in the family and loved ones of individuals who suffer from PTSD, Bains noted.

The study was published in the journal Nature Neuroscience.
