The Stress Is Contagious, A New Study Proves

The stress transmitted by others would have the same effects on your brain as our own stress, according to the results of a study published in the medical journal Nature Neuroscience. These findings were obtained from research on mice and the study also showed that the effects of stress are different in males and females.

Recent studies revealed that stress can be contagious

Scientists at the University of Calgary, in Canada, studied the stress effects in couples of male and female mice.

“Stress-related brain changes underlie many mental illnesses, including post-traumatic stress disorder (PTSD), anxiety disorders, and depression. Recent studies indicate that stress and emotions can be contagious, but it is unclear if this has lasting consequences for the brain,” explained Jaideep Bains, a professor and a researcher at the Department of Physiology And Pharmacology.

Stress is contagious, indeed, a new study clearly concludes

The study has been conducted on pairs of mice. The scientists removed one mouse from each pair and exposed it to mild stress before putting it back next to its partner. They then examined the responses of a specific population of cells in each mouse.

Researchers focused mostly on the CRH neurons which are known to control the brain’s response to stress. They observed that the CRH neurons networks in the brains of the regular mice were acting in the exact same way with the CRH networks in the brains of the stressed mice.

This study also highlighted a difference in behavior between females and males. It has been noticed that female mice managed the stress better than males.

“We easily communicate our stress to others, sometimes without even knowing it, and it is even proven that certain symptoms of stress can persist in the family and loved ones of people suffering from PTSD,” the scientists reported. The fact that the stress is contagious is the key to building social connections.
