Imagine this: You’re leisurely going about your day when you meet someone on edge. Immediately, what was once peace and quiet becomes caught up in the stress and dissipates.
If this applies to you, then you’ve just been infected by the virulent stress bug. It may be a figurative expression; nonetheless, science has proven that stress is contagious.
This was the focus of a study conducted by researchers from the Cumming School of Medicine at the University of Calgary. The findings of the study, published in the journal Nature Neuroscience, may help explain specific stress-related conditions, such as incidences where family members of soldiers with post-traumatic stress disorder (PTSD) exhibit similar symptoms – even if they have never been part of the military.
In the study, Dr. Jaideep Bains and his team at the Cumming School of Medicine looked at how stress can be transmitted using pairs of male and female mice. The team took one mouse from each pair away from the other and exposed it to mild stress before returning it to its partner. They found that the neural networks that regulate the brain’s response to stress have changed for both the stressed mouse and its naive partner. Even more interesting was the fact that the networks were both altered similarly.
“There [have] been other literature that shows stress can be transferred — and our study is actually showing the brain is changed by that transferred stress,” according to lead author Toni-Lee Sterley. “The neurons that control the brain’s response to stress showed changes in unstressed partners that were identical to those we measured in the stressed mice.”
Researchers also found that activated neurons release an “alarm pheromone,” in the stressed mouse – which his partner picks up. It then alerts other members of the group.
“What we can begin to think about is whether other people’s experiences or stresses may be changing us in a way that we don’t fully understand,” explained Bains.
Another thing that his group discovered was that the effects of stress disappear in female mice after a social interaction. However, this was not the case in male mice.
The researchers believe that the results of the study may benefit personalized approaches in treating stress disorders in people.
At the end of the day, beating stress isn’t just a personal win: It also affects people close to us and saves them from needless worry.
Here are some simple ways to beat stress naturally.
