According to the survey of American Psychological Association, the average stress levels in the United States alone increased from 4.9 to 5.1 in 2015. The main reasons for stressful experiences or the demands link to stress include employment, money, work, relationships, and situations such a threat to the well-being of the individual, according to Medical News Today.
In some instances, stress could be transmitted to another person and could make the person in stressful experience too. A report suggests that the family members of some of the soldiers diagnosed with post-traumatic stress disorder (PTSD) had also seen signs and symptoms of PTSD even though they did not serve in the military.
A new study to be published in the Nature Neuroscience in March 2018 indicates that stress transmitted to other people could alter the brain in the same way as the real stressed person. The scientists from the University of Calgary led the research.
