Resistance to stress: new scientific research
NewsThey say that " all diseases are caused by nerves." Indeed, the consequences of stress can be a wide variety of diseases. Every day the pace of life increases, our potential opportunities, and, consequently, our needs, increase. In this regard, a modern person can experience a lot of fears that cause an increase in stress levels.
Today, the topic of stress and mental health is very relevant. Research shows that exposure to stressful factors, ranging from physical violence to social conflict, significantly increases the risk of mental disorders, such as depression or post-traumatic stress disorder (PTSD). However, it has been observed that people react differently to the same stressors: some recover quickly, others remain depressed for a long time. Researchers are studying this issue, as well as evaluating the development of long-term effects of individual exposure to stress.
What's new in science?
In the work of Valentina Bonnefil of the Center for Advanced Research (ASRC) and her colleagues, it was shown that oligodendrocytes, which form myelin sheaths in the central nervous system, are key factors determining the impact of stress.
Experiments were carried out on animals. The mice in the experimental group were exposed to social damage (contact with the aggressor), after which they were divided into groups of "susceptible" and "resistant". Individuals in the group of" susceptible " mice avoided social contact. It was found that different degrees of resistance to stress were associated with thinning of myelin fibers. This, in turn, led to a lack of adaptation to stress.
Resistance to stress can result from active coping strategies, rather than passive inaction, defined as a lack of adaptive response. One possibility of the formation of new myelin as a coping strategy is associated with increased neural activity in "resistant" mice in the neurons of the prefrontal cortex after social damage. Research continues.
How to prevent it?
Our responses are often driven by the experiences of our ancestors, which demonstrates the importance of maintaining mental health across all generations. Oddly enough, but a well-known way to prevent stress that really works is to lead a healthy lifestyle (proper nutrition, good sleep and timely rest) — something that we can already do to improve the level of resistance to stress.
