It is considered that stress is an extremely dangerous condition that certainly must be fought. It is worth noting that it is a bit complicated. Stress is essentially an adaptive response that allows us to mobilize the power of our body to threat (stressful) situation. Of course, if you constantly experience stress, our internal reserves are exhausted, and then health problems begin. As in most cases, if we are talking about stress, it is important balance. But can stress be helpful enough to prolong life? Researchers from the University of Michigan believe that Yes.
What is the benefit of stress
As the portal Science Daily, a team of scientists from the US found that stress experienced at an early age increases subsequent resistance to stress in the elderly that does not diminish thereby its negative effects on the body. In this study, the experts concentrated on the point that in the process of stress reactions in the cells accumulates too many free radicals. Free radicals are elements that damage DNA and other internal cell structure, causing their modification and is considered to be one of the causes of aging at the cellular level.

But our body is not stupid and he has methods for fighting free radicals. However, when the cells produce more oxidants and free radicals than the number with which they can handle, and then begins the harmful effects. Studying the species of roundworms called Caenorhabditis elegans, American scientists Ursula Jacob and Daphne Bacopoulou found that worms that made more free radicals due to stress at a young age, lived longer than worms that have not experienced stressful situations.
Researchers have long been wondering what determines the variability of life expectancy, One part is genetics: if your parents live long, then you have a good chance of living longer. But the other part is considered is your space. But this is not true. — scientists say.
By sorting thousands of larvae of round worms, scientists began to grow, divided into several groups according to levels of stress. From those who lived in the “greenhouse conditions” to individuals who are constantly exposed to various “tests”. The authors have identified the most important difference between them is the concentration of the modifier of histones. This compound is sensitive to free radicals arising from stress and its level, laid on the larval stage persists for life. It protects the body from stress. The more, the more stable the body.

If life expectancy is determined solely by genes and environment, we would expect that genetically identical organisms grown under the same conditions, died about the same time, but this is not happening. Some worms live only three days, while the other 20 days. Then the question arises: what, besides genetics and the environment that is causing such a big difference in life expectancy?
When the researchers subjected the whole population of young worms to the impact of stressors, the life expectancy of the entire population increased significantly. Of course, the findings of this study can not absolutely “shift” on people and the required additional studies in this field (the scientists and plan to do). However, have long speculated about the positive impact of stress on life expectancy. And it seems that the first hypotheses are confirmed.
