We learn for example that living 1 year of daily stress can reduce life expectancy by ... 6 years.
The conclusion leaves on a philosophical note ... But I let you look before discussing it.
Summary:
For over thirty years, neurobiologist Robert Sapolsky has been studying the consequences of stress on primates. Thanks to the analyzes of the cellular and blood samples which he carried out on them, he highlighted that the social position of a monkey in the group conditions its level of stress hormones. Clearly, the most aggressive and cunning males arrive at the top and benefit from all the advantages: females galore, food in abundance and inexhaustible procession of groomers. The rest, subordinates, are subjected to chronic stress evidenced by a higher heart rate and higher blood pressure.
This discovery led another researcher, Professor Michael Marmot, to conduct a large study of 28 public servants over several years. And this study showed that humans are no different from monkeys in this respect: the lower you are, the more stress hormones you produce and the greater the risk of disease. Those in the second row are more threatened than those in the top, and so on down the ladder. A whole string of conditions then appears, from gastric ulcers to cardiovascular problems, from obesity to serious sleep problems, from depression to psychiatric disorders, which directly affect life expectancy.
And the effects of stress do not only have visible consequences: over time, the telomeres, the terminal structure of our chromosomes, are also modified. By studying the genetic heritage of a group of mothers of disabled children, a researcher was able to observe their fraying, the corollary of which is accelerated aging: basically, for each year spent looking after a chronically ill child , we age six years!
Fortunately, this damage does not seem to be irreversible. As long as the causes of stress disappear, telomeres can return to their original shape. Among the remedies warmly recommended by doctors are compassion and concern for others, sociability and mutual aid, but also pleasure and relaxation. Adopting more intelligent social behaviors than those of our cousins, monkeys will one day be within our reach. No ?

Stress is extremely widespread in our modern societies and seems to be watching us at every turn. It ruins our days and prevents us from sleeping at night. Originally, however, the stress was positive: when humans were still living in the savannah, surrounded by wild animals, the stress and the reactions it triggered could save their lives. Simply, these reactions are no longer adapted at all to life in a Western-type civilization. Stress then becomes a trap, a real psychological plague ...
New scientific discoveries reveal how dangerous stress can be; far from being a simple state of mind, stress is a real and quantifiable phenomenon. It can eventually destroy our brain cells, make us fat and even attack our chromosomes. This is shown by several studies.
