It can be both physical exertion and psychological shock: work deadlines, relationship problems, illness, or even positive events that change the usual rhythm of life. In moderation, stress can be beneficial - it mobilizes strength, improves concentration.

But with prolonged exposure, cortisol levels remain constantly high \u2014 and this suppresses the production of white blood cells, reducing the body&#039;s ability to fight viruses and bacteria. Therefore, people who are often nervous or live in a state of constant anxiety get sick more often, recover more slowly, and may have exacerbations of chronic diseases.<\/p>\n<h3 class=\"\" data-start=\"2321\" data-end=\"2371\"><strong>Can stress cause chronic diseases?<\/strong><\/h3>\n<p class=\"\" data-start=\"2373\" data-end=\"2722\">Yes.

All of these are not immediate consequences, but the result of long-term effects on hormonal and metabolic changes in the body.
