"From Anxiety to Exhaustion." A doctor at Pirogov Russian National Research Medical University explained how stress works.
The idea of stress was first formulated in 1936 by Hans Selye. True, at that time Selye understood stress as a natural adaptive reaction of the organism to some irritating factor, while he called the pathological effect of tension on the body "distress." Today, however, the word "stress" is understood by almost everyone to mean precisely the pathological, excessive, exhausting effect on the body. And there is a scientific explanation for this.
This was told to the Uralweb portal by Fyodor Evdokimov, Associate Professor of the Department of Faculty Therapy at the Institute of Motherhood and Childhood of Pirogov University of the Russian Ministry of Health, Candidate of Medical Sciences.
Stress has several stages. The first stage is alarm, where adrenaline and other substances that trigger the adaptation mechanism "work." During the alarm stage a large amount of adrenaline is released into the blood from the adrenal glands. This first stage, essentially, is a protection against the unexpected.
In people with cardiovascular disease, at this initial stage there can indeed be an increase in blood pressure, an increased heart rate, and impaired myocardial perfusion, which will adversely affect health.
The second stage is resistance, when the body adapts to the impact and no longer perceives what happened as a shock. If the stressful influence ceases at this second stage, the body returns to its usual life. If this does not happen, the third stage ensues — exhaustion, or the very distress according to Selye.
At this stage the activity of adaptation hormones decreases, blood pressure and body temperature fall, and lactic acid accumulates in the tissues. The longer the stressor continues in the third phase, the more pronounced the damage to tissues and organs will be, which can ultimately lead to disability and even death.
"What doesn't kill us makes us stronger" and "What the Lord does not do — it's all for the best." These maxims may not lessen the pain of what was endured, but they should help interrupt stress at the adaptation stage.
