Stress is also characterized by its stages of development, which were described as early as 1936 by Hans Sellier.
Anxiety.
Resistance.
Exhaustion.
At first, the person is just nervous, not noticing that his body is experiencing a heavy psychological and emotional load, then symptoms are manifested more clearly, and the body begins to fight. During this period, outbursts of anger and severe mood swings are possible. At the last stage, the person is apathetic and quickly gets tired. Depressive states are possible, and you constantly want to sleep.
Positive and negative effects of stress on the modern human body
The mechanisms of stress and its effect on the human body have been studied in detail and are quite complex: they are connected with our hormonal, nervous and vascular systems. What pleases one, makes another suffer. In addition, and everyone's reaction to stress is different. One blushes, the second turns pale, the third eats nonstop, the fourth slim.
Everyone needs stress in small amounts. The positive effect of a little stress is that it makes you think, look for a way out of the situation, motivates you to solve the problem. In addition, the positive effect of overstimulation on the body includes the acceleration of all organs and systems (for example, the acceleration of metabolism, blood circulation and the release of hormones that help regulate nervous tension).
But life today is oversaturated with stress tension, which accumulates in the body and manifests itself in a number of adverse effects. The adverse effects of severe stress can be very different for certain people, we can name just a few results that are most commonly seen in most patients who have undergone a nervous shock.
For example, the psychological or emotional turmoil experienced can result in a weakening of the immune system as well as the GI tract, heart, blood vessels and endocrine system. This can lead to diseases such as angina, hypertension, heart attack, gastritis, ulcers, colitis, cholelithiasis, insomnia, and diabetes.
The effects of constant stress on the nervous system and its effects on the body
The effects of severe stress on the nervous system can cause neuroses, depression and apathy. During a shock, a person loses a lot of nerve cells, the brain works in an increased mode, and the endocrine glands produce an excessive amount of hormones that regulate psychological stress (glucocorticoids).
Accordingly, when the body has managed to relieve the tension and overcome the disease, it goes into economy mode. Because of the subsequent economizing production of endorphin and oxytocin, the consequence for the body of the experienced stress is withdrawal, apathy, irritability.
In such cases, doctors recommend consuming as many foods as possible that stimulate the production of "joy hormones" (hard cheese, liver, bitter chocolate), as well as spending as much time as possible with loved ones and out in the fresh air.
The effects of stress on a person's health can also affect the musculoskeletal system. For example, due to the fact that during stress, the body causes excessive amounts of glucocorticoids that do not have time to be absorbed. After relieving the tension, they seem to "wander" around the body, doing it only harm - contributing to the breakdown of nucleic acids, thereby weakening the muscles and causing the risk of dystrophy.
Osteoporosis can also be a consequence of constant (chronic) stress. Those very "unclaimed" glucocorticoids interfere with calcium absorption. This leads to thinning of the bone tissue. This disease is especially common in women.
It can also have stressful effects on the skin, such as preventing the renewal of fibroblasts (connective tissue cells). This causes the skin to become sensitive to irritants, small wounds to heal worse and pimples and inflammation to occur more often.
The main signs of stress and the human body's response to frequent symptoms
The main signs and frequent symptoms of stress are: pain in the head and neck area, heart, abdomen; increased blood pressure; feeling of "lump in the throat", shortness of breath, "interception" of the voice; sleep disorders, depression, physical weakness, headache, fatigue, unwillingness to do anything, reduced concentration, memory problems and reduced speed of thought, making study or work difficult.
Another symptom and body reaction to stress may be lack of interest in others, even best friends, family and friends; often there are nervous tics and compulsive habits: lip biting, nail biting, etc.; constant guilt, nervousness, anxiety; inadequate reaction to minor problems; appetite disorders - from its absence to an increased sense of hunger; sexual disorders.
A sick person's body reaction to stress can be delayed. It is the body's repeated reaction to a strong nervous shock (death of a loved one, a disaster experienced).
It manifests itself in several weeks or months after the shock (within 2 weeks to six months). In this case, the person may have dreams about the experience, fall into a stupor, and may be tormented by constant memories and even substitute reality. Such a person most often avoids actions that can cause memories of the unpleasant event.
