The American Health Association concluded that stress is the cause of as much as 60 percent of all diseases. Although many feel its disastrous consequences, few people actually know what the mechanism of stress's impact on the body looks like.
Experts have now tried to explain it and concluded that in acute stress, the sympathetic part of the vegetative nervous system and the core of the adrenal gland are activated, from which adrenaline is secreted into the blood. It is a hormone of urgency and vigilance in animals and humans, which prepares the body for active and aggressive reaction.
The reaction to stressors always involves the appearance of unpleasant emotions, stimulation of the sympathetic or parasympathetic and secretion of stress hormones. All of this together represents an "emergency state" in the body. Regardless of the body's response, active or passive, the usual psychophysical balance is disturbed. Such a condition, if it is too intense or is repeated many times in succession, can lead to symptoms of psychological and physical suffering and damage to certain organs and organ systems.
In some chronic stress conditions, too much cortisol and too much adrenaline are secreted. Excess adrenaline negatively affects the cardiovascular system and cerebrovascular system, and excess cortisol negatively affects immunity, skin, joints, digestive organs and brain.
The brain is the most sensitive, so the researchers, among other things, mostly dealt with the effects of stress on this organ. French scientists have proven that stress makes people irritable. This is what is seen at first glance, but what is not known is that then chemical changes occur in the brain, by preventing the connection of certain neurons. Unfortunately, some changes can be permanent.
Researchers have also found that long-term stress impairs the brain's ability to remember and learn. The volume of gray matter responsible for emotions, self-control and normal psychological functioning decreases. Over time, serious difficulties arise in concentration and the ability to deal with one's own emotions.
Reactions
1. The organism does not distinguish a small stress from a large one. A typical reaction to stress that we experience every day and several times starts with a cascade of about 1.400 chemical reactions! 2. Stress makes smart people do stupid things. Stress leads to, as neurologists would say, a "cortical block." Practically, stress stops certain functions in the brain, so we cannot react normally. 3. We can get used to stress. Some people have become so used to the daily rush, pressure and stress that it has become their normal state. Stress builds up easily, so sometimes we cannot recognize that we are actually under stress. 4. We can control our stress response. We don't have to be victims of our own feelings and thoughts. It is true that we can learn how to deal with stressful situations, so that it does not affect our mental and physical health. 5. The best stress control strategy is in the moment, because delaying stress relief will not have much effect. If we wait until the weekend to get drunk, do a workout or something else, our body has already suffered a stress reaction.
Stress also causes infertility
There are many consequences that long-term stress can leave on the body, and the latest research from the American School of Public Health "Mailman" shows that men who are under a lot of stress have a harder time becoming fathers, and may also have medical problems with infertility. According to this study, stress is the cause of lower sperm concentration, but also of their deformity and reduced mobility.
Infertility affects both men and women equally, and for members of the stronger sex, the quality of sperm is the key indicator of fertility, explain scientists who studied the spermograms of men aged 38 to 49 and investigated the connection between the results and the subjective and objective levels of stress they are exposed to.
Those who described themselves as being under a lot of stress, as a rule, had worse results of motility and sperm count. Although job-related stress did not have much of an impact on the findings, the scientists found that unemployed men were in a worse position when it came to fertility due to reduced levels of the male sex hormone, testosterone.
What else causes...
Stress leads to worry and anxiety, which can lead to hypertension. A strong heartbeat is one of the main signs of hypertension. If you can hear the heartbeat, then you need to see a doctor.
Headache
Have you ever heard of a "tension headache"? Too much stress can cause pounding and a sharp headache.
Nosebleed
If the pressure rises suddenly, without warning, the body's natural defense mechanism then releases some blood to control the pressure
Hair loss
In modern times, stress is one of the main reasons for hair loss. You will see premature balding in many people who are still in their twenties.
Memory loss
Stress can make you forgetful. Short-term memory loss often happens when you have a lot of work pressure or a stressful life. If your memory starts to fail, then you need to take a break and recover.
Excessive sweating
Excessive sweating, sweaty palms or feet, and feeling hot are signs of stress. If you are sweating profusely and you are sitting in an air-conditioned room, your stress level is high.
Premature appearance of gray hairs
Premature sitting happens due to genes or unbearable stress. Stress makes your hair gray at the temples. Today, even young people in their twenties have gray hair.
Persistent irritability
If you constantly feel like you need to yell at someone or release your energy in some other way, then you are definitely under stress. It's okay to get angry sometimes, but persistent irritability is more than just being angry.
Loss of immunity
Are you sick every month? If so, it is because stress affects immunity.
