Everyone has seen the appearance of anger before, the eyebrows are furrowed, the facial muscles are tense, and it is very ugly. Everyone in life gets angry when things don't go their way, and sometimes they get angry. Although anger is the outpouring of a person's normal emotions, if you are constantly angry, it can also bring physical and mental illness to yourself.

A knife can kill a person, and qi can kill a person. This is indeed good, Zhuge Liang is angry with Zhou Yu, and he just Zhou Yu to death.

There's a well-known experiment that was done at Stanford University. Place the nasal tube on the subject's nose and let him exhale, then place the nasal tube in the snow for another 10 minutes. If the ice and snow do not change color, it means that the subject is calm; If the ice and snow turn white, it means that the subject is guilty; If the snow turns purple, the subject is angry. Draw 1-2 ml of purple ice and snow and put it on the mouse, and the mouse will die after 1-2 minutes. After research on the composition of purple ice and snow, it has been shown that anger is prone to tumors.

According to the journal Circulation published by the American Heart Association, people who are irritable and irritable are more than twice as likely to have a heart attack or die suddenly than people who are calm and not easily angry.

A team of researchers led by Arne Wolf Sigman, a psychologist at the University of Maryland, did a study that included 44 people who had been diagnosed with heart disease and 99 people who had not. The study consisted of measuring the blood flow to each person's heart after exercise. The results of the study showed that people with dominance had a 47 percent increased risk of heart disease and irritable people had a 27 percent increased risk of heart disease compared to people who did not have a desire to dominate and had a peaceful temperament.

When you have a dispute with others, you must avoid a fierce quarrel, and try your best to avoid "shooting the case" and "getting angry", but learn to be able to take a "delaying strategy" when you are angry. If both sides are on fire, not only will they not be able to achieve a result, but they will also intensify the contradictions, and at this time it is necessary to adopt a "retreat strategy."

Take a look at the story below:

The caretaker, Lao Zhang, inspected the vegetable area and found that a middle-aged vendor had placed the vegetable basket on the passage outside the vegetable stall, which affected the movement of pedestrians, so he asked him to take the vegetable basket back. But the man ignored it. Seeing such a situation, Lao Zhang stepped forward and pushed the basket into the stall. But as soon as he turned around, the greengrocer pushed the basket out again. So there was a quarrel between the two sides. Witnesses said that Lao Zhang's face was very bad at that time, and he was obviously angry enough. After arguing for a few minutes, the vendor still did not obey the management, and Lao Zhang asked him to go to the market management office to solve the problem.

So, the two of them left the vegetable area one after the other. As soon as he walked out of a few dozen meters, Lao Zhang, who was walking behind, suddenly shook a few times and fell to the ground. The people next to him gathered around to take a look, only to see that he seemed to have had a stroke, was delirious, and the situation was very dangerous. When emergency personnel arrived, Lao Zhang had stopped breathing. The emergency personnel said that judging from the symptoms, Lao Zhang died of cardiovascular and cerebrovascular diseases, and the most taboo thing about such diseases is joy, sorrow and anger.

Don't die because you're angry, it's not worth it, it's ridiculous.

Dr. Harry Emerson tells an interesting story.

There is a large dead tree on a hillside on the banks of the Colorado River. According to biologists' estimates, the tree has been standing in that place for more than 400 years. It existed when Columbus landed in San Salvador. Over the years, it has been struck by lightning 14 times; It has survived countless avalanches and storms for more than four centuries. It stood majestically on the mountain, and had never been afraid of everything, but under the attack of a group of small, very inconspicuous insects, it fell! These insects pierced its bark and hollowed out its core, eventually disintegrating its fighting power with their weak but uninterrupted attacks. Just like that, a towering tree, a giant tree that thunder and lightning can't kill for hundreds of years, hurricanes can't blow down, and nothing can destroy it, but a group of pitiful insects that we can crush them into mud with just a light press of our fingers have conquered it.

Many times, we are like this weather-beaten old tree. We can also withstand all kinds of storms, avalanches, and thunderbolts in our lives, but let the angry "insects" unconsciously erode our body, mind and emotions, and eventually make us lose our strong bodies. Therefore, we must avoid getting angry.

Dr. Gannon, a professor at Harvard University in the United States, pointed out in his research report that when people are angry, the following changes occur in the body:

(1) The muscles and muscles at the entrance of the stomach are constricted, the digestive organs are spasmed, the blood circulation is accelerated, the pulse is accelerated, 180 to 220 times per minute, and even more than 220 times. This state will continue until the anger subsides, and then it will return to normal.

(2) The blood pressure rises sharply, from the normal 130 to 230; There are even more than two hundred and thirty. Some will have a cerebral hemorrhage and fall down.

(3) The coronary arteries of the heart are constricted, and sometimes stenosis occurs, and sometimes myocardial infarction occurs.

From this point of view, the impact of anger on the physiology is quite huge, and it is also extremely harmful mentally and psychologically.

Medical experts have also summarized eight points for the harm of anger to the body, which are:

(1) Causes skin spots to grow

A study of 5,000 women with pigmentation on their faces in the United States showed that when they were at a low emotional point, any medication for pigmentation was not satisfactory, and when some of these women had improved relationships, their pigmentation could heal on their own. "When a person is angry, there is a lot of blood rushing to the face, and there is less oxygen in the blood and more toxins. Toxins can irritate hair follicles, causing deep inflammation around hair follicles of varying degrees, resulting in skin problems such as pigmentation. The medical staff analyzed.

(2) Cause gastric ulcers

When angry, brain cells will work disorderly, causing sympathetic nerve excitation, and directly acting on the heart and blood vessels, reducing blood flow in the gastrointestinal tract, slowing down peristalsis, worsening appetite, and in severe cases, causing gastric ulcers. At the same time, it can also cause people to be unable to eat.

(3) Accelerate the aging of brain cells

Anger accelerates the aging of brain cells, weakens brain function, and a large amount of blood rushes to the brain, which increases the pressure on the cerebral blood vessels. At this time, the blood contains the most toxins and the least oxygen, which is no less than poison to brain cells, and the confusion of thinking when angry is a clear proof of the lack of oxygen in the brain.

(4) Hypoxia of myocardium

Each anger triggers a faster heartbeat, increased heart contractility, increased blood pressure, and thicker blood. A large amount of blood rushes to the brain and face, which will reduce the blood of the **** itself and cause hypoxia of the myocardium. The heart has to work twice as hard to get enough oxygen, and the heart beats more irregularly, which is more likely to be fatal.

(5) Liver damage

When angry, the body secretes a substance called "catecholamines", which acts on the central nervous system, causing blood sugar to rise, lipolysis to increase, and toxins in blood and liver cells to increase.

(6) Cause hyperthyroidism

Anger causes a disorder of the endocrine system, causing the thyroid gland to secrete too many hormones. The thyroid gland is an important organ involved in metabolism in the body, and when you feel your blood boiling, the thyroid gland is stimulated, which will cause hyperthyroidism over time.

(7) Injury to the lungs

When emotions are impulsive, the blood flow through the heart increases dramatically every minute, the demand for oxygen increases, and the workload of the lungs increases dramatically. At the same time, due to the hormone acting on the nervous system, shortness of breath and even hyperventilation occurs, the alveoli are constantly expanding, and there is no time to contract, so they cannot get the relaxation and rest they deserve, thus endangering the health of the lungs.

(8) Damage to the immune system

When angry, the brain orders the body to make a form of cortisol that is converted from cholesterol. Cortisol is a stress protein that, if accumulated too much in the body, can block the functioning of immune cells, make the body's resistance weaker, and even make the immune system dizzy to attack the body's normal cells.

If you want to have a healthy life, you have to be able not to get angry when things happen, and always keep yourself in a state of optimism.

As the saying goes, "Constant anger is the root of all diseases." The famous British writer Disraeli once said: "The life of a person who is angry about small things is short." There are two lines of poetry that we should always remember: "Longevity should stop the thunder and anger, and seek health must stop the thunderbolt fire." ”
