Stress- advantages and disadvantages

Stress is bad but good

A unique piece of writing that reveals the negative and positive features of the psychological state that targets men and women

 

 If you leave home early in the morning, you will have an accident. Arrived at the office, then there was a problem with a colleague. Arriving home in the evening, he was greeted by his wife holding a gas and electricity bill in her hand. Just now the scale of patience is full, there was such a problem of mental stress that you sat holding your head.

 

Young and old and children, every human being is exposed to stress at some point in the day. This pressure then affects the thoughts and has the power to change the situation but it does not end there, mental stress also causes physical changes in us. The human body then releases various hormones that prepare us to attack or provoke us to flee. These chemicals then raise our blood pressure and heart rate, so we start breathing faster. In addition, it affects our memory and our ability to learn.

 

For example, a student went to a well-prepared exam. But he did not do well as expected. During the exam, he forgot important parts of the answers. He remembered her again hours later. One of the main causes of memory loss is stress caused by fear of exams. It temporarily disturbed the student's senses.

 

These effects of stress have been known to psychologists for a long time, but now research has revealed that this psychological and physical condition actually has both negative and positive aspects. Experiments have shown that stress enhances our memory in certain situations, although we do not necessarily remember the information that makes us successful. On the contrary, students who cannot memorize the lessons during the exams must remember that they went through a lot of stress, anxiety and "tension" at that time.

 

Psychologists have discovered that emotionally-charged moments, whether negative or positive, are unusually well-preserved in memory. For example, remember your significant experiences during the past year, most of which will be related to happiness, pain, stress, grief, etc.

 

For a long time, experts have been trying to find out what role emotions play in the formation and interpretation of memory. Now, research and experiments over the past few years have shown that the effects of stress depend on time and duration. It is possible to know the details of both of them that stress will increase or decrease memory. Experts have also revealed that stress becomes harmful after a certain period of time.

Our defense system

 

When we find ourselves in a critical or dangerous situation, our body's natural defense system is awakened. As a first sign, an organ in the depths of our brain, the hypothalamus, sounds an alarm. This alarm then triggers intermittent movements. The first activity releases specific hormones, then the second activity releases a set of different hormones.

 

Both of these activities are actually our defensive weapons. Not only do they help us cope with stress, but it also improves our memory so that if we encounter such a situation in the future, it can make things worse.

 

Activity 1: First, under the harem, the shark sends a signal to the adrenal medulla through the sympathetic nervous system. This location is in the center of the gland above the kidney. The spinal cord then releases two stress hormones, adrenaline and noradrenaline. These hormones cause the body to respond to "fight or escape".

 

These hormones then stimulate the body's energy reserves, increase blood pressure and increase heart rate so that the nerves get more nutrition, breathe faster so that more oxygen reaches the brain, a natural painkiller that relieves pain as a defense. Releases the relevant organs and also activates platelets so that there is minimal bleeding in case of injury.

 

Activity 2: After a while, our body secretes more hormones through the three internal organs, the pituitary gland, and the adrenal cortex. Corticotrophin-releasing hormone is first secreted from the inner harem to the pituitary gland through a special system of fine fibers. This almond-like organ is located in the lower part of the brain.

 

The second hormone, adreno corticotrophic hormone, is released in the pituitary gland due to corticosterone. This second hormone flows through the bloodstream to the spinal cord and releases a third hormone, cortisol. Cortisol is the most important stress hormone.

 

Strengthens cortisol, adrenaline, and noradrenaline as well as restores our body to normal. It strengthens the body's immune system and converts fats into glycogen to replenish energy reserves.

 

These separate activities explain why stress has a paradoxical effect on our memory. The first activity increases our perception and enhances our experience but the second activity stops the process of increasing our knowledge.

 

For example, you arrive at the test center late on exam day. It's easy to remember the stress you felt then. Because you went through that experience yourself. But the stress you endured while memorizing the answer during the exam is hard to remember. The reason is that many hours or days after the answer you memorized, you had to go through exam stress.

Experiments on mice

 

Experiments on animals, especially mice, also show how stress affects memory and learning. It should be noted that rats, chickens and other vertebrates also release hormones and neurotransmitters like us during stress. In the same way, animals, like humans, remember places and events. For example, "Where did I get food the day before?", "Where is my nest?", "Which places are dangerous and should not go there?", Etc. The reason is that stress-related events are necessary for survival.

 

There has been an interesting experiment in recent days to find out what effect stress hormones have on memory in animals. Experts filled a tray with water and left a rat in it. The rat did not know that there was a platform made of clear glass in the middle of the tub on which he could climb away from the water. In the beginning, each rat accidentally discovered the platform by clapping its hands and feet, but when the five rats went through this experiment several times, they noticed the special features of the platform. Then, as soon as they were released into the water, they would go straight to the platform.

 

Significantly, stress hormones play a key role in this learning process. In fact, when experts removed the glands of two mice (hormone-releasing), they had difficulty finding a platform. That is, they spent more time searching for the platform than the other three mice.

 

But experts have also discovered that humans and animals if constantly under stress, do more harm than good. Stress then blunts their mental and physical abilities and they find it difficult to carry out their daily activities.
