The word stress is used on a daily basis, but what exactly happens in our body (also called “living body” in jargon)? It’s a bit technical. Stress refers to “a state of distortion that occurs in the body due to external stimuli”, but in the first place, our body is a system that adapts to changes in the environment and keeps the environment in the body constant. Is equipped. This system is called “homeostasis”.
For example, humans sweat when the temperature is high, and when they sweat, they become thirsty. Sweat is to reduce the body temperature that rises with changes in outside temperature, and thirst is to promote water supply to maintain an appropriate amount of water, both of which are due to the action of homeostasis.
Negative stress and positive stress
When you hear stress, you first imagine the negative things that come from worries and suffering. However, things that seem to be unrelated to stress, such as having fun and being happy, can actually trigger stress. Such stress is sometimes called “positive stress” in contrast to negative stress. Positive stress is stress that is acceptable to the body or beneficial to the body and mind. However, if the medicine is too much, it will be poisonous.

For example, one’s marriage or promotion, or a child’s advancement or independence is generally a happy and competing event, but on the other hand, changes in the environment and increased responsibilities have the potential to become stressors. If you try too hard there, you may suffer from physical and mental health problems.
Escape or fight- “fight or flight” reaction
Now, what kind of changes will be brought about in our mind and body by the occurrence of stress in the living body? As already mentioned, homeostasis works to keep the environment inside the body constant, as our body manages to adapt to changes in the environment.
However, that alone is not enough to respond to changes in the environment. For example, what do you do if you encounter a situation that makes you feel dangerous? You will have to escape from the situation at a glance, or fight and defeat any foreign enemies in the situation. If you continue to be extremely tense, your body will naturally get tired. In addition, it overuses the heart and blood vessels throughout the body, which can lead to cardiovascular disease.
Summary
Stress can be beneficial to us for a short period of time, or at moderate levels, but over a long period of time it can cause a variety of psychological, physical, and behavioral changes that ultimately occur. There is also a risk of developing stress-related illnesses. That’s why it’s important to think about how to deal with stress well. To that end, it is essential to know how much stress you usually feel and what signs you get if you get too stressed.
