When describing abstract situations such as fear and anxiety, these feelings are often present reflection in our body We will tell. In fact, these emotions that we feel through our perceptions make our hearts pound or our knees weaken.

Well, you can also experience these strong emotions in other parts of your body. why and how do we feel? Doesn’t it all actually happen in our brains?

Research shows that emotions are born in our brains, but our bodies carry out our brain’s orders.

From an evolutionary perspective, our brains protect us from a falling rock or a fast predator. It evolved to save.

In other words, we try to warn ourselves about possible dangers and so to keep alive to work.

But in modern life, our perception of danger does not require us to run away from a running predator. That is why we live in the new age The concerns are much more abstract and our brains view these worries as danger factors.

For example, thousands of years ago, exclusion from a tribe was a factor that would reduce our chances of survival, but today, exclusion from a social circle changes our lives. does not endanger it.

However, the brain is not aware of the difference between these two situations. don’t know the difference It may happen that it reflects the fear that our body experiences as a warning with the survival instinct.

In other words, when our brain perceives something as dangerous using different regions, it tries to warn us.

Because detecting threats is an essential part of the process of keeping us alive fast occurs.

For example, in ancient times, to survive when faced with a predator, you have very little time And you have to make good use of this time. There are different regions responsible for processing and communicating these responses.

For this reason, when the brain, whose main focus is to keep you alive, detects the threat factor, it transfers this information to the region responsible for understanding the emotional meaning of a situation and the response that should Be given. to the amygdala sends.

In this case, the amygdala is that of the brain bypassing areas related to logical thinking This message immediately activates physical responses.

To give another example: close to the amygdala sea ​​Horse It remembers what is safe and what is dangerous in the environment.

In this way make fear meaningful brings. In other words, this is the area that tells the brain not to fear the predator you see in a zoo.

In summary, the signals sent by the brain cause our body to respond in different ways.

When our brain decides that a fear response is justified in a certain situation, it immediately activates our body to prepare you for action. signals to action sends.

Sweating of our hands, sudden hot flashes, rapid heartbeat and similar situations occur exactly in this way.

In other words, when we find ourselves in a stressful situation, the brain enters the phase where attention increases and it is perceived as a threat, while the physical effects you will feel afterwards by signals sent by the brain takes place in the body. Because the brain reflects the stress or anxiety you experience. as a threat observes.
