Consider the biology of fear.
This emotion is familiar to all people - even once all of us have found ourselves in a situation where we are afraid of something.
People interpret it as an unpleasant emotion, although some try to artificially cause it and resort to extreme entertainment for adrenaline.
Often fear is justified and an emotion caused by real factors, for example, it is impossible not to be afraid when you know that you are alone at home and suddenly you hear footsteps. However, sometimes this emotion is inappropriate - how many times have you been scared by a character in a horror movie? Even you knew that nothing real is happening on the screen and behind the mask of a monster is a charming actress.
Physiological changes occur in the body during fear.
The following symptoms are characteristic of fear:
- Accelerated heartbeat;
- Frequent breathing;
- Sweating;
- Cold hands;
- Feeling of nausea;
- Feeling of heart failure;
- Shortness of breath and chest pain;
- Piloerection (when, due to muscle contraction, the hairs "stand on end", that is, a kind of goosebumps develop).
Metabolically, the blood glucose level reaches its peak, the body prepares for a physical reaction and begins to store energy. At the same time, the level of calcium and leukocytes also increases.
The hippocampus and prefrontal cortex help the body to respond to and control fear. These areas help us to understand whether our fear is based on a real reason or not.
Psychologists consider a phobia as an anxiety disorder. Genetics and environment contribute to the formation of a phobia. Sometimes the cause of a phobia is a past life trauma.
