​Fear is a natural, powerful, and primitive human emotion.

​ Fear alerts us to the presence of danger or the threat of harm, whether that danger is physical or psychological.

​Fear is a normal reaction to a threat while a phobia leads to a fear response even when you're not in danger.

​Acording to psychological research, it involves a universal biochemical response and a high individual emotional response.

​Fear is composed of two primary reactions to some type of perceived threat:

​Biochemical and Emotional.

​

Fear is a natural emotion and a survival mechanism. When we confront a perceived threat, our bodies respond in specific ways. Physical reactions to fear include sweating, increased heart rate, and high adrenaline levels that make us extremely alert.

​Biochemical Reaction

​This physical response is also known as the “fight or flight” response, with which your body prepares itself to either enter combat or run away. This biochemical reaction is likely an evolutionary development. It's an automatic response that is crucial to our survival.

​The emotional response to fear, on the other hand, is highly personalized. Because fear involves some of the same chemical reactions in our brains that positive emotions like happiness and excitement do, feeling fear under certain circumstances can be seen as fun, like when you watch scary movies.

​Emotional Response

​Some people are adrenaline seekers, thriving on extreme sports and other fear-inducing thrill situations. Others have a negative reaction to the feeling of fear, avoiding fear-inducing situations at all costs.
