How does the brain react on when we are scared ? how do some fears appear? what are the ways to fight our fears?

Fear is a very strong feeling that makes us feel uncomfortable. Our brain impels our body to react to fear in many ways. Some of us can`t act at all staying in the place where they were spooked due to the fact our brain sends a kind of signals paralyzing our nervous system. Others, however, start trembling and looking around as if they are looking for help, they squeeze their fists as though they would assault somebody or something. And that is true for people of the sort because their brain injects certain hormones into the blood impelling such people to act to protect themselves from a danger.
        Most of the fears we are exposed to are ingrained in our brains from childhood. We have been scared to death with possible traumas, insecurities and troubles that our parents, friends and close relatives described so brightly. Newspapers and TV have added some terrific stories that can happen to us if we are not careful enough.
       I am sure that the best way to cope any fear one encounters with, - is to do what he or she intends to. There is no other way out of the situation. Only if we try doing what we are planning we will get a chance to shatter any kind of a fear. And be sure, our brain will undoubtedly remember a positive result we achieved. And if a similar situation arises in the future we will not be frightened again, because our brain will analyse the situation and prompt us the best way to deal with it rather than sprinkling adrenaline into our blood.
