Why do you get nervous? Discover it and face it!

Nervous sensations are actually very useful.They go back thousands of years ago, at a time when most of what humans did not know, did not understand or could not predict, literally, that I could kill them .If the first humans were brave enough to walk on a meadow of unknown grass, for example, they could end up becoming the dinner of some wild animal that was on the prowl.So, get nervous in that situation , it was normal, and also necessary to be alert.

Why do you get nervous? Discover it and face it!

So humans and other animals developed a fear built into the unknown.In a dangerous, uncertain world, it was very useful for the first human beings to be able to react to danger quickly and effectively .This response to fear was connected to the nervous system.It was designed to give a great deal of strength, intelligence, and speed.When the first humans faced dangerous wild animals For example, the fear response helped them run and hide.It also helped them find strength, even to kill themselves, if necessary.

We rarely face wild animals in the modern times, but we still have the same fear response. When we are scared, nervous or stressed, our brain activates the sympathetic nervous system .This triggers the release of stress hormones, such as adrenaline and norepinephrine.And a cascade of reactions that include:

Increased energy and strength , heart rate and respiratory rate, which are accelerated in an effort to provide more blood oxygenated to the muscles.We pump the sugar through the bloodstream so that our brain and muscles can burn easily and quickly, which allows us to flee or defend ourselves from an attacker.This increase in energy and strength has, for example, allowed to some mothers, to lift cars under which their children had been trapped. Also more acute in sight and hearing , which allows us to see and hear better so that we can more easily detect dangerous predators.

On the other hand, during the fear response, the body sweats.This serves as a pre-cooled mechanism by which we are better able to function without passing heat.We also reject our perception of pain. It is for this reason that the victim of a bullet might not realize that he has been shot.Pain does not finally come into play-until that the injured person has detached himself from the fear response.When our response to fear comes on, our entire body is mobilized to do one thing and only one thing: sobrevivir.

Overcome it?

Many people think getting nervous about something is a negative response, and they want to eliminate it.But our fear response can actually become a force that we can take advantage of and use to our advantage.Although we don't normally have to fight or run in life situations or death, we can also turn fear into a force when we deliver a speech or have a conversation during a first date. Instead of being afraid of this answer, hug it and turn your biggest fear into its strongest point!
