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!

3 Psychological experiments that went too far

Scientific knowledge and its tactics, as we conceive them today, has evolved throughout history, but in this long road, based on experimentation, not everything has been successful even leading to true tragedies as happened in the following psychological experiments. 3 Psychological experiments that went too far Little Albert The first of these rugged experiments is the one that took It was conducted in 1920 and was directed by Dr. John B.Watson of Johns Hopkins University, which sought to certify the Classic Conditioning by which the behavior of a subject through “learning by association”.That said it does not sound bad at all but to prove this theory, Dr.Watson used a baby of only 11 months, who like any baby did not have prejudices with animals, which scared again and again with strong metal strokes at the same time that showed an animal until totally traumatize the child, that after the experiment, he suffered a phobia towards anything that had hair.

There could be a planet like our Earth at 16 light years ...

Since 1992, when the first extrasolar planets, or exoplanets (planets outside the solar system) were detected, 1,288 planetary systems have been discovered, with some 2,030 celestial objects that could be considered as planets.Most of these objects are closer to Jupiter than to Earth, both in terms of size and composition, as they are usually gaseous, like the four great planets of our solar system. The search for planets outside our planetary system is oriented to an eventual identification of objects similar to Earth, both by location and size and composition, and we may be about to find one at a relatively close distance. There could be a planet like our Earth 16 light years away... A team of astronomers coordinated by Suman Satyal , of The University of Texas is studying a planetary system of the state Gliese 832 , a red dwarf with half the size of our sun, located 16 light years away and with two planets orbiting it: Gliese 832b , a giant Jupiter-like gas; and Gli...

There are many times that in Science Daily Online we have asked ourselves about the universe.This time we want to talk to you about the origin of it, about the Big Bang theory . The expression " Big Bang " means Big Bang.About 15 billion years ago there would have been a huge explosion that released enough matter to originate the Universe . According to this theory, everything that exists was ever concentrated on a smaller point in dimensions than an atom and, when the explosion , I release an impressive amount of energy .As of this initial explosion, the Universe began to cool and expand, until ten million more years later they would have cooled enough to consent to the formation of atoms that later joined, thus forming the first s galaxies.
