Sick - scary 'feeling'

Anyone who is sensitive to ' pain ' is also easy to ' tickle '. Traditionally, they are ' bloody ' people. The tickling sensation is congenital because from 21 days of age, the child knows to tickle, manifests as wiggling when we touch the sensitive area.

Tickling only appears in certain areas of the body. According to scientist Charles Darwin, tickling reflects the evolutionary history of humanity. When gibbons turn into humans, chestnut skin becomes smooth. People are weaker. Many self-defense weapons are lost, so the senses must be more subtle to survive. At that time, insects (poisonous spiders, insects .) could burn, bite, sting so they were one of the most dangerous enemies.

Skin is forced to be alert, through certain sensitivity. It is sad and sad feeling, tickling whenever some creepy insect crawls up. That feeling is a signal to the brain, the brain sends a message to the body: the enemy begins to threaten or has penetrated, needing to respond immediately - immediately throw them away.

Recent research in the United States: Over 90% of respondents confess that they are " afraid of ticking " (the same rate as the number of people " afraid of pain "). However, each person's level of ' ticking fear ' is different, according to age, gender and personality.

To do the task of warning, on the skin there are receptors, tip of the nervous system to feel certain contact on the body. If itching occurs all over the body, anywhere, the ticking is selective. The skin is more exposed, thicker, more delicate like the back, lower legs, lower arms, face . less sensitive, less ticklish, less sad.

As for the positions that are not ' exposed ' like the armpits, the ribs, the abdomen, the area around the navel, the nostrils, the ears ., the ticking sensation will be very sensitive. Besides, they are also ' defensive lines ' deep, forcing the body to react in a timely manner, making the perceived level increase significantly.

Some people even divide the ' tick ladder ' by location. The most tickling place is the ear hole, the nostrils, then under the corners, the hips, the armpits, the neck, the ribs, the soles of the feet ., but probably also depends on people.

In other words, the tickle reaction is the physiological instinct of a healthy body, which helps the body stay alert and defend against harms from outside. A tiny little worm that gets into your ears and you don't tickle is too dangerous, right?

Reflexists think that tickling with pain is the same kind of feeling, the same mechanism, only different in degree. Those who are sensitive to pain are also easy to tickle. While itching has all kinds of causes, the cause of tickling is just . tickling (use your fingers to swipe hard into sensitive areas).

The tickling sensation is expressed by a loud laugh, laughing at the guest continuously, almost impossible to contain. What is the relationship between these two phenomena?

Physiologist defines: ' Laughing is a kind of reflex, caused by muscle spasms, rhythm, sounds and (in case of being tickled) involuntarily '. Laugh a nerve center on the brain that controls.

Information about ' ticking ' transmitted to the brain, light intensity is okay, but to a certain extent it causes a laugh as a response reflex. The Darwinist remarked: It is the chimpanzees - the apes that are closer to the people - when playing, wrestling, tickling at the armpits, also giggles. So it is tickling and laughing together like a picture with a shadow.

Unlike chimpanzees, when being tickled, the puppy knows how to tickle but doesn't know how to laugh. You try to tickle your stomach. Apparently he was tickled and reacted by bringing his back leg to scratch the ribs continuously. It was the movement that his ancestors had shown when he was bitten by bugs, lice, and bugs. This phenomenon shows that tickling is genetic.

No laughing

However, the brain has 2 different mechanisms for 2 types of tickle is tickling and tickling. This was explained by Darwin two centuries ago. He said: Cu just laughs when suddenly, not knowing the point will be stimulated. If there is preparation in advance, which means that the brain knows (even if it is the command of the hardworking, at any time), there is nothing unexpected. At that time, tickling was completely ineffective.

In books written that ancient times in China and Rome have torture forms that are hard to death.The criminal is tied on the board.Two feet were constantly watered with light salt water.A goat kept rotating the tongue and licking the soles of his soles.The person laughed and choked, laughing and writhing until he was exhausted.

Therefore, in 2 cases where you are tickled and tickled by others, even in the same position on the body, the same ' intensity ', meaning the nerve endings have the same feeling, It is identical from the location of the tick to the brain (this is confirmed when imaging resonance from this brain region) but the brain's ' treatment ' is still different.

In the first case, the brain ordered the center of the area to laugh out loud unrestrained voices. In the latter case, the brain does not move down to the area of ​​a ticked command. Can imagine it will " reassure " the messenger, the great idea: ' I know, pretend. Nothing! '

So, in a newspaper, when you meet a comedy that is too light, not enough to make you laugh, the critic is cruel: ' Watching that, there are some pictures while watching and' going to the ribs' then people just laugh '. He thought this was a clever satire, which turned out to denounce him without reality: Self-poking is still late to laugh!

To check the Darwinian hypothesis, Dr. Sarah-Jayne Blakemore did the experiment, using a robotic arm and she controlled it by pressing the remote to tickle her, she still " tickled " as usual. At this time, her brain was also tricked! Again, those who suffer from paranoid psychosis, always hallucinating, regardless of whether they are real or not, laugh and laugh when they tickle themselves.

Laughing is related to the fact that it can enhance communication. The mother who is tickling her child is to listen to her laughing for fun. A child who laughs (in a non-self-conscious way) is to respond to a gesture that shows his mother's affection and affection. Young people who love each other sometimes ' poke ' each other to show affection

What character do people fear?

Many people are so afraid of tickling that others do not need to touch me, only to scratch the 2 index fingers and get close enough.

Being afraid of ticking is nothing bad, whereas it proves that you have a sensitive nervous system. People with neurasthenia, depression . very little fear of tickling. Normally, when you are afraid of tickling, it means that you are in a comfortable mental state, and naturally you are not afraid to tickle, meaning your nerves are ' problematic '.

Psychologists affirmed, fearing tickling speaks of a human character. People who are easy to tickle are often more passionate lovers, more passionate, more active and in the life of a couple are also stronger than those who are less ticklish. It can be said, what is the person who is not tickled is often cold, emotionless and lazy in love.

Another psychological investigation also concluded that people who are easy to tickle and fear are often more interested in other, softer people (especially women) than those who are indifferent to tickling.

Tickling also relates to the mood. It was easier to tickle when I was sad. While watching a comedy show, filled with laughter around, only a little bit of humor made you laugh and laugh. On the other hand, speaking foolishly if you have to stand in front of a gun, even if the worm enters the ear canal, the mosquito will fly into the nostrils and people will not have a drop of ' sad blood '.

Tickling - tickling - laughing is the 3 continuous links. At that time, the brain released some excited chemicals like endorphin, enkaphalin, dopamine, noradrenalin, adrenalin . So, it also works to create sexual desire because it stimulates the sensory areas in the skin. . Probably more than anyone else, the young people immediately understood that it was a very light tickle, a tickle like a chicken feather.
