10 Not So Giggly Facts About Tickling And Giggling You Didn't Know!

> 10 Not So Giggly Facts About Tickling And Giggling You Didn't Know!

Some scientists believe, that tickling is an important social phenomenon, establishes a relationship between us and the people close to us, why not tickle yourself get. Others suggest, we are afraid of being tickled, as we think, that something skin crawling, and it becomes ridiculous only, when we see, it makes the other person, and have nothing to fear. 

Here are the 10 facts about this funny reflex.

1. So what exactly happens when you’re tickled?

In simplest terms, nerve endings in your skin send messages to your brain, eventually reaching the cerebellum, the area that regulates initiation of movement. “The cerebellum is activated upon unexpected touch,” says Samuel S. H. Wang, PhD, associate professor of molecular biology and neuroscience at Princeton University in Princeton, N.J., and co-author of Welcome to Your Brain. As a result of this sudden touch, your body produces a tickling sensation.

2. You can't tickle yourself

Why not? Essentially, you can’t surprise your own brain. “Somewhere in your brain, a prediction is made about the sensation your hand will produce, and that prediction suppresses the tickling response,” Dr. Wang explains.

3. Tickle spots are universal

Where should you launch your next tickle attack? Your best bet is on the sides of the torso (from the armpits to the waist) and soles of the feet. Research on college students reported in the American Scientist found that these were the most ticklish spots.

4. You can block a tickle advance

How? Just place your hand on the tickler’s hand. It’s a trick doctors know well. When doctors want to examine your belly, they’ll often ask you to place your hand on theirs,” Dr. Wang says. In doing so, you generate the same motion as the doctor, which tricks your brain into thinking that you’re the one doing the tickling.

The trouble is that catching the tickler’s hand during a surprise ambush can be tough.

5. You get tickled less as you age

Is tickling really just child’s play? People under age 40 are 10 times more likely to report having been tickled in the past week than people over age 40. One obvious explanation is that there’s simply decreased opportunity for tickling with age, as kids get older, for example. Hormonal changes may also decrease the tickle response as you age, which could make you like being tickled less.

6. Tickling can slim

It’s no joke: Tickling makes you laugh, which burns calories. A study in the International Journal of Obesity found that 10 to 15 minutes of laughing burns 10 to 40 extra calories a day — which could add up to one to four pounds in a year.

Granted, tickling doesn't burn as many calories as hitting the gym for 45 minutes, but “every calorie counts,” says Macej Buchowski, PhD, the lead study author and a research professor of medicine and pediatrics and director of the Energy Balance Laboratory at Vanderbilt University in Nashville, Tenn.

7. Men like being tickled more

According to surveys, tickling was slightly less pleasant to women than it was to men, and almost twice as many women as men ranked tickling as “very unpleasant.” This may be due to bad experiences related to non-consensual or non-reciprocal sexual touching, Provine says.

8. Tickling is your body's alarm system

Tickling may also have another important evolutionary function: Like itching, tickling may protect us by drawing attention to external stimuli, like predators or parasites. This type of tickle, called knismesis, rarely produces laughter and is a reaction that humans and animals share, says Christine R. Harris, PhD, associate professor of psychology at the University of California, San Diego. Think of a horse flipping its tail in response to a pesky fly.

9. Tickling can be torturous

If you hate being tickled, feel lucky that you weren’t around when tickling was used for corporal punishment. During the 16th century, a Protestant sect would tickle transgressors to death. Ancient Romans provided punishment through tickling too: They tied offenders down, soaked their feet in salt, and had goats lick it off.

10. That ticklish feeling can be fickle

Scientists don’t know why some people seem more ticklish than others. Provine says that the pleasure of the tickling experience is directly related to the relationship of the tickler and ticklee, which is why you might have more of a reaction in certain circumstances. A lover's ticklish touch might be pleasurable while an older brother's could feel like torture.
