What makes people tickle

Evolutionary biologists and neuroscientists believe that we laugh when we are tickled because the part of the brain that tells us to laugh when we experience a light touch, the hypothalamus, is also the same part that tells us to expect a painful sensation. Laughing when tickled in our sensitive spots under the arms, near the throat and under our feet could be a defensive mechanism. Research suggests that we have evolved to send this signal out to show our submission to an aggressor, to dispel a tense situation and prevent us from getting hurt.

So why can't we tickle ourselves? So what is tickling? Why does it happen? Why is it impossible to tickle ourselves? And how do we tackle it? Something that's not very well-known is the fact that there are two kinds of tickling. The first kind, Knismesis, is caused by very light touch or movement across our skin. This doesn't make us laugh. Instead, this kind is more annoying. It also makes our skin feel itchy. That irritating itchy feeling that we get when a fly or an insect crawls on our skin is Knismesis.

The second kind is called gargalesis. This is the common kind, the one we love to give and get. This is when hard and heavy objects are put against the sensitive side of our skin. Repeated tickling can lead to trauma. One theory is that being ticklish evolved as a defense mechanism to protect vulnerable areas of the body and to show submission.

Another theory is that tickling encourages social bonding. Scientists found being tickled stimulates your hypothalamus, the area of the brain in charge of your emotional reactions, and your fight or flight and pain responses. In fact, the body movements of someone being tickled often mimic those of someone in severe pain. Older research shows both pain and touch nerve receptors are triggered during tickling. According to researchers , there are two types of tickling:. Gargalesis is tickling that causes laughter when someone touches ticklish areas of your body repeatedly.
