Now, I am wondering. Why some people are ticklish and some people are not?

Here is the answer that you seek. Why some people are ticklish and some people are not? Some people do indeed have an extreme tickle response known as Hypergargalesthesia. This condition is characterized by an intense sensitivity to tickling, leading to an overwhelming reaction to touch. Hypergargalesthesia is not yet fully understood by scientists. Factors that affect your degree of ticklishness. Skin sensitivity: Some people have more sensitive skin than others, which makes them more ticklish. Mood: Dr. Vyas says that anxiety can make you more ticklish, while emotions like anger may make you less receptive and responsive to tickling. We all process sensory information in different ways,” says Lear. “If someone isn't ticklish or actively dislikes tickling even when calm, that doesn't mean something is wrong with them—it's just a personal preference.

Some people are physically more sensitive than others, or as Dong puts it: “Everyone has different nerve density.” He adds that genetics could also play a part in ticklishness. Dong does, however, believe you can train yourself to be less ticklish. The relationship between being tickled and self-esteem shows a double aspect in men: It is positive in women who like being tickled and negative in women who do not like being tickled. While the palm is far more sensitive to touch, most people find that the soles of their feet are the most ticklish. Other commonly ticklish areas include the belly, sides of the torso, underarms, ribs, midriff, neck, back of the knee, thighs, buttocks, nose, feet, and perineum.

The somatosensory cortex is responsible for analyzing touch; for example, the pressure associated with it. The signal sent from the skin's sensory receptors also passes through the anterior cingulated cortex, which governs pleasant feelings [source: Blakemore]. Together, these two create the tickle sensation. Laughter when not prompted by tickling has all kinds of health benefits: it boosts immune system function, lowers our stress hormones, and even burns calories. Physical grooming involves desensitization to touch. Starting with innocent pats on the back or arm, an acceptable form of touching a younger person, the offender progresses the touch to hugging, tickling, and wrestling. Over time, this conditions the child/youth to increase levels of physical contact. Some people believe that they can desensitize themselves to tickling through repetition. However, scientific research has not uncovered a specific strategy that will help people become less ticklish.

Tickling is a form of flirtation and it can work and sometimes backfire. some people do not react well to being tickled. The soles of the feet and the underarms are two of the most common ticklish places on the body. One reason feet are ticklish is that they have more densely packed nerve receptors than most other places on the body. Upwards of 8,000 nerve endings can be found in your foot. This huge amount of nerves makes your feet more sensitive than other body parts, and more ticklish, too. People may hate being tickled due to the loss of control over their bodies, experts say.
