Ksitelävä
Ksitelävä is a Finnish term that translates to "ticklish" in English. It describes the physical sensation of being susceptible to tickling, often eliciting involuntary laughter or squirming. This sensitivity can vary greatly among individuals and even between different parts of the body. The exact neurological and psychological mechanisms behind ticklishness are still a subject of ongoing research, though it is generally understood to involve both light touch and pressure receptors in the skin sending signals to the brain.
The experience of being ticklish is often associated with social interaction and play, particularly between children
