why do some people lose their ticklishness over time?

[damdu]

they just disappear

The primary cause seems to be 'natural neurodegeneration', which means that ppl's experience of the natural decrement of their neuro sensitivity throughout age.
Many ppl have become less & less sensitive to general sensations, including tickling sensation, throughout age.
It should be generally true, since older ppl are shown to be generally less ticklish than younger ppl based on scientific researches.
And the sensitivity (to tickling sensation) of some ppl may naturally degenerate to (almost) zero at certain ages.

The second but also important cause may be emotion/mood.
Some ppl may get increasingly negative emotion/mood toward being tickled, which can genuinely make them have less & less ticklish reactions over time.

The third reason may be that some ppl are good at getting used to tickling sensation throughout time.

Thread 'Ticklishness is more variable than constant for most people'

Nov 1, 2025

Though I don't have much experience of real tickling, I've concretely perceived that ticklishness is more variable than constant for most people.

A typical source of my perception is my observation on my peers in school & university.
Specifically, I observed most of those peers getting tickled mostly on their waists in my childhood & teenagerhood. Most of them did have obvious ticklish reactions in some (perhaps most of) time, but on the other hand, reacted obviously less ticklish or even virtually non-ticklish in some other time.

The second source concerns the 'self report' that I saw...

I believe so much of tickling is psychological. For me, it has increased overtime, but I think that is a direct result of engaging in therapy and putting in a lot of work around self acceptance and self love.

In doing so, I think I’ve been able to connect with my feelings, both physical and mental in a different way, and I’ve allowed myself to feel more vulnerable, which has led to feeling more ticklish in a session.

I think sometimes it might feel like it is going away because we don’t have the same physical opportunities, or because we are highly focused on stressors and anxieties, among other things.

Just my personal experience.
