Why do some touches tickle?
A light touch makes Puschel giggle. Flauschi asks when tickling feels pleasant.

The short answer
The skin sends touch signals to the brain. Some light touches feel ticklish. How they feel also depends on the situation. Laughing does not automatically mean: please continue.

An imagined Wusel scene
Puschel and Flauschi investigate
Flauschi laughs when a soft feather brushes her arm. A moment later she says, “Stop.” Puschel puts the feather away straight away. They sit together and think: Flauschi laughed and still wanted it to stop. Both can be true.

Understand step by step
How it works – simply explained
Skin reports touch
Small nerve endings respond to contact and send signals onwards. Different touches do not all feel alike.
The situation matters too
The brain processes both touch and situation. Light contact may feel ticklish, unpleasant or barely noticeable. People differ.
No counts even during laughter
Laughter is not reliable permission. Anyone who dislikes tickling may say or show this. The other person stops; feelings need no proof.
