September 2, 2026 · 11 min

Show notes

Most people know the feeling of ticklishness, whether it's the tickle attacks that bring about uncontrollable laughter or the feather-like touch from something brushing against your skin.

But why do we feel ticklish? Can we stop it? And why did we — and all our ape cousins — evolve this sensation?

Jonathan Webb speaks to Dr Anina Rich to explore the science of this everyday experience.
