Why are tickles ticklish?

Professor Hallux investigates!

Some people love them and others hate them but what makes tickles ticklish?

Because areas that are ticklish are often the vulnerable soft areas on our bodies, some scientists think tickling is a safe way for adults to teach their young to react to attack.

As you might know, it’s fairly common to cry out and even lash out when someone’s tickling you!

This explains why you can’t tickle yourself… Your body knows that you aren’t a threat to yourself and so it doesn’t need to react.

Although it can look like the ticklee is laughing, that response isn’t the same as laughing at a funny joke – it’s triggered by a process called the Rolandic operculum – it basically means that the person can’t help it!

Some people even believe it might be linked to fear!
