There’s a way to stop the ‘tickle’ when someone’s fingers are accosting you.
How neuroscience can help you control your tickling response
Your brain predicts sensations based on your own movements and isn’t surprised when you try to tickle yourself. To combat the tickly feeling when someone else tickles you, cover their hand with yours.
Your brain can then make predictions about how it’s going to feel, and doesn’t produce the tickle response.
