The song ‘Baby Shark’ is constantly stuck in my head and it’s driving me crazy. How can I get rid of it?

Like a broken record stuck on repeat, earworms can get stuck in our heads and drive us barmy. Don’t worry, BBC Science Focus is here to help press the stop button.

You could try chewing some gum – a few years ago, psychologists showed that this reduced volunteers’ susceptibility to earworms, the theory being that chewing somehow hijacks the brain processes that are involved in ‘subvocalisations’ (singing or speaking in your head).

Beware, though: if the task you take on is too easy or tricky, your mind will wander again, and the song will likely resume.
