ELI5: Why do I stick my tongue out when I'm concentrating really hard?

I've done this since I was really little and have never been able to stop. I know its not just me as I see it on TV and other people all the time. What is the reasoning behind this? Why would sticking out my tongue help me focus?

Your tongue uses up a lot of brain power, specifically from your motor cortex, which is used for planning, sensing and executing physical movements. Sticking out your tongue stops it from moving so your brain doesn’t need to think about it and you can devote more concentration towards whatever it is you're doing. The motor cortex also plays a role in language and planning, so sticking out your tongue may help, even if it isn't a physical action that you're focused on.
