You do actually! It's called yawning

Do you... do you yawn when you think too hard?

One of the reasons we yawn is because our brain is warm, not the thinking too much part lol

A quick Google does not name this as one of the several reasons for yawning. Any sources on this?

By lowering brain temperature and maintaining thermal homeostasis, the thermoregulatory theory suggests that instead of prompting sleep, yawning actually serves to maintain focus and attention, thereby antagonizing sleep.

So not concrete but it is one of the prevailing theories for one of the reasons we yawn

there are quite a lot of articles about yawning cooling the brain. in this princeton research they observed how much people yawn outdoors in the winter vs summer, and it was more common in winter. personally i don't quite believe this, because aren't we more tired in the winter anyway? https://www.princeton.edu/news/2011/09/19/more-sign-sleepiness-yawning-may-cool-brain
