Why does our cheeks get hot and red too

[1/2"]

I was just curious why does our cheeks get hot and red too , when we get (suppose very) tight slap?
It's not a homework question and it's just a (stupid) observation .
Well I would be very happy if anybody answers.
(I don't know which subject this question is related to.Anyways)
Thanks in advance!

This is not physics, but physiology.

Your cheeks get flushed and hot because blood rushes to your cheeks, it's as simple as that.

Why does it "rush" to our cheeks?

Is this a homework problem? Think in terms of the blood's inertia.
