Why does 「頭にきた」signify being mad at something?


Is there any source or explanation for the phrase「頭にきた」and why it means to be
angry?

For example:

> 彼の言ったこととその言い方にはイライラして頭にきた。

Why does "what he said and the way he said it came to my head" mean that I
should be annoyed or irritated? Why is 「頭」important and not something else? At
first glance, I thought that the phrase was similar to "気づく", but it is not.




I think of it as blood rushing to my head when I am angry.
