Got overexcited having aired too much (15)

'got' is the definition.
The definition and answer can be both related to bodily activities as well as being past participle verbs.
Maybe there's a link between them I don't understand?

'overexcited having aired too much' is the wordplay.
I cannot really see how this works, but
'overexcited' could be 'hyper' (I've seen this before) and 'hyper' is found in the answer.
'aired' could be 'ventilated' (similar in meaning) and 'ventilated' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
