How can vinegar take the heat out of a sunburn?

Answer:

I am not aware that it can. I would imagine pouring any cool liquid over a sunburn will chill it down some, but I am not aware of any properties that vinegar would possess that would improve the patient's comfort or condition.

I would instead consider a topical benzocaine cream, or something similar.
