Hi!
Lovely to find your question...always great to see people interested in Ayurveda.
"Cooling foods" are Kapha-type foods...dairy, vegetables like cucumber, fruits like melons. Here is a great list of Water-Kapha foods, gemstones and colours...(read the section under "supressed Kapha" for things that are cooling...)

All the best with your "cooling off"! :-D
