All of the above

Explanation:

If someone has heat cramps, you want them to rehydrate themselves using a clear juice or a sports drink with electrolytes.

Gently massage and lightly stretching the muscles will reduce tension and the risk of tearing anything if the muscle is too tight.

Having your friend cool down in the shade is great because it will help them calm down and relax better.  

just be there for her.

explanation:

not necessarily literally but figuratively. also don't say things like "i understand how you feel", because even though you are trying to , you clearly don't understand how she feels (i'm gonna go out on a limb here and assume you've never had a heart attack). also just let her rest. that is one of the best things for you to do.
