- put ice cubes in your clothes. they will keep you cool for a little while, and when they melt they will continue to regulate body heat
- put ice cream in your food. it will not only keep you cool, but it will taste delicious. turn your ham sandwich into an ice cream and ham sandwich
- wear long clothes, expose as little skin as possible to prevent sunburns
- use liquid nitrogen to help cool yourself off
- consider cryogenic stasis
@mjdxp I have to admit, I sometimes do the first thing with the ice cubes when it's really hot @elilla
