No, the title is not an allusion to the Teenage Mutant Ninja Turtles. When we say “staying cool” we mean it literally. It’s summertime, and that means it gets hot inside as well as out. Everyone’s first reaction is to reach for the air conditioner, but the truth is that there are easier, cheaper, cooler, and most importantly, greener routes to take towards staying cool in the summertime.

The Daily Green provides a number of options to stay cool during the summer that are greener than energy-gorging air conditioners. One suggestion, in particular, got us pretty psyched. Take two ice cubes and place one on each of your wrists, then tie them down with towels or rags. By doing so, you can lower your body temperature by as much as three degrees for an hour!
