Some suggestions include:  Consider running through sprinklers.     Have a water fight with a sibling or friend(s). Having a water gun fight is effective and fun too. Dunk your head in cold water. Pour a bucket of iced water over your head (Instagram ALS ice bucket competition). Have a water balloon fight with your friends. To keep your kids cool, get a paddling pool for them and fill it with cool water. You could also put up an umbrella to keep them in the shade. Grab a companion, a hose, a sprinkler, a water bottle or water gun and flood your yard. Don't do this if you live under water restrictions. It keeps you cool and feels good.
