gaia spa at the Hyatt Regency Istanbul: not a replacement for your local hamam, but a fab treat if you're looking for a gentle, contemporary parallel to ancient bathouse culture
Put your feet in a bucket of water. Cooling your feet will help cool your body. When the water in the bucket becomes hot as it may after your feet have been heating it, put the bucket aside. Its temperature will drop in time. That same water can be used to wet a towel (as long as your feet don't stink - you're wiping your face with it!) or too keep your plants alive.
