Saunas can be wet or dry. Wet saunas are often referred to as steam rooms and have a higher level or humidity, according to Sauna Talk. They provide heat through vapor, which is often created by throwing water on top of hot rocks. Dry Saunas use the same type of rocks but NO WATER is involved, so no vapor is produced. Sometimes electric or infrared rays are used to produce heat in dry saunas.
