For example, a traditional sauna is a wood-lined room where stones are placed and heated by wood, electricity, or gas. This heat is sent throughout the sauna. The temperature rises to around 180 degrees Fahrenheit. Traditional saunas also vary from Infrared due to the fact that humidity can be added by pouring water over the rocks.
Infrared saunas heat the body directly instead of heating the air around the person. These also do not get nearly as warm and heat to only 120 degrees Fahrenheit. Because of this, many people consider "infrared saunas" as "dry saunas".
Overall, most people prefer the infrared sauna to the traditional because of their lower price. Starting at just around $1,500 for saunas that can be taken home and simply plugged in.
