Mud bathing in Miami Beach, Florida

A mud bath is a bath of mud, commonly from areas where hot spring water can combine with volcanic ash. Mud baths have existed for thousands of years, and can be found now in high-end spas in many countries of the world.
Mud baths come from many sources:^[1]

• lakes (e.g. Lake Techirghiol)
• saltwater sea (e.g. Dead Sea in Jordan^[2] and Israel)
• hot springs (e.g. Calistoga, Napa Valley, California)
• mud volcano (e.g. Pulau Tiga, Malaysia,^[3] El Tutumo, Colombia^[4])

Mud baths in the United States are mostly found at the resorts in California and Miami Beach, Florida. The mud is a combination of local volcanic ash, imported Canadian peat and naturally heated mineral waters. Historically, the mud bath treatment has been used for centuries in Eastern and Western European spas as a way to relieve arthritis.
Also, in Romania, Lake Techirghiol is famous for treatments with mud baths. The lake's hypersaline environment was born due to the successive evaporation of sea water that remained in its basin after a tectono-errosive phase exhaustion created a fluvial-marine firth, and the lake's link to the sea was closed.. The accumulation of salts in the water is also a result of a semiarid climate with higher temperatures in summer, leading to pronounced evaporation. The lake's higher salinity (83.6 g/l in 1970, and 63.6 gl/l in 1980), in spite of a decrease over time, has been a bottleneck in the selection of the lake animal and plant species.^[5]
