Sarein springs is heated by inactive volcano in mount Sabalan, Iran’s second highest mountain. Its water contains sulphur particles and it is believed that it is good for bone and joint pains.
1990’s earthquake caused some of the springs to get colder or hotter.
The word Sarein in Persian means “Spring’s Outlet”.

A 2010 study suggest using “open-space” springs
As a radioactive element with great solubility, radon is found in almost all the water sources, especially mineral springs. Having a volcanic origin and being mostly hot springs, the mineral water springs of Sarein are among the radioactive waters which are often used for sedating rheumatic, nervous and joint pains.
The measured radon concentration in 9 hot and cold springs of Sarein is lower than the standard limit. In addition, the accumulation rate of radon emitted from the springs is not posing a risk to human health, considering the fact that most of the pools are of open type.
Comparing the concentration of the accumulated radon in closed spaces of 25 selected locations around Sarein mineral springs with the standard limit indicates that radon is concentrated neart the hot springs and, if inhaled for a long time, might results in cancer and a short lifetime.
