May one bathe one's entire body in natural hot springs (e.g. Tiberias) or cold water on Shabbat?

ShabbatBathing

Synopsis

Bathing in natural hot springs (like Tiberias) is permitted even for the entire body, and certainly in cold water. However, hot spring water in a vessel is forbidden lest it be confused with fire-heated water. In practice, the custom developed to not bathe even in cold water in rivers on Shabbat.
