History shows that:
Since ancient times human have bathe in cold waters for health benefits.
Even after they had developed water heating system, they still continued to bathe in cold water.
For example, the ancient Greeks, Russians, and Romans all used dips in cold waters for health and spiritual reasons.
Japanese practitioners of Shinto of both ancient and modern times would stay under ice cold water falls where they would mediate, this traditional practice is known as Misogi – you know, that one badass that just stands in the middle of the water fall as gallons and gallons of ice cold water drops on him, yeah that guy.
What is even more badass are the Ancient Spartans who would wake up early in the morning on splintered boards to two hours of intense calisthenic workout (bodyweight workout) followed by, you guessed it, a dip in freezing cold water.
