    Water in streams, lakes, rivers, and springs is pretty much always a lot cooler than the air. Unless it’s a very small pond or a puddle, water is pretty cool, especially if you go deeper than just the surface to take your water.

    Icy water yes. But cold water was available, the whole reason people find cold water refreshing is because running water/spring water etc are cold and more likely to be safe to drink. While stagnant water were more likely to be warm and have more bacteria, making it lot less safe.

    You might only have ice-cold water during the spring if you’re near a river that just flowed down from the mountains but even most well water is going to be much cooler than surface temperatures.

    Cold water is easy to heat if you know how to make fire. Most early humans probably knew how to make fire. Hot water, however, is difficult to cool without refrigeration.

    Spring and well water is often cool. I don’t know about the water that comes down from the mountains. Does it retain it’s coolness when the snow melts and runs down into the valley?
