Why is cold water or ice water more refreshing than lukewarm water or hot water? Why do humans prefer cold water to hot water even though hot water still hydrates us?

I like pouring myself a cup of hot water and putting a couple ice cubes in it.

The sensation of simultaneously drinking hot and cold water at once is surprisingly stimulating.

I think we prefer to drink fresh water. Water that sits in the sun is hot and stagnant. (Danger! Germs!) We’ve learned that’s not good.

Drinking water is a good way to cool down. I think that can as to a refreshing sensation when you are overheated.

When it comes to beverages – not just water – temperature affects texture and taste. Coca cola fresh out of the fridge has a unique texture, very smooth.

One of the reasons is the taste. Water tastes different based on its temperature. Hot water is the least enjoyable wheras cold water for most, tastes the best. Though some prefer room temperature.

But typically when you are thirsty, your body is dehydrated. This can increase your body temperature.

Cold water helps cool your body temperature, hydrates you and as mentioned, often has the best flavor of the three.

Just like a cold soda has a much better taste than a can sitting in the sun or at room temperature.

* Think back to before we had a modern infrastructure that can bring water right to our home.
* We got water from somewhere outside.
* Water that sits around and gets warm in the sun is also loaded with bacteria that can kill us.
* Water that is moving doesn’t get the change and most water that is moving comes from an underground source and is relatively cool.
* So over the years humans that liked warm water died from it and humans that liked cold water lived long enough to have kids.
* Now we all like cold water.
