Hydration???

okay here is the question.

say you are dying of thirst. my question is if you have a glass of cold water and a glass of warm/hot water. Would the cold one hydrate you more, or is it the same?

    i think cold water would hydrate you more

    probably due to this

    as temperature of water decreases its volume decreases until it reaches 4 degrees centigrade where it increases

    so one glad of cold ater has its molecules closer therefore hydration is higher in the cold rather than warm

    The actual water does the same, because water is water. However, if you could only drink one, you should drink the cold one. This is because (not only is it refreshing), but it will lower your core body temperature, which will make you sweat less (because sweat is trying to regulate your overheated body), which means in the future, you will lose less water due to sweat. This, in turn, will mean you will be more hydrated. If you are in a situation where you are no longer hot or sweating, then either water will do the same thing.

    ^^ This was assuming you were dying of dehydration due to sweat and heat. If you're dying and you're cold, you'd want the warm water to raise your core body temperature.

    Use the warm water. If you are dying, you don't have a whole lot of energy left. Your body has to use energy to warm up the cold water. And in either case, you would probably be in the hospital with an IV (at room temp) in your arm to rehydrate you.

    Warm water would be absorbed quicker....best if you're near dying!
