Why doesn't eating snow rehydrate?!
I've heard it's because it takes so much energy to change water from one state to another!.!.!.but I'm not sure I agree with that answer!.!.Www@FoodAQ@Com
Answers:
If you eat snow while it's frozen, it takes more moisture and energy from your body to melt the snow than you gain from eating it!.
You should melt it first, provided it's clean snow!.
You'd be surprised by how little water you end up with though!. Snow's composition is at a 10/1 ratio!. That means that one inch of rain will equal roughly ten inches of snow because ice crystals cover a larger area than a water droplet!.
You'd need around 80 square inches of snow to get one 8 ounce glass of water!.Www@FoodAQ@Com

Water does hydrate but under certain conditions it won't!. Both alcohol and caffeinated drinks have water but the alcohol and caffeine actually dehydrate!. So you have to drink more water to offset it!. A similar thing happens with ice except it has to do with body heat!.
Even a basic cold drink from the fridge will cause your body to go into heat up mode to warm the liquid to body temperature!. This can be good if your body does not need the liquid right away or if you are not in a hot environment because it does burn calories to do this!. The colder the liquic the more your body has to work to warm it up!. So it has to work hard with snow and ice!.
I don't know the exact calculations but I imagine it might be a little complex!. You would have to factor in the snow temperatuer and amount and how much energy your body has to use to warm it up to use!. However, it seems to make perfect sense that your body will work too hard to heat it up to actually be hydrated from snow!.Www@FoodAQ@Com

The first answer is pretty much what I was going to say!. It takes 8 cups of snow to make one cup of water so if you are dehydrated and need two cups of water to get back to where you want to be, you'd have to eat a whole gallon of snow!. I did a winter camping trip once and had to melt snow for water!. It takes A LOT of snow to get even a little water!.Www@FoodAQ@Com
Ever notice that 1 foot of snow when melted is like a half inch of rain !. !. !.You would have to eat a lot of snow as compared to a glass of water !. !. !. it may eventually rehydrate you, but you would be awfully tired of eating it !. !. !.just my opinion !. !. !.Www@FoodAQ@Com
