Does Eating Snow Dehydrate You?

If you’re doing some backcountry camping or trekking during the winter, and you’re low on water, then you might be tempted to just eat some snow for hydration. After all, snow is really just frozen water, right?

Well, yes but that’s not exactly how it works with dehydration.

In fact, if you’re feeling dehydrated then eating snow is not a good option. Instead, you need to get yourself some liquid water. 

Sounds crazy, right? So, let’s dig into this a bit more.

Will Snow Really Dehydrate You?

Yes, eating snow dehydrates you. Trust me, I know this sounds insane since we all know that water freezes into ice and snow is just precipitation that has frozen.

But, when I explain the “why” here, it will all start to make sense to you.

While snow really is just frozen water, when you eat it that means that you’re consuming something that is solid instead of a fluid. Water itself is a fluid, of course, where ice is the solid form.

So, you’re chomping down on that snow and now your body has to take it and convert it into a liquid form. Perfect! This is exactly what you need.

Except…your body has to work at warming that snow to melt it into a liquid and warming your body temperate back up after eating something so freaking cold. And all that energy that the body exerts means that it just dehydrates you a bit more.

Eating the snow can also lead to hypothermia, which of course is not something that you want to deal with. 

So, what you end up doing when eating snow is creating more dehydration than you started with! What a slap in the face, eh?

How You Can Hydrate With Snow

So, since eating snow won’t rehydrate you, then you might be wondering if you can melt snow and use the melted snow for hydration. Answer: yes, you can hydrate with melted snow!

To hydrate with snow, you need to warm it up to melt it into water. Obviously, using your camp stove a camp fire is the easiest way to heat up some snow so that you can drink it for hydration.

If you don’t have access to a heat source, then you could put the snow in a cup, bottle, or bag and hold it close to you and use your body heat to melt it. Though you’ll have to be careful not to get hypothermia.

It’s important to remember that snow itself may now be considered clean for drinking. So, you’ll definitely want to avoid any dirty snow, of course.

And, of course, it’s ideal if you purify the melted snow water before drinking it. Melted and purified snow is an awesome source of hydration when your outdoors and feeling dehydrated with no access to water.
