But science and research suggest that snow can dehydrate your body and should only be your last resort for hydration. Now, if our organs want to digest something we consume, they will have to convert its temperature to body temperature.

Therefore, the body has to use quite a chunk of energy to convert snow into body temperature. This energy expenditure uses up a significant amount of water in your body. Thus, causing dehydration. Though it may sound counter-intuitive, eating snow is not the same as drinking water.

When you eat snow or ice, you are consuming water in a solid form. Your body will require e nergy to melt this ice into water. When you are sick or dehydrated, your system is already overloaded. Your body will need more fluids to convert ice into water, ultimately leading to dehydration.

In addition, the structure of snow is such that, as it falls, it tends to catch air pollutants and other toxins present in the environment. By the time snow reaches the ground, it becomes totally unsafe for consumption. In effect, eating snow may not be very good for your body and your hydration levels. In cold weather, you must look for hydration options other than snow or ice. So, what factors cause dehydration in your body after you have eaten snow or ice?

We explain the body metabolism that triggers further dehydration when you eat ice. When you eat snow, you are consuming water in frozen form. Your body must convert this solid into liquid, expending energy in the process. When you are already sick and dehydrated, this process puts an additional load on your body. In cold weather, your body is diverting all its fluid reserves to keep you warm. This process requires an additional fluid supply. Drinking the raw blood of any creature could result in the contraction of a pathogen like a virus, for example.

Sucking On a Stone: This old survival trick has been practiced all over the globe. The idea is to suck on a stone to cause saliva to flow in the mouth. You could even suck on the stone too hard and aspirate it inhale it , which could leave you choking.

Eating Snow: We all know not to eat the yellow snow, but what about the white stuff? If it is cold enough for snow to be present, then it is cold enough for hypothermia. Forget about brain freeze—this is core freeze! When people are told that eating snow might help dehydration, they also hear about the caloric theory regarding digestion. According to this, we burn more energy to heat the snow we eat rather than the power we get from the snow consumption. In other words — we spend more calories than we gain.

Instead, eating snow will make your body colder, and your system would be forced to invest calories to keep it at the same temperature level. Eating snow burns calories in two different ways — melting and digestion. The first topic which pops to my mind when we talk about eating snow and energy consumption is an e-book written by Dr. In fact, Dr. Weiner had found that eating a liter of ice would burn approximately calories. Does it mean that consuming snow will dehydrate you?

Well no, although in terms of camping it does make a difference. In fact, most of the idea of eating snow cross our minds is when we are spending some time in outdoor activities — otherwise, why would we even consider doing that? Still, the question of whether or not eating snow would actually hydrate you remains. Have you ever put a glass bottle inside a refrigerator? If you have, you probably know that once the water freeze they may pop up the glass into pieces.

In opposed to the general belief, frozen water occupies a higher volume and floats on liquids since its molecules feature a different form. It is not that ice contains more air — it is merely its inner bonds which play the role here. From that course of thoughts, we come to realize that eating snow would hydrate you just as much as drinking liquid water, even though it may feel less.

So you are outdoors camping with your friends and family and found yourself wondering whether or not you should eat a little snow to maintain hydration. For some of you it might sound funny; however, when you have a limited amount of water, this question becomes more and more relevant. Well, from my experience, eating snow does feature a few risks, and it is essential to consider those before putting it in your mouth.
