Can You Get Sick From Eating Snow
It is generally safe to eat snow if it does not contain toxic substances. Most people use snow for drinking purposes or for making ice creams but there are some exceptions. If the snow is Lilly white, you can safely ingest it. Some people have gotten sick with fever, nausea, diarrhea, and vomiting while ingesting snow.
The main reason that eating snow is considered to be a bad choice is because of pollution caused to our bodies by eating it. While there is a chance the snow that you are eating has traces of pollutants in the atmosphere, the same is true for the air that we breath, and studies show snow is still safe to eat in moderation. Doctors and researchers believe eating snow is safe for most people, provided that it is clean, white snow collected from a location with no pollution, in an undisturbed area, and not from windy plains, but there is always the tiny risk to consider for those with compromised immune systems or young children. Scientists also concluded that the amount of contaminants that could potentially be present in the snow is actually not large enough to do any harm.
The danger comes mostly from toxic substances, like ice melt or antifreeze, that could be infecting the snow. Because of air pollution, substances other than water can seep into snow even before it hits the ground. As the snow falls, it may pick up small, but detectable, amounts of chemical pollutants from the air. As it falls across the sky, the snow, with its intricate gridwork, forms a kind of net to capture pollutants that might be present in the atmosphere.

If you think about the way that snow forms in the atmosphere, it is basically frozen distilled water crystallized around tiny particles, which is why it is probably more pure than what comes out of your tap. Because it is primarily water, snow is naturally watery, but there is also the risk it could become polluted by an array of chemicals, or even air pollutants, particularly if it falls in an urban area.

That means that if you live in an urban area, where you have lots of transportation, chances are your snow is loaded with pollutants. Even if you are not living next to a contaminated area, snow falling on you may have picked up pollutants from other areas.
A 2015 study by McGill University in Canada found that snow in urban areas could become toxic due to air pollutants caused by vehicle exhaust. Dr. Parisa Arry, professor at McGill University in Canada, told The Huffington Post that snow in cities can soak up toxic, cancer-causing pollutants, and the snow itself, when combined with these pollutants, could result in the release of even more dangerous compounds.

Just like other forms of rainfall have contaminants — such as pollutants that dissolve into the rain — snow also has other chemicals and particles. Particles are collected when the snow falls on the ground, and can be higher if it is been a particularly windy day.
Because snow acts like some kind of air filter as it travels down to the ground, the first minutes of the snowfall will be the messiest. In fact, since snow soaks up pollutants as it travels, the first hour or two of a snowfall acts like a scrub brush for the air. After several hours, falling snow has pulled much of the pollutants from the atmosphere, so you get a much safer crop than you would have had if you went outside to pick up snow immediately.
Be sure to use the freshest snow that you can find, because wind deposits a fine layer of soil and pollutants on the top layer of snow for up to a day. It is suggested that if you are truly looking to eat snow under any conditions, wait for several hours after it has fallen, so there might be less contaminants. If you want to eat the cleanest snow, wait for a couple hours after it has fallen, then pop your tongue in (via NPR).
The best way to avoid eating contaminated snow is by picking up the fresh snow that has fallen a few hours after you have snowed. In the event of falling snow, some people, such as backpackers, are better off eating snow that they picked up straight out of the sky.
If you are going to eat snow, one of the more common recommendations is to only consume limited amounts, like one to two handfuls a day. It is also a good idea to know that if you simply wait for a couple hours, then binge-eat snow that has collected midway through a storm, then you have got the best odds of eating nothing but pure, frozen, celestial water. There is some good news to be found. In general, eating tiny amounts of snow does not hurt you at all, since it is small enough to clean up.
A tiny amount is usually considered safe and non-toxic, but eating large amounts may make your stomach hurt or give you side effects such as vomiting, diarrhea, or infection, if you are eating snow containing contaminants. Unfortunately, these chemicals may make you sick too if you eat them, so you certainly do not want to eat any snow that has been shoveled or plowed.
Contaminated snow can also make its way to your mouth and nose if you brush against it, and then hold your hands to your mouth. Snow also turns yellow when it comes in contact with pigments in falling leaves, pollen, dust, sand, and air pollution. Snow is just water vapor frozen into place, which means that a new, powdery snowpack will cause little or no health damage to your dog.
For the most part, dogs are going to be completely safe eating a bit of snow when out playing in the backyard. In short, dogs like to eat snow for a variety of reasons, like their natural instincts, the immersive nature of snow, and perhaps also because they are dehydrated and do not get enough fresh water. While snow is more like the dish and less the component in my favorite winter treat, Sugar in Snow, I still end up eating a little bit in the process.
You would not think twice about getting a snowflake on your tongue, but using snow to make snow-based ice cream, or melting snow to drink, can leave you wondering whether or not it is safe. If you are looking to consume a lot of snow, like if you are camping, you could melt the snow for drinking water, and then make sure there is added cleanliness by running it through any filters available (or using it to make distilled water). If the term contaminantsstill makes you a bit nervous, you can always choose to use shaving ice rather than the snow outdoors. Substitute shaved ice for the snow if you cannot seem to get past the contaminants word–or if only a light dusting has fallen in your area, and you still want a snowy treat on a winters day.
Is it safe to eat or drink snow?
Snow is used without incident by campers and mountaineers all over the world as their primary water supply. You can eat clean snow even if you live in a metropolis. Snow does travel through the atmosphere before it lands on the ground, allowing it to pick up dust and other airborne contaminants.
Why shouldn’t you eat the first snow?
Snow that has just fallen may seem pure, however, the initial flakes are not what you want to eat. This is due to the fact that they clean up contaminants in the ground and the air. After a couple of hours of snowfall, collect snow for eating. Refrain from eating snow on days with high winds.
Why can’t you drink melted snow?
However, it is typically not advisable to use snow (or ice) as a source of hydration. In addition to the risk of infection, eating snow might cause hypothermia and dehydration since it takes too much energy for your body to heat and thaw the snow after you consume it.
