AccuWeather's Anna Azallion explains what scientists say are the risks that come with eating snow, whether it's off the ground or falling on your tongue.

Eating snow can pose health risks due to potential contaminants such as dust, chemicals, and microbes that snow collects as it falls and after it lands. Experts advise against consuming old, discolored, or dirty snow, and warn that even clean snow can lower body temperature and worsen dehydration if eaten in large amounts.

In survival situations, experts recommend melting and purifying snow before consumption to reduce health risks. Children and individuals with weaker immune systems should be particularly cautious, and snow should not be considered a safe snack.

Is it safe to eat snow?

is it safe to eat snow? Short answer, sometimes, but there's real risks. Snow starts out as frozen water forming high up in clouds, but as it falls and especially once it hits the ground, it can pick up all kinds of contaminants. Think dust, car exhaust chemicals and even microbes from animal droppings. That's why you should never eat snow that's old, discolored near roads or visibly dirty and eating a lot of snow, even if it's clean, isn't harmless either. Your body has to burn energy just to melt and warm it, which can actually lower your body temperature and make dehydration worse. So if you're ever in a survival situation, experts say melting and purifying snow, filtering or boiling it is much safer than eating it straight. The bottom line, a tiny taste of clean, fresh snow is usually low risk, but kids and anyone with a weaker immune system should be especially careful. Enjoy the snow day. Just don't make it your snack.
