Is it safe to eat snow?

Sa Pa, Mau Son, Pha Din . as well as many other places are snowing and many people may wonder if snow is safe? It turned out that according to many previous studies from countries that "have snow every year" , eating snow is an unsafe act even if it has not touched the ground.

Some ideas for the snow-eating argument argue that just getting the snow before it falls to the ground is edible because it is still clean. Or, if the snow is heavy, just remove the top layer, the deeper the snow the more clean and safe to eat. However, a recent study has shown that even if the snow has not touched the ground, it contains a lot of toxic things that people need to avoid.

Eating snow is not as safe as you think.

A study published in December last year in the journal Environmental Science by scientists at McGill University discovered that snowflakes contain not only a large amount of crystal water but also a lot of emissions in it.

More research was published in the Journal of Geophysical Letters by researchers at the University of Washington, who analyzed snow from many places across the United States and Canada. They found that the snow contained various concentrations of soot, dirt, . even some snow samples taken in areas far from the city, the industrial zone also contained these.

Therefore, it is clear that eating snow is not a beneficial action. Still not afraid of those substances and people still eat? Direct ingestion of snow can cause hypothermia, dehydration and cold burns in the lips. Therefore, researchers recommend that even in the case of survival, snow eating should not be done . In the survival guide of the US military has shown that in necessary situations, can only use snow after boiled up then let cool .

Obviously, the snow is very beautiful, very romantic, but maybe we should just watch and have fun instead of deliberately eating it as in our happy thinking because, that action is More harm than good for human health.
