I'm snow cold & lonely....

[Timelord]

Beware eating snow in a survival situation. It can use a lot of energy in your body to convert it to water. this can do 2 things - 1) Cool you down even more towards hypothermia. 2) Use up energy resources.

Obviously aquiring the water is more important than solid foods in the more immediate term but if the practice is continued than it can contribute to points 1 & 2.
