There’s a connection between being wet and getting cold, and vice versa for heat, says engineer Lia Lavoie.

To ensure your body temperature doesn’t fall too quickly in cold environments, invest in clothes made of wool instead of cotton — they’ll absorb more moisture so that dampness doesn’t linger on your skin. And, of course, do your best to stay dry.

Don’t eat snow for hydration unless you absolutely have to

Lavoie also points out that your body uses a great deal of energy to convert matter from one state to another.

That’s why he says you should only eat snow as a substitute for water as a last resort. In gaining that small amount of hydration, you’ll give up precious body heat.
