Warmers operate on a chemical reaction with air similar to rusting. The warmer ingredients are iron, water, cellulose, vermiculite, activated carbon and salt. The heating process takes place in this fashion: The iron in the pouch, when exposed to oxygen, oxidizes and therefore produces heat (aka, Air Activated).
To keep warm, wear layers of clothing. This traps air between layers, forming a protective insulation. Also, wear a hat or head scarf. Heat can be lost through your head. And ears are especially prone to frostbite. Keep your hands and feet warm, too, as they tend to lose heat rapidly.
