what temperature should you protect your hands from heat
Soak hands or feet in warm water â 99 to 108 F (37 to 42 C) â for 15 to 30 minutes. If a thermometer isn't available, test the water by placing an uninjured hand or elbow in it â it should feel very warm â not hot. Don't rewarm frostbitten skin with direct heat, such as a stove, heat lamp, fireplace or heating pad.
