A person should apply ice or heat when treating a venomous snakebite?

When treating a venomous snakebite, it is important to avoid using ice or heat directly on the wound. Ice can cause frostbite and further tissue damage, while heat may increase blood flow and spread the venom more quickly. Instead, the affected area should be kept still and at or below heart level, and medical help should be sought immediately. Always prioritize professional medical treatment over home remedies.
