Are cold packs applied directly to the skin?

Applying cold packs directly to the skin is not recommended because it can lead to localized frostbite or skin damage. The direct contact of the cold source with the skin can cause a drop in skin temperature too rapidly, which may not only be uncomfortable but also hazardous. To avoid these risks, it is generally advised to use a barrier, such as a cloth or towel, between the cold pack and the skin. A barrier helps to distribute the cold evenly and minimizes the chance of an adverse skin response while still providing the therapeutic benefit of reducing inflammation and numbing pain in the affected area. Thus, the statement that cold packs should not be applied directly to the skin aligns with safe first aid practices.
