What is the effect of applying warm lotion to a resident's skin?

Applying warm lotion to a resident's skin is effective primarily because it moisturizes the skin. Warm lotion can enhance the absorption of the moisturizing ingredients, which helps to hydrate the skin more effectively than cooler products. The warmth can also increase blood flow to the area, which may aid in the overall health of the skin by promoting better circulation and nutrient delivery.

While there are other potential benefits like temporarily increasing skin temperature which could promote sweating or help relieve pain indirectly due to the warmth, the primary intention when using warm lotion is to provide moisture and nourishment to the skin, making it softer and more pliable.
