What should you apply to a closed wound as part of proper care?

Applying a cold pack to a closed wound is an essential step in proper care. Cold therapy helps to reduce swelling and inflammation by constricting blood vessels, which decreases blood flow to the affected area. This cooling effect can also numb the sensation in the area, providing pain relief. Cold packs are particularly effective when applied shortly after the injury occurs, ideally within the first 24 to 48 hours, to minimize bruising and swelling.

Heat packs, on the other hand, are typically used for muscle relaxation and to alleviate stiffness in chronic injuries, and may worsen swelling in an acute injury situation. A wet cloth is not effective for managing closed wounds and can introduce moisture that may lead to skin irritation or infection. An alcohol solution is unsuitable for wound care as it can damage tissue and delay healing. Therefore, using a cold pack is the best practice for managing a closed wound effectively.
