Which measure can help stop bleeding, prevent swelling, reduce pain, and bring down high fevers?

Explanation:
Cold application works by causing blood vessels to constrict, which slows blood flow to the injured area. That helps stop bleeding and reduces swelling because less fluid leaks into surrounding tissues. The cooling also numbs nerve endings, which lowers pain, making the area feel more comfortable. When used on the skin, a cool surface can help bring down a fever by lowering body surface temperature. In practice, use a barrier between the skin and the cold source, apply for about 15 minutes at a time, and check the skin—remove if it becomes pale, numb, or uncomfortable.
