Compression wraps are elastic bandages that wrap around a part of your body to keep swelling down. The wraps create pressure which pushes extra fluid out of a certain area. This improves blood flow to that part of the body and helps it heal faster. Compression wraps limit the veins' ability to expand and help blood move more efficiently, which assists the healing process. Further, reducing the inflammation near your wound makes it easier for your damaged skin to receive oxygen, which also speeds healing.
