Over the years, Olympic athletes have often displayed dark red circles on their skin, typically seen on their shoulders and backs. These marks, observed in numerous athletes, including Michael Phelps and Ruta Meilutyte, have sparked curiosity. The marks are not bruises but results of cupping therapy, an ancient Chinese practice used for over 2,000 years.

Cupping involves placing special cups on the skin to create suction, which draws blood to the area, enhancing circulation and aiding muscle recovery. Despite their appearance, the circles are harmless and serve as evidence of this therapeutic technique. Notable athletes like Phelps have popularized cupping, which is also used by celebrities such as Jennifer Aniston and Gwyneth Paltrow. While the red circles may look intense, they are a sign of cupping’s potential benefits in reducing muscle soreness and improving recovery.
