The Therapy Called Cupping
The unusual round dark red marks are caused by a therapy called cupping. This therapy leaves circular marks that can be mistaken for bruises.
The practice, rooted in ancient Chinese medicine, has been employed for at least 2000 years to treat pain, muscle stiffness, and respiratory issues.

This therapy involves creating suction in special cups using heat or air, which are then placed on the body. The vacuum pulls the skin and blood vessels towards the cup, often leaving marks on the skin.
This process is believed to draw blood to the area, enhancing circulation, and relaxing muscles and joints. There are also suggestions that cupping has anti-inflammatory effects.

Cupping’s anti-inflammatory effects occur when the enhanced targeted circulation, promotes the removal of potentially inflammatory elements and encourages fresh blood flow.
The cups can remain in place or are occasionally moved around for those more adventurous for about 10 minutes. After removal, they leave behind the distinctive welts.

High-level athletes worldwide endorse cupping, the technique they credit for their performance. In the US, it is sometimes used alongside acupuncture or massage. While a specialist typically applies the cups, some athletes are doing it themselves.
Phelps has unintentionally become a spokesperson for the practice. Members of the gold-winning US women’s gymnastics team are also among its supporters. Additionally, many in the NBA are enthusiastic advocates or cautious newcomers to cupping.
Swimmers and gymnasts who use cupping therapy claim it helps alleviate soreness in their overworked bodies. Former basketball player Kyle Singler said, “The bruises do look more intense than what they actually feel like. But the benefit from it is really great.”

According to Singler, cupping is used primarily for maintenance and recovery. It is an alternative medicine practice. While it doesn’t provide an immediate response, over time, it proves beneficial for recovery and loosening tissue.

Cups used in cupping therapy can be crafted from bamboo, glass, or earthenware. The precise mechanism of cupping remains unclear.
However, some researchers propose that placing the cups on specific acupoints on the skin causes increased blood flow or hemostasis, which in turn has a therapeutic effect.

Studies have also cited the use of cupping in health issues such as managing cancer pain, low back pain, and acute trigeminal neuralgia. The therapy has also appeared to be effective on acne and facial paralysis.

Therefore, dark red circles on Olympic athletes and other celebrities are not bruises or body décor but evidence of cupping therapy. This practice helps in body recovery and maintenance and offers therapeutic benefits
