Sports freak observers probably noticed on Saturday those small, circular marks on the backs and shoulders of all-world swimmer Michael Phelps.
Those circles are the end product of a healing technique called cupping.
Basically, cupping involves a cup attached to a pump. Athletes put the cup on their skin and create suction with the pump. Some say the technique increases blood flow and helps a person’s sore muscles heal.
According to WebMD, cupping therapy “dates back to ancient Egyptian, Chinese, and Middle Eastern cultures.”
The drawback of this therapy is the bruise marks which can take upto three weeks to go.
