Hi I am new here I have found an article from Internet: “Health Benefits of Belly Dancing”
Belly dance is a Western term for a traditional Culture of Arabs dance which is also known as raqs sharqi or sometimes raqs baladi (means "dance of country", and so "folk" dance). It is also sometimes called "Middle Eastern Dance", "Arabic Dance" or “Belly Dancing” in the United States.
For centuries, the role of Oriental dance in Middle Eastern society has been that of a folk dance that people would do at joyous occasions such as weddings, the birth of a child, community festivals, and other events that bring people together to party. It was a dance which men, women, and children did for fun, not a "performance" done to entertain an audience. Just as Americans at a modern-day wedding reception might do waltzes, two-steps, or even the chicken dance, so people in the Middle East would get up with their friends to shimmy to their favorite music.
