Not only does dancing give you a brain-boosting increase in oxygen and make us feel happier, but it can also make us smarter. The mental activity required to move every part of the body with timing and rhythm can be more of a workout for the mind than reading or doing crosswords. The level at which dancing improves brain function does depend on the type of dance being performed. Something which requires learning a lot of techniques and memorising steps, such the Tango, will likely give a noticeable increase in intelligence. Whereas the damage caused from violently swinging a head around to Slayer for ten minutes may have the opposite effect.
