Aire is caused by leaving a hot environment and entering a very cold one. There are two forms-childhood (causes ear ache) and adult (muscular spasms or facial paralysis). The treatment for childhood aire is to blow warm smoke into the ear or to form a paper cone, place the point into the ear then light the outer edge so that warm air enters the ear. "Cupping" with a ventosa is used for adult aire. The cup is heated and deoxified with a match or candle, then placed on the affected area. The vacuum in the cup causes the skin to swell and the knotted muscles to loosen up. A variation on "cupping" in certain cultures is "coining."
