The Blue Lagoon geothermal spa is  one of the most visited attractions in  Iceland. The steamy waters are part  of a lava formation. The warm waters  are rich in minerals like silica and  sulphur and bathing in the Blue  Lagoon is reputed to help some  people suffering from skin diseases  .The water temperature in the bathing  and swimming area of the lagoon  averages 37–39 °C . The Blue  Lagoon also operates a Research and  Development facility to help find cures for other skin ailments using the  mineral rich water. The lagoon is fed by the water output of the nearby  geothermal power plant Svartsengi and is renewed every 2 days.  Superheated water is vented from the ground near a lava flow and used to  run turbines that generate electricity. After going through the turbines, the  steam and hot water passes through a heat exchanger to provide heat for a  municipal hot water heating system. Then the water is fed into the lagoon for  recreational and medicinal users to bathe in.
