The Blue Lagoon is a geothermal spa located in a lava field near Grindavík, Iceland.
The water's milky blue shade is due to its high silica content, forming a soft white mud on the bottom of the lake which bathers rub on themselves. The salts and algae in the water and mud help restore skin and protect it while the heat of the water is great for the cardiovascular system.
Contrary to common belief, the lagoon is man-made:
"The water is a byproduct from the nearby geothermal power plant Svartsengi where 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 water heating system. Then the water is fed into the lagoon"
Sadly for us, the UK doesn’t have such picturesque outdoor lagoons, but you can reap similar benefits using our BAVE Soak and restorative Salts.
