History of the Blue Lagoon

The Blue Lagoon began as a pool of wastewater from the Svartsengi geothermal plant in 1976. Few Icelanders, if any, had any desire to bathe in it, as the idea of bathing in wastewater from any kind of power plant was considered crazy. 

This all changed in 1981 when an employee of the plant called Valur Margeirsson asked for permission to bathe in the pool. He had a skin condition, known as psoriasis which prevented him from bathing in Iceland's famous hot springs with others. Initially, he was met with resistance, and it seems very unlikely that he would have been allowed to do it today, but he kept asking his bosses and was eventually given permission to bathe in the pool.

Remarkably, bathing in the lagoon didn’t do him any harm and he quickly noticed that his skin condition miraculously improved after the swim. News of the lagoon’s healing powers quickly spread, leading the Icelandic authorities to open public bathing facilities aimed at people with skin conditions in 1987.   

The Lagoon’s popularity skyrocketed in the next few years, with thousands of Icelanders flocking to it each year. Its stylishness meant that the facilities were constantly upgraded, transforming it from the original wastewater pool into the world-class spa facility that everyone knows and loves today.

Is the Blue Lagoon natural?

The short answer is no – the long answer is sort of. The Blue Lagoon is created by runoff from the nearby Svartsengi Geothermal Plant. Although that might sound a bit unpleasant, rest assured, it most definitely isn’t!   

Svartsengi creates energy by pumping water deep into the ground, which is then geothermally heated and used to turn on turbines that create electricity. Once it has created totally eco-friendly energy, the water is then pumped into the Blue Lagoon.

The Geothermal Plant is located in the center of a lava field, giving it easy access to the subterranean geothermal lava flows needed to create power. The porous lava rock acts like a filter, removing impurities from the water and filling it with minerals such as silica and sulfur.

The Blue Lagoon’s potential curative properties were first noticed by a few Icelandic visitors with psoriasis. It was then used as a dedicated healing facility for people with the same condition and was so successful that doctors in Iceland regularly prescribe it. So, although the skin healing properties of the lagoon are not 100% certain, the overwhelming evidence seems to point to the benefits.   

People theorize that its waters are good for our skin, because of the dissolved minerals in the water, the blue-green algae that live in the water and a type of bacteria that has only been found in the lagoon.   

Is the Blue Lagoon clean?

Yes, the waters in the Blue Lagoon are refreshed every 48-hours and every visitor is required to shower naked (in a private stall) before entering.
