What is Iceland’s Blue Lagoon?

Iceland’s Blue Lake is a spa whose main attraction is its warm outdoor waters at an average temperature of 39°C all year round. The water of the lake is blue, hence its name, due to the algae that are present in the water and the grayish blue characteristic of silica, one of the main elements contained in the water.

The lagoon welcomes a large number of visitors daily and throughout the year. So it has strict hygiene rules such as showering naked before and after bathing. On the other hand, water renewal is done every 48 hours, so there is constant oxygenation of the water.

History of the blue lagoon

This lagoon has an interesting history because it is not a natural lagoon but an artificial one. It was built in 1976 for the purpose of receiving wastewater from the Svartsengi geothermal power plant.

The geothermal power plant drills into the ground to obtain hot groundwater up to 200°C. Once used to generate electricity, it is used to heat water from the municipal hot water system and finally the water, at a lower temperature, reaches the Blue Lagoon.

Initially the water disappeared by seeping through the porous lava, but silica has clogged the pores over time to form Iceland’s famous Blue Lagoon.

However, despite its origins, there is nothing to worry about! Since it is a water free of chemicals or pollutants. On the contrary, it is rich in natural minerals such as silica, so it has earned the reputation of being very good for the skin.

It is known that the first person who decided to go into the Blue Lagoon, Valur Margeirsson, did it trying to find a cure for psoriasis. He achieved his goal and baptized the lagoon as “Bláa Lónið” in Icelandic which means Blue Lagoon. This happened in 1981 and 6 years later it opened its doors as a public bath for people with skin problems such as psoriasis and similar diseases.

In 1999 it underwent a major transformation and year after year its facilities are improved until it is recognized as a wonderful Spa. Today it attracts visitors from all over the world, even National Geographic included it as one of the 25 wonders to visit in the world.
