The Blue Lagoon 〈WORKING〉
Psoriasis is a chronic autoimmune condition that causes rapid skin cell turnover, resulting in painful, scaly plaques. Standard treatments include UV light and corticosteroids. At the Blue Lagoon, patients undergo a three-week course of daily soaks in the geothermal water, combined with phototherapy.
The Blue Lagoon closed repeatedly between 2023 and 2024. For weeks, the area was a military-style exclusion zone. Workers built massive defensive berms—walls of compacted rock—to divert potential lava flows away from the power plant and the spa. Remarkably, the facility survived. When the eruption subsided, the lagoon reopened, but the access road now winds past steaming, freshly congealed lava that flowed across the parking lot just months prior. The Blue Lagoon
The contrast is immediate. The air might be -5°C (23°F) with Arctic wind, but the water is a warm embrace. Steam rises in thick curtains, obscuring the distant view of the Eldvörp crater row. The floor is uneven sand and lava rock; you must wear aqua shoes or tread carefully. Psoriasis is a chronic autoimmune condition that causes
By the 1980s, locals noticed something peculiar. People with skin conditions like psoriasis who bathed in the runoff found their symptoms drastically reduced. In 1987, the first makeshift changing rooms were built, and the Blue Lagoon was officially born. It took a decade of legal battles and environmental assessments, but by 1999, a formal spa facility opened. The power plant is still running; you can see its steam stacks rising behind the lagoon’s changing rooms. The Blue Lagoon is not a thermal spring in the traditional sense (like the geysers of Haukadalur). It is a engineered ecosystem. The water is a unique cocktail: 70% seawater and 30% freshwater, heated by the plant to a comfortable 37–40°C (98–104°F) year-round. The Blue Lagoon closed repeatedly between 2023 and 2024
It is also undeniably magical. To float in that milky water, face covered in white mud, watching steam rise into the Arctic air while a power plant hums quietly in the distance, is to witness a strange harmony. It is the most beautiful puddle of industrial runoff on Earth.
There is a profound irony: Climate change and glacial melt threaten Iceland’s other wonders (the glaciers of Vatnajökull are receding), but the Blue Lagoon is thriving. It consumes 1,000 liters of water per second, drawing from aquifers that are replenished by rainfall and glacial melt. Some environmentalists worry that the expanding spa industry is diverting geothermal water that could heat homes or generate electricity.
