While thermal springs are revered for their soothing external use, the practice of drinking this mineral-rich water, known as 'insen' in Japanese, has a long history in some cultures. However, the question of "Is thermal water edible?" has a nuanced answer that depends heavily on the water's source, composition, and processing.

Following the 1995-1996 eruptions of Mt. Ruapehu in New Zealand, scientists recorded elevated fluoride concentrations in nearby water sources, highlighting the potential chemical risks associated with volcanic activity. This raises a critical question: is volcano water safe to drink, or are the natural filtration and mineral content claims just marketing hype?

Over 4.7 million people have been affected by volcanoes globally, with volcanic emissions potentially contaminating water sources. While water near active volcanic events can be extremely hazardous, naturally filtered volcanic water, known for its high mineral content and alkalinity, is a different story. This guide explores whether volcanic water is safe to drink by distinguishing between raw, contaminated sources and commercially bottled products.
