A Hundred Years of Helium

Helium has been a vital part of diving for a century, especially for technical divers. It helps reduce the risk of nitrogen narcosis during deep dives. Helium first gained popularity in the 1920s when the U.S. Navy tested helium-oxygen mixtures, discovering that helium was less narcotic than air. Over the years, divers have continuously improved techniques and tools for using helium, allowing for deeper and safer dives using mixed gases, which include helium. Today, helium is crucial for various diving operations, from recreational to scientific research.
