Xenon gas

Xenon is a noble gas and a rare element found in the Earth's atmosphere. Known primarily for its use in lighting, such as car headlights, it is also remarkable due to its properties as an anesthetic. Extracting xenon requires distilling millions of liters of air which makes it quite expensive; a single breath of xenon costs around $60. Despite its cost, xenon is considered an almost ideal anesthetic because it is not metabolized, can be recycled indefinitely, and has no known toxicity. It provides rapid onset and recovery of anesthesia, and is also noted for inducing a strong euphoric effect 1.

Xenon's potential extends beyond anesthesia. It has been investigated for medical uses such as treating PTSD and has sparked interest due to its performance-enhancing properties noted in sports like the biathlon. These uses leverage its unique properties, including its ability to induce euphoria and possibly affect oxygen levels, which could enhance endurance 2.

Xenon therapy is also gaining popularity in certain clinics globally, offering treatment for various ailments. Despite its intriguing applications and benefits, the high cost and scarcity of xenon gas make widespread use challenging 3.
