Embodiments described herein generally relate to systems and methods for treatments using xenon and hydrogen. In some embodiments, liquids comprising xenon and hydrogen are provided. Such liquids may be useful, for example, for the treatment of animal and human diseases, for improvement in athletic performance, for the enhancement of the overall health of a subject, or the like. The liquids (e.g., aqueous solutions) and articles described herein may be administered to a subject, e.g., drunk by a subject. Some embodiments relate to liquids disposed within a container (e.g., a sealed container), such that the liquid comprises hydrogen gas and a noble gas dissolved or otherwise contained (e.g., infused) in the liquid. In certain embodiments, the hydrogen gas and/or noble gas may be present in the liquid at a particular concentration (e.g., a physiologically relevant concentration). Advantageously, the compositions, articles, and methods described herein may provide liquids containing hydrogen gas and a noble gas that are shelf-stable (e.g., maintain a relatively stable concentration of hydrogen gas and/or noble gas(es)) for relatively long periods of time (e.g., at least 7 days).
