LETTER: Inhaling oxygen not a proven stress reliever
August 29Editor, So-called oxygen bars often tout health benefits of providing additional, and even " 100 percent pure-grade medical oxygen" to the body to help body and mind by cleaning the system of toxins, increasing energy and stamina, and reducing stress. While one cannot argue with the power of suggestion and the subjective benefits of things that can make you feel better, there is no evidence that healthy people can benefit from inhaling oxygen other than the 21 percent of oxygen found in the air we breathe.
