The standard air we breathe has about a 20.8% concentration of oxygen, and while our bodies are set up to function well from this percentage, advocates of the oxygen bar say that a periodic breath of “fresh air” can boost our immune systems, reduce stress and even improve mood. Oxygen bars are known to alleviate the effects of headaches, migraines, hangovers, sinus infections, and even altitude sickness. Oxygen in its purest form may help you to feel more alert, increase your ability to concentrate, and give you a general feeling of relaxation. When you have symptoms such as hangovers, headaches, fatigue, jet lag, these are all caused because your body is depleted of oxygen.
