airbreath® oxygen reduces the symptoms of fatigue that occurs in drivers, which is a different form of fatigue (mental), featuring reduced motivation, drowsiness, lack of focus, impaired vehicle control (e.g. speed variations, yawing). Even more dangerous is that drivers are unaware of the extent of their tiredness and keep driving. airbreath® oxygen is also used to prevent hangover. If used during alcohol consumption, the oxygen will generally prevent morning hangover. It is a known fact that WWII pilots used oxygen to treat hangover after all-night partying and drinking. Alcohol reduces blood oxygen, thus causing hangover. A few breaths of airbreath® oxygen replenishes blood oxygen levels.
