These O2 chambers from Japan, without any apparent substantiations, seem to deliver miracles to anyone from the healthy to the sick:
With the recent popularity of O2 capsules rising in Japan, Time World markets its high-pressurized oxygen capsule for injured athletes or lethargic patients. The capsule is now popular among famous athletes such as David Beckham. It is also used in other medical fields like gynecology, osteopathy, and ophthalmology. The increased pressure in the oxygen capsule allows for molecular level oxygen to be dissolved in you blood. When molecular level oxygen enters the blood stream, your metabolism increases and body cells are vitalized. Body fatigue results from the accumulation of lactic acids. By absorbing oxygen, you can reduce the lactic acid level in your body by 40%. When you are busy at work, or overly stressed from pregnancy or intense studying, this equipment can provide you with lots of oxygen and keep your brain from becoming fatigued and oxygen-deprived.
