The concept actually originates from Japan and was discovered by Professor Shigeo Ohta from Nippon Medical School, an internationally renowned hydrogen medicine researcher known as the "founder of molecular hydrogen medicine."
In 2007, Professor Ohta published a paper in the internationally renowned medical journal Nature Medicine, "Hydrogen acts as a therapeutic antioxidant by selectively reducing cytotoxic oxygen radicals."
In this paper, one of the points discussed by Professor Ohta is that 2% hydrogen gas provides protection against cerebral ischemia-reperfusion injury and reduces the area of cerebral infarction.
Subsequently, numerous medical studies have adopted the 2% hydrogen gas concentration for various disease intervention experiments and research, achieving certain results.
The Japanese Ministry of Health, Labour and Welfare (the main department responsible for medical, health, and social security in Japan) has even classified the inhalation of 2% hydrogen gas as a medical treatment, recognizing it as an adjunct therapy for diseases. Currently, it is used in Japan for protecting against brain damage following cardiac arrest.
How can "2% hydrogen inhalation" be achieved?
This involves a basic concept: generally, the total amount of air our lungs inhale per minute is 5-8 liters. Taking an average value of 6 liters as an example (some people have larger lung capacities, some smaller, and height and weight vary for everyone, so this is only an approximate average), with a hydrogen inhalation machine that produces a flow rate of 300 milliliters per minute, during exhalation, no air is inhaled through the nostrils, and during inhalation, it is not 100% absorbed. Therefore, we can roughly estimate that 120 milliliters of hydrogen enter our lungs per minute. Based on this ratio, 180 milliliters of the 300 milliliters of hydrogen might be wasted, with an efficiency of approximately 40%.
The actual amount of hydrogen inhaled depends on each person's breathing patterns (such as frequency and lung capacity), breathing posture (sitting or lying down while inhaling hydrogen), and breathing habits (diaphragmatic or chest breathing), making accurate calculations difficult. It can only be roughly estimated that with a hydrogen inhalation machine producing 300 milliliters of hydrogen per minute, about 2% of the hydrogen might enter the lungs through nasal inhalation. This is a concept used in practical applications.
But currently, there is no specific consensus on the most effective volume, and as manufacturers, we can only provide equipment based on the specific needs of our customers.
The hydrogen health industry is still very new, and the understanding of hydrogen medicine depends on the level of awareness that buyers currently have. Some customers believe that 300ml/min is sufficient, while others think higher output is better, as they refer to different literature, recommendations from relatives, friends, or doctors.
