Because it takes a certain amount of time to absorb hydrogen, it is best to inhale it during sleep, so that it does not affect life and work. Of course, you can absorb hydrogen while watching TV, reading, studying, and sedentary work.

As a daily health care, inhalation for 1-2 hours a day can achieve the effect, but for critical and severe diseases such as tumors, rheumatism, etc., long-term inhalation is required. Many elderly people who have already developed symptoms of Alzheimer’s also need to absorb hydrogen for a long time every day, at least 4-6 hours every day

When diving underwater, divers can breathe high-pressure and high-concentration hydrogen continuously for 14 days. Hydrogen has been used as a diving gas for more than 80 years, and no side effects have been found so far, so there is no problem in inhaling hydrogen for a long time. What needs to be reminded is that no matter who absorbs hydrogen, there needs to be an adaptation process. The hydrogen absorption time should be increased from 30 minutes as much as possible. After the hydrogen is inhaled, the blood circulation will increase. If the elderly are not well, they will experience discomfort, the increase in hydrogen absorption time should be as slow as possible.

Hydrogen is a combustible gas. The concentration range of combustion and explosion in the air is 4-74%, which is a very large range. In order to avoid the risk of combustion and explosion, we recommend that the concentration of inhaled hydrogen is about 2%. Japan defines 2% hydrogen inhalation as a medical treatment for "cardiac arrest". This concentration will not burn and explode even in an open flame environment and can be used with confidence. If you inhale hydrogen within the explosion range, you need to prevent sparks and static electricity, and use it with caution.

There is no danger of combustion and explosion when the hydrogen concentration is below 4%, and it is safer to use. Scientists have studied and compared various concentrations below 4%, and found that the inhalation of 2% concentration of hydrogen has the best effect on the disease, so 2% is generally recommended for population use. The Ministry of Health and Welfare of Japan also included the inhalation of 2% hydrogen concentration as a medical method in the medical device outline. The flammability and explosiveness of hydrogen were mentioned earlier,in order to avoid risks, if there is no evidence to prove how much hydrogen concentration is required to be effective, we generally propose the safe range of inhalation concentration is below 4%. If the same inhalation time shows that the inhalation effect of higher concentration of hydrogen is indeed better, we recommend extending the hydrogen inhalation time to make up for it, which is called "time for safety and time for effect".

Under normal circumstances, by electrolyzing pure water, hydrogen with a purity of more than 99.9% can be obtained. We set the gas flow rate of the hydrogen absorption machine to be 300-500 ml/min. For adults weighing about 60-80 kg, according to the calculation formula of breathing gas, the concentration of hydrogen that enters the body with each breath is between 1.5-2.5%, which is in line with the concentration found to be effective for disease recovery. All in all, a device with a hydrogen production flow rate of 300-500ml per minute can achieve therapeutic hydrogen inhalation. Properly prolonging the hydrogen absorption time on the basis of safety can achieve better disease improvement effects.

Yes, according to research reports, hydrogen can improve memory and prevent brain aging, which is of great help in improving the learning ability of young people.

Studies have shown that hydrogen inhalation can calm the nervous system, relieve stress, resist depression, and significantly improve the sleep problems of cancer patients. In the crowd application, many sub-healthy people report that their sleep quality has been improved after inhaling hydrogen and drinking hydrogen water.

Inhalation of 2% hydrogen concentration is effective for cerebral ischemia. Animal and population studies have shown that acute cerebral ischemia is a clinically critical and life-threatening illness. There are population studies that prove that hydrogen inhalation as an auxiliary means can reduce the risk of death from cerebral ischemia. But what needs to be reminded is that the current hydrogen absorption equipment is not a medical device and cannot be used legally in clinical emergency treatment. It is hoped that in the future hydrogen absorption products can obtain medical device license, so that hydrogen can play a role in clinical emergency treatment.

As mentioned earlier, because the hydrogen inhaling equipment has not been approved for medical treatment, it cannot be used in hospital clinics, but it can be used as a means of health preservation during the rehabilitation period. It is recommended to use hydrogen inhalation equipment after the patient’s condition is stable. The initial hydrogen inhalation time should be as short as possible, and the hydrogen inhalation time should be increased slowly, so as to give the patient a process of adaptation. Inhalation of hydrogen can promote the recovery of brain function and improve the quality of life of patients. In addition, the biggest risk of stroke is the second stroke in the later stage. Hydrogen can prevent arteriosclerosis, improve the health of the cardiovascular and cerebrovascular system, and prevent re-stroke, which is a very goodmethod of stroke rehabilitation.

Hydrogen inhalation can help patients with myocardial infarction improve heart function and reduce the problem of cardiac malformation in the stable phase after rescue. As with stroke, because hydrogen inhalation products have not yet entered the clinical treatment system, it is recommended to use them appropriately during the recovery period after discharge from the hospital. Remind everyone that the occurrence of myocardial infarction indicates that the patient’s blood vessel problems are more serious, because hydrogen inhalation will promote blood circulation, so when patients with myocardial infarction start to inhale hydrogen, they should pay attention to whether they feel uncomfortable. To ensure safety, start from the minimum dose and increase slowly

Some population studies have found that hydrogen inhalation can reduce the inflammatory response during haze exposure and protect the respiratory system, which to a certain extent can reduce the chance of lung cancer caused by fog stimulation. For respiratory diseases, there are currently no good preventive measures, and hydrogen inhalation may play an important role.

Inhalation of hydrogen can prevent the occurrence of chronic obstructive emphysema caused by smoking and improve the respiratory function of patients. The effect of hydrogen inhalation on respiratory diseases (including chronic obstructive pulmonary disease, asthma, etc.) is a hot topic of hydrogen medical research and attention. The current ideal case found that the lung function was significantly restored after long-term hydrogen inhalation (6 hours a day, 2% concentration) for 2 consecutive years

Alzheimer’s disease is a kind of brain aging disease. The early manifestation is the aggravation of forgetting phenomenon, and memory disorders often appear. Once senile dementia is discovered, it is in the middle and late stages. The disease develops quickly and cannot take care of oneself. In the later stage, people need to take care of them 24 hours a day, which causes a huge burden on society and families.

Studies have shown that hydrogen can alleviate brain aging, prevent the occurrence of Alzheimer’s, and can also curb the deterioration of Alzheimer’s disease. Long-term inhalation may also reverse the severity of senile dementia, improve the quality of life of patients with senile dementia, and reduce family and social burdens.

The snoring mentioned here refers to the sudden stop of breathing during sleep, referred to as "sleep apnea". This situation can cause hypoxia in the brain and body organs, and there is a risk of sudden death. Many studies have confirmed that hydrogen can improve various organ damages (heart, brain, kidney, etc.) caused by hypoxia. Evidence from population studies has also found that the number and duration of sleep apnea can be reduced after inhaling hydrogen every day.

The reasons for the formation of cysts, nodules, and polyps in the human body are more complicated, and are related to heredity, environment, diet, endocrine, etc. Some nodules and polyps may be at risk of malignant transformation and require long-term follow-up observation in the hospital. Many people are nervous about the results of these tests. The causes of these problems are complicated. There is no relevant research evidence yet, but there are cases that prove that lung nodules, breast nodules, thyroid nodules, gallbladder polyps, intestinal polyps, etc. shrink or even disappeared after long-term hydrogen inhalation and drinking hydrogen water. Based on the safety of hydrogen, it is recommended to stick to long-term use hydrogen, at least the probability of these problems will be greatly reduced.

Studies have confirmed that hydrogen can inhibit the formation of kidney stones and reduce the damage of stones to the kidney, mainly for preventive effects. Small kidney stones may be discharged by drinking a lot of hydrogen water. If there are large kidney stones, it is recommended to go to the hospital for shock wave lithotripsy and discharge. Hydrogen has a better effect on prostatitis. This is evidenced by research. There are many application cases for prostatic hypertrophy. It is proved that if you insist on inhaling hydrogen and drinking hydrogen water every day, the problem of prostatic hypertrophy is improved and the degree of pressure on the urethra is reduced. So it is recommended that people with enlarged prostate can try it.

No, although the concentration of hydrogen inhalation is higher than that of drinking hydrogen water, drinking hydrogen water can regulate the intestinal flora and prevent many intestinal diseases, which is irreplaceable by hydrogen inhalation.

Hydrogen inhalation can reduce the side effects of tumor radiotherapy and chemotherapy. Recent animal experiments have found that long-term hydrogen inhalation can inhibit the proliferation and metastasis of tumor cells. We try to inhale hydrogen and drink hydrogen water for cancer patients. The goal is to extend their survival period and improve their quality of life. It cannot be said that hydrogen has a therapeutic effect on tumors, but hydrogen should be an effective aid in the process of tumor treatment. Reduce the pain caused by cancer and prolong life as much as possible.
