Healthy people should not routinely take oxygen without hypoxia. In this regard, many studies have been conducted abroad, and the results show that as long as the oxygen saturation is greater than 94% (an index reflecting whether there is hypoxia in the blood), it will do harm to the human body.
Many completely healthy people take oxygen inhalation as a "health care" measure, and even there are many "oxygen bars" in the streets. Some students who are preparing for the senior high school entrance examination and college entrance examination will take oxygen before the exam. Despite the lack of such research, it is inferred from the above research results that it will not be beneficial.

The State Food and Drug Administration reminds that the product should be used according to the daily use time and flow of prescriptions under the guidance of doctors, so as to reduce the risks caused by improper selection of indications. At present, there is no evidence that oxygen inhalation has health care effect on normal people. On the contrary, improper oxygen inhalation may cause harm to human body. In addition, consumers should buy and use under the guidance of doctors, and should not blindly buy and use.
