With regard to whether hydrogen inhalation can cause death, there is also insufficient evidence to suggest that this method is harmful. However, if not used properly, inhaling hydrogen can lead to a number of potential risks and side effects, such as allergic reactions, breathing difficulties, and explosions. Therefore, if you want to try hydrogen inhalation to treat your illness, it is recommended that you do so under the guidance of a medical professional and follow the proper usage and precautions. At the same time, it should also be noted that any kind of treatment has its limitations and scope of application, and its efficacy should not be over-exaggerated, nor should its potential risks and side effects be ignored.
