the truth:

For healthy people, the oxygen content in the air is sufficient. Except for some special patients who need oxygen, ordinary people do not need to breathe oxygen. Some users' feelings of "refreshing after breathing oxygen" circulating on the Internet are probably just psychological effects.

The idea that "oxygen inhalation can refresh the mind and improve intelligence" is not only without scientific basis, but may even cause certain negative harm to the user's body. Long-term high-flow oxygen inhalation may lead to oxygen poisoning, causing users to experience adverse symptoms such as nausea, chest pain, vomiting, and more serious gastrointestinal reactions. In extreme cases, it may even cause certain damage to brain cells, and oxygen inhalation may lead to a decline in body function.

Experts say that consumers should choose to buy oxygen generators based on actual needs, and should not blindly follow the trend, let alone expect to refresh children facing exams by breathing oxygen. When you feel tired, you should stop and get enough sleep. Only by getting enough sleep can you better improve your learning and work efficiency.
