I could only hear the sound of my breathing. I was in a daze and soon fell asleep. After that, my brain seemed to be restarted and I had a clear mind.”Dai from the Jiangxi hospital reminded the public that inhaling oxygen in the hyperbaric chamber is not suitable for everyone and a doctor should be consulted.“People with emphysema pulmonum, tympanitis and serious hypertension are forbidden from using this service,” said Dai.“I take a cautious attitude about this trend, and that students and parents chase the oxygen inhalation and regard it as some kind of magic for gaokao preparation,” added the doctor.Two students playing basketball.

They just serve as a psychological placebo. Instead of relying on those external things, it is better to adjust your daily routines,” said Wu.It is estimated over 13.2 million students will attend the gaokao test this year, a slight drop from that of last year.
