"Plateau phenomenon" is a concept in educational psychology, which refers to a temporary pause or decline in the process of learning or skill formation. On the growth curve, it shows that it does not rise or fall at a certain level, but after breaking through the "plateau phenomenon", we can see that the curve continues to rise. There are countless examples of this "plateau phenomenon" in real life.

brief introduction

Plateau phenomenon is a natural physiological reaction of human body to adapt to the changes of air pressure difference, low oxygen content and dry air caused by altitude. When the altitude reaches about 2700 meters, the plateau phenomenon will appear.

The symptoms of altitude sickness are headache, shortness of breath, chest tightness, anorexia, low fever, dizziness and fatigue. Some people appear because of low oxygen content: purple lips and fingertips, lethargy, hyperactivity, insomnia and other different manifestations. Some people appear because of dry air: rough skin, chapped lips, bleeding nostrils or blood clots.
