After four years of hiking in sneakers, I finally went to the plateau. I was so excited, but I had to be prepared to avoid altitude sickness first.

As the altitude rises, the oxygen content in the air will gradually decrease. When the altitude rises to 3500 meters , the oxygen concentration will drop to 66 at sea level. %; When the altitude rises to 5400 meters , the oxygen concentration drops to 52%.

Then, The human body will undergo a series of reactions to adapt to the decrease in oxygen concentration. :like Heartbeat , Increased breathing rate , along with this, Increased red blood cells , Increased capillaries If the climber ascends slowly, the body has ample time to complete these changes; Rapid ascent in altitude , the body will not have time to complete these adaptations, and the human body will appear Headache , Difficulty sleeping And other symptoms, which is what we often call altitude sickness.

Everyone may develop altitude sickness at different altitudes when going to the plateau. Some people will start to develop altitude sickness above 3,000 meters, and some will not develop altitude sickness until 3,500, 4,000 or even 4,500 meters. The degree of the reaction will also vary from person to person. Different, different.

High altitude sickness is not scary, what is scary is the fear of altitude sickness.

The best way to prevent high fever is to stay calm. When you are scared, nervous or too excited, the guy with high fever will find you and take advantage of you.

Don’t drink alcohol, eat spicy food, don’t be too excited and have a good rest before departure.

Friends who have fitness habits should stop exercising half a month before traveling.

Drink plenty of water during the trip to allow your body to adapt to different altitudes through faster metabolism.

You can prepare some necessary medicines, such as headache powder, which can reduce the headache symptoms caused by altitude sickness. Aspirin powder can also have the same effect.

Don't be afraid of high reaction, and don't underestimate high reaction. If you don't have high reaction once, it doesn't mean you won't have high reaction every time. When hyperreflection occurs, it is even more important to adjust your mood and take remedial measures. When severe hypersensitivity occurs, drink high-concentration glucose immediately, which can take effect in a short time. If necessary, be sure to retreat in time and don't show off.

In short, when going to the plateau, you should relax and return lightly, so as not to be caught by the high-altitude devil!
