I arrived in Lhasa yesterday, and I have no altitude sickness today, so I won't be tired after running. What happened? I'm not Tibetan! !

Hello, in daily life, many people who live in the plain have almost no discomfort when they reach the height of 3 thousand meters. When it reaches about 4 kilometers, tinnitus, dizziness, headache, chest tightness, rapid heartbeat, vomiting and other reactions will generally occur, and some people will be accompanied by low fever. These are the characteristics of altitude sickness. If altitude sickness is relatively small, you can rest more, drink more water and exercise less, and the symptoms will disappear and weaken after a period of rest. You can take some drugs to relieve altitude sickness: Rhodiola, Omer blue tablets, glucose solution, etc. Severe altitude sickness, take proper oxygen and go to the hospital in time. The symptoms of altitude sickness can be eliminated within 1-2 days for people with strong adaptability to altitude, and it takes 3-7 days for people with weak adaptability. Whether there is altitude sickness or not, it is best not to run in the plateau, just eat seven points full, keep calm, don't be overjoyed, and especially avoid shortness of breath. Altitude sickness is not a serious disease. If you pay attention to rest and diet, you will heal yourself in about a day or two. This requires a higher psychological quality and an optimistic and peaceful attitude. If you are too nervous and afraid, your brain will be deprived of oxygen, but it will get worse. Try not to press your heart when you sleep. You can sleep half or side.
