Tibet has the highest oxygen content in the air in autumn, so tourists are advised to travel to Tibet in autumn. Tibet, located on the Qinghai-Tibet Plateau, is influenced by the Indian Ocean monsoon, with sunny all year round and abundant rain in summer. Due to the high altitude in Lhasa, the annual average oxygen content in the air only accounts for 64.3% of the oxygen content in the plain area. According to the analysis of air oxygen content in Lhasa by Lhasa Meteorological Bureau,1-February, the air oxygen content only accounts for 63-64% of the air oxygen content in the plain area; From March to April, the oxygen content is 64-65%; May-June, 65-66%; July, August, September and1October are the seasons with the highest oxygen content in Lhasa, with an average of 66.3%, and1October is close to 67%. From 1 1 month, the oxygen content in the air gradually decreased, and1February was the lowest in the whole year, only 62.7%. The landlord should be worried about altitude sickness caused by lack of oxygen. In fact, the probability of altitude sickness in high altitude areas such as Tibet is less than 50%. There are two points to prevent altitude sickness: 1 physical examination before traveling to the plateau. If there is a disease that prohibits plateau travel, don't go first, and then go when you have a cold and fever. A healthy mood, you can regard it as an experience and a feeling. Altitude sickness is not terrible. Many people spread it through hearsay, and they had psychological fear before going. In fact, a good mood is more effective than drug adjuvant therapy. The uncomfortable places of altitude sickness are: the elevation, increased intracranial pressure, which oppresses the cranial nerves, causing headache, nausea, dizziness and, most seriously, insomnia. A person has basically not slept for 48 hours in a row, not to mention being sore, weak and uncomfortable on the plateau and plain. The experience we got from working here is: prepare headache powder and painkillers, and take them when you feel headache and can't sleep normally. The effect is immediate, and you usually get used to it after three times. Although these drugs are not easy to take often, they are all approved by Chinese medicine, and this dose is harmless to the human body. A little advice, I hope it can help you, and I wish you a happy trip to the plateau! -Newton under Bodhi
