Is it hot in Tibet now? Ask god for help

I hope these can help you! ! Tibet is located on the Qinghai-Tibet Plateau, known as the "roof of the world", with an average elevation of more than 4,500 meters and a distinctive climate. Generally speaking, the plateau has strong solar radiation, long sunshine time, large temperature difference between day and night, low temperature, less accumulated temperature, clean air and good transparency. In terms of regional characteristics, the climate in southeast Tibet is mild, with an average temperature of 8℃ and 0℃ in northern Tibet. Lhasa is located in the middle of Tibet, with no severe cold in winter and no heat in summer. It is a famous "Sunlight City". Traditionally, March to 10 is the best season to enter Tibet. At the same time, due to Tibet's high altitude, windy, dry, high light intensity, abnormal gravity, thin air, low air pressure and little oxygen, the oxygen content in the air in winter is only 70% of that in the mainland, and it is as high as 80% in summer. These will bring more or less altitude sickness to people who have just arrived at the plateau, but as long as they pay attention to rest, all the bad conditions will soon return to normal. The prevention and treatment of acute altitude sickness first arrived at the plateau. Scientists say that the altitude above 3000 meters is plateau. Because when the altitude reaches this height, its climatic characteristics (such as hypoxia, hypoxia, high radiation and high cold, etc. ) is obviously different from that in the plain. When people come to such an environment, they must go through a series of adjustments before they can adapt. Therefore, people who have just entered the plateau, even those who live in the plateau, should guard against the occurrence of acute altitude sickness from many aspects when they return to the plateau from the plain. 1. People with the following diseases should not enter the plateau. If you have never been to the plateau, you must have a strict physical examination before entering the plateau. If you find patients with heart, lung, brain, liver and kidney diseases, severe anemia or hypertension, please don't blindly enter the plateau. If it is just a general disease, you must take necessary preventive measures in advance, such as carrying oxygen with you. Precautions after arriving at the plateau When you first arrive at the plateau, everyone will feel different degrees of chest tightness, shortness of breath, difficulty breathing and other hypoxia symptoms. But that doesn't mean you can't adapt to the plateau. If you can protect yourself correctly, the above symptoms can generally be improved or disappeared after 5-7 days. People often advocate oxygen inhalation to relieve discomfort. Of course, oxygen inhalation can temporarily relieve chest tightness, shortness of breath, dyspnea and other symptoms, but after stopping oxygen inhalation, the symptoms will reappear. This has delayed the time to adapt to the plateau. We believe that if the above symptoms are not serious, especially when resting, it is best not to take oxygen, so that you can adapt to the plateau environment quickly. Just entering the plateau, don't overeat, so as not to increase the burden on the digestive organs and make them adapt to this environment well. It's best not to drink or smoke. Eat more vitamin-rich substances such as vegetables and fruits. However, it must also be noted that if the above symptoms become more and more serious after entering the plateau, especially during rest, you should immediately take oxygen and go to the hospital for treatment. Prevent the adverse consequences caused by "acute high altitude pulmonary edema". When you first arrive at the plateau, you shouldn't walk very fast, let alone run, let alone do manual labor. When you first arrive at the plateau, you should prevent colds caused by catching cold. Cold is one of the main causes of acute high altitude pulmonary edema.
