Lhasa is a mysterious existence, which is described as a place "is being rendered and will continue to be rendered; has been interpreted but has not been completely interpreted yet." Whether it is the Potala Palace, the Jokhang Temple, or the Barkhor Street, Norbulingka, there is always a place that can directly grab you deep down your heart and become the home of your soul.
When you first travel to the Tibetan Plateau, most people will feel different levels of hypoxia such as chest tightness, difficulty breathing or other symptoms. But this does not mean that you cannot adapt to the high altitude environment. If you can adjust yourself properly, the above symptoms can generally be improved or disappear in 2~3 days.
If you are flying to Tbet, the symptoms of a general mountain sickness will occur in 12 to 14 hours. Therefore, when you first arrive in Tibet and don’t feel very well, please rest in bed instead of taking any intensive exercise. Otherwise, it takes more time to adapt to it.
People often use oxygen supplement to relieve chest discomfort. Oxygen inhalation temporarily relieves chest tightness, shortness of breath, difficulty breathing, etc., but the symptoms reappear after stopping oxygenation, which actually delays the time to adapt to the high altitude environment. If the symptoms of hypoxia are not very serious, oxygen inhalation is not recommended, which will help you to adapt to the altitude environment faster. A mild altitude sickness will get better without treatment and the oxygen inhalation may become an addiction.
After entering Tibet, you should eat more carbohydrates, digestible foods and drink plenty of water to keep your body hydrated. Please do not eat too much at night nor alcohol drinking and smoking. Foods which are rich in vitamins such as fruits and vegetables are recommended. Please try not to do too much and try to eat and rest regularly. During the first few days when you just arrived in Tibet, Please don't take frequent shower to prevent yourself from catching colds. Colds are often the main cause of acute high altitude pulmonary edema (which is not easy to heal under hypoxic conditions).
During your stay in Tibet, please don’t take too many activities and carry too much stuff. Please slow down with everything and walk slowly. You can gradually increase the amount of activity after a week.
