It is a question whether the average elderly can travel to Tibet.

Yes, you can, but you should be fully prepared.

To travel to the plateau, it is necessary to make necessary medical care and physical hygiene preparations: (1) Visitors entering the plateau from low altitude areas must undergo a comprehensive and strict physical examination. Anyone with serious heart, kidney and lung diseases has high blood pressure! /kloc-patients with severe liver disease and anemia over 0/8 years old are not allowed to venture to travel to the plateau. If you only suffer from common diseases, you must take preventive measures in advance, such as carrying oxygen and drugs with you. Those who have convulsions, severe headaches or coma tendency after entering a certain altitude area should not go to higher areas. (2) Do a good job in the publicity and education of physical health, so that tourists have sufficient ideological and material preparation, establish the determination and confidence to overcome altitude sickness, and eliminate unnecessary mental fears. Generally speaking, you can gradually adapt to the plateau environment in about two or three days, or as many as five to seven days. Symptoms of hypoxia such as chest tightness, shortness of breath and dyspnea will disappear or be greatly improved. Some people use oxygen inhalation to relieve plateau discomfort, which helps to temporarily relieve discomfort, but after stopping oxygen inhalation, discomfort will reappear, delaying the time to adapt to the plateau environment. If the symptoms of hypoxia are not serious, it is best not to take oxygen during quiet rest, so as to adapt to the plateau environment as soon as possible and obtain the ideal tourism effect. (3) adaptive exercise. Before traveling to the plateau, we should carry out sports activities such as climbing mountains, running, playing ball, carrying loads and marching, which can play a positive role in adapting to the anoxic environment. At the beginning of entering the plateau, the activity should not be too intense. The temperature in the plateau is low and changes rapidly with the temperature. It is necessary to change clothes in time, do a good job of keeping warm from the cold, and prevent colds due to freezing. Cold is one of the main causes of acute high altitude pulmonary edema. (4) Adjusting life during plateau tourism. Food should be digestible, nutritious, high in sugar content and contain multiple vitamins. Eat more fruits and vegetables and don't overeat, so as not to increase the burden on the digestive organs. It is forbidden to drink alcohol to avoid increasing oxygen consumption. When sleeping, the pillow should be padded higher, and the semi-lying posture is the best. (5) Drug prevention and treatment. In order to improve the body's tolerance to hypoxia and reduce the incidence of mountain sickness, the main drugs are: compound Radix Codonopsis tablets, compound Radix Astragali and Poria, aptamer, acetanilide, diuretic sulfanilamide, spironolactone, central nervous system stimulants, inhibitors, thiosemicarbazone, nutrients and metabolic hormone preparations. After entering the plateau, the symptoms of altitude maladjustment become more and more serious, so oxygen should be taken immediately and sent to the hospital to prevent the adverse consequences of acute altitude pulmonary edema. It takes about 3-4 days for the average person to adapt to altitude hypoxia. The so-called adaptation here does not mean that your reaction will disappear. You will still feel difficult to move, but the headache and other reactions will be significantly reduced or even disappeared. During the adaptation period these days, even if there is no response at all, don't be strenuous. The consequences of physical overdraft will make you taste the sweetness in the next few hours. Secondly, don't take medicine indiscriminately, not to mention it is easy to take oxygen. It is more "convenient" to drink more water, and pay attention to keep warm and rest.
