What should I pay attention to when traveling to Tibet? Especially in terms of personal safety.

Tibet's special plateau environment will have a certain impact on the body. Therefore, before traveling to Tibet, you must go to the hospital for a physical examination, and you can only leave if there is no problem with your heart and lungs. People with heart disease, severe anemia, asthma and high blood pressure should not travel to Tibet.

Matters needing attention on the way to Tibet:

(1). Oxygen and drugs to prevent and treat acute altitude sickness, such as nifedipine (also known as nifedipine) and aminophylline, should also be prepared as much as possible, as well as drugs, antibiotics and vitamins to prevent and treat colds, just in case.

(2) Due to the cold climate in the plateau and the large temperature difference between day and night, we should pay attention to preparing enough warm clothes to prevent colds. Both colds and respiratory infections may cause acute altitude sickness.

(3) If you have severe symptoms of altitude sickness on the way to the plateau, you should treat it immediately and take aminophylline or nifedipine 20 mg in time. In severe cases, oxygen should be inhaled. In case of severe chest tightness, severe cough, dyspnea, pink foam phlegm cough, or slow response, indifference or even coma, in addition to the above treatment, you should go to a nearby hospital for rescue as soon as possible, or transfer to a lower altitude area for treatment and recovery as soon as possible.

(4) Because it takes a long time to enter the plateau by car, the accommodation conditions on the way are poor, and the physical strength is high, in addition to the above items, water or drinks and delicious and digestible food should be prepared to replenish the necessary water and heat in time.

About altitude sickness:

Traveling to the plateau is at risk of altitude sickness symptoms. Generally, mild altitude sickness will occur at 1, 200 to 1, 800 meters, while severe symptoms will not occur less than 2,700 to 3,000 meters. Whether your past physical condition can accept the challenge of the environment may need to consult your doctor to explain whether you have important organ dysfunction; Avoid common respiratory diseases such as colds and fever before departure; Save a lot of physical strength.

According to statistics, 1% of tourists who fly to Lhasa will have altitude sickness, so it may be necessary for tourists to take some preventive drugs. Prevention includes taking some Chinese patent medicines, such as American ginseng and rhodiola. At present, western medicine is considered to be effective, but some people will have headaches and other side effects, so it should be used under the guidance of doctors. On the plateau, some common symptoms can be solved: Fenbid can treat headache, and vitamin B6 can treat nausea and vomiting. If you still feel unwell, you should go to the hospital for treatment.

After entering the plateau from the plain area, the adjustment changes of the human body are mainly manifested in the following aspects:

(1). Pulse (heart rhythm) frequency: The normal pulse in plain area is 72 beats/min, which can be increased to 80 ~ 90 beats/min when you first arrive at the plateau, and it can reach 100 beats/min for individuals, and can be recovered after living for a period of time.

(2). Breathing: When the respiratory system is slightly hypoxic, the first manifestation is deepening and accelerating breathing, and the breathing frequency is further accelerated with the aggravation of hypoxia, and people feel chest tightness and shortness of breath. After adaptation, it will gradually return to its original level.

(3) Blood pressure: normal systolic blood pressure110 ~120mmhg and diastolic blood pressure 0 ~ 80mmhg in plain area. After entering the plateau for the first time, due to the influence of vascular receptors and body fluids, blood vessels such as skin and abdominal organs contract and blood pressure rises, thus ensuring blood supply to coronary arteries and cerebral vessels. It will return to normal after adaptation.

Other considerations:

1, medicine box. Passengers are advised to prepare two small medicine boxes, the big one in the backpack and the small one to carry with them.

The basic drugs are: Bilitong, aspirin, Ganmaoling, Ganmaoqing, Niuhuang Jiedu tablets, cough drops, Houyan pills, vitamin C pills, Baihua oil, gauze, stomach medicine, eye drops, anti-inflammatory drugs, which are used to treat colds, headaches (recommended: gabapentin) and gastrointestinal drugs; American ginseng buccal tablets and jinshi erkang are very helpful to the body.

2, sunglasses and sun hats, strong sunlight and ultraviolet rays on the plateau will hurt the eyes, especially in the Himalayas.

3. Sunscreen, lotion and lip balm are also necessary. The air on the plateau is dry and the sun is strong, so that at Gongga Airport, tourists with burned cheeks and noses can often be seen leaving Lhasa.

4. About contact lenses: Tibet has a lot of dust and poor sanitary conditions. Actually, it is not appropriate to wear contact lenses. If you want to wear it, consider using disposable lenses. Lhasa also sells imported contact lenses, and the price is similar to that of the mainland.
