When more and more people enter Tibet by plane, train or car, experts advise tourists to make proper preparations before entering Tibet.

First of all, from the decision to travel to the plateau, we must strengthen anaerobic exercise. A lot of strenuous exercise can enhance the body's tolerance to hypoxia. Secondly, prepare some commonly used drugs. The plateau climate is cold and the sanitary conditions are limited. Tourists are prone to catch a cold and gastroenteritis, so they should take corresponding medicines. At the same time, the diuretic acetazolamide must be prepared, which is the main drug to prevent altitude sickness, can eliminate paroxysmal nocturnal apnea, improve the quality of nighttime sleep and relieve the headache when getting up in the morning. It is best to take it 24 hours before entering the plateau.

If tourists choose to go to Tibet by plane, they should take as few articles as possible except sunglasses, cosmetics, medicines for colds and stomachs to avoid unnecessary physical exertion. All kinds of articles such as diet and clothing that tourists need can be bought in major supermarkets and department stores in Lhasa. At the same time, you should get enough sleep the night before sailing in low altitude areas, and don't eat greasy food or drink alcohol.

You must bring enough cash when you travel to Tibet. Because tourists can withdraw money from China Bank, China Agricultural Bank, China Construction Bank and China Postal Savings Bank in Lhasa, most other counties and towns generally cannot use credit cards.

Professionals suggest that if tourists choose to drive into Tibet from the Qinghai-Tibet line, the Sichuan-Tibet line, the Yunnan-Tibet line or the New Tibet line, then since most of these places are in extremely cold areas, even in summer, the temperature difference between morning and evening is large, so tourists must prepare cold-proof and rain-proof clothes and appliances. Because the catering and accommodation conditions in these sections are relatively simple, tourists may wish to bring some dry food and sleeping bags, and dry food and drinks should have enough calories, such as biscuits, chocolates and sweets. So that they can be prepared when there is a problem with the vehicle.

In order to minimize physical discomfort, tourists must observe the following items during their travels:

Drink more water. Because of the low air humidity at high altitude, human body is easy to dehydrate, and the increase of hemoglobin leads to the increase of blood viscosity, which is easy to form thrombus and cause cardiovascular and cerebrovascular accidents. Therefore, keep a small amount of water. Quit smoking or smoke less. Heavy smoking will obviously aggravate altitude sickness.

Exercise tests show that abdominal breathing is more regular and rhythmic than chest breathing. When walking or climbing, visitors can put their hands on their hips, so that the muscles of the arms, clavicle, scapula and trunk above the waist can assist breathing, so as to increase the activity of the respiratory system. When you first arrive at the plateau, you should avoid strenuous activities and emotional excitement, and avoid taking a hot bath, so as not to accelerate metabolism, aggravate hypoxia and lead to pulmonary edema. At the same time, adhere to the dietary principle of high sugar, high plant protein and low fat. Sugar can provide heat quickly, make people adapt to high-intensity activities and increase the exchange ventilation of oxygen. Too much fat and animal protein will aggravate altitude sickness.
