You can invite friends and family to play together, but the altitude of Tibet is over 4,000, so be careful not to get too high.
Cause
Decreased partial pressure of oxygen: Lhasa has a high altitude, and the atmospheric pressure decreases with increasing altitude. The partial pressure of oxygen in the air also decreases, resulting in insufficient oxygen inhalation by the human body to meet normal physiological needs.
Insufficient body adaptation mechanism: After arriving in Lhasa quickly from a low-altitude area, the body’s physiological regulation mechanisms such as breathing and circulation cannot adapt to the low-oxygen environment in a short period of time, thus triggering symptoms of altitude sickness.
Individual differences: Different people have different tolerances to hypoxia. People with weak cardiopulmonary function, poor hemoglobin oxygen-carrying capacity, or underlying diseases are more likely to suffer from altitude sickness.
Excessive activity: Performing strenuous exercise or overexertion when you first arrive in Lhasa will increase the body’s oxygen consumption, aggravate hypoxia, and make altitude sickness more obvious.
Common symptoms
Mild altitude sickness: mild headache but does not affect daily activities and thinking; slightly short of breath but can still talk and move normally; mild dizziness but can maintain balance and walk; fatigue but can complete basic movements; slight decrease in appetite
Severe altitude sickness: Severe headache, unbearable, affecting thinking and movement, accompanied by nausea and vomiting; difficulty breathing, obvious shortness of breath or even wheezing; severe dizziness, inability to maintain balance, difficulty walking; palpitation, abnormal fast or irregular heartbeat, chest Discomfort; confusion, confusion, slow reaction; extreme weakness, inability to stand or perform simple activities; cyanosis of lips or nails
Coping methods
Prepare in advance: Under the guidance of a doctor, you can prepare medicines to prevent and alleviate altitude sickness before departure, such as rhodiola rosea, etc., and start taking them one to two weeks in advance; maintain a good attitude and avoid stress and anxiety. Excessive mental stress may aggravate the symptoms of altitude sickness.
Measures upon arrival: Move slowly and avoid strenuous exercise and rushing; go to your scheduled accommodation to rest as soon as possible to allow your body to adapt to the plateau environment; drink plenty of water to keep your body well hydrated; eat light and avoid greasy, spicy and irritating foods, and eat more Eat easily digestible food; keep warm; the temperature difference between day and night in Lhasa is large, so you should add or remove clothing in time; if the symptoms of altitude sickness are severe, you can take appropriate oxygen to relieve the symptoms, but you should not rely too much to avoid affecting the body’s ability to adapt
Things to note
If you have early symptoms of a cold or factors that make you susceptible to colds, you should pay attention to distinguish whether it is a cold or altitude sickness after arriving in Lhasa, because a cold may aggravate the symptoms of altitude sickness. If it is difficult to judge or the symptoms are severe, you should seek medical treatment in time.

People who live in Lhasa for a long time also need to exercise moderately, eat a balanced diet, drink plenty of water, get enough rest, avoid colds, and have regular physical examinations to maintain good physical condition and cope with possible altitude sickness.
