Generally, for every 1000 meters increase in altitude, the temperature decreases by 6 ℃, so it is important to keep warm.

So, when moving in areas above the snow line, it is important to wear snow covered glasses or at least good sunglasses that can filter out ultraviolet rays. Snow blindness can cause temporary blindness, with mild symptoms including sensitivity to light, blinking continuously, sand like eyes, pain, redness, and constant tears. If snow blindness occurs, the eyes should be cleaned with eye drops and placed in a dark place or covered with an eye mask. The eyes should be chilled with a cold towel to reduce eye strain and rest as much as possible. Good rest and a soothing environment can promptly alleviate the symptoms of snow blindness, but complete recovery usually takes 5-7 days.

People unfit to travel to Lhasa
Patients with obvious lesions in the heart, lungs, brain, liver, and kidneys, as well as severe anemia or hypertension, should not blindly enter high altitudes. If you have never been to a plateau, it is recommended that you undergo a rigorous physical examination before entering the plateau.
Tourists with organic diseases, severe anemia, or severe hypertension have poor adaptability to high-altitude environments. They have a significantly higher risk of developing acute altitude sickness in the early stages of entering the plateau compared to others; If one stays at high altitude for too long, they are also more susceptible to various chronic altitude diseases than others. Meanwhile, as the body needs to adapt to the high-altitude environment, the compensatory activities of important organs such as the liver, lungs, heart, and kidneys are enhanced, which increases the burden on these organs. Once these cavities develop a disease, it will further worsen the condition.
