I am in Lhasa, Tibet! Although this requires drinking more water! But I drink more than the people around me! Three or four liters a day! I am a boy. Is this harmful to my health?

You're right. You really need to drink more water in Tibet, especially in Lhasa. But your daily intake of 3-4 liters is a bit high, which will affect your health. Because drinking plenty of water will increase the burden on the kidneys. It is recommended to drink about 2 liters of water every day and wear lipstick. If you are used to it, you can try butter tea. It makes sense to drink butter tea in Tibet. It can not only supplement water and salt, but also contain oil, which can protect lips and prevent chapped lips.
