My parents are old and want to take them to Xining for a few months and then go back to the plain. Xining is 2300 meters above sea level. Is it harmful to the health of the elderly?

First, you should assess the age of your parents. There is generally nothing wrong with people under 60. If they are over 60, you should look at their physical health. If you have suggestions on hypertension, heart disease and lung disease, you'd better not do it.

Secondly, when your parents go to Xining, I personally suggest that June to September is the best in the Gregorian calendar every year. The temperature and humidity at this time are the most comfortable time in Xining. The rest of the time depends on your parents' health.

The third option is transportation. Personally suggest the train. Of course, the sleeper is the best. After all, you can give the elderly some time to adapt.

Fourth, prepare some medicinal materials to prevent altitude sickness, such as rhodiola, in case of emergency.
