Can sub-health go to Tibet?

Usually people with high blood pressure are not allowed to enter Tibet, but your father's blood pressure is not too high and relatively stable. You can enter Lhasa first, adjust there and then decide whether to go elsewhere.

First, don't exercise. The more your vital capacity increases, the greater the altitude sickness. Generally speaking, people who have no obvious altitude sickness are sub-healthy and sickly. Hehe, what your father needs to do now is to take antihypertensive drugs every day to keep his blood pressure in a balanced range.

Secondly, going up by train and slowly adapting to the rising altitude is very beneficial to the adjustment of the body. If you fly to Lhasa and pull more than 3000 meters at a time, a strong young man may not be able to bear it.

Third, after arriving in Lhasa, buy oxygen bottles and a medicine called Gao Yuan 'an to get ready.

Finally, take medicine.
