Can people in poor health go to Tibet?

In addition to maintaining a good attitude, there is no special requirement for a healthy body when entering Tibet. People with severe respiratory, tracheal, cardiac, cardiovascular and mental diseases are not allowed to enter Tibet. Therefore, patients with severe hypertension, heart disease, bronchitis, diabetes and colds are restricted from entering Tibet. Generally, you don't need a physical examination to go to Tibet, and people who don't have the above serious diseases can also go to Tibet. It is suggested not to exercise deliberately before entering Tibet, because after exercise, the oxygen consumption increases, which increases the burden of entering the heart of Tibet, but it is easy to cause altitude sickness.
