How does biology explain this? Scenario 1 – Talking of the Tibetans, their body is accustomed to a scenario known as vasodilation where the blood vessels get dilated to provide for less oxygen in the body. Further, this process improves the blood supply and reduces blood pressure for enough oxygen to be there in the arteries. These characteristics in their bodies help with keeping away from hypertension. Additionally, one of the studies says, a person is at risk of suffering from hypertension when the process of vasodilation gets disturbed. The arteries get thick and this even disturbs the blood flow. Scenario 2 – The Tibetans are used to another process known as blunted red blood cell production to be able to reduce the risk of suffering a chronic disease.
How? Generally, when your the body feels hypoxic stress, the kidney gets a signal to enable excessive red blood cells to provide enough oxygen to all the tissues and thickens the blood. WWW.HEALTHSPECTRA.COM | MAY 2020
In this case, people suffering from diabetes are at a risk given that their kidneys don’t function well and they are sensitive to hypoxia. This prevents the body from correcting anemia(fewer blood cells). Having said, the way Mosuos body functions are different and they get to save themselves from this complication. According to one of the studies in the past, the Mosuo communities are working on their diet, physical activity, and social structure to be able to keep up with this health condition to be able to do well when tourism takes place. In addition to this, it was even found that their amount of physical activity had reduced and a change in their diets like including sweet beverages and processed foods could have been the reason for people suffering from chronic diseases such as diabetes and hypertension. For the most part, when compared to hypertension and diabetes in chronic diseases, the cases of diabetes are more and they thought of researching over the high-altitude adaptation the second time to see if the risk of suffering from a chronic disease was less.
Scenario 3 – Collaborating
the information from Yunnan province, a small group from rural Hunan and China Health and Nutrition Survey for the Han comparison groups, they tried to check if there is a link between adaptations and the chronic disease. Han is a little lower in altitude. Therefore, the researchers compared the risk of Hypertension in Mosuo and Han in terms of their diet. 62
