Hypertension is a very common disease, whereby the risk factors of its development has been well studied. However, researchers from England claim to have discovered a previously unknown factor is “geographic”.

British researchers report that they have discovered a previously unknown risk factor for the development of high blood pressure, which is associated with geographical latitude of the place of residence.

According to the staff clinic at the University of Birmingham (University Hospitals Birmingham), the risk of hypertension increases proportionally to the distance from the equator, though this statement applies only to the inhabitants of the southern hemisphere.

As the object of research for nearly 4 600 adults residents of the South American countries of Chile (Chile).

Your choice of the authors of the study explained that Chile is the only country in the world, whose territory stretches from North to South by as much as 4 of 250 km.

Analysis of data on the incidence of arterial hypertension among the study participants showed that it met 37% of the inhabitants of the southern regions of the country and only 29% of the inhabitants of the Northern regions closest to the equator.

The authors of this study are unable to identify the exact causes that they discovered the connection between latitude of residence and risk of developing hypertension, however, believe that it can be caused by more intense ultraviolet radiation near the equator.

Ultraviolet rays contribute to the production of vitamin D and nitric oxide NO – a deficiency of both nutrients leads to a higher risk of developing hypertension.

It is also possible that living in relatively close proximity to the equator can cause a more healthy lifestyle, in particular the inclusion in the diet of a large number of vegetables and fruits.

However, while it is also unclear whether the validity of laws discovered by scientists from Birmingham, and on the Northern hemisphere.
