Here are a leading cause of lung cancer. You will not believe it!
While so far all scientific studies that sought to establish a link between lung cancer and the air we breathe have investigated its composition, a recent study came to bring a new dimension to this question: the altitude !
In fact, that study found that people living in towns and villages at a level close to that of the sea would be more likely to contract lung cancer than those living at altitude.
The reason for this phenomenon? Incredible as it may seem, the highest prevalence of lowlanders to see their lungs affected by cancer is due to oxygen. The air in the plains is actually thicker than the heights as more responsible in oxygen, which turns out to be hazardous to the human body.
This is because oxygen is used by the body to convert food into energy and that during this process, known as oxidation, many free radicals can be produced. But these chemicals, which have the ability to cause reactions in cell killing chain, and even modify the genetic code of the cells by attacking their DNA, can go up to cause a mutation of the genetic program of the human body. In doing so, free radicals are responsible for the development of cancer.
So to summarize, the more air is loaded with oxygen, the more it will release free radicals during oxidation and risk of developing lung cancer, first organ affected by oxidation. Conversely, a low oxygen means less oxidation and less risk of cancer associated with free radicals. This would be verified, according to a US study from 1000 meters above the level of the sea.
It is time to start wearing extreme attention to the air around you. And to reduce the risk of cancer while taking a breath of fresh air, more hesitation for the next holiday, heading toward the hills to breathe deeply!
