Slowing Down Aging: Two Factors Identified by Scientists

The results of a study conducted by American scientists from the Massachusetts Hospital in Boston showed that hypoxia prolongs life by 50%.

This happens by slowing down aging or reducing the rate of its decisions and development. The results of the study were published in the journal PLOS Biology.

In the experiments, lab rats breathed air containing 11 percent less oxygen than usual, which is equivalent to living high in the mountains and, for example, in the base camp on Mount Everest at an altitude of about 5000 meters above sea level.

It is reported that scientists have not yet discovered the mechanisms for slowing down aging. But they only suggest that a chronic lack of oxygen somehow triggers processes in the cells, thanks to which the cells begin to compensate for the damage that inevitably manifests itself over the years.

This is at a time when scientists at the University of Michigan in the US discovered another path to active and healthy longevity and explained where that path begins in the journal Science.

According to one of the authors of the study, university physiologist Scott Pletcher, fasting has such an effect. It is not the reduction in calories that is surprising, but the constant feeling of insatiable hunger, rejuvenating youth and positively affecting the body as a whole. Or, in other words, you can eat enough, but from time to time you experience an acute need for food.

In experiments on flies, the researchers did not limit themselves to food, but simulated the feeling of hunger by stimulating the corresponding neurons in the brain. Flies that were starving lived longer and were less likely to get sick.

According to Michigan scientists, “hungry neurons” produce modified helper proteins, called histones, that bind to DNA and help regulate gene activity. Moreover, previous studies have shown that the higher the number of histones, the longer the lifespan.

But there is a big question, to what extent the results of experiments carried out on mice and flies can be transferred to the human body?
