Snore at night There may be multiple reasons, but there is one in particular that would not only be dangerous in itself, but could even increase the risk of death from cancer.
To be specific, the reason for snoring at night that we will talk about today is the dreaded sleep apnea, a type of snoring pathological that affects millions of people around the world, more men than women, and that certainly causes great discomfort both for those who suffer it and their bed partners.
The study, recently presented in the Congress of the European Association of Urology, has concluded that snoring at night and come to suffer just from sleep could increase the risk of death from cancer.
The relationship between sleep apnea and the risk of death from cancer
The explanation for this relationship would have a side effect of this snoring known as sleep apnea: hypoxia, a condition where the body encounters an adequate decrease in oxygen. In sleep apnea what happens is that snoring is associated with episodes of apnea or shortness of breath. When these episodes are repeated too much each night (from 5 or more) we can diagnose the disease.
In this recent animal study, carried out by Dr. Antoni Vilaseca and colleagues from the Clinical Hospital of Barcelona24 mice with kidney cancer were divided into two groups (12 experimental and 12 controls). After subjecting them to various levels of hypoxia or lack of oxygen intermittently, imitating sleep apnea, it was detected that in their respective tumors there was a greater number of tumor cells of various types, many of which are essential for tumor development, nutrition, and expansion. In addition, they also detected a greater amount of a protein associated with many tumors: Vascular Endoterial Growth Factor or VEGF.
Sleep apnea feeds cancer in animals
Basically, and in a nutshell, sleep apnea will cause these episodes of oxygen starvation or hypoxia, and this in turn will increase cancer access to nutrients. thanks to the increase in blood vessels necessary to access them. That yes, it seems that the tumor size is not affected. At least, in animals, as Dr. Vilaseca well emphasizes:
This of course is an early study in animals, so we must be careful when applying the findings in humans. However, our work indicates that a mechanism where conditions of lack of oxygen flow to tissues, such as sleep apnea, can promote cancer is plausible.
The other diseases that are related to sleep apnea
But the sleep apnea It is not only here, and it is that several previous studies have come to relate this pathological snoring with other factors as diverse as memory loss or diabetes. Even some works indicate that sleep apnea may be an early sign of heart disease.
On the other hand, it seems that men snore more than women in general, so they are also more likely to experience particular sleep apnea. Let us be clear, that s, that snoring does not imply suffering from sleep apnea always, since there are many types of snoring. This particular one is one of the worst, as many other non-flattering factors have been associated with it.
