A recent study provided in the European Journal of Preventive Cardiology informs the world that chronic sleep problems significantly increase the risk of developing cardiac and blood vessel pathologies.
First of all, we are talking about "vascular catastrophes" that threaten human life - about stroke and necrosis of the heart muscle (infarction). An interesting work on the study of this issue engaged researcher Chao He (Qiao He) from China, who is an employee at the Chinese Medical University. Undoubtedly, in her experiments, the scientist relied on the results of earlier observations:
- A high-grade dream is an incredibly important component of vital activity for the restoration of lost forces for the day, and also for the ordering of the information received.
- Every year the modern society increases the rate of suffering from insomnia.
- The absence of healthy sleep adversely affects the organs and systems of man.
Together with her research team, the scientist tried to expand her knowledge in this field and try to relate insomnia and risks to the heart and blood vessels. She analyzed 15 long-lasting (from 3 to 30 years) cases of experiments, attended by more than 160,000 volunteers. The participants suffered to some extent from the manifestations of insomnia: excessively slow falling asleep, frequent night awakenings, an early rise in the morning, a feeling that although asleep, but not at all rested. In the course of the analysis, 11,702 people were identified with complications from sleepless nights, including those from the heart.
With each of these variants of insomnia, volunteers had associated cardiovascular and brain manifestations (the exception was early morning recovery). Risks in those people who often could not sleep peacefully and quickly, were higher by 27% of risks in the absence of pathology of sleep. And if the subjects noted disorders of sleep itself or ordinary sleep, then it was possible to calculate the risks by 11% and 18% above the norm in each case.
Even in the absence of detecting a particularly significant percentage difference, researchers argue that the lack of sleep in their lives has a female gender. Women were the most susceptible to the effects of insomnia, but the harm from it, however, did not exceed that of men. Most likely this is interrelated with the effect of female sex hormones and a greater susceptibility of women to stress factors.
Chao Xie called to pay special attention to the "female" insomnia. Scientists from the University of Georgia were already studying it closely. The conclusions of their experiment were expected: women who raise children are more often affected by insomnia than the male half of the population.
While the researchers were not able to accurately determine what specifically causes such a harmful effect of sleep disorders on the cardiovascular system. Earlier, it was said about the violation of metabolic (metabolic) processes, the development of abnormal amounts of hormones, the activation of the sympathetic nervous system, and the increase in the level of arterial pressure. Chao Hyo herself as a leading expert of the scientific experiment called first of all to pay attention to herself, and also to inform patients about possible risks of the course of their disease.
