[메디컬투데이=한지혁 기자] The cardiovascular risk of insomnia patients was found to be significantly higher than that of normal people.
The results of a study investigating the impact of insomnia on the risk of cardiovascular disease were published in the academic journal ‘PLoS One’.
Insomnia refers to a condition in which it is difficult to fall asleep or maintain sleep throughout the night. According to the U.S. National Library of Medicine (NLM), approximately 30% of adults worldwide experience insomnia.
Statistically, insomnia patients are exposed to the risk of various diseases such as diabetes, kidney disease, and gastrointestinal disease. Several previous studies have addressed the link between insomnia and cardiovascular disease, but these series of studies have produced mixed results.
Accordingly, a research team conducted a meta-analysis of previously published research data to determine whether an unknown link exists between insomnia and cardiovascular disease.
The analysis included data from 21 studies published over the past 20 years, totaling 389,000 insomnia patients and more than 2 million healthy participants. All participants were adults over 18 years of age, and the average ages of the insomnia and normal participant groups were 59.4 and 58.6 years, respectively.
As a result of the analysis, various diseases, including cardiovascular disease, were associated with insomnia. The risk of cardiovascular death in the insomnia group was 53% higher than that of the normal control group, and the incidence rate was also 31% higher.
When only study data that followed participants for more than 10 years were included in the analysis, the difference in mortality rates between the two groups was much higher. This means that insomnia causes not only short-term symptoms but also long-term significant problems.
The researchers speculated that various changes occurring in the body due to insomnia, such as changes in autonomic nervous system activity and increased levels of systemic inflammation, may have had a complex effect on cardiovascular health.
They noted that maintaining sleep hygiene and improving overall sleep quality are very important factors in maintaining health, and suggested healthy sleep habits such as exercising regularly during the day and avoiding naps.
