ISLAMABAD, March 28 (ONLINE): A new study reports, for the first time, the effect of poor sleep on the longevity of a person\u2019s cardiovascular health.<\/p>\n
Researchers from the University of Sydney in Australia and the University of Southern Denmark analyzed the sleeping experiences and cardiovascular medical histories of 308,683 middle-aged adults.<\/p>\n
The study found that sleep disorders are associated with a significant reduction in the number of years of cardiac, or heart, health a person experiences.<\/p>\n
Included in the study were clinical sleep disorders such as insomnia and breathing-related disorders, as well as a range of other sleep-related issues, such as schedule\/ chronotypeTrusted Source (sleep type) conflicts, snoring, and daytime sleepiness.<\/p>\n
The two most common breathing-related sleep disorders considered in the study were central sleep apnea and obstructive sleep apnea.<\/p>\n
The analysis revealed that breathing-related sleep disorders were linked to a shortening of a person\u2019s heart-healthy lifespan by around 7 years.
\nWhat the study found<\/p>\n
For women, breathing-related sleep disorders were associated with a 7.32-year reduction in heart-healthy years, and 6.73 years for men. People who slept poorly, according to the study\u2019s definition, saw an average 2-year reduction in cardiac health.<\/p>\n
The study explores the many types of sleep problems and their effect on heart health.<\/p>\n
\u201cSleep is multidimensional and complex,\u201d study co-author Prof. Emmanuel Stamatakis told Medical News Today.<\/p>\n
\u201cOur study suggests that it needs to be addressed holistically, and not to limit the discussion to, e.g., sleep duration only,\u201d he noted.<\/p>\n
The study\u2019s authors hope it encourages cardiologists and other doctors to bring up the topic of sleep with patients, and work with them to resolve issues that may affect heart health in the long term.<\/p>\n
The daily impact of poor sleep
\nBeyond its long-term health effects, poor sleep can impact people\u2019s daily lives in many ways.<\/p>\n
Being overtired increases the risk of accidents due to slower reaction times and lapses of attention, noted Dr. Jonathan Cedernaes, a sleep specialist from Uppsala University in Sweden, who was not involved in the study.<\/p>\n
In addition, it may degrade a person\u2019s daily physical performance, impair metabolic function, and promote inflammation, he added. Bad moods, irritability, and an inability to concentrate are all hallmarks of not getting enough sleep.<\/p>\n
\u201dWe all suffer from poor sleep from time to time, but it\u2019s when it becomes chronic that it may become an issue to worry about \u2014 that is when one should consider seeking professional help from healthcare providers,\u201d said Dr. Cedernaes.<\/p>\n
Poor sleep and long-term health
\nProf. Stamatakis suggested that the especially negative association between breathing-related sleep disorders and cardiac health may have to do with common issues underlying both.<\/p>\n
\u201cBreathing-related sleep disorders are caused to a large extent by established cardiovascular risk factors such as obesity and physical inactivity,\u201d he pointed out.<\/p>\n
Sleep-disordered breathing can also worsen sleep all by itself, resulting in more fragmented, and thus less restorative, sleep, noted Dr. Cedernaes.<\/p>\n
He added that poor sleep has also been linked to abnormal regulation of the cardiovascular system, including the heart and blood vessels, as well as increased inflammation, blood pressure dysregulation, and a disruption of the sympathetic nervous system.<\/p>\n
What the study did
\nIn the current study, the participants\u2019 sleeping histories were either self-reported or submitted by clinicians. The two types of data were analyzed separately.<\/p>\n
In research, there are always concerns about the accuracy of self-reported data. In this case, people may, for example, be asked to assess snoring they themselves do not hear. Prof. Stamatakis said that, nonetheless, self-reported sleep data generally capture the related health risks fairly well.<\/p>\n
However, he cautioned that \u201c[b]ecause of compromised accuracy, they [doctors] are bound to underestimate the true health consequences of poor sleep.\u201d<\/p>\n
Clinically observed breathing-related disorders reported by general practitioners or hospital doctors are less susceptible to measurement errors.<\/p>\n","protected":false},"excerpt":{"rendered":"
