Although previous research has established a link between sleep health and heart disease, a new study in the journal Scientific Reports says that having multiple sleep problems can increase middle-aged adults’ risk of developing heart disease.
Researchers at the University of South Florida looked at data from 6,820 adults, with an average age of 53 years old, who had self-reported their heart health and the regularity, quality, efficiency, and length of their sleep. Of those participants, 663 also wore sleep monitors to track their sleep timing.
Individuals who self-reported multiple co-existing sleep issues had a 54% higher risk of heart disease, according to the research. Among participants who wore a sleep tracker, that risk increased to 141%.
Heart disease remains the leading cause of death in the United States, and researchers say that understanding co-existing sleep issues can motivate individuals to protect themselves from it.
Reported sleep issues included:
Results showed differences between men and women’s sleep patterns and heart health issues. Women reported more sleep problems, while men reported more heart issues, for example. Sex did not affect the overall link between poor sleep and increased heart disease risk.
Findings also showed that although there were racial differences within sleep and heart health, race did not affect the link between multiple sleep issues and risk of heart disease.
Researchers also note that poor sleep health in middle-aged adults may lead to the loss of productivity, impaired immune functioning, other illnesses in later life, and early death.
Individuals can help reduce their heart disease risk by improving their sleep with good sleep hygiene. Elements of sleep hygiene include maintaining consistent sleep schedules, getting the recommended amount of sleep, and creating a sleep-friendly bedroom.
Middle-aged adults with multiple sleep issues, such as irregular sleep schedules while also often sleeping less than six hours per night, can improve their sleep health to help prevent future heart disease, researchers say.
