A major new study published in the American Heart Association’s journal Circulation shows that middle-aged women who sleep less than five hours a night have a dramatically increased risk of cardiovascular disease.
Researchers at the University of Pittsburgh followed nearly 3,000 women between the ages of 42 and 52 for 22 years, recording their sleep habits and heart health.
The majority of women (55%) said they slept about 6 hours and 30 minutes each night, but 14% reported regularly sleeping less than 5 hours.
The study found that women who averaged less than five hours of sleep each night were 72% more likely to have a stroke, heart attack, heart failure, and coronary artery disease than those who slept six or more hours each night. .
The health effects were even worse for women who suffered from insomnia symptoms three or more times a week and slept less than five hours on average.
These women were found to be 75% more likely to develop heart disease.
Experts suggested there may be a link between sleep and heart disease, as insufficient sleep can increase blood pressure and cause insulin resistance, which increases the risk of blood vessel damage.
Lack of proper sleep also increases a woman’s risk of obesity, which contributes to cardiovascular problems.
The researchers suggested that this was likely due to the tired body’s inability to monitor hunger and satiety.
Previous research has shown that many adults suffer from increased sleep problems and worsening cardiovascular health as they reach middle age.
The Centers for Disease Control and Prevention recommends that adults get at least seven hours of sleep a night, but younger people need more than the recommended average amount of sleep to stay well-adjusted. Despite being aware that they need more sleep, many Americans seem to have a hard time achieving this important goal. function.
Lack of deep sleep can also negatively impact your physical and mental health.
Heart disease is the leading cause of death in women, with approximately 1 in 5 deaths among women in 2021 due to heart disease, the CDC reported.
