Poor sleep increases the risk of heart attacks. A recent study suggests that 6 hours is the minimum amount of night sleep that contributes to the preservation of heart health.
The study found that chronic sleep deprivation and poor sleep quality increases the accumulation of fatty plaques on the artery walls – a condition known as atherosclerosis. It increases the risk of heart attacks and strokes.
Lead author Jose Ordovas (Jose Ordovas) notes that there are many ways to prevent cardiovascular diseases, including “drugs, physical activity and diet.” “But our research emphasizes that we should consider sleep as one of the measures to prevent heart disease, and we underestimate it every day.”
Ordovas is a researcher at the National Center for Cardiovascular Research (National Center for Cardiovascular Research) in Madrid (Spain).
In their study, a team of scientists using ultrasound and scans obtained by computed tomography, monitored the condition of the arteries of approximately 4,000 adult Spaniards. The average age of study participants was 46 years old, and at the time they began work, they did not have a cardiac pathology.
Ordovas and his colleagues reported that, although the study could not prove the cause and effect, people who slept at night for less than 6 hours had a 27% higher chance of developing atherosclerosis in the whole body compared with those participants who spent sleep at night 7 -8 ocloc’k.
However, excess sleep in the heart is also harmful. The study noted that women who slept at night for more than 8 hours had an increased risk of developing atherosclerosis.
Participants in the study who had poor sleep quality – frequent waking ups, difficulty falling asleep – also had an increased risk of developing atherosclerosis (34% more than people who do not have similar sleep problems).
The work was published on January 14 in the Journal of the American College of Cardiology.
“This is the first study in which it is shown that objectively measured sleep is independently associated with atherosclerosis not only of the heart, but of the whole organism,” Ordovas said in a press release of the magazine. He is also the head of the Nutrition and Genomics Department at the Jean Mayer USDA Human Nutrition Research Center on Aging, which is located in Boston at Tufts University, of the Gene Mayer Research Center on Human Nutrition and its Aging.
Ordovas reported that people who slept little or had poor sleep quality tended to consume higher doses of caffeine and alcohol.
“Many people believe that alcohol is a good means for falling asleep, but in fact it has the opposite effect,” says the scientist. “After drinking alcohol, a short sleep period is replaced by awakening and subsequent difficulties in falling asleep.” And if a person falls asleep again, then often this dream has a bad quality. ”
Two American experts agreed that sleep is a key component of cardiovascular health.
Although the direct causal relationship between sleep and heart health remains unclear, “focusing on sleep habits is finally becoming recognized in the medical world as an important factor for improving heart health,” says Dr. Eugenia Gianos. She directs the Department of Cardiac Pathology in Women at Lenox Hill Hospital in New York.
Janos believes that the behavior in a person’s wakefulness hours can explain the connection between sleep and heart health. She notes that patients with good sleep quality have more energy to be physically active, choose healthy foods and better cope with stress.
Dr. Thomas Kilkenny (Thomas Kilkenny) leads the sleep study department at Staten Island University University Hospital in New York. According to him, the new study “opens the door to further scientific research in order to identify the causes and effects between poor sleep quality and the development of atherosclerosis.”
“Meanwhile, physicians should constantly evaluate the quality of sleep of patients and emphasize the need for 6-8 hours of sleep for them,” Kilkenny said.Related Articles :
