NEW YORK, Jan. 16 – New research has shown sleep less than six hours a night can increase the risk of cardiovascular disease, although too much sleep can also be detrimental to heart health can affect.
Carried In the new study, which was studied by Spanish and US researchers, 3,974 Spanish adults with no known heart disease were examined and participants were asked to wear an Actigraph for seven days ̵
were then divided into four groups: those who slept less than six hours, those who slept for six to seven hours, those who slept for seven to eight hours, and those who slept for more than eight hours.
Participants also completed a 3D heart ultrasound and cardiac CT scans looking for signs of heart disease.
The results published in the Journal of the American College of Cardiology showed that other possible ri were considered. For sk factors, participants who slept less than six hours had a 27 percent increase Probability of atherosclerosis, a plaque accumulation in the arteries of the body, compared to those who slept for seven to eight hours.
Participants with poor sleep quality, defined By how many times they woke during the night and how often they moved, the likelihood of atherosclerosis was 34 percent higher than in those who had good sleep quality.
"It is important that this shorter sleep duration is detected is of good quality to overcome the adverse effects of the shorter length," said co-author Valentin Fuster.
However, too long sleep also seemed to have a detrimental effect on health eight hours a night and an increase in atherosclerosis.
"Cardiovascular disease is a major global problem that we use by using different approaches, including pharmacology, to prevent and treat euticals, physical activity and nutrition. However, this study emphasizes that sleep must be included as one of the weapons we use to fight heart disease – a factor we endanger every day, "said senior study author José M. Ordovás." This is the first study This shows objectively measured sleep is independent of atherosclerosis throughout the body, not just in the heart.
Ordovás added that previous studies have shown that sleep deprivation increases the risk of cardiovascular disease by increasing risk factors for heart disease such as glucose levels, blood pressure, inflammation and obesity.
For those who want to improve their sleep, avoiding or limiting alcohol and caffeine can help, with researchers also finding that consuming both in participants with short and interrupted sleep was higher.  "Many people believe alcohol is a good sleep aid, but it does give a rebound effect," said Ordovás. "If you drink alcohol, you can wake up after a short sleep period and find it hard to fall asleep again. And when you fall asleep again, this is often a bad sleep. "
As for caffeine, he adds," Depending on genetics, the coffee can be metabolized faster, but it does not affect sleep. If you metabolize slowly, caffeine can affect your sleep and increase the likelihood of cardiovascular disease. "- AFP-Relaxnews
