Why your heart needs a good night's sleep


MONDAY, January 14, 2019 (HealthDay News) – six hours: This is the minimum amount of sleep you need to help your heart stay healthy at night, according to new research.

The study found that chronic lack of sleep and poor sleep quality increases the chances of fat deposits in the arteries – a condition known as atherosclerosis, which increases the chances of a heart attack and stroke.

There are many ways to combat heart disease, including "pharmaceuticals, physical activity and nutrition", said lead investigator Jose Ordov. "But this study emphasizes that we need to include sleep as one of the weapons we use to combat heart disease – a factor that we endanger every day."

Ordov is a researcher at the National Center for Cardiovascular Research in Madrid, Spain.

In the new study, his team used a coronary ultrasound and CT scan to track the health of nearly 4,000 Spanish adult arteries. Participants in the study, on average 46 years, had no heart disease at the start of the study.

The study could not explain the causes and consequences, but people who lay less than six hours a night were 27% more likely to have atherosclerosis in the body than those who slept between seven and eight hours a night, Ordov and his colleagues reported.

Also too much sleep was not good for the heart. The study also found that women who slept more than eight hours at night had an increased risk of atherosclerosis.

Participants with "poor quality" sleep – often waking up or having difficulty sleeping – were also 34% more likely to have atherosclerosis compared to those of good quality.

The study was published American Cardiology College Magazine.

"This is the first study that shows that objectively measured sleep is independently associated with atherosclerosis throughout the body, not just in the heart," Ordov said in a news release. He also runs nutrition and genomics at the Jean Mayer USDA Center for Human Nutrition Research for the Elderly at Tufts University, Boston.

People with short and poor quality sleep conditions also used higher levels of caffeine and alcohol, Ordov said.

"Many people think alcohol is a good inducer of sleep, but there is a return effect," he said. "If you drink alcohol, you can wake up after a short sleep period, and it is difficult for you to return to sleep. And if you return to sleep, it is often a poor quality sleep."

Two US experts agreed that sleep is a key element of cardiovascular health.

Although the direct causal relationship between sleep and heart health remains unclear, "in the medical world, it is finally recognized that sleeping habits are recognized as an important factor in improving heart disease," said Dr. Eugenia Gianos. She leads the health of female heart at the Lenox Hill Hospital in New York.

Gianos argued that behavior in the waking hours of man can explain the sleep of the heart. This is because patients with good sleep hygiene have the energy to be physically active, choose healthy food choices and be able to work better, ”she said.

Dr. Thomas Kilkenny manages sleeping pills at Staten Island University Hospital, including New York. The new study "opens the door for further research, hopefully showing the cause and effect of poor sleep quality and the onset of atherosclerosis disease," he said.

"Meanwhile, doctors should constantly evaluate patients to determine sleep disorders and stress the need for patients to keep at least six to eight hours of sleep time," said Kilkenny.
