Most and Sleep Deprivation Increase the Risk of Cardiovascular Disease

Suara.com – Sleep deprivation is often said to increase the risk of cardiovascular disease. But a study says it turns out most of the sleep can also pose the same risk.

Reporting from Science Daily, people who slept less than six hours increased their cardiovascular odds by 54 percent. While people who sleep more than eight hours will increase 39 percent cardiovascular risk.

This research is reported in American College of Cardiology.

“The message, based on our findings, getting too little sleep seems bad for your health, but too much also seems dangerous,” said Evangelos Oikonomou, MD, cardiologist consultant and lead author of the study.

“Unlike other heart disease risk factors such as age or genetics, sleep habits can be adjusted and even after considering the effects of risk factors established for atherosclerosis and cardiovascular disease.” he added.

The risk factors in question are age, sex, obesity, smoking, hypertension, diabetes, high blood pressure and even a history of coronary artery disease.

“Both short and long sleep duration can both act as additional risk factors,” said Oikonomou.

For this analysis, the researchers assessed sleep patterns in 1,752 people living in the Corinthia region of Greece using a standard questionnaire sent by trained cardiologists.

Participants were then divided into one of four groups based on reported sleep duration, including: normal group (seven to eight hours a night), short sleep duration (six to seven hours a night), very short sleep duration (less than six hours a night) and long sleep duration (more than eight hours a night).

Participants represented a broad spectrum of the general public, including healthy people as well as those with cardiovascular risk factors and heart disease. Their ages range from 40 to 98 years, with an average age of 64 years.

“We don’t fully understand the relationship between sleep and cardiovascular health. It could be that the withdrawal of the sympathetic nervous system or the slowdown that occurs during sleep can act as a recovery phase for blood vessel and heart tension,” Oikonomou said.

The researchers said that adopting a balanced sleep pattern of between six to eight hours every night might be exactly what the doctor ordered.

“It seems that this amount of sleep can act as an additional protective factor for the heart among people living in modern western society and there may be other health benefits to getting enough and quality sleep,” Oikonomou added.
