Sleeping too much or too little could increase risk of heart attack

Either way, sleeping too much or too little could give the scare of your life: heart attack risk. It does not matter if you go to the gym regularly or a non-smoker. The amount of sleep you get matters.

A new study published in Journal of the American College of Cardiology said the amount of sleep you have each day could increase your chance of having a heart attack.



461,000 Samples

The researchers analyzed a set of data collected from 461,000 individuals whose age bracket is between 40 to 69 years old. The sample population had no history of heart disease.

Based on the seven-year data, the researchers found out that people who slept no more than six hours every night are likely to have a heart attack by 20 percent. The rate is lower for those who slept 6 to 9 hours.

The findings, however, are no longer surprising nowadays. In fact, several studies had already linked sleep deprivation to depression, obesity, diabetes, anxiety, and heart disease.

Surprising

The result of this study is surprising in a sense that it says sleeping beyond nine hours could also increase heart attack risk by 34 percent. This rate is even higher than those who slept below six hours.

Also, the findings are shocking knowing that at least 30 other factors were considered. These factors include mental health, physical activity, and socioeconomic status. It was established by the study that sleep duration alone is a driver for heart attack risk.



Causal Relationship

There is clearly a relationship between sleep duration and heart attack risk, study co-author Celine Vetter, an assistant professor of Physiology at the University of Colorado Boulder, said.

But it is not yet established why sleep duration plays a big role in heart attack risk. One explanation suggests that sleep deprivation affects arteries and bone marrow. Too much sleep, on the other hand, may cause inflammation. (Roger Bridge for Mindanao Sun/ Featured Image: Pixabay)
