Research reveals how sleeping cycle may increase heart attack risk

New research published in the Journal of the American College of Cardiology reveals that to live a healthy life it is necessary to maintain heart health and this could be done by getting the right amount of sleep of about 6 to 9 hours every night.

The sleep habits, genetic factors and medical records of about 461,347 people between the ages of 40 to 69 years, analyzed by the researchers of U.S and U.K.

Sleep Duration is a key to Heart health

According to this study, the analysis has some shocking outcome. It tells that the people with sleep less than 6 hours per night were at 20% risk of a heart attack. On the other hand, people having the sleep of 6-9 hours per night were at less risk of a heart attack. But the people who oversleep are at a higher risk of 34%.

In addition to this, in people, having a heart attack as a genetic disease, getting the right amount of sleep can reduce the risk of first heart attack by 18%. So, this study proved that having too little or too much sleep can ultimately lead to stroke hence can even prove fatal.

“This provides some of the strongest proof yet that sleep duration is a key factor when it comes to heart health and this holds true for everyone,” says Vetter, who is an assistant professor at the University of Colorado at Boulder.

Relationship between the Duration of Sleep and Death:

According to the Journal of the American Heart Association, researchers from Keele University in the U.K, the study revealed a “J-shaped” relationship between sleep duration and death. It implies that the amount of risk in line rose with a greater amount of sleep, for example, 9 hours of sleep lead to the 14% risk of death. On the other hand, sleeping more than 10 hours may lead to a 30% higher risk.

According to the authors, this finding came to the result that sleeping more than 7 to 8 hours per night “may be associated with a moderate degree of harm”.

Dr. Chun Shing Kwok, a lecturer at the University of Keele and also the lead researcher says, “Our study has an important public health impact in that it shows that excessive sleep is a marker of elevated cardiovascular risk.”

To conclude, sleeping too much or having the amount of sleep less than normal, both situations are problematic. If you are sleeping too much, it could be a sign of any of the chronic diseases like diabetes, heart disease or depression.

In this case, consulting your doctor is the only way to prevent yourself from big harm. On the other hand, if you are not having the sleep of about 6 hours then it makes you feel tired throughout the day. It also suppresses your mental abilities, creativity or productivity. Moreover, Mendelian randomization also showed that short sleep durations influenced by genetic factors have a higher risk of a heart attack.
