Study: Sleeping For 7 Hours to Keep Your Heart Younger

Sleep duration coupled with excess heart age may prove helpful for communicating the cardiovascular risks and benefits associated with sleep duration

Sleeping for seven hours a day may reduce the age of your heart as well as decrease the risks for cardiovascular disease, say researchers.

The study showed that excess heart age is the lowest in adults who sleep seven hours a night.

Sleeping times less than or greater than seven hours were associated with increased excess heart age, while short sleepers had the highest elevations in excess heart age.

Sleep duration coupled with excess heart age may prove helpful for communicating the cardiovascular risks and benefits associated with sleep duration.

“These results are important because they demonstrate a quantitative method for the inclusion of sleep duration in the establishment and communication of cardiovascular risk for individuals,” said Julia Durmer from the Emory University in Georgia, US.

The study, published in the journal Sleep, included data from 12,775 adults aged between 30-74 years.

They self reported their sleep duration which was classified into five categories — five hours or less, six, seven, eight, nine and/or more hours of sleep.

The team used sex-specific Framingham heart age algorithm to calculate each individual’s heart age and used multivariable linear or logistic regression to examine the association between sleep duration and excess heart age.

The results showed that mean adjusted excess heart age was lowest among adults who reported sleeping seven hours per 24-hour period.

“This could have utility in the clinical care of patients with cardiovascular risk, and for public health researchers interested in adding a sleep metric to future studies,” Durmer said.

According to the US-based National Sleep Foundation, people who do not sleep enough are at higher risk for cardiovascular disease and coronary heart disease-regardless of age, weight, smoking and exercise habits.

Sleeping too little causes disruptions in underlying health conditions and biological processes like glucose metabolism, blood pressure and inflammation. However, the same may hold true for over sleeping. (IANS)

Drinking Even 25 Cups of Coffee in a Day Not Bad for Heart, Says Study

The study was presented at the British Cardiovascular Society (BCS) conference in the UK

There is good news for those who like their cup of coffee every morning. Drinking coffee, even up to 25 cups a day, is not as bad for arteries and heart as previously thought, says a study.

The researchers found that drinking coffee was not associated with stiffer arteries as previously thought.

Arteries carry blood containing oxygen and nutrients from heart to rest of the body. If they become stiff, it increases heart’s workload and raises the chance of heart attack or stroke

“Despite the popularity of coffee worldwide, different reports could put people off from enjoying it. While we can’t prove a causal link in this study, our research indicates coffee isn’t as bad for arteries as previous studies would suggest,” said Kenneth Fung, who led the data analysis for the research at the Queen Mary University of London.

For the study, involving 8,000 people in Britain, coffee consumption was categorised into three groups. Those who drink less than one cup a day, those who drink between one and three cups and those who drink more than three.

“Coffee is one of the most popular beverages and a lot is known about its physical effects,” said Sam Maglio, Associate Professor at the University of Toronto in Canada. Pixabay

No increased stiffening of arteries was associated with those who drank up to this high limit when compared with those who drank less than one cup a day, said the researchers.

“Although the study included individuals who drink up to 25 cups a day, the average intake among the highest coffee consumption group was five cups a day. We would like to study these people more closely in our future work to help advise safe limits,” Fung said.

“This research will hopefully put some of the media reports in perspective, as it rules out one of the potential detrimental effects of coffee on our arteries,” said Metin Avkiran from British Heart Foundation.
