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)

Rose Scent Can Improve Learning and Sleeping Quality: Study

Scent of rose improves learning and sleeping

Researchers have found that smelling the scent of rose improves the quality of the learning and can also helps in sleeping better.

The study, published in the journal Scientific Reports, was conducted within pupils of two classes that learned English vocabulary, one of which learned it with the scent sticks while the other one did it without it.

“We showed that the supportive effect of fragrance works very reliably in everyday life and can be used in a targeted way,” said study leader Jurgen Kornmeier from the University of Freiburg in Germany.

For the study, first author and student teacher Franziska Neumann conducted several experiments with 54 students from two 6th grade classes of a school in southern Germany.

The young participants from the test group were asked to place rose-scented incense sticks on their desks at home while learning English vocabulary and on the bedside table next to the bed at night.

In another experiment, they also placed the incense sticks on the table next to them during a vocabulary test at school during an English test.

The results were compared with test results in which no incense sticks were used during one or more phases.

“The students showed a significant increase in learning success by about 30 per cent if the incense sticks were used during both the learning and sleeping phases,” Neumann said.

The results also suggest that the additional use of the incense sticks during the vocabulary test promotes memory.

“One particular finding beyond the seminal initial study was, that the fragrance also works when it is present all night, this makes the findings suitable for everyday use,” Kornmeier said.

“Our study shows that we can make learning during sleep easier. And who would have thought that our nose could help considerably in this,” Kornmeier said. (IANS)
