According to a new study, led by the team of scientists from Harvard Medical School and published in The Lancet, an impact of a constant stress on a deep-lying region of the brain explains the higher heart disease risk.
In the study, three hundred people participated, and those with higher activity in the amygdala were more likely to develop a cardiovascular disease. Also, the scientists highlight that these people were also to develop it sooner.
Dr Ahmed Tawakol, the lead author and associate professor of medicine at Harvard Medical School, said: “Our results provide a unique insight into how stress may lead to cardiovascular disease. This raises the possibility that reducing stress could produce benefits that extend beyond an improved sense of psychological wellbeing.”

A recent survey suggests that exercising just on weekends is enough to produce health benefits and prevent early death.
For their study, the researchers from Loughborough University and the University of Sydney analysed data of 64,000 people aged over 40 in England and Scotland. They examined the time people spent for exercise and their health over 18 years.
According to the findings of the study, people who did their exercise on one or two days of the week were found to cut their risk of dying from cardiovascular disease by 41% and cancer by 18%, compared to those who didn’t exercise at all.

According to a new research, calcium supplements may have a harmful effect on your heart. At the same time, foods rich in calcium do not have such properties. Authors of the study believe that their findings should give consumers time for thought.
For their study, the team of the researchers analyzed data from 10 years of medical tests on more than 2,700 adults in a heart disease study.
Dr. Erin Michos, a lead author of the study from Johns Hopkins University School of Medicine in Baltimore, says: “Our study adds to the body of evidence that excess calcium in the form of supplements may harm the heart and vascular system.”
