There is much great research going on in mainstream science and at least some of it related to mindfulness, and sometimes written about in mainstream media such as in this TIME article:
"... Even at the cellular level, stress seems to affect health; chronic stress has also been shown to harm DNA by shortening telomeres, the protective caps on the ends of chromosomes.
This is not the first time research has suggested that how we feel about aging can affect how we age. Other research has shown that people who hold more negative aging stereotypes have a higher risk of heart problems about 40 years later, compared with people who have more positive feelings about age. But by changing our minds, we may also be able to change our health. “Positive age stereotypes seem protective of not experiencing these biomarkers,” says Becca Levy, lead author of the study and an associate professor of epidemiology and psychology at the Yale School of Public Health.
Levy’s study adds to the evidence that a more positive mind-set could make us more resilient in measurable ways. Eric Loucks, an assistant professor of epidemiology at Brown University, has shown that people with more “mindful dispositions”—which might be best defined as having an awareness of what you’re thinking and feeling in the moment—have significantly less body fat and also score higher on markers of heart health, compared with their peers. In another 2015 study, he discovered that people with high mindfulness scores were 86% more likely to have good cardiovascular health. Loucks’ team also plans to study whether mindfulness interventions will help people stick to doctor-recommended health regimens, like taking blood-pressure medication.
But if stress clearly accelerates biological aging, the opposite may also be true. Studies by Elissa Epel, a professor in the department of psychiatry at the University of California, San Francisco, have shown that mindfulness meditation can reduce stress and prevent people from ruminating in negative emotions, and some forms of meditation practice may even slow the biological signs of aging by stabilizing telomeres." -- Full article: http://time.com/4217061/its-the-little-things/
