In a study of more than 400 adults with normal blood pressure, those who had high levels of stress hormones detected in their urine were more likely to develop high blood pressure over the next 6-7 years. Higher levels of the stress hormone cortisol were also linked to an increased risk of cardiovascular events, including heart attack and stroke.

Adults with normal blood pressure and high levels of stress hormones were more likely to develop high blood pressure and experience cardiovascular events compared to those who had lower stress hormone levels, according to new research published today in Hypertension, an American Heart Association journal.

Studies have shown that cumulative exposure to daily stressors and exposure to traumatic stress can increase cardiovascular disease r...

Abnormal levels of stress hormones such as adrenaline and cortisol are linked to a variety of mental health disorders, including depression and posttraumatic stress disorder (PTSD). MIT researchers have now devised a way to remotely control the release of these hormones from the adrenal gland, using magnetic nanoparticles.

This approach could help scientists to learn more about how hormone release influences mental health, and could eventually offer a new way to treat hormone-linked disorders, the researchers say...

Taking at least twenty minutes out of your day to stroll or sit in a place that makes you feel in contact with nature will significantly lower your stress hormone levels. That’s the finding of a study that has established for the first time the most effective dose of an urban nature experience. Healthcare practitioners can use this discovery, published in Frontiers in Psychology, to prescribe ‘nature-pills’ in the knowledge that they have a real measurable effect.

“We know that spending time in nature reduces stress, but until now it was unclear how much is enough, how often to do it, or even what kind of nature experience will benefit us,” says Dr...

Ridlon and endocrinologist David Morris explain the mechanism that links gut bacteria to hypertension in humans.

1 in 3 American adults suffers from high blood pressure, or hypertension. The disease can be passed down in families, and certain lifestyle factors such as smoking, high-sodium diets, and stress can increase the risk. In recent years, scientists have discovered that certain gut bacteria may contribute to hypertension, as well. In a few studies, when gut bacteria were killed off with antibiotics, patients with hypertension saw a drop in blood pressure. And when gut bacteria were transplanted from hypertensive people into normal mice, they developed high blood pressure...
