Summary: New findings suggest common concepts cited in textbooks may need to be adjusted. Source: University of Bristol. Stress is a common problem often resulting in poor health and mental disorders. New research has revealed that current concepts on how stress hormones act on the brain may need to be reassessed.
It is thought that disturbances in the action of stress hormones play a key role in causing mental disorders, like major depression and post-traumatic stress disorder (PTSD). Learning to cope with stressful events is known to require changes in the expression of genes in the hippocampus, a limbic brain region involved in learning and memory. Such changes in gene expression are brought about by stress-induced glucocorticoid hormones acting via receptors that can directly bind to genes and alter their expression.

Making Art Reduces Stress Hormones – Neuroscience News.
Summary: No matter whether you’re a Rembrandt or can just about manage to draw a stick figure, creating art can help to reduce cortisol levels, a new study reports. Source: Drexel University. Whether you’re Van Gogh or a stick-figure sketcher, a new Drexel University study found that making art can significantly reduce stress-related hormones in your body. Although the researchers from Drexel’s College of Nursing and Health Professions believed that past experience in creating art might amplify the activity’s stress-reducing effects, their study found that everyone seems to benefit equally. “It was surprising and it also wasn’t,” said Girija Kaimal, EdD, assistant professor of creative arts therapies. “It wasn’t surprising because that’s the core idea in art therapy: Everyone is creative and can be expressive in the visual arts when working in a supportive setting. “Biomarkers” are biological indicators (like hormones) that can be used to measure conditions in the body, such as stress.

The death of a life partner may trigger an irregular heartbeat, itself potentially life-threatening, according to research into the risk of dying from a broken heart. A trawl of data on nearly one million Danish people showed an elevated risk, lasting about a year, of developing a heart flutter.
Those under 60 whose partners died unexpectedly were most in peril. The risk was highest “8-14 days after the loss, after which it gradually declined”, said a study published in the online journal Open Heart on Wednesday. “One year after the loss, the risk was almost the same as in the non-bereaved population.” Much research has focused on explaining the observed phenomenon of people dying soon after their life partner. Several studies have shown that grieving spouses have a higher risk of dying, particularly of heart disease and stroke, but the mechanism is unclear. Researchers in Denmark used population data collected between 1995 and 2014 to search for a pattern.
