by Peta Stapleton, The Conversation Credit: Shutterstock Almost two decades ago a colleague in the counseling field spoke of a technique that he said would help reduce stress. As a young academic and only a few years into my clinical career as a psychologist, I was keen to learn approaches that would help relieve stress. However,...
Neuroscience News2 hours ago Summary: Chronic stress accelerates the body’s epigenetic clock, however, those that can manage the effects of stress by strengthening their emotional regulation and self-control can slow the process. Source: Yale Scientists in recent years have developed ways to measure biological age by tracking chemical changes in DNA that occur naturally as people age...

If the game is further validated in larger studies, the researchers hope it would reduce the need for psychiatric...
By Benedette Cuffari, M.Sc.Reviewed by Emily Henderson, B.Sc. Both acute and chronic stress in many different forms can lead to a condition known as acute thymic atrophy, which can severely impact the health of the immune system. Thymus.

Researchers at The Ohio State University found that daily supplements that...
OSAKA CITY UNIVERSITY Increased allergic reactions may be tied to the corticotropin-releasing stress hormone (CRH), suggests a study published this month in the International Journal of Molecular Sciences. These findings may help clarify the mechanism by which CRH induces proliferation of mast cells (MC) – agents involved in the development of allergies in the human nasal...

A gene linked to unusually long lifespans in humans protects brain stem cells from the harmful effects of stress, according to a new study by Weill Cornell Medicine investigators. Studies of humans...
