Mechanism behind Mind-Body Connection Explains How Chronic Stress Ages Immune System
Immune cells end in protective caps, called telomeres, that are shorter in persons suffering chronic stress. Shortened telomeres are a sign of premature aging. A new UCLA study suggests that the stress hormone cortisol is the culprit behind telomeres' early aging and offers a potential drug target for protecting the immune system against the wear and tear of long-term stress. ...

Vest To Measure Stress
How stressed are we? A sensor vest will soon be able to tell us. From sports training to computer games, the garment registers the electrical excitation of the muscles at any given time and determines the level of physical stress. ... Continue Reading
Scientist: Smiling can hurt your health
A German scientist has proved that people forced to smile and take on-the-job insults suffer more and longer-lasting stress that may harm their health. ... Continue Reading
Workplace stress affecting the sleep of US adults
Everyday strains of working life affect the sleep patterns of millions of Americans, a new study has found. ... Continue Reading
Long-term effects of alcohol abuse 'not limited to the liver'
Alcohol related health damage is not limited to just the liver, UK-based agency Alcohol Concern has warned. ... Continue Reading
Stress Hormones May Play New Role In Speeding Up Cancer Growth
New research here suggests that hormones produced during periods of stress may increase the growth rate of a particularly nasty kind of cancer. The study showed that an increase in norepinephrine, a stress hormone, can stimulate tumor cells to produce two compounds. These compounds can break down the tissue around the tumor cells and allow the cells to more easily move into the bloodstream. From there, they can travel to another location in the body to form additional tumors, a process called metastasis. ... Continue Reading
Stress Response Prevents Neurodegeneration
Multiple sclerosis (MS) is a debilitating immune-mediated disease of the brain and spinal cord (the central nervous system [CNS]). It is characterized by infiltration of the CNS by inflammatory cells and destruction of cells that reside in the CNS, known as oligodendrocytes (ODCs). The soluble factor IFN-gamma has a detrimental effect on disease in patients with MS. ... Continue Reading
Hostility and stress predict insulin resistance
Individuals with high stress and high hostility levels have an increased risk of developing insulin resistance, which occurs when the body's response to insulin begins to slow down and blood sugar levels begin to rise. People with insulin resistance have a high risk of developing diabetes. Previous research has shown that insulin resistance is associated with stress and certain personality factors, including hostility. However, the association between hostility and insulin resistance has been inconsistent, Dr. Jianping Zhang explained to Reuters Health. ... Continue Reading
Researchers Zero In On How The Body Regulates Its Response To Heat Stress
An elusive neurotransmitter pathway in the skin may have been isolated by University of Oregon researchers, a discovery that, if confirmed, would be a leap forward in understanding how temperature regulation occurs. In other words, they may have found a major player in the machinery that allows people to release body heat and stay cool. ... Continue Reading
Stress Triggers Relapse In Meth Abuse, Study Finds
Oregon Health & Science University research showing stress triggers a relapse of methamphetamine abuse in mice could be a step toward developing a drug to curb this frustrating obstacle to recovery. Results of the study, headed by Gregory Mark, Ph.D., associate professor of behavioral neuroscience in the OHSU School of Medicine, not only validate earlier studies on the effects of stress on drug relapse in humans, they also show a compound researchers used in the study to mimic metabolic changes that occur during periods of stress creates a useful model for studying this effect in the laboratory. ...
