Cortisol is a hormone made by the adrenal cortex (the outer layer of the adrenal gland). It helps the body use glucose (a sugar), protein, and fats. Cortisol made in the laboratory is called hydrocortisone. It is used to treat many conditions, including inflammation, allergies, and some cancers. Cortisol is a type of glucocorticoid hormone.
The continuous daylight conditions of summer in Antarctica are known to interfere with physiological functions such as sleep patterns and the release of melatonin, a hormone associated with circadian rhythms and sleep.
Stress and anxiety are widely believed to contribute to drinking. Alcohol is thought to reduce tension caused by stress (the "flight or fight" response) as well as alleviate the unpleasant symptoms of anxiety (anticipation of the unpredictable, impending threats).
Up to 20 percent of U.S. veterans who served in Iraq and Afghanistan developed symptoms of post-traumatic stress disorder from trauma experienced during wartime, but new neuroscience research from The University of Texas at Austin suggests some soldiers might have a hormonal predisposition to experience such stress-related disorders.
While fear and aggression tend to curb our appetite, sadness and frustration seem to stimulate it. A project funded by the Austrian Science Fund FWF looks into the connections between mood and overeating in healthy and bulimic individuals.
Many people suffer from pain when they fly but that may soon be a thing of the past. A new study from Aalborg University may have discovered the mechanisms responsible, opening the door to developing a cure.
Research led by University of Birmingham scientists has found that people suffering from the adrenal disorder known as Addison's disease suffer from an immune system defect which makes them prone to potentially deadly respiratory infections.
In this age of highly realistic computer games and increasingly popular social networks, social exclusion in virtual worlds is becoming more and more socially significant, as is demonstrated by the growing number of "cyber mobbing" cases.
In addition to the classic stress response in our bodies - an acute reaction that gradually abates when the threat passes - our bodies appear to have a separate mechanism that deals only with chronic stress.
Studies have suggested that married people are healthier than those who are single, divorced or widowed. A new Carnegie Mellon University study provides the first biological evidence to explain how marriage impacts health.
A specific gene that helps form memories from traumatic events can be manipulated -- and in doing so may actually help prevent post-traumatic stress disorder (PTSD), according to a new study led NYU Langone Medical Center that recently published in Neuropharmacology.
An expectant mother's exposure to the endocrine-disrupting chemical bisphenol A (BPA) can raise her offspring's risk of obesity by reducing sensitivity to a hormone responsible for controlling appetite, according to a mouse study published in the Endocrine Society's journal Endocrinology.
Genetic mutations of the Armc5 gene disrupt foetal development and compromise the immune response.
The name of the gene is Armc5, for Armadillo repeat containing 5. Until now, its function was unknown. After 10 years of research, a team at the University of Montreal Hospital Research Centrehas succeeded in deleting this gene in experimental mice and discovered that its loss gives rise to a heretofore unidentified syndrome.
A new study shows that individuals exposed to a simulated cyber-terror attack had significantly increased levels of the stress hormone cortisol in their saliva compared to a control group.
Whilst it is true that women and men respond differently to stress, current neuroscientific research only partially confirms traditional gender stereotypes.
For most people, cortisol, the vital hormone that controls stress, increases when they wake up. It's the body's way of preparing us for the day.
Born too soon, she weighed just over 1 pound at birth and spent the first three months of her life in the neonatal intensive care unit, fighting to live.
A new Finnish study supports food recommendations for families with children in that women should avoid consuming large amounts of liquorice during pregnancy. The limit for safe consumption is not known.
James Cook University scientists have made a disturbing finding about some young Indigenous people's biological reaction to stress, but one that could help close the health gap for indigenous people.
A complete clinical and genetic profile of a rare inherited disorder, steroid 11-hydroxylase deficiency, which can cause genital masculinization in females, is being reported by an international group of researchers led by investigators at the Icahn School of Medicine at Mount Sinai.
