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.
It's perhaps one of the most common emotions to feel in a relationship, but one that's virtually untouched when it comes to studying relationships in monogamous primate species.
One in three 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.
Being under stress diminishes our abilities to predict new dangers that we face, a team of psychology researchers finds. Its work runs counter to the conventional view that stress enhances our ability to detect and adjust to these changing sources of threat.
A newly-discovered reflex arc mediates a process which leads to a disruption in the hormones secreted by the adrenal glands which, in turn, results in an increased susceptibility to bacterial infections.
egg health innovations (previously part of Virgo Health) has launched a new wearable technology product which provides a fully immersive, first person patient insight experience. Named “Virtual Mile” it allows someone to authentically understand another person by experiencing the world from a virtual first person vantage point, conceived from a need to capture greater insights in sensitive conditions and rare diseases.
People with a specific variation in the CLOCK gene have more migraines under financial stress. This work, the first time that the genetics of circadian rhythms has been shown to have an effect on migraine, is presented at the ECNP conference in Paris.
Around 75% of children and adults with Attention Deficit Hyperactivity Disorder (ADHD) also have sleep problems, but until now these have been thought to be separate issues.
Sleep apnea, left untreated for even a few days, can increase blood sugar and fat levels, stress hormones and blood pressure, according to a new study of sleeping subjects.
Many people report positive health effects from practicing yoga and meditation, and experience both mental and physical benefits from these practices.
Gut microbes have been in the news a lot lately. Recent studies show they can influence human health, behavior, and certain neurological disorders, such as autism.
One downside to medical sensors that test human sweat: you have to sweat. Sweating from exertion or a stifling room temperature can be impractical for some patients and unsafe for others.
Numerous studies have shown a relationship between high-crime communities and the academic performance of children who live within them.
Researchers at The University of Texas at Dallas are getting more out of the sweat they've put into their work on a wearable diagnostic tool that measures three diabetes-related compounds in microscopic amounts of perspiration.
Australian researchers have for the first time discovered that a specific type of irritable bowel syndrome is associated with exhaustion of the immune system in patients.
AUSTRALIAN scientists have discovered that exhausted immune cells point to a specific type of irritable bowel syndrome (IBS).
Stress, especially in women, is increasingly being recognized as a major risk factor for coronary heart disease, a condition in which blood vessels to the heart are blocked by plaque buildup or inflammation.
In a new review of the effects of acute exercise published in Brain Plasticity, researchers not only summarize the behavioral and cognitive effects of a single bout of exercise, but also summarize data from a large number of neurophysiological and neurochemical studies in both humans and animals showing the wide range of brain changes that result from a single session of physical exercise.
Cannabis smokers often report that they use the drug to relax or relieve stress, but few studies provide clinical evidence of these effects.
The human body works according to a roughly 24-hr cycle. It is controlled by a master clock in the brain and by peripheral clocks in other parts of the body, which are synchronized according to external cues such as light.
The feeling of constantly being on edge, always having to take care of everything, not being able to find a balance: If an expectant mother is strongly stressed over a longer period of time, the risk of the unborn child developing a mental or physical illness later in life - such as attention deficit hyperactivity disorder (ADHD) or cardiovascular disease - increases.
