Cortisol may be the Swiss Army knife of hormones in the human body-just when scientists think they understand what it does, another function pops up. While many of these functions are understood for adults, much less is known about how cortisol operates in babies and toddlers, especially when it comes to an important phenomenon called the cortisol awakening response, or CAR. For the first time, psychology researchers from the University of Georgia Franklin College of Arts and Sciences have...

Stress-related disorders are often linked to people working in the line of fire. In a study led by researchers at NYU Langone Medical Center in collaboration with the San Francisco VA Medical Center and the University of California, San Francisco, police recruits were assessed during academy training before critical incident exposure and provided salivary cortisol at first awakening and after 30 minutes. Police academy recruits who showed the greatest rise in the stress hormone cortisol after...

Study finds working in shifts associated with elevated levels of stress hormone cortisol A recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM) found that shift work at a young age is associated with elevated long-term cortisol levels and increased BMI. Previous studies have shown that long-term elevated cortisol levels lead to increased abdominal obesity, hypertension, diabetes and cardiovascular risk. Shift work,...

The potentially lasting implications of day-to-day couple conflict on physical and mental well-being are revealed in a study published today in the journal Personal Relationships.

Day-care-center-based child care and insensitive parenting might have lasting effects, U.S. researchers suggest. The Eunice Kennedy Shriver National Institute of Child Health and Human Development tracked about 1,000 children from one month through mid-adolescence to examine the effects of child care in children's first few years of life on later development. The researchers observed children in and out of their homes and when the children were 15, they measured their levels of awakening...

The relationship between a young child and his or her teacher can affect the levels of the stress hormone cortisol in the child, U.S. researchers believe. Researchers at Washington State University, Auburn University and the Pennsylvania State University said cortisol, a stress hormone in humans, tends to be at its highest levels in the early morning and gradually declines over the course of the day. The researchers found that children in classrooms with about 10 children were more likely to...

By Clementine Wallace NEW YORK (Reuters Health) - It is simplistic to suggest that lowering cortisol levels will promote weight loss, as some television ads claim, according to researchers at the Oregon Health and Science University in Portland. In their study, published in the Journal of Clinical Investigation, the scientists show that the hormone isn't the major factor involved in weight gain and fat distribution, and might actually come into play at a secondary level. "There's no...
