Maternal stress is linked to altered development in areas of the brain associated with emotional development in their offspring.
Researchers have developed a new device that is able to detect cortisol levels through sampling ear wax.
Study reveals the body produces more cortisol when people are interrupted during work.
p11, a protein implicated in serotonin function, affects the initial release of cortisol in mice by modulating the activity of specific neurons in the hypothalamus. Previous studies found people with depression lave lower levels of p11 in their brains. The findings could help in the development of new treatments for depression and stress.
Cortisol levels are altered in people experiencing bereavement, causing possible consequences for health.
Low levels of the stress hormone cortisol and the GLIZ protein can trigger chronic inflammatory responses in the body, contributing to the aging process.
Chronic stress during pregnancy and elevated maternal cortisol levels have been linked to alterations in the gut microbiota of infants.
Using magnetic nanoparticles, researchers were able to stimulate the adrenal glands of rodents and control the release of stress-related hormones. The approach could be applied to humans to treat hormone-related disorders.
Chronic stress can affect a person's health and mental well being. Due to the COVID-19 virus, chronic stress is on the rise worldwide. Researchers examine the general and psychological health implications of chronic stress and suggest some methods we can adopt to keep our stress levels in check.
Study reveals a link between the nervous system and stem cells that regenerate pigment in hair follicles. When stressed, norepinephrine from the sympathetic nervous system causes melanocyte stem cells to activate excessively. The stem cells all convert into pigment-producing cells, prematurely depleting the reservoir. The findings explain the cellular and molecular links between stress and premature hair graying.
Stress and depression during pregnancy can affect the fetus' sex and increase the risk of preterm birth. Mothers who experienced physical and psychological stress during pregnancy were less likely to have a baby boy. During pregnancy, the fetuses of stressed mothers had reduced heart rate movement coupling, indicating slower central nervous system development.
Prenatal stress can have an epigenetic impact on the future mental health of offspring. Adult children of women who experienced prenatal stress are more vulnerable to stress and other mental health disorders.
