Cancer: The word alone evokes dread, anxiety, and fear. Accordingly, many women living with the disease and undergoing treatment experience chronic stress and depression. Scientists have demonstrated, in studies with rodents and humans, that stress can exacerbate cancer’s progression, but it wasn’t clear how. A new study, published in The Journal of Clinical Investigation, establishes […]Continue Reading ...
Human beings are not the only ones who suffer from stress – even microorganisms can be affected. Now, researchers from Chalmers University of Technology, Sweden, have devised a new method to study how single biological cells react to stressful situations. Understanding these responses could help develop more effective drugs for serious diseases. As well as […]Continue Reading ...
The first and most distinct consequence of daily mild stress is an increase in rapid-eye-movement (REM) sleep, a new study in the journal PNAS reports. The research also demonstrated that this increase is associated with genes involved in cell death and survival. REM sleep, also known as paradoxical sleep, is the sleep state during which […]Continue Reading ...
Female smokers experienced more stress and craving than male smokers after viewing cellphone-delivered stress-inducing images, report addiction researchers at the Medical University of South Carolina in Nicotine & Tobacco Research Gender matters when it comes to smoking cessation. Women are 31 percent less likely to quit smoking successfully, according to the National Institute of Drug […]Continue Reading ...
Patients with ALS frequently have a string of repeated DNA code in the cells of their brain, carrying hundreds to thousands of copies within the gene C9orf72. New research looks at what triggers these repeated sequences to eventually produce the toxic proteins that are associated with ALS, frontotemporal dementia, and other neurodegenerative diseases in patients […]Continue Reading ...
Scientists have revealed a key mechanism in worms that is involved in controlling the cell’s response to stress, a study in eLife reports. The discovery provides crucial new insights into a stress-response mechanism called unfolded protein response (UPR) and will help researchers understand the processes that protect cells, boost immunity and extend lifespan. The ability […]Continue Reading ...
Overweight is unhealthy. Yet more and more people in Germany are overweight, particularly children. As part of the LiNA mother-child study coordinated by the Helmholtz Centre for Environmental Research (UFZ), researchers were able to identify mother’s perceived stress during the first year of the child’s life as a risk factor for developing overweight in infancy. […]Continue Reading ...
A new study reveals that during stressful moments in the operating room, surgeons make up to 66 percent more mistakes on patients. Using a technology that captured the electrical activity of a surgeon’s heart, researchers found that during intervals of short-term stress, which can be triggered by a negative thought or a loud noise in […]Continue Reading ...
A new Personal Relationships study documents how the quality of a person’s romantic relationship and the life stress he or she experiences at two key points in early adulthood (at age 23 and 32) are related to sleep quality and quantity in middle adulthood (at age 37). Investigators found that people who have positive relationship […]Continue Reading ...

Having ancestors who were frequently exposed to stressors can improve one’s own immune response to stressors, according to Penn State researchers. The results suggest that family history should be considered to predict or understand the health implications of stress. “Prolonged stress typically suppresses immune function within an individual,” said Tracy Langkilde, professor and head of […]Continue Reading ...
Coronary heart disease (CHD) is the leading cause of death in the U.S., and African Americans are disproportionately affected. Prior studies have investigated how limited access to material resources due to financial hardship may influence health, but the association between that stress caused by financial hardship and coronary heart disease in African Americans has not […]Continue Reading ...
Credit: CC0 Public Domain Stressful or traumatic experiences occurring in a child’s earliest years—birth to age 5—have been linked to reduced hippocampal volume in adolescence, according to a new Vanderbilt University report published in Developmental Science. “These findings tell us that there may be a ‘sensitive period’ in which stress is more likely to affect […]Continue Reading ...
The immune system is composed of a wide range of different immune cells each with dedicated functions. Natural killer T cells form a specialized immune cell that protects against a variety of diseases such as cancer, autoimmunity, metabolic disease or certain infections such as Lyme disease. This is because of their ability to make very […]Continue Reading ...
Stress related to social stigma may be the reason why autistic people experience more mental health problems than the general population, dispelling past theories that the condition itself is the origin of such distress. In the first study of its kind, published in the Journal of Society and Mental Health, researchers from the University of […]Continue Reading ...
