Chronic exposure to discrimination may increase the risk of cardiovascular disease in African-American women, according to a study. The research found that higher levels of perceived discrimination were associated with greater calcium buildup in the arteries, highlighting the importance of addressing this stressor for heart health.
A study by Texas A&M University psychologist David H. Rosen found that watching a comedy video significantly increased participants' scores for hopefulness. The finding suggests humor can be a legitimate strategy for relieving stress and maintaining well-being while increasing hope.
The University of Ulster team found significantly increased levels of stress on two fault zones in Indonesia, including the Sunda trench and Sumatra fault. The analysis suggests a high risk of another earthquake, potentially triggering another tsunami.
A study by University of Colorado researchers found that rats with controlled stress exhibit reduced brainstem activation and behaviors similar to depression and anxiety. The prefrontal cortex sends inhibitory signals to the brainstem when stress is controllable, quelling alarm center activity.
A meta-analysis of 293 studies found that stress affects immunity in distinct ways, with short-term stress boosting natural immunity but chronic stress weakening it. Chronic stress is particularly damaging, especially for older or sick individuals, while acute time-limited stressors enhance quick energy-efficient responses.
A study found that less educated individuals face higher daily stress levels, which have more significant negative impacts on their health. The researchers discovered that daily stressors vary by socio-economic status, with those in disadvantaged positions experiencing greater health downturns.
A new study by Dr Stephen Joseph finds that emergency personnel in Northern Ireland experience high levels of psychological distress due to lack of control over their lives. Effective coping skills like anger management, emotional disclosure, and relaxation training can aid recovery from traumatic incidents.
Researchers found that individuals with two copies of the met form of the COMT gene had a more pronounced response to pain, while those with two copies of the val form reported less pain and fewer negative emotions. The study used PET brain imaging and controlled jaw pain to investigate the role of genetic variation in pain tolerance.
A new study suggests that Alzheimer caregivers' chronic stress may trigger excessive blood clotting, increasing the risk of coronary events such as heart attacks. The research found that high levels of stress were associated with higher fibrin D-dimer levels, even within normal ranges.
Researchers are studying 200 families in Baltimore to understand how children aged 9-14 are impacted when a parent loses their job. The study aims to identify coping mechanisms that can help prevent negative behavior and emotional problems, and will inform prevention programs to reduce stress.
Researchers found that recalling stressful events can lead to delayed blood pressure recovery and increased cardiovascular disease risk. Chronic stress is also associated with an elevated risk of later heart disease, likely due to prolonged strain on the cardiovascular system.
Research found that alcoholics exhibit blunted heart-rate responses to public speaking despite similar anxiety levels, indicating a disconnection between perception and physiological response. This impairment may contribute to social functioning and emotional experiences in individuals recovering from severe alcohol dependence.
Researchers at Ohio State University found a link between major stressors during pregnancy and the development of autism in children. The study, which included over 200 mothers, showed that stress levels for mothers of autistic children were nearly twice those of other mothers.
A study found that socially stressed mice were twice as likely to die after infection with a compound than physically stressed mice. The researchers believe social stress intensified the immune response, leading to toxic shock and organ damage.
New research reveals that uncontrollable stresses can severely affect the immune system by disrupting cytokine function and producing high levels of cortisol. In contrast, controlled stress responses result in brief, insignificant changes to immune activity.
