Researchers found that individuals with greater neural sensitivity to social rejection exhibit increased inflammatory activity, which can increase the risk of disorders such as asthma, rheumatoid arthritis, and depression. Chronic inflammation can also lead to cardiovascular disease and certain types of cancer.
Forests have been shown to decrease blood pressure, heart rate and muscle tension in natural settings, while also reducing depression, anger and ADHD symptoms.

A study published in BMC Public Health found that stress caused by the 9/11 attacks led to a spike in male fetal deaths and lower birth rates for boys in December 2001. The research suggests that societal shock may affect male pregnancies, potentially due to a mechanism conserved by natural selection.
A systematic review found that Tai Chi is associated with reduced stress, anxiety, and depression, as well as improved mood and self-esteem. However, the quality of the studies was generally modest, highlighting the need for more high-quality randomized trials to confirm these findings.
A recent study found that family caregivers with dementia experience a wide range of stressors, including behavior issues and financial strain. While existing interventions focus on specific stressors, research suggests that a one-size-fits-all approach is insufficient, highlighting the need for personalized interventions.
Researchers have discovered a link between stress, anxiety, and metabolic changes that can lead to type 2 diabetes. The study found that increasing the activity of a single gene in the brain causes mice to exhibit anxious behavior and develop symptoms associated with type 2 diabetes.
Research suggests that trauma from war increases asthma risk, with twice the likelihood of development in those most traumatised. A study of 2000 Kuwaiti civilians aged 50-69 found a direct correlation between trauma and asthma risk.

The programme highlighted a significant gap in traditional GP referrals for mental healthcare after terrorist attacks.
A study of Rwandan genocide survivors found that genetic variations in the catechol-O-methyltransferase (COMT) gene affect PTSD risk. Survivors with certain genetic markers showed increased resilience to stress-related problems, while others were more vulnerable. The findings provide new insights into the complex relationship between t...
A study finds that fetuses exposed to high levels of stress hormone cortisol may have trouble paying attention or solving problems later on. However, if mothers provide sensitive care during infancy and toddlerhood, the negative link disappears almost entirely.
Researchers found that depression is associated with spikes in cortisol levels for both boys and girls after stress tests. However, higher cortisol reactions to stress are only linked to obesity in girls. Early treatment of depression could help reduce stress and control obesity in this demographic.
A study published in Diabetes Care found that brain function slows in individuals with type-2 diabetes and high stress hormone cortisol levels. Higher cortisol levels have been associated with cognitive decline in this population.

Researchers found a 3.3-fold increase in cancer risk among isolated rats with naturally occurring mammary tumors. Isolation and stress led to higher production of corticosterone, a stress hormone, and increased tumor growth. The study suggests a causal relationship between social interaction and disease.
A genetic variation in oxytocin's receptor has been linked to both empathetic ability and stress reactivity in a study of college students. Those with the GG allele showed lower heart rate responses to stress tests and performed better on a test measuring empathy.

The study suggests that addressing problem behaviors in autism is crucial for family well-being and early intervention.
A study found that stress is linked to weight gain, particularly in women who experience strained family relationships and limited life circumstances. Stress reduction strategies, such as access to weight-loss programs and flexible work schedules, may help mitigate this effect.
A study found that mental stress causes vasodilation in healthy subjects, resulting in a net increase in brain blood flow. However, individuals with high blood pressure showed no vasodilation or change in brain blood flow under similar conditions.

A study published in the Journal of Traumatic Stress found that at least half of Afghan school children have developed PTSD due to traumatic experiences. The research highlights the need for interventions addressing not only war experiences but also family disturbances and community factors.
Teenage girls experience increased stress levels, with seven out of ten suffering from stress. To withstand this, girls rely on various sources of strength including emotional support, controlling their daily lives, and engaging in recreational activities.
Over 30 years, middle-aged women's levels of perceived mental stress have increased significantly, while their blood pressure has decreased. This is according to a Swedish study that followed 1,462 women from the 1960s to the 2000s.
New research published by King's College London reveals that experiencing 'cruel, inhuman, and degrading treatment' (CIDT) is associated with higher rates of posttraumatic stress disorder (PTSD) than physical torture. Survivors reported an average of 21 stressor events during detention or captivity, highlighting the severity of CIDT.
Research suggests that childhood physical and mental stress may have long-lasting negative impacts on adult health. Effective strategies for reducing chronic morbidity and premature death are needed.
Researchers identify three key findings: toxic stress disrupts brain architecture, major risk factors include poverty and abuse, and relieving this stress can improve individual well-being and societal health. The report proposes promising applications in health policy and clinical practice to address these disparities.
Integrative body-mind training (IBMT) alters blood flow and electrical activity in the brain, breathing quality, and even skin conductance, allowing for a state of relaxation, calmness, and reduced stress.
