People with rheumatoid arthritis or type 1 diabetes who experience higher levels of cumulative physiological stress have a significantly higher risk of dying from any cause compared to those with...
Mechanism
Synthesis from 1 study
Long-term stress keeps the body's stress system turned on, which breaks the natural off-switch for inflammation. This lets inflammation keep going and damages organs, especially in people who already have autoimmune diseases. The more stress and the worse the genetics, the faster the damage...
Most probable mechanism
Long-term stress keeps the body's stress response system constantly turned on, which overwhelms the system that normally turns off inflammation. This causes the body to stop responding to its own anti-inflammatory signals, allowing inflammation to persist and damage tissues. In people with existing autoimmune diseases, this ongoing inflammation worsens organ damage and increases the chance of death.
Persistent psychological and environmental stressors cause sustained activation of the hypothalamic-pituitary-adrenal axis and sympathetic nervous system
Sustained stress exposure reduces sensitivity of glucocorticoid receptors in immune cells, impairing the body's ability to suppress inflammation
Glucocorticoid resistance permits unchecked production of pro-inflammatory cytokines such as interleukin-6 and tumor necrosis factor-alpha, and expansion of pathogenic T-cell populations
Chronic low-grade inflammation and failure of inflammatory resolution promote autoimmune activation in target tissues such as pancreatic islets, joints, and gut mucosa
Tissue-specific autoimmune destruction accelerates in individuals with high genetic susceptibility due to epigenetic reprogramming of immune cells that lowers activation thresholds
Unresolved inflammation and accelerated tissue damage increase organ failure and systemic complications, elevating all-cause mortality risk
Less supported by current evidence, but not ruled out
Low intake of omega-3 fatty acids limits the body's ability to stop inflammation after it starts, allowing inflammation to continue longer and cause more damage in people under chronic stress.
Low levels of omega-3 fatty acids in cell membranes reduce competition with arachidonic acid for inflammatory enzymes
Reduced omega-3 availability decreases production of specialized pro-resolving mediators such as resolvins and protectins
Impaired resolution of inflammation allows persistent cytokine activity and immune cell infiltration in target tissues
Lack of regular movement allows the stress response system to remain overactive and prevents muscles from releasing signals that calm inflammation, making tissue damage worse under chronic stress.
Low physical activity reduces vagal tone and fails to suppress sympathetic nervous system hyperactivity
Absence of exercise reduces release of anti-inflammatory signaling molecules from skeletal muscle
Reduced myokine signaling and persistent sympathetic drive maintain systemic inflammation and impair immune regulation
