Chronic stress increases inflammaging
Like stress, inflammation is a normal part of the human experience. Itβs the bodyβs main way of identifying harmβwhether from pathogens or injuryβand initiating the healing process. Acute, or short-term inflammation, is essential to our health. But when that same inflammation becomes constant, it can actually do more harm than good. [4]Age-associated chronic inflammation, also known as inflammaging, is associated with alterations in the bodyβs immune response. Itβs now understood that these alterations occur when the bodyβs immune response is disrupted due to immunosenescence. This continuous, systemic inflammation can contribute to the development of several diseases including atherosclerosis, diabetes, and hypertension.In addition to its link with stress-induced cellular senescence, inflammaging is also believed to be directly tied to chronic psychological stress by altering levels of cytokines, small proteins that are important in cellular signaling. During the aging process, the body experiences a decrease in anti-inflammatory cytokines, and a simultaneous increase in pro-inflammatory cytokines, leading to overall higher levels of inflammation. Scientists now believe that chronic psychological stress further stimulates pro-inflammatory cytokines. In fact, some studies have shown that antidepressants, which are used to reduce psychological stress, actually reduce enhanced levels of these pro-inflammatory cytokines. [2]This data indicates that living in a constant state of psychological stress can actually accelerate the inflammaging that you might normally experience as a result of the aging processβhastening the cellular damage caused by inflammation so that you actually age more quickly.
