Examples of interaction between psychosomatic diseases and immunity
clearly demonstrate how psychological states and emotional stress can rebuild the immune system and directly affect physical health. Recent studies have confirmed that patients with severe depression often have increased levels of inflammatory markers such as C-reactive protein (CRP) and interleukins (IL-6), which explains their increased susceptibility to cardiovascular disease. Other studies have shown that chronic anxiety and post-traumatic stress disorder (PTSD) are associated with impaired natural killer (NK) activity and a reduced ability to fight off viral infections — the flu, for example. In the field of oncology, research has confirmed that chronic psychological stress weakens the immune system’s anti-tumor response through excessive secretion of stress hormones such as cortisol, which accelerates the growth of certain tumors or reduces the effectiveness of immunotherapy. Recent studies have also shown that chronic skin diseases such as psoriasis and eczema are exacerbated by psychological stress due to imbalanced immune system activation and increased skin inflammation. In the area of wound healing, it has been shown that in people experiencing severe psychological stress, healing is significantly slower due to a decrease in the local immune response. These examples demonstrate that the link between psychosomatic diseases and immunity is not just theoretical, but scientifically proven, paving the way for the development of comprehensive therapeutic interventions that simultaneously act on both the psychological and immune systems to achieve better treatment outcomes.
