Pessimism leads to the loss of immune cells and accelerated aging. Harvard data confirms this: high pessimism correlates with a lack of naive T-CD4+ lymphocytes Scientists analyzed data from 7250-7870 participants and found that a high level of pessimism is directly related to a lack of naive T-CD4+ lymphocytes - cells that regulate the immune response - and accelerated biological aging of cells. The logic is this: a constant and persistent negative outlook on life causes chronic stress. In response, the body produces cortisol and other stress hormones. Long-term activation of this system can indeed have a negative effect on the immune system, including leading to depletion of the pool of naïve cells (when they are consumed too actively or dying) and contribute to the accumulation of cellular damage, which accelerates biological aging. The point is not that pessimism itself "destroys" the immune system. Instead, chronic stress and a negative worldview are a risk factor that exacerbates other stresses (lack of sleep, unhealthy lifestyle, social difficulties), and together they damage the body's defenses.
