Depression and inflammation form a bidirectional, self-reinforcing loop where depression primes exaggerated inflammatory responses to stressors, and inflammation promotes depressive symptoms via sickness behaviors and neurobiological changes.

Managing stress, sleep, and diet is not just about physical health; it directly impacts your mental health by lowering inflammation. If you have depression, addressing lifestyle factors that drive inflammation (like obesity or poor sleep) may break the cycle of worsening mood.

Depression and inflammation fuel one another. Inflammation plays a key role in depression’s pathogenesis for a subset of depressed individuals; depression also primes larger cytokine responses to stressors and pathogens that do not appear to habituate.
