Most people associate inflammation with something obvious. Fever. Swelling. Pain. But low-grade inflammation rarely announces itself that clearly. It often appears as slower recovery, persistent stiffness in the morning, or that quiet fatigue that never fully lifts. Nothing dramatic. Nothing urgent. And yet, something feels slightly off.
Over the past decade, immunology has shifted its focus. The question is no longer only how inflammation starts, but how it ends. Researchers such as Charles Serhan have described a distinct “resolution phase,” an active biological process involving specialized pro-resolving mediators derived from omega-3 fatty acids. These molecules do not suppress inflammation in the traditional sense. They help the body complete the cycle and return tissues to balance. If this resolution phase is inefficient, inflammatory signaling may linger longer than necessary, even when the original trigger is gone (Serhan, 2020, Nature Reviews Immunology).
This distinction matters. Chronic low-grade inflammation, sometimes referred to as inflammaging, appears to be associated with visceral fat accumulation, disrupted sleep, metabolic stress, and reduced muscle mass. Franceschi and colleagues have explored how this background immune activation increases with age and may influence long-term health trajectories (Franceschi et al., 2018, Nature Reviews Endocrinology). It does not necessarily feel like illness. It may simply feel like reduced resilience.
So what can an individual realistically influence? Evidence suggests several practical levers. Adequate sleep supports circadian regulation of immune responses. Resistance training stimulates myokines that appear to modulate inflammatory balance, reinforcing the idea that skeletal muscle functions as an endocrine organ (Pedersen, 2019, Physiological Reviews). Omega-3 fatty acids provide substrates for pro-resolving mediators, although optimal dosing and individual response remain debated (Calder, 2020, Nutrients). Reducing visceral fat may also lower persistent inflammatory signaling. None of these interventions eliminate inflammation. That is not the goal. The aim is to support the body’s ability to finish what it starts.
If recovery after training consistently stretches longer than expected, if minor aches linger, or if energy rarely feels fully restored, it may be worth paying attention. Not with alarm. With curiosity. In many cases, improving resolution is less about aggressive suppression and more about restoring rhythm.
