Inflammation has a branding problem. We know it as the redness around a cut or the swollen ankle after a twist — a visible, acute, and temporary response. That version of inflammation is your friend. It’s a precisely orchestrated immune response that mobilizes healing resources to a site of damage, then resolves once the job is done.
But there’s another version. Quiet, persistent, low-grade, and never fully resolving. This is the inflammation that researchers increasingly believe lies at the heart of the aging process itself. And unlike the acute kind, it’s almost entirely invisible — until the damage it causes is not.
Introducing Inflammaging
The term “inflammaging” was coined by Italian immunologist Claudio Franceschi in 2000 to describe the chronic, low-grade inflammatory state that develops with advancing age. It’s not a disease — it’s a biological shift. As we age, basal inflammatory tone rises, pro-inflammatory cytokines like IL-6, TNF-alpha, and CRP become chronically elevated, and the immune system settles into a persistent state of low-level activation.
This isn’t random. Inflammaging has identifiable drivers: the accumulation of senescent cells (damaged cells that refuse to die but keep secreting inflammatory signals), gut microbiome changes that increase inflammatory lipopolysaccharide (LPS) in circulation, declining levels of anti-inflammatory hormones, and the buildup of cellular debris that the aging immune system struggles to clear.
What Inflammaging Does to the Body
The downstream consequences of chronically elevated inflammation are broad and serious. Elevated inflammatory markers are associated with virtually every major age-related disease — cardiovascular disease, type 2 diabetes, Alzheimer’s, certain cancers, and osteoporosis all have documented inflammatory components.
Beyond disease risk, inflammaging directly accelerates the cellular aging process. It impairs stem cell function and regenerative capacity. It disrupts hormonal signaling. It increases oxidative stress. It interferes with DNA repair systems. And as noted earlier, it consumes cellular energy — diverting ATP away from the metabolic and repair processes that sustain vitality.
The Senescent Cell Problem
A particularly important contributor to inflammaging is the accumulation of senescent cells — cells that have stopped dividing but remain metabolically active and secrete a cocktail of inflammatory molecules called the senescence-associated secretory phenotype (SASP). In youth, the immune system efficiently clears senescent cells. With age, the clearance system becomes less efficient, and senescent cells accumulate in tissues throughout the body, broadcasting inflammatory signals that degrade the surrounding cellular environment.
Reducing Inflammaging: What the Research Supports
The evidence base for reducing inflammaging points to several consistent approaches. A Mediterranean-style diet rich in anti-inflammatory compounds — polyphenols, omega-3 fatty acids, and fiber — is among the best-documented. Regular moderate exercise reduces inflammatory markers systemically. Quality sleep allows the lymphatic system to clear cellular debris and reduces inflammatory cytokine production. Stress management matters, as cortisol dysregulation drives inflammatory tone upward.
At the cellular level, photobiomodulation technologies have demonstrated the ability to reduce pro-inflammatory cytokines and shift the cellular environment toward an anti-inflammatory, repair-oriented state — directly addressing one of the key mechanisms through which aging accelerates.
Inflammation is quietly running the clock faster than it needs to. If you’re curious about the tools that work at the cellular level to slow that process, the Code of Aging is where to start.
What is inflammaging?
Inflammaging is the chronic, low-grade inflammatory state that develops with advancing age. Unlike acute inflammation (which resolves), inflammaging is persistent and drives accelerated biological aging and increased disease risk.
What causes inflammation to increase with age?
Key drivers include the accumulation of senescent cells that secrete inflammatory molecules (SASP), gut microbiome changes, declining anti-inflammatory hormones, and the buildup of cellular debris the aging immune system struggles to clear.
How does chronic inflammation cause aging?
Chronic inflammation impairs stem cell function, disrupts DNA repair, increases oxidative stress, consumes cellular energy, and is associated with virtually every major age-related disease. It accelerates biological aging by degrading the cellular environment needed for repair and regeneration.
What are senescent cells and why do they cause inflammation?
Senescent cells are damaged cells that stop dividing but remain active, secreting inflammatory molecules known as SASP. As clearance efficiency declines with age, these cells accumulate and create a persistent inflammatory environment in surrounding tissues.
How can you reduce inflammaging naturally?
A Mediterranean-style diet, regular moderate exercise, quality sleep, and stress management all reduce inflammatory markers. At the cellular level, photobiomodulation technologies can reduce pro-inflammatory cytokines and support an anti-inflammatory cellular environment.
Can photobiomodulation reduce inflammation with age?
Yes — multiple studies document PBM’s ability to reduce pro-inflammatory cytokines and shift tissues toward an anti-inflammatory state. This makes it a relevant tool for managing the chronic inflammatory load that accumulates with age.
