What Is Inflammaging? Understanding Chronic Inflammation and Aging

Inflammaging refers to chronic, low-grade inflammatory signaling that develops gradually with age. Unlike acute inflammation—which is protective and necessary for healing—inflammaging is subtle, persistent, and systemic. It is increasingly recognized as a central feature of biological aging.

Researchers in healthy aging science are increasingly studying how chronic low-grade inflammation contributes to cellular decline.

Definition:

Inflammaging is characterized by persistent low-level inflammation, elevated inflammatory signaling markers, reduced resolution, and increased oxidative stress.

Why It Matters:

Contributing factors include cellular debris accumulation, mitochondrial stress, immune remodeling, environmental exposure, and oxidative imbalance. These factors reinforce each other over time and may reduce adaptive resilience.

These changes are strongly connected to chronic inflammatory patterns that persist over time.

Adaptive Perspective:

Healthy aging research increasingly focuses on maintaining immune balance rather than suppressing inflammatory processes entirely.

Over time, these processes influence immune aging changes, shaping how the body responds to stress.

FAQ:

What is inflammaging?

Chronic low-grade inflammation is associated with aging.

Is inflammation always harmful?

No. Acute inflammation is protective; chronic dysregulation is the issue.

Can lifestyle influence inflammaging?

Yes. Diet, stress, sleep, and environmental exposures matter.
