Imagine a very small, almost invisible fire. It does not burn enough to hurt you, it does not smoke enough to make you cough. But it is always alight, day and night, for years. What happens to everything around it?

This is inflammaging: a chronic, silent, low-grade inflammation that tends to increase with age even in the absence of obvious infections or diseases. The name is a blend of the English words inflammation and aging, and it is no accident: research over the last twenty years has shown that these two processes are more closely linked than previously thought.

Inflammation that is good and inflammation that is bad

Inflammation is not the enemy. It is one of the most powerful defence mechanisms we have. When you cut your finger, when you catch flu, when your muscles overexert themselves, the inflammatory system activates, intervenes and repairs. Without it, we would not be here.

The problem arises when this system remains active even without a precise reason, at a low but continuous level. Not enough to produce clear symptoms, no fever, no acute pain, no visible swelling. But enough to interfere, in the long run, with the functioning of the cells, tissues, microcirculation, and metabolism.

The researchers Franceschi and Campisi, among the first to study this phenomenon systematically, described it as one of the most relevant processes in biological ageing. Not the only cause, ageing is too complex to have only one, but a significant and often underestimated contribution.

How can you recognise it? (Spoiler: it is not easy)

Here is the practical problem: inflammaging has no specific symptom. People who have it often simply feel ‘less fit’. Tired sooner than usual. With less energy. Slower to recover after exertion or a difficult night. With a general sense of ‘heaviness’ that is hard to explain to the doctor because it does not show up as any abnormal test result.

This does not mean that anyone who feels this way has inflammaging. These symptoms can have many causes, and only a medical assessment can point you in the right direction. But it does mean that this kind of silent inflammation is worth knowing about, because it could be one of the keys to understanding why the body, at a certain point, starts to respond differently.

Can something be done?

The short answer is yes, but it requires a serious approach. There is no anti-inflammaging pill, and anyone selling one is probably selling hot air. What the most advanced longevity medicine is exploring is how to act on the biological regulation mechanisms that allow inflammation to become chronic, working not on the symptom but on the processes that generate it.

The model REAC Inside Blue Zone fits into this approach. The REAC ACT-iBZ protocol was developed to support the modulation of chronic inflammatory processes within a structured medical pathway aimed at the progressive recovery of physiology. The aim is not to switch off inflammation, which is essential to life, but to help the body regain a more efficient balance.
