Chronic inflammation as a hallmark of aging is like having a persistent, low-level fire burning in your body.

Inflammation is a natural response by your body’s immune system to fight off infections or repair damaged tissues. It’s like firefighters rushing to put out a fire in a building. However, as we age, sometimes this inflammation response can become overactive or stay turned on for a long time, even when there’s no immediate threat, like a fire that won’t go out.

This chronic or long-lasting inflammation can harm your body’s tissues and organs over time, leading to various age-related health problems, including heart disease, diabetes, and joint issues. It’s like the continuous, low-level fire gradually damaging a building.

So, chronic inflammation in aging refers to the persistent and harmful activation of the body’s immune response, which can contribute to the aging process and age-related diseases.
