Inflammation is the body’s natural healing response, but when it becomes chronic and doesn’t turn off, it can contribute to serious conditions like heart disease, diabetes, and cancer. While some chronic inflammation is driven by autoimmune disease or factors beyond our control, healthy habits like diet, exercise, and sleep can still help support the body and reduce long-term health risks.
