How Aging Changes Your Immune System

Your immune system is a remarkable thing. Every minute of every day, it goes to work helping protect you from harmful substances like bacteria, viruses, toxins, cancer cells, and blood or tissues from another person. But just like in so many other areas, the immune system does not work as well as we get older. It becomes slower to respond and its ability to detect and correct defects also declines. In some cases, an autoimmune disorder may develop, where the immune system mistakenly attacks and destroys healthy body tissue.

The name 'immunosenescence' has been used to describe loss of immune functions in individuals 65 and older. This is why the older we get, the more susceptible we become to infections, inflammatory diseases and even cancer. Fortunately, there are steps you can take to boost your immune system as you age.
