Aging has a big effect on our immune system, which is the body's way of fighting off illness. This change can lead to health problems. Here are some important things to know:
Immunosenescence: As people get older, their immune system goes through a change called immunosenescence. This means that the immune system doesn’t work as well as it used to. It affects both parts of the immune system. For example, the body makes fewer new T cells, and the older ones may not react well to germs.
Increased Inflammation: Aging often comes with a condition known as "inflammaging." This means there is mild, long-lasting inflammation in the body. This can make diseases worse, like arthritis, heart problems, and brain disorders. When certain substances in the body that cause inflammation build up, it can lead to damage over time.
Vaccination Efficacy: Older adults don’t respond as well to vaccines. For example, when seniors get the flu shot, it doesn't work as effectively for them. This shows that older people might need special vaccines or stronger doses to help protect their immune systems.
Autoimmunity: Aging can make it more likely for people to develop autoimmune diseases. This happens when the immune system gets confused and starts attacking the body's own tissues. This can lead to illnesses like rheumatoid arthritis or lupus.
Infection Susceptibility: Because their immune systems are weaker, older adults are more likely to get infections. This means they may end up in the hospital more often and have a higher risk of serious infections like pneumonia and urinary tract infections.
In short, getting older changes how our immune system works, which can affect our health a lot. This shows us how important it is to find ways to manage health problems related to aging.
