Aging And Your Immune System

As you get older, it may seem like you get sicker more than when you were younger. It may even take longer for you to recover. The reason is simple. Your body’s immune system gets weaker as you age.

Your immune system is made up of cells, tissues, and organs that defend your body against infection. Together, they defend your body against things that can cause infection, like bacteria and viruses. You are also more susceptible to other invaders like cancer cells, worms and rejection of transplanted organs and tissue.

As you age, your fewer immune cells don’t communicate as well with each other. This results in your body reacting longer to harmful germs. This is why older adults are more vulnerable to pneumonia, influenza, infective endocarditis and tetanus. The immunity system weakens at a different rate for everyone so it’s important to visit your physician on a regular basis.
