What is Immune System?

We are surrounded by millions of bacteria, viruses and other microbes (germs) that have the potential to enter our bodies and cause harm. The immune system is the body’s defence against pathogens (disease-causing microbes).

The immune system is made up of non-specialised defences such as skin and the acidic juice produced by your stomach. But it also has some highly specialised defences which give you immunity against (resistance to) particular pathogens. These defences are special white blood cells called lymphocytes. Other types of white blood cells play an important part in defending your body against infection.

The body’s defense system is only as dependable as the support it gets. Some people are just blessed with a good set of genes that ensure a strong immune system. For others who are not as lucky, they must learn how to improve immunity by observing proper nutrition, sufficient rest, a healthy active lifestyle, plenty of sun and reduced stress.
