The strength of Immune is undeniable. This amazing internal army composed of trillions of cells works around the clock to keep us healthy.
The strength of our immune system determines our body's ability to resist infection and stop the growth of abnormal or cancerous cells. Colds, flus, fatigue, bacteria, viruses, cancer, and hepatitis all reflect a weakened immune system. In some serious cases, the strength of the immune system can mean the difference between life and death.
Importance of Immune System
The importance of the immune system is underlined by the example of people who have been born with problems with their immune system – a condition called 'immunodeficiency'. Such individuals can become infected extremely easily, and the results can be fatal – this can mean living in a sterile environment, with only limited contact with people.
A good indicator of the level of our immune system is how energized or alive we feel. When we feel weak we usually use such expressions as being below par, feeling low, or being under the weather.
Understanding the Immune System
More positively, understanding how the immune system works has allowed us to develop amazing life saving operations to safely transplant organs such as kidneys, hearts, lungs and livers. Also, immune research into important diseases such as rheumatoid arthritis, type 1 diabetes, asthma/allergy and cancer, as well as infectious diseases such as HIV/AIDS and tuberculosis, is uncovering important knowledge about how these diseases develop, and new vaccines and therapies are becoming available as a result.
