Do you seem to catch cold after cold, while your friends sail through winter unscathed? Maybe you need to think about strengthening your immune system.
You may pay more attention to the health of your immune system during the winter, when colds and flu surround you. But the truth is, your immune system has to work hard all through the year, whether it’s offering protection from a flu virus or an infection that could happen any time.
“We are endowed with a great immune system that has been designed evolutionarily to keep us healthy,” says Bruce Polsky, MD, interim chairman department of medicine and chief division of infectious disease at St. Luke’s-Roosevelt Hospital Center in New York City.
How the Immune System Works
The immune system is your body’s natural defense system. It’s an intricate network of cells, tissues, and organs that band together to defend your body against invaders. Those invaders can include bacteria, viruses, parasites, even a fungus, all with the potential to make us sick. They are everywhere – in our homes, offices, and backyards. A healthy immune system protects us by first creating a barrier that stops those invaders, or antigens, from entering the body. And if one slips by the barrier, the immune system produces white blood cells, and other chemicals and proteins that attack and destroy these foreign substances. They try to find the antigen and get rid of it before it can reproduce. Failing that, the immune system revs up even more to destroy the invaders as they multiply.
The immune system can recognize millions of different antigens. And it can produce what it needs to eradicate nearly all of them. When it’s working properly, this elaborate defense system can keep health problems ranging from cancer to the common cold at bay.
Answer:
The immune system protects us from disease caused by bacteria, viruses and toxins, and helps remove foreign bodies and malignant cells from our system. In addition, the immune system is responsible for down-regulating immune responses against external harmless triggers such as food, or against the bodies' own tissue.A strong immune system is one of the biggest advantages for humans and there are many steps individuals can take to help strengthen their immune systems to help fight infections and reduce the risk of contracting highly contagious diseases.Immunology is the study of the immune system and is a very important branch of the medical and biological sciences. The immune system protects us from infection through various lines of defence. If the immune system is not functioning as it should, it can result in disease, such as autoimmunity, allergy and cancer.Vitamin C is one of the biggest immune system boosters of all. In fact, a lack of vitamin C can even make you more prone to getting sick. Foods rich in vitamin C include oranges, grapefruits, tangerines, strawberries, bell peppers, spinach, kale and broccoli
