How To Strengthen Immune System




Human body is susceptible to infections on a daily basis. Infections from various microorganisms and germs including bacteria, viruses, parasites, toxins etc. can occur almost anywhere, in schools, at our offices, on the roads, in public transportation vehicles and so on.

Our body can get infected from the air we breathe, the water we drink, the food we eat, also the place we live in, and its surroundings. Infections can lead to various health ailments ranging from a simple headache or fever to dangerous diseases like cholera, which causes dehydration and can lead to death.

In order to deal with diseases and health ailments, we generally take medicines, which are prescribed by our doctor. Different people have different capacities and level of tolerances against various diseases. The reason for their different capacities to tolerate a health ailment is the difference in their immunity.


Immunity is our body’s natural defense system against invaders attacking the human body. It is a combination or a collection of different structures, series of operations, cells, tissues, and even organs, which work collectively.

How does an Immune System Work?

The immune system works for years and years within our body and protects us until our last breath. In fact, our bodies would not be able to survive the daily attacks of various harmful organisms without the immune system. The objective of the immune system is to fight against and protect the body from infections and attacks by various pathogens.

They attack these pathogens and hence prevent them from causing any harm to the human body. They protect the body from attacks of pathogens by killing the pathogens, eating them, coating them, and filtering the body liquids and hence remove the microbes and pathogens inside them. Major types of immune cells in the body include lymphocytes and dendritic cells. It is always said that health is wealth.

Weak health affects all spheres of our life, both personal, professional and the most important, our day-to-day life. Now that we know what a crucial role the immune system plays in our health, let us have a look at the causes of a weak immune system and how we can take efforts to increase our immune power naturally.
