Immunity: Ways You Can Maintain Or Improve Your Immunity(2023)


Immunity is necessary for survival. After all, we live in a biosphere comprising of viruses, bacteria, and various other pathogens ready to invade us, feed on us, and make us sick. Immunity is our defence—it is like a soldier protecting our borders.

What kind of immunity does the human body have?
There are three types of immunity in humans called innate, adaptive, and passive:

  • Innate immunity is the first line of defence against pathogens, our first protective layer i.e. the skin which is the external barrier of our body. If a pathogen manages to surpass this layer it has to face adaptive or acquired immunity.
  • Adaptive immunity is what we develop through life by developing antigens against any pathogen or when we get vaccinated.
  • Passive immunity is what we get from some external source like a baby gets it from its mother after breastfeeding.

How can you maintain a good level of immunity?
Researchers are studying various effects of lifestyle, diet, and exercises on immunity. Leading a good lifestyle is our first step to boost immunity. Here are some key points to remember:

  • Eat right and healthy. Don’t forget to include fruits and vegetables in your diet
  • Maintain a healthy weight
  • Develop a proper sleeping pattern—follow your biological clock
  • Quit smoking
  • Maintain good hygiene
  • Avoid alcohol completely or take it in moderation
  • Keep a positive approach to life
  • Stay physically active and exercise
