What is natural immunity?

Natural immunity refers to the body's ability to protect itself against infections and diseases through mechanisms that are partially inherited and influenced by an individual's lifestyle and overall health. This type of immunity develops through exposure to pathogens in the environment, allowing the immune system to recognize and respond to specific invaders.

The concept encompasses both innate (natural) immunity, which we are born with, and adaptive immunity that develops after exposure. Therefore, factors such as genetics, nutrition, physical activity, and other elements of a healthy lifestyle contribute to the robustness of natural immunity.

By focusing on the interplay between inherited traits and lifestyle factors, this choice accurately reflects how our immune system is equipped to handle infections, distinguishing it from immunity gained solely through vaccinations or medical interventions.
