Introduction
A strong immune system is essential for protecting the body against infections, viruses, and diseases. While no single food or supplement can guarantee immunity from illness, adopting healthy lifestyle habits can significantly strengthen your body’s natural defense system.
This guide explores proven ways to boost your immune system naturally and maintain better overall health throughout the year.
What Is the Immune System?
The immune system is a complex network of cells, tissues, and organs that work together to defend the body against harmful pathogens such as bacteria, viruses, fungi, and parasites.
When functioning properly, the immune system identifies and destroys threats before they can cause illness.
