What Is Immune System Health?

Your immune system is your body’s defense mechanism. It protects you from viruses, bacteria, and harmful pathogens.

Think of it like a security system:

• It identifies threats
• Fights infections
• Remembers past invaders

A strong immune system means:
✔ Faster recovery
