🛡 Understanding the Immune System Function
The immune system is a sophisticated network of organs, tissues, and cells working together to defend the body against harmful invaders. White blood cells play a key role by identifying and neutralizing pathogens.
To boost immune system function, individuals should:
-
Incorporate immune-boosting foods like citrus fruits, leafy greens, and nuts.
-
Consume natural immune boosters such as garlic, ginger, and turmeric.
-
Support gut health with probiotics to maintain a balanced microbiome.
-
Manage stress levels, as chronic stress weakens the immune system.
-
Get adequate sleep to allow the body to repair and regenerate immune cells.
✅ Key Takeaway: A holistic approach combining nutrition, lifestyle, and supplementation is essential for strong immunity.
