aging immune system vs Covid 19

The immune system is the body’s natural defense network, made up of cells, tissues, and organs that work together to protect against harmful pathogens like bacteria, viruses, and toxins. A strong immune response helps maintain health, fight infections, and promote faster recovery. Key components include white blood cells, lymph nodes, antibodies, and the thymus, all playing vital roles in immunity. Supporting your immune system with proper nutrition, regular exercise, quality sleep, and stress management can significantly enhance resilience. Learn how the immune system functions, common disorders, and science-backed ways to naturally boost immunity for long-term health.
