Your immune system is your body's natural defense against viruses, bacteria, and other harmful substances. It is made up of a complex network of cells, tissues, and organs that work together to recognize threats, fight infections, and support healing.

A healthy immune system depends on many factors working together. Learning how your immune system connects with your sleep, nutrition, digestive system, stress levels, physical activity, and overall health can help you better understand lifelong immune wellness.

Immune health is influenced by many everyday factors, including nutrition, quality sleep, physical activity, stress management, hydration, age, chronic health conditions, medications, vaccinations, and overall lifestyle habits. These factors can affect your body's ability to respond to illness and recover from infection.

Your immune system works closely with every body system. Healthy daily habits often support multiple aspects of wellness, helping your body respond to illness, recover from infection, and maintain overall health.
