The Role of Exercise in Immune Health

Exercise is crucial for immune health, impacting immune function in various positive ways. Discover the profound effects of exercise on bolstering the immune system. 

Introduction

The immune system defends against pathogens and promotes overall health. Exercise influences immune cells, antibodies, and cytokines to enhance defense mechanisms. 

1. Immune System Overview

Exercise triggers a temporary increase in immune cells, improving surveillance against viruses and bacteria immediately after physical activity. 

2. Immediate Effects of Exercise

Regular exercise contributes to long-term improvements in immune function by reducing inflammation and enhancing immune response efficiency. 

3. Chronic Effects of Exercise

Regular physical activity lowers levels of chronic inflammation markers, reducing the risk of inflammatory-related diseases and supporting immune function. 

4. Reducing Chronic Inflammation

Exercise enhances the body's response to vaccines by boosting antibody production, potentially improving vaccine effectiveness. 

5. Enhancing Vaccine Response
