"Both too much and too little are bad while somewhere in the middle is just right. Scientists commonly refer to this statistical phenomenon as a “J-shaped” curve. Research has shown exercise can influence the body’s immune system. Exercise immunity refers to both the systemic (whole body cellular response) and mucosal (mucous lining of the respiratory tract) response to an infectious agent, which follows this J-shaped curve."
