14 Surprising Ways Stress Is Silently Wrecking Your Body

2. Stress and the Immune System

Stress doesn't just affect the heart; it also has a significant impact on the immune system. The body's stress response involves the release of cortisol, which, while useful in short bursts, can suppress the immune system when present in high levels over long periods. This suppression makes the body more susceptible to infections and illnesses, as it reduces the efficacy of immune cells. Studies have shown that individuals under chronic stress are more likely to catch colds, experience longer recovery times, and have a higher susceptibility to diseases. This connection highlights the necessity of balancing stress to maintain a robust immune system capable of defending the body against pathogens.
