As a health professional, I can confirm that stress can indeed have a significant impact on your overall health, including your susceptibility to illness. When you're stressed, your body releases stress hormones like cortisol, which can suppress the immune system. A weakened immune system is less effective at fighting off infections and illnesses, making you more prone to getting sick. Stress can manifest in physical symptoms such as headaches, muscle tension, and fatigue, which can also lower your resistance to disease. Additionally, stress can lead to behaviors that increase the risk of illness, such as poor sleep, unhealthy eating, and a lack of exercise, all of which can further compromise your immune system.
