Step-by-step explanation:
Stress can lead to sickness through various steps. When you are stressed, your body diverts energy away from digestion, the immune system, and vital processes such as growth. This can result in symptoms such as upset stomach, headache, and increased susceptibility to illness. If stress continues over a long period of time, it can lead to the stage of exhaustion, where the body's ability to resist stress is depleted and illnesses can occur. Additionally, chronic stress can weaken the immune system, making individuals more prone to infections and diseases.
