Final answer:
Applying stress at deeper levels can have negative effects on physical and mental health, including psychological disorders and physical illnesses.
Step-by-step explanation:
When stress is applied at deeper levels, it can have negative consequences on both physical and mental health. Excessive or chronic stress can contribute to the development of psychological disorders such as post-traumatic stress disorder and major depressive disorder. It can also lead to the progression of physical illnesses and diseases, including heart disease and impaired immune response.
Furthermore, long-term stress can have negative effects on the body, such as suppressing the immune system, causing fatigue, and impairing wound healing. It can also cause symptoms of depression and increase the risk of heart attacks.
In conclusion, while stress in moderate levels can be beneficial for performance, excessive or chronic stress can have serious detrimental effects on both physical and mental well-being.
