Which term is defined as a physical, chemical, or emotional factor that causes bodily or mental tension and may contribute to disease causation?

• A. Stress
• B. Fatigue
• C. Anxiety
• D. Pressure

Answer: (A)

Stress is the term that fits this definition. It refers to any physical, chemical, or emotional factor that triggers bodily or mental tension and can contribute to disease causation. This broad idea includes physical conditions like illness, chemical factors such as toxins or drugs, and emotional states like fear or anger. The body’s response to stress involves activating the fight-or-flight system and the HPA axis, releasing hormones that increase heart rate, muscle tension, and alertness. While brief stress can be adaptive, chronic or excessive stress can lead to health problems, including cardiovascular issues, weakened immune function, and mental health effects. The other options describe specific experiences or states (fatigue as tiredness, anxiety as worry, pressure as external demand) and do not capture the broad factor that causes tension and potential disease.
