Which of the following is NOT a health impact of stress?

Improved immune response is the correct choice because stress typically leads to a range of negative health impacts rather than beneficial effects. Chronic stress is known to weaken the immune system, making individuals more susceptible to infections and illnesses. High blood pressure is a common consequence of stress due to the body’s release of hormones that encourage the heart to beat faster and constrict blood vessels. Anxiety attacks can also occur as a direct result of stress, as the body reacts to perceived threats with heightened arousal and anxiety. Chronic pain is frequently associated with long-term stress, leading to tension in muscles and increased sensitivity to pain. Therefore, while other options highlight detrimental effects of stress, improved immune response represents a deviation from this pattern, affirming it as the correct answer.
