Which symptom describes a physical effect of chronic stress?

High blood pressure is a known physical effect of chronic stress. When the body experiences prolonged stress, it enters a heightened state of alertness where the heart beats faster, and blood vessels constrict. This response, often referred to as the "fight or flight" reaction, can lead to an increased workload on the heart and a rise in blood pressure. Over time, chronic high blood pressure can result in serious health issues, including heart disease, stroke, and kidney problems.

In contrast, heightened feelings of joy, enhanced memory, and greater focus on tasks typically represent positive effects or responses that are not associated with the physical toll of chronic stress. These options highlight aspects that improve mental clarity or emotional well-being rather than indicate physiological consequences of stress. Thus, high blood pressure stands out as a direct and significant physical symptom associated with the effects of chronic stress on the body.
