What is one consequence of chronic stress on health?

Chronic stress has been extensively studied for its negative impacts on health, particularly its strong correlation with an increased risk of heart disease. When an individual experiences prolonged stress, the body remains in a heightened state of alert, which can lead to various physiological changes, including elevated blood pressure and unhealthy levels of stress hormones such as cortisol. Over time, these factors can damage blood vessels, increase heart rate, and elevate cholesterol levels, which can contribute to the development of conditions like hypertension and heart disease.

In contrast, the other options describe outcomes that are generally not associated with chronic stress. For instance, increased energy levels and decreased muscle tension are typically experienced when an individual is in relaxed states, not during periods of prolonged stress. Similarly, improved immune function is contrary to the evidence, as chronic stress is known to compromise the immune system, making individuals more susceptible to illness. Thus, the connection between chronic stress and heart disease highlights the critical health consequences that can arise from sustained stress in one’s life.
