What physical symptoms can indicate stress?

Muscle tension and headaches are well-documented physical symptoms of stress. When a person experiences stress, their body initiates a fight-or-flight response that can lead to various physiological changes. Muscle tension is a common reaction to stress, as the body tightens muscles in preparation for potential physical challenges. This tension can lead to discomfort and ultimately cause headaches, particularly tension-type headaches, which are often linked to sustained muscle contraction and stress.

In contrast to this correct answer, increased appetite may occur in some individuals who cope with stress through eating, but it is not a universal symptom of stress. Heightened calmness and improved concentration generally reflect positive states of functioning, often contrary to stressful experiences. Therefore, muscle tension and headaches uniquely encapsulate the typical physiological responses associated with stress.
