What are some common physical symptoms of anxiety?

Muscle tension, headaches, fatigue, and gastrointestinal disturbances are indeed common physical symptoms of anxiety. When individuals experience anxiety, the body's stress response may lead to the tightening of muscles, resulting in muscle tension. This can create discomfort and may lead to headaches. Additionally, the body's fight or flight mechanism can disrupt normal digestive functioning, leading to gastrointestinal disturbances, such as nausea or an upset stomach. Fatigue is also frequently reported, as the body is under constant stress, which can be physically exhausting over time.

In contrast, the other options do not accurately represent the typical manifestation of physical symptoms in individuals experiencing anxiety. Increased energy and alertness, for instance, may be associated with positive stress responses but are not generally aligned with anxiety, which often involves feelings of tension and overwhelming stress rather than heightened energy. Improved focus and productivity can occur in certain situations, but this is not a universal symptom of anxiety; rather, anxiety often disrupts focus and can impede productivity due to intrusive thoughts and physical discomfort. Lastly, it's inaccurate to suggest that no physical symptoms manifest, as anxiety is well-documented to influence physical health in various ways.
