Which of the following is a common physical response to extreme anxiety?

Trembling or shaking is a well-documented physical manifestation of extreme anxiety. When an individual experiences high levels of anxiety, the body enters a heightened state of arousal due to the activation of the sympathetic nervous system, often referred to as the "fight or flight" response. This physiological response can lead to various symptoms, including tremors or shakes as muscles tense up and energy levels rise in preparation for a perceived threat.

Understanding the nature of anxiety responses helps emphasize that they typically involve heightened physiological reactions rather than comforting behaviors such as increased appetite or excessive sleeping. In fact, many people may experience a decrease in appetite when they are anxious. Similarly, concentration improvement is not typically associated with anxiety; rather, anxiety often impairs concentration and cognitive function.

Recognizing tremors or shaking as a common physical response allows individuals to better understand their symptoms and seek appropriate support or intervention when facing anxiety-related challenges.
