Physical symptoms of anxiety may include increased heart rate, sweating, trembling, and headaches. Individuals may also experience gastrointestinal issues such as nausea or diarrhea, muscle tension, and fatigue. Some may have difficulties concentrating or sleep disturbances. These physical reactions occur as part of the body’s fight-or-flight response, triggered by perceived threats or stressors. Additionally, people may feel increased irritability or restlessness. Recognizing these symptoms is crucial for managing anxiety effectively and seeking appropriate support or treatment.
