Common Physical Symptoms of Anxiety
Anxiety is often experienced not just as emotional distress, but also through a range of physical symptoms. The most frequently reported physical symptoms include restlessness, feeling keyed up or on edge, being easily fatigued, difficulty concentrating, irritability, muscle tension, and sleep disturbances such as trouble falling or staying asleep 13. In both adults and children, additional somatic complaints like headaches, stomachaches, drowsiness, and sleeplessness are common, especially among those with anxiety disorders such as generalized anxiety disorder, separation anxiety disorder, and social phobia .
Physical Symptoms in Youth and Adults
Physical symptoms of anxiety can appear across all age groups. In youth, the number and severity of physical symptoms are linked to age, the type of anxiety disorder, and the presence of other internalizing disorders. These symptoms tend to decrease with effective treatment, regardless of whether the treatment is medication, cognitive-behavioral therapy, or a combination . In adults, physical symptoms such as muscle tension, fatigue, and sleep problems are key features of generalized anxiety disorder and are used to assess the severity of anxiety .
Anxiety, Physical Illness, and Somatic Syndromes
Anxiety is closely associated with medically unexplained physical symptoms and functional somatic syndromes like irritable bowel syndrome, fibromyalgia, and chronic fatigue syndrome. People with these conditions often report higher levels of anxiety and depression compared to healthy individuals or those with medical illnesses of known cause . Furthermore, anxiety and depression are as strong or even stronger predictors of future physical health problems and somatic symptoms as traditional risk factors like obesity and smoking .
Recurrence and Reporting of Physical Symptoms
The presence of multiple physical symptoms increases the risk of recurrence for both anxiety and depressive disorders, even when accounting for mood and anxiety symptom severity . Anxiety tends to be linked to the reporting of physical symptoms in the moment, while depression is more associated with recalling physical symptoms over time . This distinction is important for understanding how people experience and report their symptoms.
Biological and Psychological Factors
Anxiety’s physical symptoms may be related to changes in the central nervous system, such as low serotonin activity and increased noradrenergic activity . There is also evidence of a link between anxiety and inflammatory markers in the blood, such as elevated white blood cell counts . Psychological factors, including negative metacognitive beliefs about worry and uncontrollability, are also strongly associated with anxiety symptoms in people with chronic physical illnesses .
Physical Activity and Symptom Reduction
Engaging in physical activity, including both aerobic and resistance exercise, has been shown to reduce anxiety symptoms and improve overall psychological well-being . In college students, higher levels of physical activity are linked to fewer social anxiety symptoms, better sleep, and greater psychological resilience . These findings suggest that lifestyle interventions can play a role in managing the physical symptoms of anxiety.
Conclusion
Anxiety is commonly accompanied by a range of physical symptoms, including muscle tension, fatigue, headaches, stomachaches, and sleep disturbances. These symptoms are present in both youth and adults and are closely linked to the severity and recurrence of anxiety disorders. Biological, psychological, and lifestyle factors all contribute to the experience of physical symptoms in anxiety. Recognizing and addressing these symptoms is important for effective treatment and overall health.
