Anxiety and Physical Symptoms: What's Happening in Your Body
By Kathie Bolles, PMHNP-BC
Anxiety is not only a mental experience; it also produces real physical symptoms. The NIMH lists physical signs of generalized anxiety such as restlessness, feeling wound-up or on edge, muscle tension, fatigue, and difficulty sleeping, and the APA describes anxiety as involving somatic tension, with a racing heart, faster breathing, and tense muscles. These reactions reflect the body's stress response rather than something being wrong with your body, but they can be distressing, and talking with a clinician can help you understand what is going on.
Why does anxiety cause physical symptoms?
Anxiety activates the body's stress response, sometimes called the fight-or-flight system. The APA notes that when the body mobilizes to meet a perceived threat, muscles tense, breathing quickens, and the heart beats faster.
This response is protective in real danger, but when it fires regularly in everyday situations, it produces the uncomfortable physical sensations people associate with anxiety.
What are the most common physical symptoms of anxiety?
Common symptoms include muscle tension, especially in the neck, shoulders, and jaw; restlessness or feeling on edge; fatigue; difficulty concentrating; irritability; and trouble falling or staying asleep, which the NIMH lists among symptoms of generalized anxiety disorder.
People also often describe a racing or pounding heart, chest tightness, faster breathing, sweating, stomach upset or nausea, headaches, and dizziness. Panic attacks can involve a sudden, intense wave of several of these sensations; see more on panic attacks and panic disorder.
How can you tell whether a symptom is anxiety or a medical condition?
Some physical symptoms of anxiety overlap with genuine medical conditions, including heart, lung, and thyroid conditions. That overlap is why chest pain, severe shortness of breath, or other concerning symptoms always deserve a medical evaluation to rule out physical causes, in addition to any mental health assessment.
A helpful approach is not to choose one explanation in your head, but to let a medical clinician rule out physical causes while a mental health clinician assesses anxiety. The two can also coexist, and both matter.
What helps with anxiety-related physical symptoms?
Treatment typically combines approaches: psychotherapy to understand and change the patterns that keep anxiety going, and, where clinically appropriate, medication management to reduce symptoms. Skills like paced breathing and regulating sleep and caffeine can also be part of a practical plan, and a clinician can help you build one that fits.
It is also worth noting what does not help: avoiding every situation that triggers symptoms tends to reinforce anxiety over time. A clinician can help you approach this gradually and safely. See how psychotherapy and medication work together.
How does Mynd Works approach anxiety care?
Care begins with an evaluation to understand your symptoms, your medical context, and what has been tried before. The anxiety care page describes the conditions Mynd Works helps address and what an evaluation involves.
If anxiety is part of the picture, your clinician builds an individualized plan, in person in Austin or by telehealth, and coordinates with your broader care so physical and mental health are both considered. Learn more about when to seek help for anxiety or request a consultation.
Common questions
Can anxiety cause chest pain?
Anxiety can cause chest tightness, pressure, or a racing heart, especially during panic. Chest pain always deserves prompt medical evaluation to rule out cardiac causes, and that evaluation can itself bring clarity and relief.
Can anxiety make you feel dizzy or lightheaded?
Yes. Faster breathing and muscle tension during anxiety can produce dizziness or lightheadedness. Because dizziness can also have medical causes, it is reasonable to have it checked, especially if it is new or severe.
When should you see a doctor for anxiety symptoms?
Consider an evaluation when symptoms are frequent, interfere with work, school, or relationships, or simply keep you from feeling like yourself. If symptoms are severe or you are unsure of the cause, start with a medical check and then a mental health evaluation.
Does Mynd Works treat anxiety in Austin?
Yes. Anxiety is one of the areas of care Mynd Works evaluates and treats, in person in Austin and by secure telehealth where clinically appropriate. You can request a consultation to discuss your situation.
