Anxiety is not only a feeling of worry. It also shows up in the body. Common physical signs include a racing or pounding heart, rapid breathing, dizziness, shortness of breath, and headaches. These sensations are real, and they can be frightening, but they usually come from your body’s stress response rather than from a dangerous medical problem. If they are frequent, intense, or disrupting your life, anxiety may have become a disorder that responds well to treatment.
Why anxiety affects the body
When your brain senses a threat, it triggers the fight-or-flight response. Your heart speeds up, your breathing gets faster, and your muscles tense so you are ready to act. In anxiety disorders this alarm goes off when there is no real danger, or stays on for too long.
Common physical signs of anxiety
- Racing or pounding heart
- Rapid breathing or shortness of breath
- Dizziness or lightheadedness
- Headaches
- Sweating, trembling, or shaking
- Muscle tension, especially in the neck, shoulders, and jaw
- Nausea or stomach discomfort
- Trouble sleeping
When anxiety may be more than everyday stress
Some anxiety is a normal part of life. It may signal an anxiety disorder when it happens without a clear reason, shows up more often or more intensely than you would expect, or becomes overwhelming and disrupts work, school, sleep, or relationships. Panic attacks, which are sudden waves of intense fear with strong physical symptoms, are one example. You can read more about the difference in our post on stress vs. anxiety.
Should I see a doctor first?
It is a good idea. Chest pain, a fast heartbeat, or dizziness can have medical causes, so a check-up can rule those out. If you have new, severe, or unusual symptoms, such as chest pain with shortness of breath, seek medical care right away. Once medical causes are ruled out, a therapist can help you with the anxiety itself.
What helps
Treatment for anxiety can include psychotherapy such as cognitive behavioral therapy (CBT) and exposure therapy, medication when appropriate, and supportive habits like regular exercise, relaxation techniques, limiting caffeine and alcohol, good sleep, and strong social connection. At Footprints, our bilingual therapists provide anxiety and panic disorder therapy in English and Spanish, in person and by telehealth. Anxiety and low mood often travel together, so we also offer depression therapy.
