Introduction
Your heart is racing. Your chest feels tight. You're exhausted, but you can't sleep. Your stomach is in knots.
These aren't just "in your head"-they're real physical symptoms of anxiety.
Anxiety affects your whole body. Understanding the physical symptoms can help you recognize anxiety and find relief.
This guide covers the common physical symptoms of anxiety and what you can do about them.
How Anxiety Causes Physical Symptoms
When you feel anxious, your body activates the "fight-or-flight" response:
- Heart rate increases
- Blood pressure rises
- Muscles tense
- Breathing changes
- Digestion slows
These physical changes create the symptoms you feel.

Why Symptoms Occur
Fight-or-Flight
Your body prepares to fight or run:
- Heart pumps faster to deliver blood
- Muscles tense for action
- Breathing quickens for oxygen
Hyperventilation
Shallow, rapid breathing changes blood chemistry:
- Causes dizziness
- Creates tingling
- Makes you feel like you can't breathe
Muscle Tension
Anxiety causes chronic muscle tension:
- Leads to headaches
- Creates body aches
- Causes jaw clenching
Digestive Changes
Fight-or-flight slows digestion:
- Causes nausea
- Leads to stomach issues
- Affects appetite
Managing Physical Symptoms
1. Address the Anxiety
The best way to reduce physical symptoms is to manage the underlying anxiety:
- Therapy (CBT)
- Medication if needed
- Lifestyle changes
- Relaxation techniques
2. Breathing Techniques
Slow, deep breathing counters hyperventilation:
- Breathe from belly, not chest
- Make exhale longer than inhale
- Box breathing (4-4-4-4)
3. Exercise
Regular exercise:
- Burns off stress hormones
- Releases tension
- Improves overall health
4. Progressive Muscle Relaxation
Tense and release each muscle group:
- Start at toes
- Work up through body
- Notice the difference
5. Stay Hydrated
Dehydration worsens symptoms:
- Drink enough water
- Limit caffeine
- Avoid alcohol
6. Get Checked
Some symptoms warrant medical attention:
- New or severe chest pain
- Shortness of breath with exertion
- Persistent headaches
- Any symptom that's new or concerning
When to See a Doctor
Consider medical evaluation if:
- Symptoms are new or severe
- You have chest pain
- Shortness of breath is significant
- You have other health conditions
- You're unsure of the cause
A doctor can rule out other conditions and help you manage anxiety.
