Short of Breath? Normal Respiratory Rate & Medically Approved Next Steps

Feeling short of breath can be uncomfortable—and sometimes scary. But not every change in breathing means something serious is happening. Understanding your normal respiratory rate is one of the simplest and most medically reliable ways to know whether your breathing is within a healthy range.

Below, you'll learn what a normal respiratory rate looks like, what can affect it, and when it's time to take action.

What Is a Normal Respiratory Rate?

Your respiratory rate is the number of breaths you take per minute. One breath equals one inhale and one exhale.

Normal Respiratory Rate by Age

According to established medical guidelines:

• Adults (18+ years): 12–20 breaths per minute
• Adolescents (12–17 years): 12–20 breaths per minute
• School-age children (6–12 years): 18–30 breaths per minute
• Preschool children (3–5 years): 22–34 breaths per minute
• Toddlers (1–2 years): 24–40 breaths per minute
• Infants (under 1 year): 30–60 breaths per minute

For most healthy adults at rest, a normal respiratory rate falls between 12 and 20 breaths per minute.

How to Measure Your Respiratory Rate at Home

Checking your breathing rate is simple:

1. Sit or lie down and relax.
2. Set a timer for 60 seconds.
3. Count each full breath (one inhale + one exhale).
4. Avoid talking or moving while counting.

For the most accurate reading:

• Measure while you're resting.
• Avoid checking immediately after exercise or stress.
• Repeat if the number seems unusual.

If your rate consistently falls outside the normal respiratory rate range while resting, it's worth paying attention.

What Causes Shortness of Breath?

Shortness of breath (also called dyspnea) can have many causes. Some are mild and temporary. Others need medical care.

Common, Less Serious Causes

• Physical activity
• Anxiety or panic
• Mild respiratory infections (like a cold)
• Allergies
• Being out of shape
• Temporary exposure to smoke or pollution

These usually improve with rest or simple treatment.

Medical Conditions That May Affect Respiratory Rate

• Asthma
• Chronic obstructive pulmonary disease (COPD)
• Pneumonia
• Heart disease
• Anemia
• Blood clots in the lungs (pulmonary embolism)
• Severe allergic reactions

Some of these conditions can increase your respiratory rate above the normal respiratory rate range as your body tries to get more oxygen.

When Is a Respiratory Rate Too High or Too Low?

Fast Breathing (Tachypnea)

In adults, a resting respiratory rate above 20 breaths per minute may be considered elevated.

Possible reasons include:

• Fever
• Infection
• Lung disease
• Anxiety
• Heart problems

If fast breathing comes with chest pain, confusion, bluish lips, or severe shortness of breath, seek urgent medical care.

Slow Breathing (Bradypnea)

A respiratory rate below 12 breaths per minute in adults can be concerning, especially if accompanied by:

• Drowsiness
• Confusion
• Fainting
• Weakness

Slow breathing may be linked to medication side effects, head injury, or serious medical conditions.

Other Signs That Matter

Your normal respiratory rate is important—but it's not the only factor.

Seek medical attention right away if shortness of breath is accompanied by:

• Chest pain or pressure
• Bluish lips or fingertips
• Severe wheezing
• High fever
• Sudden confusion
• Fainting
• Swelling in the face or throat

These symptoms can signal potentially life-threatening conditions. Do not delay care.

What About Wheezing?

Wheezing is a high-pitched whistling sound when you breathe. It often suggests narrowed airways and may occur with:

• Asthma
• Allergic reactions
• Bronchitis
• COPD

If you're experiencing this symptom alongside shortness of breath, you can use a free AI-powered symptom checker for wheezing to help identify possible causes and understand whether you should seek medical attention.

Online tools are not a replacement for medical care, but they can help you decide whether you need to speak to a doctor.

Medically Approved Next Steps If You Feel Short of Breath

If your breathing feels off but you're not in immediate danger, here are practical steps you can take:

1. Pause and Rest

• Sit upright.
• Loosen tight clothing.
• Take slow, controlled breaths.

2. Try Pursed-Lip Breathing

This technique can help regulate your respiratory rate:

• Inhale slowly through your nose for 2 counts.
• Purse your lips.
• Exhale slowly for 4 counts.

This method can be helpful for anxiety-related breathlessness and certain lung conditions.

3. Check Your Respiratory Rate

Measure your breathing rate at rest.

• Is it within the normal respiratory rate range?
• Has it stayed elevated for several minutes?

Persistent abnormal readings deserve medical attention.

4. Review Recent Triggers

Ask yourself:

• Have I been sick?
• Was I exposed to smoke or allergens?
• Did I start a new medication?
• Was I anxious or stressed?

Identifying a trigger can help determine next steps.

5. Contact a Healthcare Professional

You should speak to a doctor if:

• Shortness of breath is new or worsening
• Your normal respiratory rate has changed significantly
• Symptoms interfere with daily activities
• You have a history of heart or lung disease
• You feel unsure about your symptoms

Even if symptoms seem mild, discussing them with a healthcare provider can offer reassurance and proper treatment if needed.

---

Can Anxiety Affect Respiratory Rate?

Yes. Anxiety can temporarily increase your respiratory rate. You may notice:

• Rapid breathing
• Chest tightness
• Lightheadedness
• Tingling in fingers

In anxiety-related cases, your breathing rate usually returns to a normal respiratory rate once you calm down.

However, do not assume anxiety is the cause without proper evaluation—especially if symptoms are new or severe.

How to Keep Your Respiratory System Healthy

Maintaining a normal respiratory rate over time depends on overall lung and heart health.

Practical Prevention Tips

• Avoid smoking and secondhand smoke.
• Stay physically active.
• Keep vaccinations up to date (like flu and pneumonia when appropriate).
• Manage allergies.
• Maintain a healthy weight.
• Follow treatment plans for asthma or COPD if diagnosed.

Small daily habits can make a meaningful difference.

When to Seek Emergency Care

Call emergency services immediately if you experience:

• Sudden, severe shortness of breath
• Chest pain spreading to the arm, jaw, or back
• Signs of a severe allergic reaction
• Blue or gray lips
• Loss of consciousness

These symptoms may signal heart attack, severe asthma attack, pulmonary embolism, or other life-threatening conditions.

Do not try to manage these symptoms alone.

The Bottom Line

Your normal respiratory rate is a simple but powerful health indicator. For most adults, that means 12–20 breaths per minute at rest.

Shortness of breath doesn't always mean something serious—but it should never be ignored if:

• It's new
• It's worsening
• It's accompanied by concerning symptoms
• Your respiratory rate is persistently outside normal range

If you're unsure, speak to a doctor. It's always better to ask questions early than to wait.

Your breathing is essential. Paying attention to your normal respiratory rate is one of the easiest ways to protect your health—and take action when needed.
