What is the diaphragm?

The diaphragm is the most efficient muscle for breathing. It’s a large, dome-shaped muscle located at the base of your lungs. Your abdominal muscles help move the diaphragm and give you more power to empty your lungs.

What is diaphragmatic breathing?

Diaphragmatic breathing helps you use your diaphragm correctly while breathing to:

• Strengthen the diaphragm.
• Decrease the work of breathing by slowing your breathing rate.
• Decrease oxygen demand.
• Use less effort and energy to breathe.

During diaphragmatic breathing, you consciously use your diaphragm to take deep breaths. When you breathe normally, you don’t use your lungs to their full capacity. Diaphragmatic breathing allows you to use your lungs at 100% capacity to increase lung efficiency.

What are other names for diaphragmatic breathing?

Diaphragmatic breathing is also known as:

• Abdominal breathing.
• Belly breathing.

Do certain conditions make it harder for me to use my diaphragm?

Conditions like chronic obstructive pulmonary disease (COPD) may prevent the diaphragm from working effectively.

Your lungs rise and fall naturally, but when you have COPD, air often becomes trapped in your lungs. This pushes down on your diaphragm. Your neck and chest muscles must then assume an increased share of the work of breathing. Conditions like COPD can leave your diaphragm weakened and flattened, causing it to work less efficiently.

What are the benefits of diaphragmatic breathing?

Diaphragmatic breathing offers several benefits to your body including:

• Helping you relax.
• Improving muscle function during exercises and preventing strain.
• Increasing how much oxygen is in your blood.
• Making it easier for your body to release gas waste from your lungs.
• Reducing blood pressure.
• Reducing heart rate.

What conditions does diaphragmatic breathing help improve?

Diaphragmatic breathing can help several conditions that cause symptoms that affect how you breathe including:

• Anxiety.
• Asthma.
• COPD.
• Stress.

Diaphragmatic breathing can help treat certain conditions, but it shouldn’t be the only treatment. You can use this technique along with other treatments recommended by your healthcare provider.

How do I do diaphragmatic breathing exercises?

When you first learn the diaphragmatic breathing technique, it may be easier for you to follow the instructions lying down.

1. Lie on your back on a flat surface or in bed, with your knees bent and your head supported. You can use a pillow under your knees to support your legs.
2. Place one hand on your upper chest and the other just below your rib cage. This will allow you to feel your diaphragm move as you breathe.
3. Breathe in slowly through your nose so that your stomach moves out, causing your hand to rise. The hand on your chest should remain as still as possible.
4. Tighten your stomach muscles, so that your stomach moves in, causing your hand to lower as you exhale through pursed lips (see "Pursed Lip Breathing Technique"). The hand on your upper chest should remain as still as possible.

Diaphragmatic breathing technique (sitting)

As you gain more practice, you can try the diaphragmatic breathing technique while sitting in a chair.

To perform this exercise while sitting in a chair:

1. Sit comfortably, with your knees bent and your shoulders, head and neck relaxed.
2. Place one hand on your upper chest and the other just below your rib cage. This will allow you to feel your diaphragm move as you breathe.
3. Breathe in slowly through your nose so that your stomach moves out against your hand. The hand on your chest should remain as still as possible.
4. Tighten your stomach muscles, so that your stomach moves back in, as you exhale through pursed lips. The hand on your upper chest must remain as still as possible.

Do I need to practice diaphragmatic breathing?

Yes, practicing diaphragmatic breathing makes it easier. You may notice it takes an increased effort to use your diaphragm correctly. At first, you'll probably get tired while doing this exercise. But keep at it, because with continued practice diaphragmatic breathing will become automatic.

How often should I practice diaphragmatic breathing exercises?

At first, practice this exercise for five to 10 minutes about three to four times per day. Gradually increase the amount of time you spend doing this exercise, and perhaps even increase the effort of the exercise by placing a book on your abdomen.

What is Lorem Ipsum?

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

Why do we use it?

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).

Where does it come from?

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.

The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form, accompanied by English versions from the 1914 translation by H. Rackham.

Where can I get some?

There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some form, by injected humour, or randomised words which don't look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn't anything embarrassing hidden in the middle of text. All the Lorem Ipsum generators on the Internet tend to repeat predefined chunks as necessary, making this the first true generator on the Internet. It uses a dictionary of over 200 Latin words, combined with a handful of model sentence structures, to generate Lorem Ipsum which looks reasonable. The generated Lorem Ipsum is therefore always free from repetition, injected humour, or non-characteristic words etc.
