When is the diaphragm relaxed




















Keep the tension for seconds and then relax the muscles and take a light inhalation. Can you breathe for minutes using the tummy or stomach only? After the student is able to breathe using mainly the diaphragm, the next step is to learn how to relax it during exhalations.

Each exhale should be accompanied by the relaxation of all bodily muscles. The changes in the breathing pattern for a person with the low initial CP, who practices relaxation of the diaphragm only no deliberate air hunger , are shown below. Your breathing before this exercise is shown using the black line with forceful exhalations. During this exercise, you should unblock the diaphragm. You have the following goal: take your usual inhalation using your diaphragm only and then relax your diaphragm for exhalation.

This will make your exhalations smooth the blue line for your new breathing pattern. Note that the depth of your inhalations remains the same, but the frequency of your breathing becomes smaller. Hence, reduced breathing for low CP students is achieved using relaxation only. If you do this exercise correctly, you should notice that your pulse or heart rate is lower after the session. For most people, this is a transitory temporary exercise.

Heart and hypertension patients should stick with this exercise until they get over 20 s CP and reduce or lower their high blood pressure to normal levels without medication. Practice this exercise for minutes so that you get a clear sensation of your relaxed diaphragmatic exhalation. You can or even should wear the belt during this exercise if you are not sure about your ability to breathe using your diaphragm only. The belt will prevent you from having any chest breathing.

Its use is described in Module 8. With every inhalation, your diaphragm flattens, pulling down on the metaphorical umbrella handle , which expands your ribcage and reduces pressure in your chest to pull air into your lungs. Now when you exhale, imagine the umbrella top pushing upward and forming the dome shape underneath your ribs. Can you feel that each exhale is guided by the diaphragm pushing back up into your chest?

Thankfully, we have brainstem neurons and phrenic nerves instead of mischievous goblins, which control the movement of the diaphragm with cyclical precision. When you breathe, you may also feel that your upper body expands. Although the diaphragm is the main force behind respiration, the muscles that fill the gaps between your ribs are also important.

These thin ribcage muscles are called intercostal muscles. Place a finger between a pair of your ribs and take a few big breaths. You should be able to feel these muscles lengthen with each inhale, allowing your ribs to expand and shorten with each exhale, decreasing the volume of your chest cavity.

The ability of your intercostals to expand and collapse your ribcage allows you to take bigger breaths. This function is especially important when you are active and in need of more oxygen. During exercise and other strenuous activities, the human body requires more energy and therefore more oxygen.

The intercostal muscles provide structure and flexibility to your upper body and when you breathe, they allow your ribcage to expand and contract. Athletes and people running away from zombies depend on both the diaphragm and the intercostal muscles to allow for deep breaths that provide hard-working cells with oxygen.

Diaphragm injuries are most often caused by traumatic physical events such as traffic accidents. Considering that the umbrella muscle is essential for breathing, injuries to the diaphragm results in life-threatening scenarios that require serious medical care.
