Effects of Diaphragmatic Breathing[edit | edit source]

  1. Detoxifies and releases toxins:[1]
    • The human body is able to release 70% of its toxins through breathing. It is recommended that diaphragmatic breathing at least 3 times per day for 39 seconds can be beneficial.[1]
  2. Anti-stress:[1][2]
    • When someone experiences stress, their brain releases cortisol (i.e. the "stress hormone"). Cortisol causes an increase in heart rate and blood pressure.
    • Taking a few diaphragmatic breaths can lead to a reduction in heart rate. This allows more oxygen to enter the bloodstream which calms the brain down (i.e. reduces anxiety, improves circulation, enhances muscular relaxation etc).
    • Deep breathing can also lead to the release of endorphins, which elevates mood.
  3. Relaxation and mood elevation:[1][3]
    • Diaphragmatic breathing stimulates the vagus nerve which induces relaxation. NB 75% of vagal nerve fibres are parasympathetic.[1]
  4. Pain relief:[1][4]
    • Breathing into pain can result in improved circulation to that specific area, relieve tension and enhance oxygenation levels. This triggers the release of endorphins, which has a positive impact on pain levels.[4]
  5. Enhances the immune system:[1]
    • Deep breathing improves an individual's ability to metabolise nutrients and vitamins. It is also beneficial for digestion, which ultimately strengthens immunity.
  6. Reduces blood pressure:[4]
    • Relaxation leads to dilation of the blood, which improves circulation and decreases blood pressure. Deep breathing also helps to reduce / regulate heart rate, which has a positive impact on blood pressure.
  7. Improves cellular regeneration:[1]
    • Deep breathing helps our bodies to be better oxygenated and improves circulation, which enhances cellular regeneration.
  8. Enhances posture:[1][4]
    • Inspiration lengthens the spine, facilitates lumbopelvic movements, activates core muscles. It has also been shown that it may be associated with improvements in balance.[5]

Evidence Based Practice[edit | edit source]

  • Allison et al.[9] reported that diaphragmatic activity increases in healthy subjects during lumbopelvic motion control tests.
  • O’Sullivan and Beales[10] concluded in their case studies that lumbopelvic movements decrease in patients with diaphragmatic injuries.
  • Moreover, patients with chronic low back pain have often been reported to have defects in posture and motor control.[11][12]

Effect of Mechanical Ventilation on the Diaphragm[edit | edit source]

  • Ventilator-induced diaphragmatic dysfunction (VIDD):
    • VIDD is the loss of diaphragmatic force-generating capacity as a consequence to use of mechanical ventilation due to suppressed inspiratory effort.[13][14]
  • Mechanical ventilatory assistance contributes to diaphragm muscle inactivity and unloading, thus leading to diaphragmatic atrophy and fatigue.[15]
  • Diaphragm weakness is a leading cause of difficult weaning from mechanical ventilation[16] and loss of thickness of diaphragm muscle. However, if there is insufficient ventilatory support and the diaphragm is not unloaded adequately this can lead to load-induced inflammation and injury.[17][18]
  • Diaphragm atrophy developed during mechanical ventilation strongly impacts clinical outcomes. Targeting an inspiratory effort level similar to that of healthy subjects at rest might accelerate liberation from ventilation.[19]
