Why Water Part IV - the respiratory system
With the recent COVID-19 pandemic, a lot of attention has been focused on the respiratory system. Typically, respiratory therapists are charged with exercises to improve the lungs capacity to take in air and oxygen, but physical therapy is also a partner player in improving the capacity and efficiency of the respiratory system. So what are the effects of water on breathing and why is breathing important aside from sustaining life?
Water immersion to the chest and up to the neck places pressure (that same hydrostatic pressure previously mentioned) on the chest wall challenging the muscles of inspiration, assisting with expiration. It is a very graded way to naturally improve the strength of breathing muscles and the capacity of the lungs to inflate and take in more oxygen from the air. Deep breathing, especially with movement, assists in reducing stress/pain/tension by helping to turn off the prevalence of fight or flight responses in the body! Ai Chi, similar to Tai Chi, but in water, is one of the more effective ways of practicing coordinated breathing and movement to help in many areas of rehab.
