Muscle Strength, Illness, Mind

What is the connection? The connection is ventilation, the motor aspect of breathing. The part that involves the skeletal muscles. Healthy and strong skeletal muscles are necessary to move air in and out of the body and lungs. And air, adequate exchange of air in the lungs, is key to a fully functioning mind.

Breathing is a necessary function of life, and most of the time it is effortless, unless you are like Paula.

 For most of us breathing is not given much consideration. That’s because breathing is under autonomic nerve control. The signals are sent from the brain automatically. The brain determines when we need to breathe based on the signals  it receives from our organs and nerves. Although we can breathe in and out on command – for example, during pulmonary function testing or when completing breathing exercises – respiratory muscle function is primarily an automatic task.
