When we are unwell, feeling stuck, depressed or lacking in drive we have too little prana within the body, we have more of it outside our body instead.

When we are unwell, feeling stuck, depressed or lacking in drive we have too little prana within the body, we have more of it outside our body instead. The reason for this is because the prana in the body is forced out by something else, something that does not belong there which we call rubbish. When we practice pranayama we are clearing this “rubbish” from our body and so allowing more and more prana to be within the body instead of outside it. "When we practice pranayama the veil is gradually drawn away from the mind and there is growing clarity. The mind becomes ready for deep meditation" (yoga sutra). So by practicing pranayama we are clearing the obstacles in our bodies, allowing breath and energy (prana) to flow freely. Our breathing is improved, our bodies function better and we clear and calm the mind. ‪Pranayama techniques focus on one or more of the four parts of the breath: Inhalation (puraka), Internal retention (antara-khumbaka), Exhalation (rechaka),External retention (bahya-khumbaka). The exhalation is said to be the most important part of the breath - only when we can exhale and empty fully can we take a full new inhalation. The goal of Pranayama is to increase the quantum of this life force (Prana) so that it can reach out to 'hidden' recesses of the brain. This helps in expanding the human faculties and retarding degeneration.
