The Takeaway
Researchers found that when our cardiac and respiratory cycles sync up, it reduces the mechanical energy lost while pumping blood through the lungs. This synchronization can improve cardiac efficiency by up to 10% in humans and over 50% in other species.
From the abstract
Dissipative coupling is known to induce synchronization. Conversely it may be hypothesized that oscillators driven to synchronize may reduce power dissipation in their coupling. The latter scenario is realized in the human cardiorespiratory system where cardiac and respiratory rhythms are controlled by the central nervous system while interacting viscoelastically through the pulmonary vasculature. Here we examine the functional significance of this coupling which is observed in respiratory sinus
