On the other hand, air turbulence increases because of the effect of skyscrapers on airflow.
另一方面，摩天大楼对气流的影响导致了空气湍流增加。

Coupled with these factors is the loss of the complex interactions among the muscles that can change the route of airflow from nose to mouth.
与这些因素相结合的是肌肉之间复杂的相互作用的丧失，这种相互作用可以改变从鼻子到嘴的气流路线。

It takes twice as much effort to breathe during sleep because of greater resistance to airflow in the airways and changes in the efficiency of the muscles used for breathing.
