直立姿势的假设需要重新调整，这会影响身体的每一个解剖结构，并改变所有重要的生理过程。1.这种姿势的第二个结果是，身体的许多空间都位于重力的作用下，使它们的内容物堆积在离自然出口最远的地方。在直立位时，上呼吸道位于下呼吸道上方，可以自由地流入下呼吸道，即使在仰卧位时，如果在患者熟睡时将曲碘油引入鼻咽，也会进入支气管。2这一事实解释了鼻腔感染与支气管感染的密切关系。由于习惯的力量，大多数人睡两个枕头，呼吸道感染的患者提供了两倍或三倍的这个数字，所以采用重力排水是不可能的位置。
The assumption of theupright posture has necessitated readjustments which affect every anatomical structure in the body and modify all the vital physiological processes. 1 As a secondary outcome of this posture many spaces of the body are so situated that gravity causes their contents to accumulate farthest from theirnatural outlet. In the upright position the upper respiratory tract is situated above the lower respiratory tract and can drain freely into it, and even in the supine position lipiodol, if it is introduced into the nasopharynx while the patient is heavily asleep, will enter the bronchi. 2 This fact explains the closerelation between nasal and bronchial infection. Through force of habit the majority of people sleep with two pillows, and patients with respiratory infections are provided with twice or three times this number, so adopting a position in which gravity drainage is impossible.
