Unlike many small mammals that pant to cool their bodies, humans employ surface sweating as the main effector for heat loss. It may be surprising but human breathing also responds changes in body temperatures. Both a thermal panting response is evident in the heat and a pronounced gasp response is a characteristic response in the cold. The primary objective of my research program is to establish the mechanisms of control of human breathing after changes in body temperature. My research hypothesis is that high or low body temperatures provide an important stimulus to human breathing.

与许多通过喘气来冷却身体的小型哺乳动物不同，人类利用表面出汗作为热量损失的主要效应器。这可能令人惊讶，但人类的呼吸也会对体温的变化做出反应。热喘息响应在热时是明显的，而明显的喘息响应是冷时的特征响应。我的研究项目的主要目标是建立人体体温变化后呼吸的控制机制。我的研究假设是，高或低的体温为人类呼吸提供了重要的刺激。
