Thermal comfort has been the area, which is explored extensively by the researchers to improve the performance of human being. This vast field has been studied by two different broad ways, namely experimental and theoretical. This paper comprehensively reviews these two methodologies in detail. The experimental study in this field has been categorized through two different ways, adaptive and rational. In former, the experiments are performed in the actual environment and in later, the experiments are performed in a climate simulator. This paper also reviews the theoretical study by discussing different mathematical models which are required in the study. Different ways of theoretical analysis, namely steady-state and transient state, have been reviewed along with solving methods. Different factors affecting thermal comfort have been summarized. At last, future scope related to this field has been discussed.

热舒适性一直是该领域，研究人员对其进行了广泛的探索以改善人类的表现。已经通过两种不同的广泛方式对这一广阔领域进行了研究，即实验和理论。本文对这两种方法进行了详细的全面回顾。该领域的实验研究已通过两种不同的方式进行了归类，即自适应和理性。前者是在实际环境中进行实验，后者是在气候模拟器中进行实验。本文还通过讨论研究中需要的不同数学模型来回顾理论研究。已经讨论了不同的理论分析方法，即稳态和瞬态，以及求解方法。总结了影响热舒适性的不同因素。
