These two concepts are sometimes used interchangeably but the fact is that Haar may be considered as the action potential of the body whilst the heat being one of the byproducts of Haar’s actions. The Haar, is distributed throughout the body by its source, the heart, and ventilated by the heartbeat and breath. Two movements have been described for the Haar: the normal expansion and distribution of Haar to the periphery of the body, and the constriction and condensation of Haar in the core of the body. These currents may both be physiologic or pathologic depending on the duration, strength and extent of each movement. Considering the importance of the balance between these movements, and the dependence of Haar on heat to stay in optimal state, it is proposed that external heat therapy can be used to treat various diseases by strengthening the pump of the Haar (the heart), and opening its pathway (the vessels). Named SINA, this modified sauna therapy is highly individualized, corresponding to the patient’s temperament, and at the same time monitored and managed based on emergence of warning symptoms. Thus, SINA therapy opens a whole new perspective in treatment of a wide range of diseases by means of the body’s own powerful potential, the Haar.  https://jtim.tums.ac.ir/index.php/jtim/article/view/70 https://jtim.tums.ac.ir/index.php/jtim/article/download/70/82
