This paper shows a novel approach and a new model to find the relation of formulas between the thermodynamic parameters and electromagnetic parameters, directly and indirectly. Effectiveness of formulas is discussed by considering issues: no thermoregulation process (including body metabolism), no heat transfer consideration, and the Heating loss has not occurred and boundary conditions in a closed system. The enthalpy, internal energy, and Gibbs free energy are perfect indicators for describing bio-reaction in the human body. Because they are state functions (they are independent of intermediate steps, just first and final steps), they are affected by the SAR estimation that represents the absorption power throughout human tissue. These formulas brought in many features to control body reactions or Krebs cycle. Moreover, the derived formulas convert the reaction from non-spontaneous to spontaneous form by converting Gibbs free energy to a negative value. According to findings, the model can be applied in across many disciplines, such as medical treatment, lipid decomposition, cancer healing, and physical therapy. And in the end, as a result of an increase in the concentration of electromagnetic waves in the atmosphere due to technological development, which urges urgently to amend and update all equations to take into account the effect of magnetic waves in all disciplines affected by them.
