Afterdrop is attributed to the return of cold blood from extremities to the core due to peripheral vasodilatation, thus causing a further decrease of deep body temperature. [1] However a second theory explains afterdrop as a side effect of conductive heat transfer. "The hypothermic patient cools from the outside in.
However, if the temperatures are too high, or if they are kept elevated for too long, then serious side effects, including death, can result. The smaller the place that is heated, and the shorter the treatment time, the lower the side effects. Conversely, tumor treated too slowly or at too low a temperature will not achieve therapeutic goals.
Heat stroke is an acute temperature elevation caused by exposure to excessive heat, or combination of heat and humidity, that overwhelms the heat-regulating mechanisms of the body. The latter is a relatively rare side effect of many drugs, particularly those that affect the central nervous system.
Superficial moist heat is a great alternative can help calm abdominal muscle cramps associated with dysmenorrhea without the adverse effects of menstruation. Moist heat can also improve pelvic circulation that further helps reduce pain. [24] Heat therapy is shown to assist women with pain and reduce the duration of the first stage of labor.
Leidenfrost droplet Demonstration of the Leidenfrost effect Leidenfrost effect of a single drop of water. The Leidenfrost effect is a physical phenomenon in which a liquid, close to a solid surface of another body that is significantly hotter than the liquid's boiling point, produces an insulating vapor layer that keeps the liquid from boiling rapidly.
Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes.

Diathermy is commonly used for muscle relaxation, and to induce deep heating in tissue for therapeutic purposes in medicine. It is used in physical therapy to deliver moderate heat directly to pathologic lesions in the deeper tissues of the body.
