Marian suffered from a heat stroke causing her body to experience hyperthermia. Marian body went through the process of homeostasis from experiencing hyperthermia. “Homeostasis is a state of body equilibrium or stable internal environment of the body.”(Marieb 8) Homeostasis protects the body by allowing it to adapt to the environment. Marian homeostasis tried to cool the body but failed. Though Marian was lucky her daughter found her in time. When a heat stroke occurs the body’s homeostasis shuts down where the temperature can reach high enough to cause brain damage to where you die. Heat strokes can cause damage internally well as externally. Hyperthermia causes a positive feedback mechanism within the body. “A positive feedback mechanism is a feedback that tends to cause the level of variable to change in the same direction as an initial change.”( Marieb 9) When the body stimulus rises the hypothalamus’s thermoreceptors start to work as the body’s thermostat. The thermoreceptors send messages allowing the hypothalamus to make temperature changes in the core. When the core starts to raise the heat loss mechanism starts one or two things: “dilation of cutaneous blood vessels or enhanced sweating.”(Marieb 833) “Dilation of cutaneous blood vessels is where the vessels swell with warm blood, heat is lost from the radiation, conduction, and convection” (Marieb 833) Some symptoms for a heat stroke are “throbbing headache, dizziness and light-headedness, lack of sweating despite the heat, red hot skin, muscle weakness or cramps, nausea and vomiting, rapid heartbeat, which may either strong or weak, rapid shallow breathing, behavioral changes such as confusion, disorientation or staggering, seizures, and unconsciousness.”( http://firstaid.webmd.com/heat-stroke-symptoms-and-treatment) The treatments of methodologies for hyperthermia that were used in this case study was to apply cold wash cloth to forehead and face,
