Why does my temperature increase?
Hyperthermia is an increase in body temperature over the temperature set point, due to either too much heat production or not enough heat loss. It is an example of a high temperature phenomenon that is not a fever; rather, it occurs from a number of causes including heatstroke, neuroleptic malignant syndrome, malignant hyperthermia, as well as in response to stimulants such as substituted amphetamines and cocaine, and in idiosyncratic drug reactions, and serotonin syndrome. Hyperthermia differs from hyperpyrexia, see section following.
How does the hypothalamus regulate temperature?
Temperature is regulated in the hypothalamus. The trigger of a fever , called a pyrogen, results in the release of prostaglandin E2 (PGE2). PGE2 in turn acts on the hypothalamus , which creates a systemic response in the body, causing heat-generating effects to match a new higher temperature set point. Hence, the hypothalamus can be seen as working like a thermostat. When the set point is raised, the body increases its temperature through both active generation of heat and retention of heat. Peripheral vasoconstriction both reduces heat loss through the skin and causes the person to feel cold. Norepinephrine increases thermogenesis in brown adipose tissue, and muscle contraction through shivering raises the metabolic rate.
