Postoperative fever refers to an elevated body temperature (≥ 38.5 °C) occurring after a recent surgical procedure. Diagnosing the cause of postoperative fever can sometimes be challenging; while fever in this context may be benign, self-limited, or unrelated to the surgical procedure, it can also be indicative of a surgical complication, such as infection.
Skin temperature is the temperature of the outermost surface of the body. Normal human skin temperature on the trunk of the body varies between 33.5 and 36.9 °C (92.3 and 98.4 °F), though the skin's temperature is lower over protruding parts, like the nose, and higher over muscles and active organs.

The type of wound (incision, laceration, puncture, etc.) has a major effect on the way a wound is managed, as does the area of the body affected and presence of any foreign objects in the wound. A serious wound or any complication may require a call to emergency medical services. Any wound requires being disinfected after it stops bleeding.
Studies have shown that the body activates the hunting reaction after only 10 minutes of cryotherapy, at temperatures less than 9.5 °C (49 °F). The hunting response is a cycle of vasoconstriction (decreased blood flow), then vasodilation (increased blood flow) that increases the delivery of oxygen and nutrient rich blood to the tissue.

Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
The heat index, also referred to as the apparent temperature, is what the temperature feels like to your body when relative humidity is combined with the air temperature. If you get too hot, you ...
A normal human body needs a pressure gradient for blood flow. [43] It must go from the higher-pressure arterial system to the lower-pressure venous system. [5] [43] This causes blood to back up. [5] Excess fluid leaks from the capillaries into the spaces between the soft tissue's cells. [44]
