Temperature Regulation

Abstract

For the body’s enzymes and biological processes, a certain body temperature is necessary. In humans, the temperature optimum is from 36.4 °C to 37.4 °C. A slight rise of the temperature can increase body processes for a short time. Temperatures above 39.5 °C could affect the body negatively. If these temperatures persist longer, it might result in heat-related injuries. It can cause seizures, destruction of muscle tissue (rhabdomyolysis), hypotension, shock, etc. Temperatures above 43 °C are usually fatal. In body temperatures below 36.4 °C, body processes slow down. 26 °C and 28 °C are regarded as critical benchmarks, as heart arrhythmias and CNS changes may occur.
