Most of the cellular enzymes that drive the biochemical reactions necessary for life have an optimal temperature which is usually close to that of the core temperature of the body. In health, core temperature is maintained close to 37°C and this can be regarded as the physiological set point.

The normal range for core temperature is extremely narrow at between 36.1°C and 37.2°C (Figure 2.2). To ensure core temperature is maintained close to 37°C, the human body has some very elaborate and highly coordinated physiological responses.
