Cold‐related and Heat‐related Medical Problems

Abstract

The great majority of illness and mortality caused by heat and cold is produced indirectly through promotion of various disease processes and injuries. Other complications of this nature are due directly to cooling or overheating of the body core (hypothermia or hyperthermia).

Keywords: seasonal mortality; hypothermia; frost bite; hyperthermia; heat stroke

Fall of body temperature of fat and thin people in water at 15°C for 30 min. From Keatinge (1960).

Figure 2.

Changes in air temperature and mortality associated with a cold day, south‐east England. Mortality is shown as deaths per 106 population per °C depression of temperature on the cold day (day 0), compared with baseline. From Donaldson and Keatinge (1997).
