Recent uses of infrared colour thermography in environmental physiology are outlined. These include analysis of the normal thermogram and recording, on colour cine film, the temperature changes that occur during exercise. Skin temperatures in warm ambient conditions and during exposure to direct sunlight have also been recorded and the cooling effect of a hot drink in warm weather has been demonstrated. The use of thermography to assess the effectiveness of garments for use in the harsh conditions beneath hovering helicopters is described.
