Abstract
IT was found that when men stayed in air-conditioned rooms at about 30° C. for a few days their packed red-cell volume fell1,2. A rise in this value was likewise found in conditions of low environmental temperature2. More prolonged exposure to conditions of high environmental temperature caused by change of season was also associated with a fall in the packed red-cell volume3. No satisfactory information about the physiological effect on the packed red-cell volume of people living for several months or years in a warm climate could be found in the available literature. The results of an investigation made in Singapore may, therefore, be of interest.
