Abstract
PEOPLE resident at sea-level in the equatorial tropics are considered to be ‘naturally’ acclimatized to heat1. There is evidence that the indigenous peoples of these regions have low forearm blood flows and systolic blood pressures in relation to their surface and deep-body temperatures2–4. This evidence seems to indicate that the cardiovascular systems of heat-acclimatized people are relatively insensitive to increases of body temperature. If this is true, the relationship between the heart-rates and sub-lingual temperatures of tropical people would be expected to differ from that of people who are not acclimatized to heat. The relationship between the heart-rates and sub-lingual temperatures of young English subjects, at rest in a temperate climate, has been investigated by Tanner5. Comparable data are not available for the indigenous peoples of the tropics.
