The influence of gender and race on mean body temperature in a population of healthy older adults. The decrease in body temperature with age is believed to be a phenomenon arising from a slowing of the human metabolic rate coupled with a decline in the ability to regulate body temperature in response to environmental changes such as seasonal changes, which had been previously studied [17, 19, 22, 47, 48].

Objective To estimate individual level body temperature and to correlate it with other measures of physiology and health. Pooled standard deviations were calculated using the pooled standard deviation formula: For equal sample sizes, the formula was simplified as follows: For the data in which standard deviation for the measured temperatures was not reported in the original articles, the standard deviation was estimated via extrapolation from a plot of the known standard deviations and the corresponding sample sizes. Zero on the Celsius scale (0) is now defined as the equivalent to 273.15K, with a temperature difference of 1 deg C equivalent to a difference of 1K, meaning the unit size in each scale is the same.
