The effects of the ingestion of hot and cold fluids on the oral and axillary temperatures of a group of healthy individuals. Introduction The purpose of this experiment was to investigate how the ingestion of hot and cold fluid affects the oral and axilla temperatures of a group of 25 volunteers. The group started by establishing their oral and axilla baseline temperatures using a digital thermometer measured in degrees Celsius (°C). They then dissolved an ice cube in their mouths and re-took their temperatures at both locations. After fifteen minutes the volunteers then ingested a hot drink and re-took their oral and axilla temperatures. Temperature is controlled by homeostasis which keeps the body under constant control through a negative feedback mechanism, it is set within a narrow range of 35.5°C to 37.8°C (Waugh and Grant, 2010), although the external environment is constantly changing. The results of the experiment are recorded in the form of a table and a bar chart. Results The results showed that the average oral and axilla baseline temperatures were within the normal range, oral baseline being 36.4°C and the axilla baseline temperature being 35.9°C, although individual 16 was recorded to be below the normal range; it could be due to a faulty thermometer or could be that the subject was cold. After dissolving the ice cube in the mouth the oral temperature fell by an average of 1.6°C to 34.8°C whereas the axilla only fell by 0.5°C. The average oral temperature after drinking hot fluids rose by an average of 1°C to 37.4°C, whereas the axilla only rose by an average of 0.1°C to 36°C.
