The effect of hot beverages, cold beverages, and chewing gum on oral temperature

"BACKGROUND: A prospective blood donor's oral temperature is affected
by external stimuli such as drinking a hot or cold beverage..."

"RESULTS: The drinking of a hot beverage caused an immediate mean
temperature elevation of 2.6°F..."
