Body temperature readings taken from the armpit are generally lower than those taken from the mouth or rectum. This is because the armpit is not in direct contact with the body’s core, and the temperature there is influenced by the surrounding air. When using the armpit to measure temperature, it may take a bit longer for the thermometer to register the correct reading. As a result, readings from the armpit might be slightly less accurate and usually need to be adjusted by about 0.5°C higher to match other methods.
