I’m not clear on why the axillary temperature is a better indicator of body temp than taking an oral temp? Thanks in advance!

Oral temperature is an unreliable measure of a person’s metabolism because of the high frequency of sinus infections, oral infections, allergies, and upper respiratory infections which affect a person with hypothyroidism. The presence of these conditions will raise the oral temperature above what represents metabolism. When monitoring temperature to determine metabolism (and hence thyroid function), the armpit or axillary temperature is the better temperature to obtain.
I follow this in this link and I still from time to time check my basal temps in the morning just to see how my levels are.

You can print off the chart in this link and keep track of your temps avg.Actually,an axillary temperature will typically read about one-half to one degree lower than an oral temperature and a rectal temperature will typically read a degree higher than an oral temperature.Tympanic temperature is about equivalent to oral temperature.Axillary temperature is the least reliable from an accuracy standpoint and in order to obtain the actual reading, the armpit should be dry and the person free from any activity or exercise for at least 20 minutes or so.Oral temperatures can be affected by taking in liquids within the period proximal to testing the temperature.
Most people think of a “normal” body temperature as an oral temperature of 98.6°F (37°C). This is an average of normal body temperatures. Your temperature may actually be 1°F (0.6°C) or more above or below 98.6°F (37°C). Also, your normal body temperature changes by as much as 1°F (0.6°C) throughout the day, depending on how active you are and the time of day. Body temperature is very sensitive to hormone levels and may be higher or lower when a woman is ovulating or having her menstrual period.
Well, an oral temperature is actually more accurate when you compare it to the axillary temperature. An axillary temperature is actually influenced by the fact that the temperature on the outer surface of the body is being measured. Having said that, if you are dealing with very small kids- you are probably better off with an axillary temperature. It is nearly impossible and dangerous to try out an oral temperature with an infant!
