Theanal temperature is the best way to measure the core temperature of the body.

1. Actually, anal temperature is measured in ambulatory facilities where oral temperature cannot be measured due to certain oral surgeries or if the person is on a ventilator or non-responsive or gets seizures.
2. However, in your case, in a daily day-to-day life, when there are no such concerns troubling you, then you should continue with oral temperature monitoring.
3. If you find it unhygienic, then thermometer can be placed under an armpit for the same amount of time.
4. Anal temperature recording is considered invasive and often uncomfortable, so I would not recommend a switch. But, you may use it twice a week or so.

1. A rectal temperature is generally considered to be the most accurate and standard for monitoring the core body temperature.
2. It is generally not recommended for use in patients due to the risk of rectal perforation and tears with this method.
3. However, under supervision, it can be used. Of course, as mentioned above when the patient is non-co-operative, unconscious, under seizure or especially in toddlers and infants, this is the best way to measure temperature but not routinely.
4. Oral and axillary temperatures average about 0.5 F to 1.0 F (0.3 C to 0.6 C) degrees below rectal temperature. Add 0.5 to 1.0 F when taking orally or under the arm to determine the comparable rectal temperature.
