At least five minutes (same as if you were to eat or drink something then take an oral temperature reading).
You should place the thermometer under your tongue for an accurate oral temperature reading.
It usually takes around 30 seconds to 1 minute to get an accurate oral temperature reading using a digital thermometer. Be sure to keep your mouth closed during the measurement for the most accurate results.
It's typically recommended to wait at least 15-30 minutes after drinking liquids before taking an oral temperature measurement. This allows your mouth temperature to stabilize and provide a more accurate reading.
OXYGEN
If your temperature is taken orally, the temperature of your drink can change the reading on the thermometer. If your temperature is taken rectally or in the axilla, then it wouldn't matter how long it as been since you drank something.
It's best to wait at least 15 to 30 minutes after drinking water before taking your temperature. This allows your body to return to its normal temperature and provides a more accurate reading. Drinking hot or cold beverages can temporarily affect your oral temperature, so waiting is important for reliability.
To take an oral temperature accurately, you should place the thermometer under the tongue towards the back of the mouth. The individual should keep their mouth closed and breathe through their nose for about 3-4 minutes until the thermometer beeps or signals completion. It is important to ensure the individual has not consumed hot or cold beverages within the last 15-20 minutes as this can affect the accuracy of the reading.
10 - 20 minutes
No, a rectal thermometer reading is typically about 0.5 to 1 degree Fahrenheit higher than an oral thermometer reading. So a rectal thermometer reading of 101 degrees would roughly correspond to an oral thermometer reading of 100-100.5 degrees. It's important to use the same type of thermometer for consistent readings.
