What is normal oral body temperature?
Most people think a normal body temperature is an oral temperature (by mouth) of 37°C (98.6°F). This is an average of normal body temperatures. Your normal temperature may actually be 0.6°C (1°F) or more above or below this.
When summarizing studies with strong or fairly strong evidence the range for oral temperature was 33.2–38.2 °C, rectal: 34.4–37.8 °C, tympanic: 35.4– 37.8 °C and axillary: 35.5–37.0 °C. The range in oral temperature for men and women, respectively, was 35.7–37.7 and 33.2–38.1 °C, in rectal 36.7–37.5 and 36.8–37.1 °C,
- Normal Range. Not everyone's “normal” body temperature is the same. For a typical adult, body temperature can be anywhere from 97 F to 99 F. Babies and children have a little higher range: 97.9 F to 100.4 F.
- Information About Fevers. Normal body temperature is a range between 36.6-37.4 degrees Celcius (C) (97.8-99.3 degrees Fahrenheit (F)) in adults and 36.7-38.0 degrees C (98-100.4 degrees F) in children.
- A fever is a rise in body temperature. Rectal, ear or temporal artery temperature of 100.4 (38 C) or higher. Oral temperature of 100 F (37.8 C) or higher. Armpit temperature of 99 F (37.2 C) or higher.
Normal body temperature varies by person, age, activity, and time of day. The average normal body temperature is generally accepted as 98.6°F (37°C). Some studies have shown that the "normal" body temperature can have a wide range, from 97°F (36.1°C) to 99°F (37.2°C).
- Body temps very from person to person. Usually 98.1 to 98.6 is the normal temp, but mine is usually 96.8 for example. So where it may be low for someone else, it's my normal. So 98.6 would be a fever for me.
- High-grade fevers range from about 103 F-104 F. Dangerous temperatures are high-grade fevers that range from over 104 F-107 F or higher (extremely high fevers are also termed hyperpyrexia).
- It's one of the ways the body defends itself against illness and fights infection. A child's temperature can change slightly during the day, depending on the time of day and how active your child is. Usually, a child has a fever if an oral temperature is above 99.8° F or a rectal temperature is above 100.4° F.
Oral and axillary temperatures average about .5 F to 1.0 F (.3 C to .6 C) degrees below rectal, ear, and temporal readings. Add .5 to 1.0 when taking orally or under the arm to determine the comparable rectal temperature. Have a separate thermometer to use for oral than for rectal.
- The average body temperature, taken with a thermometer in the mouth, is 37ºC (98.6ºF), but anywhere between 36.5ºC and 37.2ºC (97.7ºF and 99ºF) can be considered normal. Armpit temperatures are 0.2ºC to 0.3ºC lower than this. A fever in adults is a temperature of 38ºC (100.4ºF) or above.
- With your mouth open, put the end with the red, blue, or silver-colored tip under your tongue. Close your lips gently around the thermometer. Do not bite the glass thermometer. Keep the thermometer under your tongue for 3 minutes.
- If you take a patient's oral temperature after he's consumed a hot or cold beverage, you'll get an inaccurate reading. Nurses researching this variable found that on average, a patient's temperature doesn't return to baseline for 15 minutes after he drinks a cold beverage.
