Temperature is an essential indicator of our overall health, making it crucial to keep an eye on it. Our body temperature varies throughout the day, but typically, the average body temperature is around 98.6°F or 37°C. Several factors can impact the body temperature, including age, environment, and physical activity. Measuring core body temperature can help detect potential health issues, make informed medical decisions, and safeguard your health. Below is a complete guide on how to measure core body temperature.
###What is core body temperature?
Core body temperature is the internal temperature of our body, measuring the heat produced by metabolic functions of our organs and muscles. Unlike surface temperature, which measures the heat around our skin, core body temperature helps identify the temperature variations inside our body, affecting our vital organs, including heart, lungs, brain, and liver. Our body maintains core body temperature, balancing heat production and heat loss of the body.
###Why is it essential to measure core body temperature?
The body temperature is an indicator of how the body is functioning. Keeping track of core body temperature can help in several ways, such as:
1. Detecting infections – Core body temperature rises when the body is fighting against infections or illnesses such as the flu or pneumonia.
2. Monitoring reproductive health – Women who are trying to conceive should monitor their basal body temperature or the body temperature after they wake up, to determine the ovulation phase or fertility period.
3. Identifying hypothermia or heat stroke – Hypothermia or heat stroke poses a severe threat to your health. Detecting the early signs, including fluctuations in body temperature, can prevent health complications.
###Ways to measure core body temperature
1. Oral temperature: The oral temperature measurement is done by placing a thermometer under the tongue for 3-4 minutes. It is the most common and convenient way of measuring the core body temperature, especially in adults. During the measurement, it is essential to breathe through the nose.
2. Rectal temperature: Rectal temperature is the temperature measurement of the rectum, which provides an accurate reading of the body temperature. This method is most commonly used for infants and young children when oral temperature measurements are difficult. This method is not suitable for those with rectal problems or bleeding.
3. Axillary temperature: Axillary temperature is the temperature measured under the armpit. This method is typically less accurate as the reading can vary based on the thickness or moisture level of clothes, but it is the safest method for infants.
4. Ear temperature: Ear temperature measurement is done using an infrared thermometer, which records the temperature by detecting the temperature radiation in the ear. It is a quick and easy way to measure body temperature, and the reading is relatively accurate.
5. Temporal artery temperature: The temporal artery temperature is measured by placing an infrared scanner over the temporal artery in the forehead. It is suitable for checking the temperature of infants and young children without disturbing their sleep. It is also used in hospitals and clinics as it can provide accurate readings.
###Tips to ensure accurate measurement
1. Measure at the correct time: It is essential to measure the body temperature at the right time to get accurate readings. While oral temperature can be taken any time of day, rectal temperature readings should be taken in the early morning before eating or drinking.
2. Wait before measuring: If you have been exercising or exposed to cold or hot temperatures, wait for 30 minutes before measuring the temperature.
3. Choose the right thermometer: There are several types of thermometers available, and it is essential to choose the right one for the specific type of measurement.
4. Avoid using shared thermometers: It is best to avoid sharing thermometers to prevent cross-infection.
###Conclusion
Measuring core body temperature is an essential aspect of determining overall health and detecting potential health risks. Although several methods are available, individuals should opt for a suitable method and avoid exposing themselves to environmental factors that may distort the readings. Accurate measurements can help individuals make informed decisions about their health, prevent health complications, and maintain their overall well-being.
