How Do You Determine The Normal Body Temperature?

Normal body temperature is a fundamental aspect of our health. It serves as an indicator of our overall well-being and can provide essential information for diagnosing and monitoring various medical conditions. But how do you determine what is considered a normal temperature? Here, we will explore the concept of normal body temperature, its variations, the methods of measurement, and the factors that can influence the said normal temperature.

If you are experiencing a high body temperature for a considerable amount of time, getting an appointment with the top hospital in Patna would be the right thing to do.

Understanding Body Temperature Range

Normal temperature refers to the average temperature at which our bodies function optimally. Maintaining a stable body temperature range is crucial because it ensures that our metabolic processes, enzymes, and bodily functions work as they should. The standard unit of measurement for body temperature is degrees Celsius (°C) or degrees Fahrenheit (°F), depending on the region.

The Average Normal Body Temperature

For many years, it was widely accepted that the average normal temperature was 98.6°F (37°C). This value was first established by German physician Carl Wunderlich in the 19th century. However, more recent studies have shown that the average body temperature may be slightly lower, with a range of 97.8°F (36.5°C) to 98.2°F (36.8°C) for adults. Higher than average human body temperature may indicate viral fever. It’s important to note that body temperature range can vary among individuals and at different times of the day.

Variations in Normal Temperature

It’s essential to understand that normal body temperature is not constant. It can move around due to a wide number of factors, including:

Time of Day: Body temperature tends to be lower in the early morning and higher in the late afternoon or evening. This is known as diurnal variation, and it can be influenced by the body’s circadian rhythms. This must be borne in mind when looking for the fever temperature range or high body temperature.

Age: The high body temperature can vary with age. Infants and young children typically have slightly higher body temperatures, while older adults may have slightly lower temperatures. It’s crucial to consider age-related variations when assessing body temperature.

Activity Level: Physical activity, exercise, and strenuous activities can raise body temperature temporarily. It’s common to have an elevated temperature during or after exercise.

Menstrual Cycle: In women, normal body temperature can vary throughout the menstrual cycle. It is generally higher during the second half of the menstrual cycle due to hormonal changes.

Illness and Infection: Infections and illnesses, such as viral fever or bacterial infection, can lead to fever, which is characterized by an elevated fever temperature range. Viral fever is the body’s natural response to fight off infections.

Methods of Measuring Body Temperature

To determine your normal body temperature accurately, several methods can be used:

Oral Temperature: Measuring body temperature orally using a digital thermometer is a common and convenient method, and a fever temperature range can be accessed through this. The thermometer is placed under the tongue, and the reading is typically reliable.

Rectal Temperature: Rectal temperature measurement provides one of the most accurate readings because it is taken internally. It is commonly read for babies and children.

Ear (Tympanic) Temperature: Tympanic thermometers are used to measure temperature in the ear canal. While this method is relatively quick, it may not be as accurate as oral or rectal measurements.

Forehead (Temporal Artery) Temperature: Infrared thermometers can measure body temperature by scanning the temporal artery in the forehead. This method is non-invasive and suitable for all age groups to detect something like high body temperature.

Axillary Temperature: Axillary average human body temperature measurement involves placing a thermometer in the armpit. It is less accurate than oral, rectal, or ear measurements but can provide a general idea of body temperature.

Factors Influencing Normal Body Temperature

Various factors can influence normal body temperature, causing it to fluctuate. It’s crucial to be aware of these factors when determining normal body temperature:

Environment: The surrounding temperature can affect the average human body temperature as well. Exposure to extreme heat or cold can lead to fluctuations in body temperature.

Medications: Certain medications, such as antipyretics (fever-reducing drugs), can lower body temperature, while some drugs may have the opposite effect.

Stress: Stress and emotional factors can influence the body temperature range. Stress-induced changes in the autonomic nervous system can lead to temperature variations.

Hormones: Hormonal fluctuations, such as those associated with the menstrual cycle, pregnancy, or menopause, can affect body temperature in women.

Medical Conditions: Certain medical conditions, such as thyroid disorders, can lead to abnormal body temperature regulation.

Infection: Infections can cause viral fever, which results in a high body temperature. Fever is the body’s response to infection and inflammation. In this case, the body’s temperature usually lies in the fever temperature range.


In summary, determining normal body temperature is not as straightforward as the classic 98.6°F (37°C) once believed. Body temperature varies among individuals, ages, and times of day. Various factors, including environmental conditions, activity levels, and medical conditions, can influence body temperature. To obtain an accurate reading of your body temperature, it is essential to use an appropriate measurement method and consider the factors that may affect your temperature at that moment.

Monitoring your body temperature can be a valuable tool for assessing your health and detecting potential issues. If you notice persistent, unexplained changes in your body temperature or experience fever, consult a healthcare professional for further evaluation and guidance.

Understanding your body’s temperature fluctuations can help you take better care of your overall health and well-being. Visit a super-speciality hospital in Patna today to know more.
