Body temperature is a crucial indicator of our overall health, and taking it correctly is essential for accurate diagnosis and treatment. One common method of measuring body temperature is under the armpit, also known as axillary temperature measurement. However, many people are unsure what the normal temperature range is under the armpit. In this article, we will explore the normal temperature range under the armpit, factors that can affect it, and provide tips for accurate body temperature reading.
Understanding Body Temperature
Body temperature is regulated by the hypothalamus, a small region in the brain that acts as the body’s thermostat. The normal body temperature range for adults is generally considered to be between 97.7°F (36.5°C) and 99.5°F (37.7°C). However, this range can vary slightly from person to person, and it’s not uncommon for body temperature to fluctuate throughout the day.
Normal Temperature Under the Armpit
The normal temperature range under the armpit is slightly higher than the oral or rectal temperature range. According to the American Academy of Pediatrics, a normal axillary temperature is between 97°F (36°C) and 100.4°F (38°C). However, a study published in the Journal of Pediatrics found that the average axillary temperature for healthy adults is around 98.6°F (37°C).
| Temperature Range | Axillary Temperature |
|---|---|
| Normal | 97°F - 100.4°F (36°C - 38°C) |
| Average | 98.6°F (37°C) |
| Fever | Above 100.4°F (38°C) |
Key Points
- The normal temperature range under the armpit is between 97°F (36°C) and 100.4°F (38°C).
- The average axillary temperature for healthy adults is around 98.6°F (37°C).
- Body temperature can fluctuate throughout the day and is influenced by various factors, such as age, sex, and physical activity level.
- Axillary temperature measurement is a non-invasive and easy-to-use method, but it may not be as accurate as other methods, such as rectal or oral temperature measurement.
- A fever is generally considered to be a temperature above 100.4°F (38°C).
Factors That Can Affect Body Temperature
Several factors can affect body temperature, including:
- Age: Infants and young children tend to have higher body temperatures than adults.
- Physical activity: Engaging in physical activity can increase body temperature.
- Environmental temperature: Exposure to extreme temperatures can affect body temperature.
- Hormonal changes: Hormonal fluctuations during menstruation or menopause can affect body temperature.
- Medical conditions: Certain medical conditions, such as hypothyroidism or hyperthyroidism, can affect body temperature.
Tips for Accurate Body Temperature Reading
To ensure accurate body temperature reading, follow these tips:
- Use a digital thermometer specifically designed for axillary temperature measurement.
- Place the thermometer under the armpit, making sure it’s in contact with the skin.
- Hold the thermometer in place for the recommended time, usually 1-2 minutes.
- Wait for the thermometer to beep or display the temperature reading.
- Record the temperature reading and time of day.
Conclusion
In conclusion, the normal temperature range under the armpit is between 97°F (36°C) and 100.4°F (38°C), with an average temperature of around 98.6°F (37°C). Factors such as age, physical activity, and environmental temperature can affect body temperature. By following proper techniques for axillary temperature measurement and considering individual factors, healthcare professionals and individuals can accurately assess body temperature and detect potential health issues.
