Introduction
If the body temperature is measured correctly (e.g., drying sweat before axillary measurement and remaining at rest for 5–10 minutes) and under stable environmental conditions (without immediate measurement after vigorous exercise or emotional excitement), a temperature of 37°C falls within the normal physiological range. In the absence of symptoms such as fatigue, chills, or other discomforts, there is no need to worry about fever—this represents a normal body temperature state.
Under normal circumstances, a body temperature slightly above 37°C is not considered a fever. The typical normal temperature range is generally 36.0–37.2°C. Only when there are special measurement errors or individual baseline abnormalities should one be cautious. If in doubt, it is recommended to seek medical advice early. Detailed analysis is as follows:
If the temperature is measured correctly (e.g., drying sweat before axillary measurement and remaining at rest for 5–10 minutes) and under stable conditions (without immediately measuring after intense exercise or emotional excitement), a reading of 37°C falls within the normal range. In the absence of symptoms such as fatigue or chills, there is no need for concern about fever—this represents a normal body temperature state.
If improper measurement techniques occur (such as sweat under the arm or insufficient measurement time), or if an individual normally has a baseline temperature consistently below 36.0°C, then 37°C might be slightly elevated relative to their personal norm. If accompanied by mild symptoms like dizziness or muscle aches, repeat the measurement properly to confirm the result and rule out misinterpretation due to measurement error. In such cases, fever should not be diagnosed immediately.
For daily temperature monitoring, it is advisable to measure at the same time and same body site consistently to ensure uniform measurement conditions. If repeated measurements show significant fluctuations or persistent discomfort occurs, seek timely medical evaluation to determine the underlying cause of temperature changes.
