Body Temperature Monitor (USA)
Monitor your body temperature and identify normal, fever, or hypothermia conditions.
Body Temperature Assessment
Body temperature is categorized based on the following ranges:
Where:
- Temperature: Measured body temperature in °C
- Normal Range: 36.1°C to 37.2°C
- Fever Threshold: ≥37.3°C
- Hypothermia Threshold: <36.1°C

Your current temperature of 36.8°C is normal.
Understanding Body Temperature
The normal human body temperature is typically around 37°C (98.6°F), but can vary between individuals and throughout the day. The accepted normal range is generally considered to be 36.1°C to 37.2°C (97°F to 99°F).
| Method | Normal Range (°C) | Accuracy |
|---|---|---|
| Oral | 36.3-37.2°C | Moderate |
| Rectal | 36.6-38.0°C | Most Accurate |
| Axillary (Underarm) | 35.9-36.7°C | Less Accurate |
| Tympanic (Ear) | 35.8-38.0°C | Accurate |
| Temporal Artery | 36.0-37.5°C | Accurate |
- Fever: Temperature above 38°C (100.4°F) in adults
- High Fever: Temperature above 39.4°C (103°F)
- Hypothermia: Temperature below 35°C (95°F)
- Persistent Fever: Lasting more than 3 days
- Severe Symptoms: Accompanied by severe headache, stiff neck, or difficulty breathing
- Children: Any fever in infants under 3 months
- Chills: Shivering with high temperature
Temperature Knowledge Quiz
The correct answer is B) 36.1-37.2°C. According to the formula provided: Normal temperature is defined as 36.1°C ≤ Temperature ≤ 37.2°C.
The correct answer is C) ≥37.3°C. According to the formula: Fever is classified as Temperature ≥ 37.3°C.
The correct answer is A) True. According to the formula: Hypothermia is defined as Temperature < 36.1°C. Since 36.0°C is less than 36.1°C, it would be classified as hypothermia.
According to the formula:
- Normal: 36.1°C ≤ Temperature ≤ 37.2°C
- Fever: Temperature ≥ 37.3°C
- Hypothermia: Temperature < 36.1°C
Since 37.5°C ≥ 37.3°C, the status is Fever.
The correct answer is C) 37.2°C. The boundary between normal and fever ranges is at 37.2°C (upper limit of normal) and 37.3°C (lower limit of fever). Therefore, 37.2°C is closest to this boundary while still being in the normal range.
Q&A
Q: How do different measurement methods affect temperature readings and what factors influence body temperature variations?
A: Temperature measurements vary significantly by method and numerous factors influence readings:
Measurement Method Differences:
- Rectal: Most accurate, typically 0.5-0.7°C higher than oral
- Oral: Second most accurate, requires 20 minutes post-eating/drinking
- Axillary: Least accurate, typically 0.5-1°C lower than core temperature
- Tympanic: Quick and accurate when properly positioned
- Temporal: Non-contact, good correlation with core temperature
Factors Affecting Temperature:
- Circadian Rhythm: Lowest around 4-6 AM, highest around 4-6 PM
- Age: Infants have higher baseline temperatures
- Activity: Exercise can raise temperature by 1-2°C
- Menstrual Cycle: Slight elevation post-ovulation
- Environmental Factors: Ambient temperature affects readings
For clinical purposes, rectal thermometers provide the gold standard for accuracy.
Q: What are the early signs of hypothermia and when should I seek medical attention?
A: Hypothermia progresses through distinct stages with recognizable symptoms:
Mild Hypothermia (32-35°C):
- Shivering (most prominent sign)
- Increased heart rate and breathing
- Difficulty performing complex tasks
- Slurred speech
Moderate Hypothermia (28-32°C):strong>
- Shivering stops (dangerous sign)
- Confusion and poor judgment
- Decreased consciousness
- Slow, irregular heartbeat
Severe Hypothermia (<28°C):
- Apparent death (undetectable pulse/breathing)
- Fixed, dilated pupils
- Complete unconsciousness
Seek Immediate Medical Attention:
- Temperature below 35°C (95°F)
- Any signs of moderate to severe hypothermia
- Person stops shivering
- Altered mental status
