As we know, 36.8° Celsius or 98.24° Fahrenheit is the normal temperature of human body. These are the exact figures, but most of take them to be 37° Celsius or 98° Fahrenheit. A medical use thermometer for measuring human body temperature is often calibrated with Fahrenheit units. Therefore, a reading above 98.24° Fahrenheit on your thermometer would indicate high fever.
High fever is a condition in which an organism’s body gets heated up beyond its normal temperature. This could happen because of external factors. Sometimes even body raises its own temperature as a defense mechanism against pathogens and other conditions.
Facts About Fever
- Normal body temperature can range between 36.5°C (97.7°F) to 37.5°C (99.5°F). Some people may have a normal temperature which is slightly higher than the average 98.24° Fahrenheit.
- Hypothalamus, a part of the brain, is responsible for controlling the body temperature.
- Human body temperature slightly varies throughout the day.
- Common infections such as colds and gastroenteritis are the most common causes of fever.
- Opposite of fever (i.e. body temperature higher than normal) is hypothermia (i.e. body temperature lower than normal)
- Temperature can be measured from various parts of the body:
- Mouth: most commonly human body temperature is measured from person’s mouth.
- Rectum: measured temperature will be 0.5 to 0.7°F higher than the reading taken from mouth.
- Armpit: measured temperature will be 0.3 to 0.4°F lower than the reading taken from mouth.
Normal Human Body Temperature
There is no universal normal human body temperature. It varies a little from person to person and also depends on the age of the person.
Normal Body Temperature for a Baby
The American Academy of Pediatrics (AAP) states that for a healthy human baby the normal body temperature (measured in rectum) is between 97°F and 100.3°F.
Normal Body Temperature for Children
According to the American Academy of Pediatrics normal body temperature for a human child is between 97°F and 100.4°F (36°C to 38°C degrees Celsius).
Normal Body Temperature for Adults
Normal body temperature in human adults, if measured in the mouth, is about 36.8°C (98.2°F). If temperature is taken in armpit then the normal reading should be around 36.5°C (97.7°F). Normal body temperature in body cavities like rectum, vagina, or in the ear is about 37.5°C (99.5°F).
