Human Body Temperature

          Human Body Temperature

Human body temperature, generally considered normal around 98.6°F (37°C), naturally fluctuates throughout the day and is influenced by factors like age, activity, and time of day, with a typical range of 97°F to 99°F.

The average normal body temperature is generally accepted as 98.6°F (37°C). Some studies have shown that the "normal" body temperature can have a wide range, from 97°F (36.1°C) to 99°F (37.2°C).

This study aims to further explore the relationship between body temperature and thermal perception, and thus four kinds of body temperatures (skin temperature, oral temperature, auditory canal temperature and breath temperature) were selected as the research objects.

Our internal body temperature is regulated by a part of our brain called the hypothalamus. The hypothalamus checks our current temperature and compares it with the normal temperature of about 37°C.

Average:

        The average normal body temperature is 98.6°F (37°C).

Range:

      That a normal body temperature can range from 97°F (36.1°C) to 99°F (37.2°C). 

Variations:

Time of Day:

            Body temperature is typically lowest in the early morning and highest in the late afternoon/early evening.

Activity Level:

               Physical activity can raise body temperature.

Age:

    Babies and children may have slightly higher normal temperatures than adults.

Menstrual Cycle:

               In women, body temperature can fluctuate during the menstrual cycle, peaking around ovulation.

Measurement Methods:

Oral:

     98.6°F (37°C) is the standard for oral temperature.

Rectal:

      Rectal temperature is typically 0.27° to 0.38°C (0.5° to 0.7°F) higher than oral temperature.

Axillary (Armpit):

                 Axillary temperature is about 0.55°C (1.0°F) lower than oral temperature.

Hypothermia:

.A rectal temperature of 35°C (95°F) or less is considered hypothermia.

.Hypothermia can be a dangerous emergency condition.

Fever:

.A temperature above 100.4°F (38°C) is generally considered a fever

.Fever is often a sign of the body fighting off an infection or illness.
