ABOUT NORMAL BODY
TEMPERATURE AND
FEVER
Body temperature can vary from person to
person. It also varies on different parts of the
body and time of day. The following table shows
the statistics of normal ranges from different body
parts. Please keep in mind that temperatures
measured from different body parts, even at the
same time, should not be directly compared.
Fever indicates that the body temperature is
higher than normal. This symptom may be caused
by infection, overdressing or immunization. Some
people may not experience fever even when
they are ill. These include, but are not limited
to, infants younger than 3 months old, persons
with compromised immune systems, persons
taking antibiotics, steroids or antipyretics (aspirin,
ibuprofen, acetaminophen), or persons with
certain chronic illnesses. Please consult your
physician when you feel ill even if you do not
have a fever.
