Your body temperature is usually highest
in the evening. It can be raised by physical activity,
strong emotion, eating, heavy clothing, medications,
high room temperature, and high humidity. This is especially
true in children.
A rectal temperature up to 100.4°F
(38°C) may be entirely normal. A rectal temperature
of 100.5°F or above should always be considered a fever.
Lower temperatures might also be a fever, depending
on the person.
Fever is not an illness. Far from being an enemy,
it is an important part of the body's defense against
infection. Many infants and children develop high fevers
with minor viral illnesses. While a fever signals to
us that a battle might be going on in the body, the
fever is fighting for the person, not against.
