A fever is a sign that the body's natural defense against infection is working. Before calling a doctor, take note of other symptoms, such as headache, lethargy, loss of appetite and chills, which may be more important than fever.
Body temperature varies according to time of day, gender, hormones, age and other factors.
Temperature tends to be lower in the morning and higher in the evening. Return to Health Information Page Return to Main Page Click here to tell us how we may better meet your health care needs.
