A fever is a sign that something is wrong with your body. It is a very common thing and is characterized by higher than normal body temperatures. Other technical terms for fever are pyrexia and controlled hypothermia.
When you have a fever, your initial reaction might be to take steps to lower your temperature. This is but understandable. However, you also ought to remember that a fever is merely a symptom and the underlying cause can be anything from a mild infection to something that is totally serious. Before doing anything, try to do a little research - what can be wrong? If you have the slightest inkling that the fever can be indicative of something serious, you ought to go to the hospital. Otherwise, there are many home remedies that can help deal with a fever.
As a matter of fact, mild cases of fever may be left untreated. If you are relatively healthy, the fever is probably just your body fighting off germs. With a strong immune system, the fever will disappear shortly. It is important that you rest and keep yourself well hydrated, though.
You can also take over-the-counter medication for fever - acetaminophen, paracetamol, and ibuprofen are popularly used. If you want to feel immediate relief from the heat, try a quick shower (less than 10 minutes) using warm water. Alternatively, a sponge bath will also cool you down.
Fevers with extremely high temperatures - 39.4 degrees Celsius (103 degrees Fahrenheit) - should be monitored closely, and if there is no change in the condition within a couple of days, the patient should be brought to the hospital.
