The facts about fever

 

A fever or pyrexia also known as high temperature is not by itself an illness. It's usually a symptom of an underlying condition, most often an infection.

Fever is usually associated with physical discomfort, and most people feel better when a fever is treated. But depending on your age, physical condition, and the underlying cause of your fever, you may or may not require medical treatment for the fever alone. Fever is a natural bodily defense against infection. There are also many non-infectious causes of fever.

Most bacteria and viruses that cause infections in humans thrive best at 98.6 degrees F (37C). Raising the temperature a few degrees can give the body the winning edge. In addition, a fever activates the body’s immune system, accelerating the production of white blood cells, antibodies, and many other infection-fighting agents.

Brain damage from a fever will not occur unless the fever is over 107.6 degrees F (42C) for an extended period of time.

Untreated fevers caused by infection will seldom go over 105 degrees unless the child is overdressed or trapped in a hot place. In a neurologically normal child, the brain’s thermostat will stop the fever from climbing above 106 degrees F.

About 4% of children will sometimes have seizures with fever. These febrile seizures are caused by rapid increase in temperature, not by the height of the temperature. Once a child already has a high fever and a febrile seizure, a febrile seizure is unlikely to reoccur with the current illness. In any event, typical febrile seizures are over in moments with no lasting consequences.

While 98.6 degrees F is considered the normal core body temperature, this value varies between individuals and throughout the day. The daily variation is minimal in children less than six months of age, about 1 degree in children 6 months to 2 years old, and gradually increases to 2 degrees per day by age six. A person’s baseline temperature is usually highest in the evening. Body temperature, especially in children, is normally raised by physical activity, strong emotion, eating, heavy clothing, elevated room temperature, and elevated humidity. Rectal temperatures below 100.4 degrees F (38C) may be entirely normal (no fever). A rectal temperature of 100.4 or above should be considered a fever. Lower values might be a fever, depending on the child.

A fever does not necessarily need to be treated. If a child is playful and comfortable, drinking plenty of fluids, and able to sleep, fever treatment is not likely to be helpful.

Steps should be taken to lower a fever if the child is uncomfortable, vomiting, dehydrated, or having difficulty sleeping. The goal is to bring the temperature between about 100 and 102 degrees F — not to eliminate the fever.

When trying to reduce a fever, first remove excess clothing or blankets. The environment should be comfortably cool. A lukewarm bath or sponge bath may help cool a febrile child. Cold baths or alcohol rubs cool the skin, but often make the situation worse by causing shivering, which raises the core body temperature.

Homeopathic medicines are safe and cure the cause behind the fever. There is no homeopathic medicine to reduce the temperature.
