Fever is when a human’s body temperature goes above the normal range of 36–37° Centigrade (98–100° Fahrenheit). It is a common medical sign. Other terms for fever include pyrexia and controlled hyperthermia.

What are the causes of a fever?

• Weather changes
• Rheumatoid arthritis
• Some medications
• Overexposure of skin to sunlight, or sunburn
• Heatstroke, caused by exposure to high temperatures or prolonged strenuous exercise
• Dehydration
• Silicosis, a type of lung disease caused by long-term exposure to silica dust
• Amphetamine abuse
• Alcohol withdrawal

What are the symptoms of a fever?

Symptoms of fevers are based on the severity of them. Common symptoms include:

• feeling cold when nobody else does
• shivering
• lack of appetite
• dehydration — preventable if the person drinks plenty of fluids
• depression
• hyperalgesia, or increased sensitivity to pain
• lethargy
• problems in concentrating
• sleepiness
• sweating
• If the fever is high, there may also be extreme irritability, confusion, delirium, and seizures.

 

Prevention/Treatment

Care for a fever depends on its severity. A low-grade fever with no other symptoms doesn’t typically require medical treatment. Drinking fluids and resting in bed are usually enough to fight off a fever.

When a fever is accompanied by mild symptoms, such as general discomfort or dehydration, it can be helpful to treat elevated body temperature by:

• making sure the room temperature where the person is resting is comfortable
• taking a regular bath or a sponge bath using lukewarm water
• taking acetaminophen or ibuprofen
• drinking plenty of fluids

A visit to a doctor is recommended if fever persists after the home remedies. Oral medication might be prescribed.
