A fever is a temporary increase in your body temperature, often due to an illness. It’s a natural response of your body’s immune system to fight off infections, such as those caused by viruses or bacteria. While a fever can be uncomfortable, it’s usually not harmful and often signals that your body is working to recover. For adults, a fever is generally considered to be a temperature of 100.4°F (38°C) or higher. In children, the definition can vary slightly depending on age and measurement method, but generally, it’s also around 100.4°F (38°C) or higher rectally.

Common Causes of Fever
Fevers are most commonly caused by infections. These infections can be viral, like the common cold or flu, or bacterial, such as strep throat or urinary tract infections. In many cases, a mild fever, ranging from 102°F to 104°F (38.9°C to 40°C), can be attributed to a simple cold or another viral infection. It’s important to remember that a high fever in these instances doesn’t automatically indicate a serious condition. Conversely, some serious infections might not even cause a fever, or in infants, might even lead to a dangerously low body temperature.
Recognizing When a Fever is Not Serious
It can be concerning when you or your child develops a fever, but often, it’s a sign of the body fighting off a minor illness effectively. For children, certain behaviors and signs can be reassuring indicators that the illness is likely not serious. These include:
- Continued interest in play: If a child with a fever is still engaging in play and activities they enjoy, it’s a positive sign.
- Good appetite and fluid intake: Maintaining normal eating and drinking habits despite the fever suggests they are not severely ill.
- Alertness and responsiveness: Being alert, smiling, and interacting with you normally are good indicators.
- Normal skin color: Healthy skin color when the fever is present is a reassuring sign.
- Improved condition with temperature reduction: If the child appears to feel and look better once their temperature comes down, it often signifies a less serious illness.
If these signs are present, and the fever is mild, often no specific treatment beyond rest and fluids is necessary.

Managing a Fever for Comfort
While a fever itself isn’t always dangerous, it can cause discomfort. Managing a fever focuses on relieving symptoms and ensuring comfort, not necessarily eliminating the fever entirely. It’s appropriate to take steps to lower a fever if you or your child is experiencing discomfort, vomiting, dehydration, or difficulty sleeping.
Non-Medication Methods to Reduce Fever:
- Light clothing and comfortable room temperature: Avoid overdressing or bundling up, especially if chills are not present. Dress in lightweight clothing and maintain a comfortable room temperature. If the room is stuffy, a fan can help improve air circulation.
- Lukewarm bath or sponge bath: A lukewarm bath can be effective in cooling down someone with a fever, particularly after fever-reducing medication has been administered. Avoid cold baths, ice, or alcohol rubs as these can cause shivering, which paradoxically raises the core body temperature.
Medication for Fever Reduction:
Over-the-counter medications like acetaminophen (Tylenol) and ibuprofen (Advil, Motrin) are effective in reducing fever in both children and adults.
- Acetaminophen (Tylenol): Can be taken every 4 to 6 hours and works by affecting the brain’s temperature control center.
- Ibuprofen (Advil, Motrin): Can be taken every 6 to 8 hours. It’s not recommended for children under 6 months old.
- Aspirin: Effective for adults but should not be given to children unless specifically advised by a healthcare provider due to the risk of Reye’s syndrome.
Always follow dosage instructions on the packaging and consider your or your child’s weight for accurate dosing. For children 3 months and younger, it’s crucial to consult a healthcare provider before administering any fever-reducing medications.

Staying Hydrated and Nourished
Proper hydration is crucial during a fever, especially for children. Encourage plenty of fluid intake such as water, ice pops, soup, and gelatin. For younger children, limit sugary drinks like fruit juice and avoid sports drinks. While eating is acceptable, do not force food if appetite is reduced.
Conclusion
Understanding what a fever is, its common causes, and how to manage it can help alleviate concerns and ensure appropriate care. Most fevers, especially mild ones associated with common viral illnesses, are not dangerous and resolve on their own with rest and supportive care. However, it’s always important to monitor symptoms and seek medical advice if you have concerns or if the fever is accompanied by other worrying signs.
