Avoid overusing fever-reducing medication.

"In most cases, the fever should be left as it is. Evidence suggests that lowering the fever can hinder a patient's recovery from infection," said Dr. Paul Young.

Recently, it has been observed that the negative aspects of treating fever manifest in several ways: Increased mortality rates due to infection in animals;runny nose symptomsWhen a child's cold gets worse; blisters in children with chickenpox take longer to heal; the immune response in children after vaccination is weaker.

It's something almost everyone knows: fever is very useful in preventing infection. Before humans invented it...antibioticsIn the late 19th century, a fairly common approach to treating common illnesses was based on fever. However, nowadays people are more interested in reducing fever, a trend that seems to lack any scientific evidence and is also due to the increasing variety and accessibility of medications.

The reason we try to lower a fever when we see our body temperature rising is because we fear the temperature will continue to increase, potentially damaging the brain and other organs. The truth is, while temperatures above 41 degrees Celsius can be dangerous, such high fevers usually only occur in events like strokes, when the body's thermoregulation mechanism is disrupted.

Although high fevers caused by infections can trigger seizures or lethargy in about 5% of children, there is no evidence that lowering the fever reduces the risk of febrile seizures. Trying to lower the fever quickly in this case could even trigger a seizure, says Professor Dominic Fitzgerald, a respiratory specialist at Westmead Children's Hospital in Sydney, Australia.

Medical professionals recommend using fever-reducing medication when body temperature reaches 38.5 degrees Celsius or higher and the person feels "uncomfortable and restless." However, the purpose of this is only to provide support and comfort, not to force the temperature back to normal, as a high fever is a sign that the body's immune system is working well to fight the infection.

According to Dr. Paul Young, whether or not to intervene when someone has a fever depends on their condition. For mild illnesses like the common cold, people usually feel better after about a day of fatigue. If the fever is high and accompanied by discomfort, fatigue, or pain, paracetamol can be used to lower the fever. Furthermore, if there are any unusual symptoms or if the person with the fever suddenly becomes very weak, do not hesitate to take them to a medical facility promptly.
