"That weekend, Aunt Li's Xiaoyu had a fever. Aunt Li hurriedly took out the antipyretic medicine from the medicine box and nervously monitored the thermometer. Xiao Yu's forehead was densely covered with wet towels, and the temperature in the room was adjusted higher and higher in order to 'sweat and reduce fever'. But did you know that in many cases, fever is not a bad thing, and blind medication and excessive sweating can pose additional risks. "
Fever: The body's natural warriors
Fever, often misunderstood as a sign of illness, is actually one of the body's natural defense mechanisms. When a pathogen invades, our immune system initiates the process as part of the fight against infection. Understanding this is essential for proper management of fever.
Physiological effects of fever
First and foremost, fever is part of the immune response. When a pathogen is detected in the body, such as a virus or bacteria, the immune system releases a substance called pyrogen. These substances affect our thermoregulatory center, the hypothalamus, causing the body temperature to rise. Raising body temperature helps create an environment that is not conducive to the survival of most pathogens, while accelerating the metabolic processes of cells in the body and enhancing the function of immune cells.
In addition, fever also helps to reduce the spread of pathogens in the body. Many pathogens struggle to survive or multiply at higher temperatures, so by raising their body temperature, fever can slow down their activity, giving the immune system more time to respond to the infection.
Why the fever should not be suppressed immediately
Because fever is a way for the body to fight illness, in many cases, if the fever is not particularly high (usually below 38.5°C) and the person has no other serious symptoms, immediate use of fever-reducing medications may not be the best option. Premature or inappropriate use of fever-reducing medications can interfere with the body's natural healing process and sometimes even prolong the duration of the illness.
Fever: warning or treatment?
It is crucial to understand the dual role of fever. On the one hand, it is an early warning signal from the body that some kind of infection or inflammation is occurring. On the other hand, it is the body's way of actively participating in the fight against infection. Therefore, when dealing with a mild fever, it is critical to monitor symptoms rather than rush intervention.
Alert Signs: When is a fever no longer a trivial matter?
When dealing with fever, it's crucial to distinguish between what is a self-limiting, ordinary symptom and one that might indicate a more serious health problem. Parents and caregivers need to be aware of and recognize the warning signs that indicate the need for professional medical intervention.
Persistent high fever: When to call the emergency number
A high fever that lasts for a long time (usually defined as a temperature of more than 38.5°C for more than 48 hours) can be a sign of some serious illness.
For infants and young children or children with chronic health problems, this indicator should be more stringent.
The importance of accompanying symptoms
When a fever is accompanied by symptoms such as severe headache, persistent vomiting, rash, difficulty breathing, or confusion, it is an indication of a more serious health problem.
In particular, when a fever is associated with a health problem (e.g., surgery, trauma) that has just been experienced, medical help should be sought immediately.
Changes in behavior after fever
Behavioural changes such as persistent crying, inability to soothe, or significant loss of vitality during fever may be indicative of a physical stress response.
Behavioral abnormalities may indicate disease progression to a point where it requires special attention.
Special considerations for specific populations
Children with chronic medical conditions (eg, abnormal glucose metabolism, increased blood pressure in the systemic arteries) need to be more vigilant, even if the fever is mild.
In children with weakened immune systems, such as those receiving immunosuppressive therapy, a fever can mean an emergency.
The importance of doctor's advice
Don't hesitate to consult your doctor if you experience any of the above symptoms, especially if parents are concerned about the symptoms or unsure what to do.
Your doctor may recommend further tests or treatments to rule out or treat an underlying serious condition.
Smart Medication: Proper Fever Management at Home
Fever is a common problem for parents, but knowing when and how to take medication safely is crucial. This section is designed to provide practical guidance to help parents make informed medication decisions when dealing with their child's fever.
Determine the timing of medication
Temperature standard: In general, fever reducers may be considered when your child's temperature exceeds 38.5°C. But this is not an absolute standard. Parents should observe the overall condition of their children, such as vitality and appetite.
Watch for symptoms: If your child has no serious symptoms other than a fever and can eat, drink, and play normally, medication may not be urgently needed.
Professional advice: It is advisable to consult a paediatrician before using any medication, especially for infants under 6 months of age.
Principles of safe medication
Correct dose: Follow your doctor's instructions or package insert for dosage guidance. Overdose may lead to adverse effects.
Choice of medication: Child-specific fever reducers, such as ibuprofen or acetaminophen for children, are usually recommended. Avoid adult medications or medications that are not suitable for children.
Observe the reaction: Your child should be closely observed for reaction after taking the medication. If you notice any abnormal symptoms, such as rash, difficulty breathing, etc., you should stop the drug immediately and seek medical attention.
Avoid mismedication
Risks of over-the-counter medications: Avoid self-administering antibiotics or other over-the-counter medications, which may not be appropriate for common viral fevers.
Not recommended: Avoid using multiple fever-reducing medications at the same time, which may increase the risk of side effects.
Other considerations
Stay hydrated: Make sure your child drinks enough water during a fever to prevent dehydration.
Comfortable environment: Keep the indoor temperature comfortable and avoid excessive heat.
