Prevent fever. Fever: Causes, Symptoms, and Effective Prevention Strategies
What are the common causes of fever. How can you recognize fever symptoms. What are the best ways to treat and prevent fever. When should you seek medical attention for a fever.
Understanding Fever: Definition and Normal Body Temperature
Fever, also known as hyperthermia or pyrexia, is characterized by an elevated body temperature above the normal range. While the average normal body temperature is often cited as 98.6°F (37°C), it’s important to note that this can vary slightly from person to person and fluctuate throughout the day.
Normal body temperature typically follows a pattern:
- Lower in the morning
- Higher in the late afternoon and evening
Other factors that can influence body temperature include:
- Menstrual cycle
- Intense physical activity
- Age
- Time of day
Fever Thresholds by Age Group
Different age groups have different temperature thresholds for fever:
- Infants: Above 100.4°F (38°C)
- Children: Above 99.5°F (37.5°C)
- Adults: Above 99–99.5°F (37.2–37.5°C)
The Physiological Mechanism Behind Fever
How does fever occur in the body? The process begins in the hypothalamus, a region of the brain that acts as the body’s thermostat. During a fever, the hypothalamus shifts the set point of normal body temperature upward. This triggers a series of physiological responses:
- You may feel chilled and add layers of clothing
- Shivering may occur to generate more body heat
- Blood vessels near the skin constrict to reduce heat loss
- Metabolic rate increases, producing more heat
These responses collectively result in a higher body temperature, which is the body’s natural defense mechanism against certain infections and conditions.
Common Causes of Fever: From Infections to Medications
Fever can be triggered by a wide range of factors. Understanding these causes is crucial for proper diagnosis and treatment. Here are some of the most common reasons for fever:
Infectious Causes
- Viral infections (e.g., influenza, COVID-19)
- Bacterial infections (e.g., strep throat, urinary tract infections)
- Parasitic infections (e.g., malaria)
- Fungal infections
Non-Infectious Causes
- Autoimmune disorders (e.g., rheumatoid arthritis, lupus)
- Certain medications (e.g., antibiotics, antiseizure drugs)
- Vaccinations (particularly in children)
- Heat exhaustion or heatstroke
- Hormonal imbalances
- Some cancers (e.g., lymphoma, leukemia)
It’s important to note that fever is often a symptom of an underlying condition rather than a disease itself. Identifying the root cause is essential for effective treatment.
Recognizing Fever Symptoms: Beyond Elevated Temperature
While an elevated body temperature is the primary indicator of fever, it’s often accompanied by other symptoms. Recognizing these associated symptoms can help in early detection and management of fever:
- Sweating or chills (“fever and chills”)
- Headache
- Muscle aches and weakness
- Loss of appetite
- Dehydration
- Fatigue and general malaise
- Flushed skin
- Increased heart rate and breathing rate
In children, additional symptoms may include:
- Irritability
- Lethargy
- Reduced playfulness
- Difficulty sleeping
How can you distinguish between a mild and severe fever? A mild fever (up to 101°F or 38.3°C) often doesn’t require medical attention in adults. However, high fevers (above 103°F or 39.4°C) or fevers accompanied by severe symptoms may indicate a more serious condition and should be evaluated by a healthcare professional.
Accurate Temperature Measurement: Types of Thermometers and Proper Use
Accurately measuring body temperature is crucial for diagnosing and monitoring fever. Several types of thermometers are available, each with its own advantages and proper usage techniques:
Digital Thermometers
These are the most common and versatile thermometers. They can be used for oral, rectal, or axillary (armpit) readings.
- Oral use: Place under the tongue for 3 minutes
- Axillary use: Place in the armpit, cross arms over chest, wait 4-5 minutes
- Rectal use (for infants): Gently insert about 1 inch into the rectum, hold for 3 minutes
Tympanic (Ear) Thermometers
These measure temperature by detecting infrared heat from the eardrum.
- Gently pull the ear back and insert the thermometer
- Results are usually quick, within seconds
Temporal Artery Thermometers
These measure temperature by scanning the forehead.
- Gently sweep across the forehead
- Provides quick and non-invasive readings
When selecting a thermometer, consider factors such as age of the person, ease of use, and accuracy. For infants under 3 months, rectal thermometers are often recommended for the most accurate readings.
Fever Treatment: Home Remedies and Medical Interventions
The treatment of fever depends on its severity, underlying cause, and the individual’s overall health. Here are some common approaches to managing fever:
Home Remedies
- Rest and hydration: Adequate rest allows the body to fight infection, while staying hydrated helps regulate body temperature
- Cool compresses: Applying a cool, damp cloth to the forehead can provide comfort
- Light clothing and cool environment: This helps prevent overheating
- Lukewarm baths: Can help reduce body temperature, but avoid cold baths as they can cause shivering, which raises body temperature
Over-the-Counter Medications
Antipyretics (fever-reducing medications) can help lower body temperature and alleviate discomfort:
- Acetaminophen (Tylenol)
- Ibuprofen (Advil, Motrin)
- Aspirin (for adults only; never give aspirin to children due to the risk of Reye’s syndrome)
Always follow the recommended dosage and consult a healthcare provider before giving medication to children.
Medical Interventions
For high or persistent fevers, or those accompanied by severe symptoms, medical treatment may be necessary:
- Antibiotics for bacterial infections
- Antiviral medications for certain viral infections
- Intravenous fluids for severe dehydration
- Treatment of the underlying cause (e.g., anti-inflammatory drugs for autoimmune disorders)
How long does it typically take for a fever to subside? Most fevers due to viral infections last 3 to 5 days. However, if a fever persists beyond this time or is accompanied by worrying symptoms, medical attention should be sought.
Fever Prevention: Boosting Immunity and Reducing Infection Risk
While not all fevers can be prevented, there are several strategies to reduce the risk of developing fever-causing infections and boost overall immunity:
Hygiene Practices
- Regular handwashing with soap and water
- Using hand sanitizers when soap and water aren’t available
- Avoiding close contact with sick individuals
- Covering mouth and nose when coughing or sneezing
Vaccination
Staying up-to-date with recommended vaccinations can prevent many fever-causing infections, including:
- Influenza (flu shot)
- Pneumococcal disease
- Measles, mumps, and rubella (MMR)
- COVID-19
Lifestyle Factors
Maintaining a healthy lifestyle can boost your immune system and reduce the risk of infections:
- Balanced diet rich in fruits, vegetables, and whole grains
- Regular exercise
- Adequate sleep (7-9 hours for adults)
- Stress management techniques (e.g., meditation, yoga)
- Limiting alcohol consumption and avoiding smoking
Environmental Factors
- Proper food handling and storage to prevent foodborne illnesses
- Using insect repellent in areas where mosquito-borne diseases are common
- Avoiding excessive sun exposure to prevent heat-related illnesses
What role does nutrition play in fever prevention? A well-balanced diet supports the immune system, helping the body fight off infections that could lead to fever. Key nutrients for immune health include vitamin C, vitamin D, zinc, and probiotics.
When to Seek Medical Attention: Red Flags and Emergency Situations
While many fevers can be managed at home, certain situations require prompt medical attention. Understanding these red flags can help you make informed decisions about seeking healthcare:
For Adults
Seek medical care if you experience:
- Fever above 103°F (39.4°C)
- Fever lasting more than 3 days
- Severe headache or neck stiffness
- Confusion or altered mental state
- Difficulty breathing
- Severe abdominal pain
- Persistent vomiting
- Skin rashes, especially if they’re rapidly spreading
For Children
Contact a healthcare provider if your child has:
- Fever in infants younger than 3 months (seek immediate medical care)
- Fever above 102.2°F (39°C) in children 3-12 months old
- Fever lasting more than 3 days in children of any age
- Signs of dehydration (dry mouth, no tears when crying, decreased urination)
- Unusual irritability or lethargy
- Fever accompanied by severe symptoms like difficulty breathing, abdominal pain, or rash
Emergency Situations
Call emergency services immediately if you or someone else experiences:
- Seizures
- Loss of consciousness
- Signs of sepsis (severe infection), including rapid breathing, extreme pain, or discolored skin
- Very high fever (above 105°F or 40.5°C) that doesn’t respond to medication
How can you differentiate between a fever that requires medical attention and one that can be managed at home? While the temperature itself is important, it’s crucial to consider the overall symptoms and duration of the fever. A lower-grade fever with severe symptoms may be more concerning than a higher fever with mild symptoms.
Remember, these guidelines are general, and individual circumstances may vary. When in doubt, it’s always best to consult with a healthcare professional. They can provide personalized advice based on your specific situation and medical history.
By understanding the causes, symptoms, and management strategies for fever, you can take proactive steps to maintain your health and that of your loved ones. Remember that fever is often the body’s natural defense mechanism, but knowing when to seek medical help is crucial for ensuring optimal health outcomes.

Overview
Fever is also known as hyperthermia, pyrexia, or elevated temperature. It describes a body temperature that’s higher than normal. Fever can affect children and adults.
A short-term increase in body temperature can help your body fight off illness. However, a severe fever can be a symptom of a serious condition that requires immediate medical attention.
Recognizing a fever can enable you to get treatment and proper monitoring for it. Normal body temperature is typically around 98.6°F (37°C). However, the normal body temperature for each person can vary slightly.
Normal body temperature may also fluctuate depending on the time of day. It tends to be lower in the morning and higher in the late afternoon and evening.
Other factors, such as your menstrual cycle or intense exercise, can also affect body temperature.
To check you or your child’s temperature, you can use an oral, rectal, or axillary thermometer.
An oral thermometer should be placed under the tongue for three minutes.
Shop for oral thermometers.
You may also use an oral thermometer for an axillary, or armpit, reading. Simply place the thermometer in the armpit and cross your arms or your child’s arms over the chest. Wait four to five minutes before removing the thermometer.
A rectal thermometer may be used for measuring body temperature in infants. To do this:
- Place a small amount of petroleum jelly on the bulb.
- Lay your baby on their stomach and gently insert the thermometer about 1 inch into their rectum.
- Hold the bulb and your baby still for at least three minutes.
Find a selection of rectal thermometers online.
In general, a baby has a fever when their body temperature exceeds 100.4°F (38°C). A child has a fever when their temperature exceeds 99.5°F (37.5°C). An adult has a fever when their temperature exceeds 99–99.5°F (37.2–37.5°C).
Fever occurs when a part of the brain called the hypothalamus shifts the set point of your normal body temperature upward. When this happens, you may feel chilled and add layers of clothing, or you may start shivering to generate more body heat. This eventually results in a higher body temperature.
There are numerous different conditions that can trigger a fever. Some possible causes include:
- infections, including the flu and pneumonia
- some immunizations, such as diphtheria or tetanus (in children)
- teething (in infants)
- some inflammatory diseases, including rheumatoid arthritis (RA) and Crohn’s disease
- blood clots
- extreme sunburn
- food poisoning
- some medications, including antibiotics
Depending on the cause of the fever, additional symptoms may include:
- sweating
- shivering
- headache
- muscle aches
- loss of appetite
- dehydration
- general weakness
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 (Tylenol) or ibuprofen (Advil)
- drinking plenty of fluids
Purchase acetaminophen or ibuprofen online.
A mild fever can typically be treated at home. In some cases, however, a fever can be a symptom of a serious medical condition that requires prompt treatment.
You should take your infant to a doctor if they’re:
- younger than 3 months old and have a temperature exceeding 100.4°F (38°C)
- between 3 and 6 months old, have a temperature over 102°F (38.9°C), and seem unusually irritable, lethargic, or uncomfortable
- between 6 and 24 months old and have a temperature higher than 102°F (38.9°C) that lasts longer than one day
You should take your child to see a doctor if they:
- have a body temperature exceeding 102.2°F (39°C)
- have had a fever for more than three days
- make poor eye contact with you
- seem restless or irritable
- have recently had one or more immunizations
- have a serious medical illness or a compromised immune system
- have recently been in a developing country
You should call your doctor if you:
- have a body temperature exceeding 103°F (39. 4°C)
- have had a fever for more than three days
- have a serious medical illness or a compromised immune system
- have recently been in a developing country
You or your child should also see a doctor as soon as possible if a fever is accompanied by any of the following symptoms:
- a severe headache
- throat swelling
- a skin rash, especially if the rash gets worse
- sensitivity to bright light
- a stiff neck and neck pain
- persistent vomiting
- listlessness or irritability
- abdominal pain
- pain when urinating
- muscle weakness
- trouble breathing or chest pain
- confusion
Your doctor will probably perform a physical examination and medical tests. This will help them determine the cause of the fever and an effective course of treatment.
Go to the nearest emergency room or call 911 if you or your child is experiencing any of the following:
- confusion
- an inability to walk
- trouble breathing
- chest pain
- seizures
- hallucinations
- inconsolable crying (in children)
Limiting exposure to infectious agents is one of the best ways to prevent a fever. Infectious agents often cause body temperature to rise. Here are some tips that can help reduce your exposure:
- Wash your hands often, especially before eating, after using the toilet, and after being around large numbers of people.
- Show your children how to wash their hands properly. Instruct them to cover both the front and back of each hand with soap and rinse thoroughly under warm water.
- Carry hand sanitizer or antibacterial wipes with you. They can come in handy when you don’t have access to soap and water. Find hand sanitizers and antibacterial wipes online.
- Avoid touching your nose, mouth, or eyes. Doing so makes it easier for viruses and bacteria to enter your body and cause infection.
- Cover your mouth when you cough and your nose when you sneeze. Teach your children to do the same.
- Avoid sharing cups, glasses, and eating utensils with other people.

10 Ways to Reduce Fever from a Cold or Flu │ Vicks
Do you or your loved one have a fever? The good news is you probably have nothing to worry about. Fevers are extremely common and often occur due to a virus like a cold or flu, though they’re more common in people who have the flu.1,2 They usually occur when the body is working to fight an infection in order to protect itself.3–5 As with other cold and flu symptoms, a fever is a sign that something out of the ordinary is going on in your body.
Fevers that are caused by cold viruses or flu viruses can last 3-4 days, and unfortunately, a fever—especially a high-grade fever (over 103°F)—can feel quite uncomfortable6. If you are suffering from a fever and want some relief, here are some tips for how to reduce a fever – at home or with medicine.
10 Things that Can Help to Lower a Fever
Home Remedies for Fever Symptoms
- Rest
Activity can raise your body temperature. You need to rest in order to recover and reduce a fever. For an adult whose fever is 102°F (38.9°C) or lower, the recommendation is simply to rest and drink lots of fluids. Medication isn’t always necessary. Getting enough sleep can also help to support the integrity of your immune system, so your body can fight fever-causing viruses like a cold or flu.8
Call a doctor if your fever is accompanied by a severe headache, stiff neck, shortness of breath or other unusual signs or symptoms.
- Hydration
Having a fever can cause fluid loss and dehydration. It’s important to drink plenty of fluids when you have a fever. Adequate fluid intake is often advised as part of a treatment plan for fever-inducing infections like the flu.7
- A cool environment
Keeping the room temperature cool and sleeping with only a sheet or light blanket can help keep you cooler. If your child has a fever, adjust the temperature in the house or bedroom to help keep them cool. 9
- Light clothing
When you want to break a fever, it’s also a good idea to dress in light clothing, as lighter clothing can have a cooling effect.10 It’s been reported that very warm clothing may increase a child’s body temperature even in the case that they are not ill.11
- Tepid sponging
Placing a cool, damp washcloth on your forehead and the back of your neck can help your fever symptoms feel better. You might also want to give yourself a sponge bath with cool water, focusing on high-heat areas like your armpits and groin. Normally, this method, known as tepid sponging, is done for about 5 minutes. Like staying in a cool environment and wearing light clothing, this physical measure for reducing a fever may not be as effective as fever-reducing medications.12,13
Over-the-Counter Medicines that Reduce Fever
A fever is not a pleasant symptom to experience. The chills, shivering, and headaches can become uncomfortable enough that you want relief. Keep over-the-counter medicines on hand with active ingredients that can reduce fever. Acetaminophen, for example is an over-the-counter medication that is approved for use against fever, even in children.10
Acetaminophen is a commonly used drug for reducing fever that also relieves minor aches and pains.14 But you may find that when you have a cold or flu, there are more symptoms that you need relief from, like coughing or nasal congestion.
Many over-the-counter cold and flu medicines treat multiple symptoms, including fever. Make sure to identify what other symptoms you may be experiencing along with fever, if any, so you can get the relief you need. Keep reading for Vicks products that can help reduce fever, along with other common cold and flu symptoms.
- Dayquil SEVERE
Dayquil SEVERE is a non-drowsy cold and flu symptom relief medicine for your worst cold symptoms. Along with acetaminophen to reduce fever, it also relieves chest congestion with an expectorant (guaifenesin), nasal congestion with a nasal decongestant (phenylephrine), and cough with a cough suppressant (dextromethorphan).
- Nyquil SEVERE
Fever and other cold and flu symptoms like sneezing, and cough can make it harder to sleep and get the rest you need to fight off a virus. Like DayQuil, NyQuil SEVERE has acetaminophen to reduce fever. It also has an antihistamine to help with sneezing and runny nose symptoms, and dextromethorphan to suppress your cough so you can get a good night’s sleep.
- Sinex SEVERE All-in-One Sinus LiquiCaps™
Some colds come with uncomfortable sinus symptoms—like sinus congestion, pressure, headache, and pain. That’s where Sinex comes in. Sinex SEVERE All-in-One Sinus LiquiCaps™ relieves those symptoms from the common cold or flu so you can breathe freely fast.
- FluTherapy Daytime
You’ll likely spend time resting at home if you have a cold or flu. FluTherapy Daytime comes in a soothing hot drink form, with the powerful ingredients to relieve your cold and flu symptoms while you recover at home. Dissolve the contents of one packet into 8 oz. of hot water and stir briskly. Make sure to drink the entire medicated hot drink within 10-15 minutes. FluTherapy Daytime relieves nasal congestion, sore throat, body aches, fever, and cough from a cold or flu.
- FluTherapy Nighttime
Like the daytime formula, FluTherapy Nighttime is a medicated hot drink with relief in every sip. It reduces your fever with acetaminophen and relieves other common cold and flu symptoms like runny nose. Be sure to take it at night when you’re ready to go to sleep, it will relieve your cough so you can rest and fight off the cold or flu virus causing your fever.
When to see a doctor
It is important to recognize that not all fevers are the same. While the U.S. Centers for Disease Control and Prevention (CDC) define a fever as a temperature at or above 100. 4°F (38°C), low-grade fevers that involve lower temperatures and more mild symptoms are often much less of a concern than high-grade fevers.15
While fevers can be beneficial because they can help to kill off problematic invading viruses, high fevers can be damaging to our bodies, so monitoring the level of your fever when you have one is important.4
It is generally recommended that you see a doctor if you are experiencing any of the following:16
- If your temperature reaches 104°F or higher.
- If you have fever or cough symptoms that improve, then get worse.
- If your fever is accompanied by a severe muscle pain, mental confusion, or any other out-of-the ordinary symptoms.
The fastest and most reliable way to determine if you have a fever and how significant that fever may be is to take your temperature with an easy-to-use at-home thermometer. Determining the severity of your fever can help you delineate what may be causing the fever and help you understand the best course of action to take to restore your health, and when to see your healthcare provider. 17
Fevers can occur for a variety of reasons but are often the result of a virus like a cold or flu. There are several things you can try to reduce your fever and relieve any other common symptoms. One category of these options is home remedies, such as ones that help to physically cool your body and bring your temperature down based on your external environment. Another category is over-the-counter medicines that can work by combatting fever-causing mechanisms in your body. It may also be beneficial to combine physical interventions with drugs that can help to break your fever.
Regardless of how you choose to address your fever, monitoring your fever is important for obtaining information regarding the underlying cause and severity of your condition. In cases of high or persistent fevers, or fevers accompanied by severe symptoms, you should seek medical attention.
Hopefully, you’ll now be able to reduce your fever associated with your cold or flu. For your other cold or flu symptoms, take a look at some great cold remedies and flu treatments—and get well soon!

Fever and its features in children.
Increase
temperature is the most common symptom of the disease in children, each child has at least 1 time per year
fever is noted. Temperature rise is also very common
forces the use of medicines, all feverish children receive antipyretic
means. This is facilitated by both the idea of many parents about the dangers of high temperature,
and the desire of the doctor to alleviate the discomfort associated with febrile
reaction or at least make
appointment, the effect of which will be obvious.
Wrestling
with fever is an important element of treatment, but not an end in itself, since lowering the temperature
in most cases does not affect the course of the disease. That’s why
the desire to reduce the temperature by all means and keep it at
normal level indicates
only about a weak acquaintance with the causes and significance of fever.
Fever-
an increase in body temperature that accompanies
most infectious and some non-infectious (injuries,
inflammatory, autoimmune and oncological) diseases.
Normal
the child’s body temperature fluctuates during the day from 360C to 370C.
Fever
– a defensive reaction directed against the causative agent of infection. At
t 38.50C
and above, the synthesis of interferons is enhanced,
protein synthesis, leukocytosis is stimulated. All these factors reduce the ability to
reproduction of many microorganisms. Fever suppression reduces intensity
immune response. Fever is dangerous at temperatures closer to 410
C – mainly in children from risk groups. With a high fever, metabolism increases sharply, oxygen consumption
and the release of carbon dioxide, fluid losses increase, there is
extra stress on the heart and lungs. Initially healthy child
tolerates these changes easily, although experiencing discomfort, but in children with
pathology (often the central nervous system and congenital heart defects) can
worsen the condition significantly.
Distinguish between “pink” and “white” (pale) fevers.
“Pink” fever signals the correspondence of heat production to heat transfer,
with it, the skin is pink, hot, moist to the touch, the child behaves normally. With “white”
fever, the skin is cyanotic or marbled, often appearing “goose bumps”
skin”, acrocyanosis, cold extremities.
FEVERS
Adverse
phenomena caused directly by fever are extremely rare.
The danger may be a disease that caused a fever that plays
protective role. The main danger of fever is dehydration, which is easily
prevented or corrected by the introduction of an additional amount
liquids. Violation of microcirculation, the signs of which are a marble pattern
skin, “goosebumps”, cold extremities, observed with “white” fever and
require restoration of microcirculation. Fever is not harmful
actions on the CNS.
K
dangers of fever include the possibility of developing febrile seizures, which
observed in 2-4% of those predisposed to
children, more often at the age of 12-18 months and do not have an unfavorable
influence on the central nervous system and its development.
In general, the hazards associated with
fever, are largely exaggerated, with most infections the maximum
temperature is set within 39.5-40.00 C, which does not threaten
persistent health problems.
in a child always indicates a disease, but its severity, as
usually does not correlate with its severity. Many common viral
(eg, rhinitis, sinusitis, pharyngitis, pneumonia) and bacterial (otitis media,
urinary tract infection, impetigo) infections in immunocompetent individuals do not
have a severe course, against the background of antibiotic therapy or symptomatic
treatment, recovery is fast. Other infections (sepsis, meningitis, pneumonia,
purulent infections of bones and joints, pyelonephritis) without treatment often lead to
complications and sometimes even death. Most febrile
diseases in children is associated with viral infections and those bacterial,
which only briefly violate the health and do not pose a threat to the life of the child.
.Fever
in a child under the age of 3 months of life requires close monitoring due to
high risk of developing a serious bacterial infection.
“White (pale)” fever requires
restoration of microcirculation.
Fever
without catarrhal phenomena, rash and other visible local symptoms of infection
common with urinary tract infection, in children 0-3 years of age may indicate the development
bacteremia.
Preservation
febrile fever (more than 38.5 C) for more than 3 days, especially with rapid breathing
(including in the absence of catarrhal phenomena) may indicate
development of pneumonia.
Hemorrhagic
a rash (not blanching on pressure) with fever may indicate meningococcemia – in this case, emergency therapy is required.
Rigidity
occipital muscles or their soreness, bulging of the fontanel on the background of fever
indicates a CNS infection (meningitis).
Fever associated with abdominal pain and vomiting
requires exclusion of appendicitis.
Fever
with joint pain may be associated with bacterial arthritis, osteomyelitis.
Resistant
fever with rash, changes in the oral mucosa, scleritis,
an increase in lymph nodes requires the exclusion of Kawasaki disease.
(more than 2 weeks) fever requires examination to detect long-term
ongoing infections, connective tissue diseases, immunodeficiency,
oncological pathology.
TREATMENT
FEVER
Fever
is not an absolute indication for temperature reduction.
In cases where the reduction
temperature is necessary, there is no need to strive to bring it to normal – enough
decrease by 1-1.50С.
to decrease in temperature:
In previously healthy children older than
3 months:
– at body temperature above 39.00C -39.50C; and / or
– in the presence of a muscular or head
pain;
– in shock.
In children under 3 months of age:
– at body temperature above 380C.
In children with diseases of the heart, lungs,
CNS:
– at body temperature above 38.50C.
Uncontrolled
the use of antipyretics, especially “course”, creates the illusion
well-being and causes a belated appointment of etiotropic drugs.
Selection
antipyretics should be founded,
first of all, on their safety, and not on the strength of the effect. Ideally, an antipyretic drug for children should have
the ability to quickly and effectively reduce the temperature by at least 10C,
available in liquid form and as suppositories, rarely cause side effects
effects at therapeutic doses and have as wide a gap as possible between
therapeutic and toxic dose.
This
only two drugs, paracetamol and ibuprofen, currently meet this parameter.
B
pediatric practice prohibited the use of acetylsalicylic acid and nimesulide.
REFERENCE
FOR PARENTS
*temperature – protective reaction; her
should be reduced only according to the indications given above;
*adequate fluid administration
a feverish child is more important than a decrease in his temperature;
*not important in antipyretics
“strength”, but safety, to improve the patient’s condition, it is enough to reduce
temperature by 1-1. 50C;
* Paracetamol and ibuprofen are the most
safe drugs, it is important to adhere to the recommended one-time and daily
their dosages;
*do not prescribe antipyretic “course”
to prevent a rise in temperature, because you can see the progress
bacterial infection;
*do not use for the same reason
antipyretic drugs for longer than 3 days without consulting a doctor;
*with the development of “pale” fever with
spasm of the skin vessels, the introduction of an antipyretic agent should be combined with
vigorously rubbing the baby’s skin
until redness and immediately call a doctor.

Baby fever: what is it?
Childhood fever is an elevated body temperature in a child, often accompanied by other symptoms such as headache, chills, muscle aches and decreased appetite.
An increase in body temperature is part of the body’s defense response to infection or inflammation. As a rule, this is due to the activation of the immune system, which fights the causative agent of the disease.
However, high fever can also be caused by other causes such as fluid loss, an allergic reaction, and other illnesses.
Causes of infantile fever
infections are the most common cause of infantile fever. They can be caused by viruses, bacteria, or parasites. Such infections include SARS, influenza, whooping cough, malaria and other diseases.
Complications of surgery – Children, especially infants, may develop a fever after surgery. This is due to infectious complications or a reaction to anesthesia.
Vaccination – an adequate immune response to vaccines may be accompanied by fever. This reaction is usually of short duration and does not require treatment.
Allergic reactions – These include allergies to a specific food source, drugs, vegetation, and chemicals. Allergies can cause fever along with other symptoms.
General fatigue of the body – fever can be caused by severe physical or emotional stress. Children who overwork may fall into a state that leads to a rise in temperature.

How to help a child with childhood fever?
1. Maintain the correct drinking regimen: if the child’s body temperature is elevated, he will lose fluid faster. So don’t forget to offer him water or other drinks that can help keep him hydrated. Limit the amount of sugar and caffeine, as they can aggravate the condition.
2. Maintain a comfortable temperature: the child must remain in a comfortable temperature zone. If the room temperature is too high, open the windows or turn on the air conditioner. If the child is cold, have him put on warm clothes or cover himself with a warm blanket.
3. Apply cooling methods: To reduce body temperature, use cooling methods such as rubbing the body with water (including adding vinegar), applying wet compresses to the forehead or armpits, enriching the water with a humidifier in the room. But do not use ice water or ice, as this can lead to frostbite.
4. Give your child medicine: There are various antipyretic and anti-inflammatory medicines that can help manage a child’s fever. But remember to follow the dosage and do not give your child aspirin under 16, as this can increase the risk of Flight Syndrome.
5. Monitor the child: monitor the child’s condition and behavior. If you see new symptoms appear, see your doctor.
Why do children get fever more often than adults?
Probably many parents have asked themselves this question when they saw that another of their children had a fever. Why are children, especially younger ones, so prone to this problem?
Immunity: In young children, immunity is still weak and not fully developed. The child’s body does not have enough antibodies to fight infection, making it more vulnerable to various viruses and bacteria.
Contact with a large number of people: Children visit kindergartens, schools, playgrounds, where they can meet other children with various infections. This can cause infection in the child, especially when the immune system is not strong enough to cope with the infection.
Increased activity: Children are more active and love to play, run and jump. Their active lifestyle can lead to damage and injury, which in turn can cause various inflammatory processes and an increase in body temperature.
It is important to remember that childhood fever is a serious illness that requires medical attention. If your child has signs of a fever, be sure to see a doctor so that he can determine the cause of the illness and prescribe the correct treatment.
