What temperature is considered a fever in adults and children. How does the body regulate temperature. When should you seek medical attention for a fever. What are effective methods for lowering a fever at home. How can you distinguish between dangerous and mild fevers.

Understanding Body Temperature and Fever

The human body typically maintains an average temperature of 98.6°F (37°C), with normal fluctuations between 97.7°F (36.5°C) and 99.5°F (37.5°C) throughout the day. A temperature above 99.5°F is generally considered a fever in both adults and children. But what causes these temperature changes, and when should we be concerned?

Fever is not an illness itself, but rather a symptom of an underlying condition. It often indicates that the body is fighting off an infection or other health issues. The immune system raises the body temperature as part of its defense mechanism against invading pathogens.

Common Causes of Fever

• Viral infections (flu, common cold)
• Bacterial infections (pneumonia, urinary tract infections)
• Heatstroke
• Inflammatory conditions (rheumatoid arthritis, inflammatory bowel disease)
• Certain medications or vaccinations
• Hormonal disorders
• Cancer
• Autoimmune diseases

The Body’s Temperature Regulation Mechanisms

Our bodies have sophisticated systems in place to maintain optimal temperature. Several organs play crucial roles in this process, including the skin, brain, muscles, and blood vessels. When the body needs to cool down, it employs various strategies:

1. Increased sweat production to cool the skin
2. Blood flow redirection to or from the skin’s surface
3. Behavioral changes, such as seeking a cooler environment
4. Water retention or release through sweat glands and the urinary system

It’s important to note that factors other than illness can influence body temperature. These include heavy clothing, physical exertion, strong emotions, high heat and humidity, menstruation, and certain medications.

Recognizing Dangerous Fever Levels

While a mild fever is often beneficial and helps the body fight infections, high fevers can be dangerous. But how high is too high? The answer depends on various factors, including age and overall health.

Fever Danger Levels by Age

• Infants 0-3 months: Any fever above 100.4°F (38°C) requires immediate medical attention
• Infants 3-6 months: Fever above 102°F (38.9°C) warrants a call to the doctor
• Children 6 months to 2 years: Fever persisting for more than 24 hours or rising above 102°F (38.9°C)
• Children 2 years and older: Fever above 103°F (39.4°C) or lasting more than 3 days
• Adults: Fever above 103°F (39.4°C) or lasting more than 3 days

Is a high fever always dangerous? Not necessarily. The body’s response to the underlying cause is often more important than the temperature itself. However, very high fevers (above 104°F or 40°C) can lead to complications such as dehydration, confusion, or seizures, especially in children.

When to Seek Medical Attention for a Fever

While many fevers can be managed at home, certain situations require professional medical evaluation. When should you consult a doctor for a fever?

• The fever is accompanied by severe symptoms such as difficulty breathing, chest pain, or severe headache
• There are signs of dehydration, including dry mouth, sunken eyes, or decreased urine output
• The person experiences confusion, lethargy, or seizures
• The fever persists for more than three days
• There’s a recent history of travel to areas with endemic diseases
• The person has a weakened immune system or chronic medical conditions
• In infants younger than 3 months, any fever should be evaluated by a healthcare provider

Are there specific symptoms that indicate a fever is more serious? Yes, if a fever is accompanied by severe headache, stiff neck, persistent vomiting, or a widespread rash, it could indicate a more serious condition requiring immediate medical attention.

Effective Methods for Lowering a Fever at Home

While it’s often best to let a mild fever run its course, there are times when you may want to lower the temperature for comfort. What are some safe and effective ways to reduce a fever at home?

1. Stay hydrated: Drink plenty of fluids, especially those containing electrolytes
2. Rest: Allow your body to conserve energy for fighting the infection
3. Dress lightly: Wear breathable, lightweight clothing
4. Keep the room cool: Maintain a comfortable room temperature
5. Use a cool compress: Apply a damp cloth to the forehead, wrists, or back of the neck
6. Take a lukewarm bath: This can help lower body temperature gradually
7. Use over-the-counter medications: Acetaminophen or ibuprofen can help reduce fever, but always follow dosage instructions carefully

Should you use cold baths or alcohol rubs to lower a fever? No, these methods are not recommended as they can cause shivering, which actually raises body temperature. Instead, opt for lukewarm baths or cool compresses.

The Role of Fever in Fighting Infections

While fever can be uncomfortable, it plays a crucial role in the body’s defense against pathogens. How does fever help combat infections?

• Increases metabolic rate, enhancing immune system function
• Creates an inhospitable environment for many pathogens
• Stimulates the production of white blood cells and antibodies
• Enhances the effectiveness of certain immune system proteins

Does this mean you should never treat a fever? Not necessarily. While low-grade fevers can be beneficial, higher temperatures can cause discomfort and potentially lead to complications. The goal of fever management is often to improve comfort rather than to eliminate the fever entirely.

Fever in Special Populations: Children, Elderly, and Immunocompromised

Fever can affect different populations in varying ways. How does fever management differ for children, the elderly, and those with compromised immune systems?

Children and Fever

Children often experience higher fevers than adults due to their more reactive immune systems. Febrile seizures, while frightening, are generally not harmful and occur in about 2-5% of children under 5 years old. However, any fever in infants under 3 months should be evaluated by a healthcare provider.

Elderly and Fever

Older adults may not develop fever as readily as younger individuals. A slight increase in temperature or other symptoms like confusion or weakness may be the only signs of infection. Therefore, any change in an elderly person’s condition should be taken seriously.

Immunocompromised Individuals and Fever

People with weakened immune systems, such as those undergoing chemotherapy or with HIV/AIDS, may not develop typical fever responses. Any elevation in temperature in these individuals should be evaluated promptly by a healthcare provider.

How does fever presentation differ in these groups? In children, fevers can spike quickly and cause alarming symptoms like febrile seizures. Elderly individuals might not develop high fevers even with serious infections. Immunocompromised people may have atypical fever patterns or lack fever entirely despite having infections.

Understanding Fever Patterns and Their Significance

Fever patterns can provide valuable information about the underlying cause. What are some common fever patterns and what do they indicate?

• Continuous fever: Temperature remains above normal throughout the day and doesn’t fluctuate more than 1°C. This pattern is common in lobar pneumonia.
• Intermittent fever: The temperature returns to normal between fever spikes, often seen in malaria.
• Remittent fever: Temperature fluctuates but never returns to normal, common in infective endocarditis.
• Relapsing fever: Fever-free periods are followed by days of fever, seen in conditions like rat-bite fever.

Can fever patterns help diagnose specific conditions? While fever patterns can provide clues, they are not definitive for diagnosis. Other symptoms and diagnostic tests are usually necessary to determine the underlying cause accurately.

The Impact of Fever on the Body

While fever is a natural defense mechanism, it can have various effects on the body. What are some of the physiological changes that occur during a fever?

1. Increased heart rate and respiratory rate
2. Elevated metabolic rate, leading to increased calorie burn
3. Decreased appetite
4. Fatigue and muscle aches
5. Increased fluid loss through sweating
6. Potential cognitive effects, such as confusion or irritability

How does prolonged fever affect the body? Extended periods of high fever can lead to dehydration, electrolyte imbalances, and in severe cases, organ damage. This is why monitoring and managing high fevers is crucial, especially in vulnerable populations.

Myths and Misconceptions About Fever

There are many common beliefs about fever that are not supported by scientific evidence. What are some prevalent myths about fever and the truth behind them?

• Myth: Fever is always harmful and must be treated aggressively.
• Truth: Mild to moderate fevers are often beneficial and help fight infections.

• Myth: The height of a fever always indicates the severity of an illness.
• Truth: The overall condition of the person is more important than the temperature alone.

• Myth: Fevers can cause brain damage.
• Truth: Typical fevers (under 104°F or 40°C) do not cause brain damage. Only extremely high temperatures, usually associated with heat stroke, can potentially harm the brain.

• Myth: Bundling up helps “sweat out” a fever.
• Truth: Excessive bundling can actually increase body temperature and discomfort.

Do these myths affect how people manage fevers? Unfortunately, yes. These misconceptions can lead to overtreatment of mild fevers or unnecessary anxiety. It’s important to understand that fever is typically a helpful immune response rather than a condition that always requires intervention.

The Future of Fever Management: Emerging Research and Technologies

As our understanding of fever and its role in the immune response grows, new approaches to fever management are emerging. What are some promising areas of research in fever treatment?

• Targeted antipyretic drugs that modulate specific fever pathways without suppressing beneficial immune responses
• Advanced wearable technologies for continuous temperature monitoring and early detection of fever patterns
• AI-powered diagnostic tools that analyze fever patterns along with other symptoms to predict underlying causes
• Immunomodulatory therapies that enhance the body’s natural fever response in certain conditions

How might these advancements change our approach to fever management? These developments could lead to more personalized and precise fever management strategies, potentially improving outcomes in various infectious and inflammatory conditions. However, it’s important to note that these technologies are still in development and require further research before widespread clinical application.

Fever in the Context of Global Health

Fever remains a significant health concern globally, particularly in regions with limited access to healthcare. How does fever impact public health on a global scale?

• Fever is a common presenting symptom in many endemic infectious diseases, such as malaria, dengue, and typhoid fever
• In resource-limited settings, distinguishing between different causes of fever can be challenging, leading to potential misdiagnosis or overuse of antibiotics
• Climate change may be altering the geographic distribution of fever-causing diseases, presenting new challenges for global health systems
• The COVID-19 pandemic has highlighted the importance of fever screening in public health responses to infectious disease outbreaks

What strategies are being employed to address fever-related health issues globally? Efforts include improving access to diagnostic tools, developing better fever management protocols for resource-limited settings, and implementing community-based fever surveillance programs. Additionally, global health initiatives are focusing on prevention strategies, such as vector control for mosquito-borne diseases and improved sanitation to reduce the incidence of fever-causing infections.

Conclusion: A Balanced Approach to Fever Management

Understanding fever and its implications is crucial for appropriate health management. While fever can be a sign of serious illness, it’s often a beneficial immune response that helps the body fight infections. The key is to recognize when a fever requires medical attention and when it can be managed at home.

Remember these key points about fever:

• Not all fevers require treatment; mild fevers often resolve on their own
• The overall condition of the person is more important than the temperature alone
• Proper hydration is crucial during a fever
• Certain populations, such as infants and immunocompromised individuals, require closer monitoring
• If in doubt, consult with a healthcare provider

By taking a balanced approach to fever management, we can support our body’s natural defense mechanisms while ensuring safety and comfort. As research continues to advance our understanding of fever, we can look forward to even more effective and personalized approaches to managing this common but complex symptom.

When Fevers Get Dangerous | iCare

Having a fever doesn’t necessarily mean that you need to visit a doctor. In fact, a fever can be a good sign because it shows that your body is fighting an illness or infection. A low-grade fever is an essential part of the immune response, and you will often feel better in a few days.

Why Does Fever Occur?

A fever isn’t an illness – it is a symptom of another health condition. Usually, the body develops a fever in response to an infection that is occurring. The illness or disease is detected, then the immune system kicks into gear to fight the virus or bacteria. This response stimulates the body’s defenses, sending out the white blood cells that are needed for protection. Fever can be caused by a variety of conditions, including:

• Flu
• Common cold
• Heatstroke
• Ear infections
• Pneumonia
• Sinus infection
• Internal infection
• Skin infection
• Bronchitis
• Urinary tract infections
• Blood clots
• Appendicitis
• Autoimmune diseases
• Rheumatoid arthritis
• Inflammatory bowel disease
• Cancer
• Hormone disorders
• Illegal drugs

Sometimes, fever is a temporary response to a specific cause. For example, young children often have a fever when teething or for a day or two after immunizations.

How Body Temperature Works

The average body temperature is 98.6 degrees F, but it is normal for the temperature to range between 97.7 degrees F and 99.5 degrees F throughout the day. For example, it is common for the body temperature to be higher in the evening compared to the morning. If the temperature goes above 99.5 degrees F, then it is considered a fever in both adults and children.

The body has built-in systems to maintain normal body temperature. Several organs affect temperature regulation, including the skin, brain, muscles, and blood vessels. If the body needs to cool down, then a few responses might occur:

• Sweat production increases to cool the skin
• Blood is moved closer to, or away from, the surface of the skin
• You feel the urge to move to a cooler environment
• Water in the body is retained or released through the sweat glands and urinary system

A fever is not the only factor that can increase body temperature. Heavy clothing, physical exertion, strong emotions, high heat and humidity, menstruation, and certain medications can increase body temperature. When you are taking a person’s temperature, check to ensure these other factors aren’t influencing the thermometer reading. For example, if a child has been running around, have them sit still for 20 minutes before using the thermometer to ensure you are getting an accurate reading.

Tips for Lowering a Fever

Just because a person has a mild fever, doesn’t mean that you need to be proactive in lowering the fever. Often, the best solution is to let the fever run its course by resting at home and staying hydrated. If you notice that the fever is increasing in severity, then these are a few things that can be done at home to see if the fever can be managed without medical treatment:

• Take a lukewarm bath (not cold water)
• Place a cool washcloth on the forehead
• Use over-the-counter acetaminophen, according to dosage directions on the package. Choose children’s brand medication for young members of your family.
• Adjust the thermostat in the house
• Remove blankets and heavy clothing
• Drink plenty of fluids, especially drinks with electrolytes to counteract the minerals lost through sweating

Even though ice baths and alcohol rubs are sometimes recommended as DIY fever treatments, these at-home methods should be avoided. Ice and alcohol rubs cause the body to shiver, which increases the internal temperature even more.

The main benefit of lowering a fever is to help the person be more comfortable, especially when they are trying to sleep at night. Additionally, body temperature regulation is essential to avoid potentially dangerous side-effects, such as seizures.

When is a Fever Dangerous?

A mild fever isn’t considered dangerous. If you or a family member has a low-grade fever with other common illness symptoms, then a few days of rest and healing at home might be just what the doctor ordered. But how do you know when it is time to seek medical attention? If the fever escalates, then it could potentially become dangerous.

These are a few signs that indicate you should seek medical attention immediately. Talk to the doctor if the fever is accompanied by:

• Bruising
• Rashes
• Difficulty breathing

Other signs that you need medical attention might include:

• You’ve recently received one or more vaccinations
• You visited another country recently
• You have a serious pre-existing condition
• A child seems confused or delirious
• A child won’t stop crying
• The person has a weakened immune system or other medical complications

Fevers in Children vs. Adults

One determining factor regarding whether medical care is needed is based on the severity of the fever and the age of the person. You should talk to a doctor when these criteria are met:

• 0 – 3 Months Old: The child has a rectal temperature at or above 100. 4 degrees F
• 3 – 12 Months Old: An oral temperature reading is at or above 102.2 degrees F
• 2 Years Old – Teenage Years: If the child’s fever lasts more than 24 – 48 hours
• Adults: If the fever is above 103 degrees F and lasts more than 48 hours. Any time an adult fever reaches 105 or more, talk to a doctor right away.

Medical Treatment for Fever

Since a fever is a symptom of an underlying condition, it is important to obtain an accurate diagnosis to determine the best treatment plan. For example, antibiotics might be recommended for a bacterial infection, such as an ear infection or strep throat.

If you need medical care right away, then visiting an Urgent Care might be the most effective solution. At our clinic, you don’t have to schedule an appointment or wait for an opening. Walk-ins are welcome! Your entire family has access to fast treatment for a variety of injuries and illnesses.

How To Know If You Should Go To The ER For A Fever

If you are otherwise healthy and alert, having a low-grade fever may not necessarily be cause for concern. However, an elevated temperature can be indicative of another process or illness that needs to be treated. A severe or prolonged fever can even cause complications on its own. Because there are a number of possible causes of fever, many of which trigger a similar set of symptoms, it can be challenging to self-diagnose your condition. The expert team of board-certified physicians at both of iCare ER & Urgent Care’s convenient locations in Frisco and Fort Worth, TX provides prompt and reliable evaluation, diagnosis, and treatment for patients presenting with fever. Find out more about the possible causes of fever here, and learn what situations may warrant a visit to the ER for fever.

What is a fever?

For most adults, a normal body temperature is between 97°F and 99°F, though 98.6°F is generally accepted as the standard of normal. When a patient’s body temperature becomes elevated to 100.4°F or higher, he or she is considered to have a fever. Oftentimes, a fever indicates that the body is fighting off a virus, infection, or another pathogen. Common symptoms of a fever include:

• Sweating
• Chills
• Headache
• Body aches
• Fatigue
• Loss of appetite

What causes a fever?

There are a variety of potential reasons why a person’s body temperature may become elevated, either temporarily or for several days or weeks. Some of the most common causes of a fever include:

• Virus
• Infection
• Cold and/or flu
• Stomach bug
• Recent vaccination
• Heat exhaustion

How long does a fever last?

Depending on the cause of the fever, the patient’s overall health, what treatments are given, and other factors, a fever can last anywhere from several hours to several weeks. For some of the most common illnesses, such as the flu, most people demonstrate an elevated temperature for about 2 – 4 days.

How high is too high for a fever?

Fever of 103°F or above is considered high grade and should be treated immediately. However, even a low-grade fever may be a sign of a dangerous problem for infants and babies. If you are concerned about fever in your infant, your child, or yourself, visit your nearest Fort Worth or Frisco emergency room within iCare ER & Urgent Care’s unique dual-hybrid facility.

When should you go to the ER for a fever?

For patients who are otherwise healthy, alert, and have an obvious explanation for their low-grade fever – such as a cold – at-home remedies and monitoring may be sufficient. However, any fever above 103°F should be treated immediately in the ER. In addition, if you or your child are experiencing any of the following symptoms in conjunction with a fever, a trip to the ER is warranted:

• Confusion
• Severe pain (abdominal pain, headache, muscle pain, etc. )
• Sensitivity to light
• Skin rash or irritation
• Protracted nausea or vomiting
• Inability to eat or drink
• Difficulty breathing
• Chest pain

Fever ✅ Information for Patients from Experts Sanmedekspert

Fever in a child or adult is always a serious cause for concern. Why it appears when you need to urgently see a doctor, and when you don’t need to knock it down, how to properly reduce it at home – these and many other questions are answered by experienced specialists of our clinic.

The most optimal temperature for biochemical processes in the human body is from 36.5 to 37.2°C. If the thermometer shows deviations of 1 – 1.5 ° C up or down, then it means that the body has failed. An elevated temperature is called up to 39°С, and high – from 39°С.

Types of temperature:

• Norm – from 35°С to 37°С. This indicator directly depends on many factors: time of measurement, gender, age of the person.
• In case of hyperthermia, the temperature is above 37°C. This condition is due to a violation of the mechanisms of thermoregulation: an excess of heat from outside or, conversely, difficult heat transfer. For example, clothes that are too warm, heat stroke, sunstroke, burns, physical activity, etc.
• Fever (fever) is a protective reaction of the body to the appearance of foreign agents in it:

1. fungal infection,
2. viruses,
3. bacteria,
4. pathological process – for example, damage to the nervous system, hemorrhage, inflammation, trauma, etc.

In fever, thermoregulatory mechanisms are preserved. There are mild fever (38 – 38.5 ° C), moderate (38.6 – 39.5 ° C) and high (above 39.5 ° C). Temperatures above 40.5 – 41°C are a serious danger to life.

Causes of fever

• Colds.
• Viral and bacterial infections.
• Rheumatism.
• Inflammatory processes in the internal organs.
• Eruption of milk teeth in children.
• Overeating.
• Physical overload.
• Period before menses in women, etc.

Is it true that fever is good for you?

Light heat activates the body’s defenses. As soon as the “invasion of the enemy” occurs, all organs begin to release pyrogen proteins into the blood. They, in turn, trigger an increase in temperature and the production of antibodies and interferon protein, which kill harmful microorganisms. By artificially lowering the temperature with drugs, we interfere with the immune system to fight the infection.

It has been proven that at a temperature of 38 – 38.5°C the following processes occur in the body:

• the production of antibodies to the pathogen and interferon increases;
• significantly slows down the reproduction of viruses and bacteria;
• the liver more effectively neutralizes toxic waste products of pathogenic microorganisms, and the kidneys excrete them faster with urine;
• there is an increased activity of enzymes;
• bactericidal properties of blood serum and lymph increase.

A slight fever, although unpleasant in its symptoms, helps to recover faster. By knocking it down, we expose ourselves to even greater danger. After taking an antipyretic, a person will, of course, feel much better, but an undefeated infection will remain inside, continue to spread quietly throughout the body and can provoke serious complications to the kidneys, such as pyelonephritis or cystitis.

How to help the body with a fever?

• Do not raise the temperature artificially.

Do not take a hot bath, do not steam your feet, do not put mustard plasters and alcohol compresses, do not drink alcohol, hot milk, tea, coffee, do not wrap yourself in blankets.

• Drink plenty of fluids.

Drink should be plentiful and warm, it can be at room temperature, and always unsweetened. Best of all – mineral water with lemon, lingonberry or cranberry juice. The blood becomes more liquid, toxic substances are excreted faster, the body does not suffer from dehydration. Sugary drinks are dangerous because water will come out with sweat, and glucose will become an additional food source for pathogens.

• Sweat properly and stay in bed

Intense sweating is a natural thermoregulatory mechanism during fever. Evaporating from the skin, sweat cools the body and prevents it from overheating. Wrapping the patient in several blankets and insulated pajamas, we prevent the sweat from evaporating. A person with a fever should be dressed in cotton clothing and lie under a light, thin blanket. Linen should be changed as it gets wet.

• Cleanliness and fresh air.

The room must be clean and well ventilated. As a rule, a sick person breathes through his mouth, which means that, together with moist, stale air, an infection will quickly penetrate into his lungs. The air temperature in the room should be approximately 22°C – 24°C. It is extremely important that there are no drafts.

• Do not wipe your body with vodka or alcohol.

Alcohol vapors evaporate very quickly and cause severe hypothermia and severe chills. It is best to wipe the body with a sponge dipped in warm water, or put the patient in a cool bath for a while.

• Food should be light

All fried, salty, fatty, spicy foods and alcohol should be excluded from the diet during illness. The best choice is low-fat broths, juices, fruit drinks, fresh and boiled fruits, vegetables.

How to bring down the temperature correctly and in what cases should it be done?

You need to start lowering the temperature if it is above 38-38.5°C, lasts more than 3-5 days or the thermometer approaches 40°C. You can do this in the following ways:

• the patient should drink plenty of warm, unsweetened liquids;
• cold compresses applied to the forehead, neck, wrist, armpits and groin areas, as well as cool foot baths and wet sheet wraps, work well;
• wiping should be done as follows: moisten a towel in warm water, first wipe your face with it, and then hands, body and legs;
• A cooling bath will help reduce the temperature and flush out toxins. First, the patient is placed in a warm bath, then cold water is gradually added to it up to a temperature of 30 ° C;
• Antibiotics can only be prescribed by a doctor. Before his arrival, you need to take antipyretics.

When do you need to urgently call an ambulance?

• The thermometer shows above 39.5°C.
• Fever is accompanied by abdominal pain (especially in the elderly and children), vomiting, weakness, limited movement, visual disturbances, or severe neck muscle tension (the person cannot tilt the chin to the chest).
• Children under the age of 10 have a very dry, barking cough. In combination with temperature, this symptom indicates an inflammatory narrowing of the larynx (false croup).
• If the temperature rises above 38°C very quickly, within 1-2 hours. This is especially dangerous if a child under 6 years of age is sick, and he has already experienced convulsions during heat – in this case, even a small temperature of 37. 5 ° C is fraught with serious consequences.
• Mild fever is dangerous for people with convulsive readiness and cardiovascular disease.

If fever is accompanied by weakness, pain in the joints and muscles, blurred vision, consciousness, headache, convulsions, shortness of breath, you should immediately consult a doctor. Also, be sure to make an appointment if you have a slightly elevated temperature for more than 7 days.

An increase in body temperature (hyperthermia) is a protective reaction of the body to the penetration of viruses, bacteria, the development of an inflammatory process ^1.2 . In this state, it is recommended to keep bed or semi-bed rest, not to overcool and follow all medical recommendations ³ . Hyperthermia can occur suddenly, against the background of minor external manifestations. And many people just don’t know what to do at 393 ° C, so as not to harm your health and not aggravate your situation. The main thing is not to panic. If the temperature on the thermometer is 39.3 ° C, then you need to contact a specialist as soon as possible. Self-medication can lead to serious complications.

Viral infections. Viruses are the most common cause of fever up to 39.3°C. Diseases caused by such pathogens, in most cases, occur with high body temperature, runny nose, cough, chills, muscle aches, which occurs in response to the release of toxins by microorganisms that actively multiply in the body of an adult during the development of acute respiratory infections, influenza, parainfluenza and other similar diseases ^3,4,5 .

Exacerbation of chronic ENT diseases and respiratory pathologies. Diseases such as laryngitis, tonsillitis, sinusitis, bronchitis, in a chronic form, can often recur against the background of hypothermia or the development of respiratory viral diseases ^3.5 .

Intestinal infections. A temperature of 39.3 °C in an adult may occur against the background of active reproduction of infectious pathogens affecting the gastrointestinal tract ^3.4 . In this case, hyperthermia is accompanied by diarrhea, abdominal pain, and vomiting is also possible.

Inflammation of the joints. In adults, high body temperature is often diagnosed against the background of exacerbation of arthritis and other diseases of the articular tissues. Patients complain of general malaise, muscle pain, limited mobility in the diseased joint. The skin over it turns red and becomes hot to the touch ⁴ .

Causes of fever up to 39.

3 °C in children

An increase in a child’s temperature to 39.3 °C or more frightens parents who do not know what to do and how to deal with such a condition. It is important to understand that hyperthermia in childhood can lead to dangerous complications, up to respiratory arrest ² . Therefore, in no case should you self-medicate, but you should show the child to a qualified specialist. The doctor will conduct an examination, prescribe laboratory tests and other diagnostic methods, the results of which can make an accurate diagnosis and select an effective treatment.

Common causes of fever above 39 °C in childhood:

• flu. The disease is based on a viral infection, which is accompanied not only by hyperthermia, but also by severe headaches, muscle aches, and in young children often also nausea and vomiting;
• rhinovirus infection. It occurs against the background of an acute respiratory disease provoked by a rhinovirus, which causes a severe runny nose, nasal congestion and short-term fever with fever;
• intestinal flu (rotavirus infection). The causative agent is rotavirus, which causes symptoms of enteritis and gastroenteritis, damages the cells of the small intestine, causing vomiting and diarrhea in the child;
• ENT diseases. In childhood, viral infections are often complicated by laryngitis, sinusitis, otitis media, causing a temperature rise above 39 ° C;
• overheating of the body or prolonged crying sometimes causes a short-term increase in body temperature in young children;
• Teething can also cause high body temperature, and hyperthermia occurs not only in infants, but also in preschoolers and schoolchildren when changing milk teeth to permanent ones ^1,2,3 .

What should I do if the temperature

39.3 °C does not pass for a long time?

Why is 39.3°C dangerous?

Temperatures above 39°C are dangerous for both children and adults ^1.2 . It can lead to irreversible consequences in the central nervous system, dehydration of the body and disruption of the cardiovascular system ^{1. 2} . Against the background of hyperthermia, blood viscosity often increases, which can provoke thrombus formation ² .

A high body temperature is especially dangerous for a child. Children, due to their age and mental characteristics, cannot clearly talk about their feelings. If a child is sick, he needs to measure his body temperature several times a day so as not to miss its sharp increase. Against the background of severe hyperthermia in childhood, convulsions and respiratory disorders often occur ^1,2,5 . In such cases, it is obligatory to take special children’s antipyretics approved for a child of a certain age ^1.5 .

The temperature of 39.3 °C must be brought down

Experts recommend not to bring down the body temperature if it is below 38 °C in children and below 38.3 °C in adults ² . But it must be taken into account that each organism is individual, and if the state of health worsens against the background of even a slight hyperthermia (up to 38 ° C), then, as prescribed by a specialist, it is worth taking an antipyretic agent that has a complex effect, including reducing muscle aches and headache ³ .

Children have a particularly hard time with high body temperature. Against the background of hyperthermia, they may experience vomiting and diarrhea, severely reduced appetite and disturbed sleep ⁵ . Experiments with drugs in childhood can be a direct threat to the child’s life. Medicines should be prescribed by a pediatrician.

Temperature of 39.3 °C without symptoms: possible causes

The appearance of a high body temperature without symptoms of a specific disease is very frightening and confusing. If such a condition recurs periodically, it is necessary to undergo a comprehensive diagnosis of the body as soon as possible in order to find out the true causes of hyperthermia ^4.5 .

Infectious diseases at an early stage can sometimes be accompanied by only an increase in body temperature – without other symptoms. Additional symptoms appear later, after a few days. You may feel slightly unwell and your body temperature rises above 38°C. And only after 1-2 days there are such symptoms as a runny nose, nasal congestion, cough, redness of the throat ³ .

Some chronic diseases are almost asymptomatic, against the background of a short-term increase in body temperature ⁴ . To make an accurate diagnosis and prescribe treatment, it is necessary to conduct an examination and obtain test results. The person himself may not notice the manifestations of viral or bacterial infections, requiring not only the intake of antipyretics, but also other medications.

An increase in body temperature without symptoms of a viral infection is possible in childhood during teething. The child tries to scratch his gums, is naughty, sleeps badly and refuses to eat. Diarrhea may occur.

High body temperature disrupts the course of internal biochemical reactions, negatively affects the functioning of the nervous and cardiovascular systems ^1.2 . In order to prevent the development of complications and adverse effects of hyperthermia, it is recommended to take antipyretic drugs that are graded by age and are available for adults and children separately ^1,3,5 . Do not give your child drugs intended for adults, even if the temperature of 39.3 ° C does not go astray. In this case, it is advisable to call an ambulance without taking rash independent actions.

What should I do if the temperature of 39.3 °C does not go away for a long time (2, 4 or more days)?
