What are the common causes of high temperature. How can you recognize fever symptoms. When should you seek medical attention for a fever. What are the most effective treatments for high fever. How does the body regulate temperature during illness. What are the potential complications of untreated high fever. How can you prevent fever-related complications.

What Defines a Fever and How Does It Affect the Body?

A fever, also known as hyperthermia or pyrexia, is characterized by an elevated body temperature above the normal range. While individual baseline temperatures may vary, a reading of 100.4°F (38°C) or higher is generally considered a fever. This physiological response is typically triggered by the body’s immune system as it fights off infections or other health issues.

The hypothalamus, a region in the brain, acts as the body’s thermostat. During an infection or illness, it may reset the body’s temperature to a higher level. This elevation in temperature creates an environment less favorable for pathogens to thrive, thus aiding in the body’s defense mechanisms.

Common Symptoms Accompanying a Fever

• Chills or shivering
• Profuse sweating
• Headache
• General weakness
• Irritability
• Loss of appetite
• Dehydration

These symptoms often accompany a fever as the body works to combat the underlying cause. While uncomfortable, they are generally signs that your immune system is actively responding to a threat.

What Are the Primary Causes of High Body Temperature?

Fevers can be triggered by a wide range of factors, with infections being the most common culprit. Understanding these causes can help in determining the appropriate course of action and treatment.

Infectious Causes of Fever

• Viral infections (e.g., common cold, influenza, COVID-19)
• Bacterial infections (e.g., strep throat, urinary tract infections)
• Parasitic infections (e.g., malaria)
• Fungal infections

Non-Infectious Causes of Fever

• Autoimmune disorders (e.g., lupus, rheumatoid arthritis)
• Certain medications
• Vaccines and immunizations
• Heat exhaustion or heat stroke
• Hormonal imbalances (e.g., hyperthyroidism)
• Some cancers
• Blood clots

In rare cases, a fever may be classified as a “fever of unknown origin” when the cause remains elusive despite thorough medical investigation. These cases often require more extensive diagnostic procedures to identify the underlying issue.

When Should You Seek Medical Attention for a Fever?

While most fevers are not dangerous in themselves, certain circumstances warrant immediate medical attention. Understanding these situations can help you make informed decisions about when to consult a healthcare professional.

Fever in Adults

For adults, medical attention is recommended if:

• The temperature reaches 103°F (39.4°C) or higher
• The fever persists for more than three days
• The fever is accompanied by severe headache, stiff neck, or confusion
• There are signs of dehydration, such as decreased urine output
• You have a known weakened immune system
• You’ve recently traveled to an area with endemic infectious diseases

Fever in Children

For children, the guidelines are more stringent:

• For infants under 3 months: Any rectal temperature of 100.4°F (38°C) or higher requires immediate medical attention
• For children 3-6 months: A rectal temperature above 102°F (38.9°C) or any fever with irritability or lethargy
• For children 6-24 months: A fever above 102°F (38.9°C) lasting more than a day, especially if accompanied by other symptoms like cough or diarrhea
• For children over 2 years: A fever accompanied by a rash, persistent symptoms, or signs of dehydration

It’s crucial to remember that in children, the height of the fever doesn’t necessarily correlate with the severity of the illness. The child’s behavior and other symptoms are often more indicative of the need for medical attention.

How Is a Fever Diagnosed and What Tests Might Be Performed?

Diagnosing the underlying cause of a fever often involves a comprehensive approach. While measuring body temperature is straightforward, identifying the root cause can be more complex.

Initial Assessment

The diagnostic process typically begins with:

• A thorough medical history, including recent travel, medications, and potential exposure to infections
• A physical examination to check for signs of infection or other health issues
• Accurate temperature measurement using an appropriate thermometer

Additional Diagnostic Tests

Depending on the initial findings, your healthcare provider may recommend:

• Blood tests to check for infection markers, autoimmune indicators, or other abnormalities
• Urine tests to rule out urinary tract infections
• Chest X-rays if a respiratory infection is suspected
• Cultures of blood, urine, or other bodily fluids to identify specific pathogens
• Imaging studies such as CT scans or MRIs if structural issues are suspected

In cases of persistent fever without an apparent cause, more specialized tests may be necessary to diagnose conditions such as autoimmune disorders or occult infections.

What Are the Most Effective Treatments for Fever?

The treatment of fever often focuses on managing symptoms and addressing the underlying cause. The approach can vary depending on the severity of the fever and its origin.

Over-the-Counter Medications

Common treatments include:

• Acetaminophen (Tylenol): Effective for reducing fever and alleviating discomfort
• Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen: Help reduce fever and relieve pain

It’s important to note that aspirin should be avoided in children and teenagers due to its association with Reye’s syndrome, a rare but serious condition.

Supportive Care

In addition to medication, supportive measures can help manage fever:

• Staying hydrated by drinking plenty of clear fluids
• Resting to allow the body to focus on fighting the infection
• Using lightweight clothing and bedding to prevent overheating
• Taking lukewarm baths to help lower body temperature comfortably

Treating the Underlying Cause

For fevers caused by specific conditions:

• Antibiotics may be prescribed for bacterial infections
• Antiviral medications might be used for certain viral infections
• Anti-inflammatory drugs may be recommended for autoimmune conditions

It’s crucial to follow your healthcare provider’s advice and complete any prescribed course of medication, even if symptoms improve before completion.

How Can You Prevent Fever-Related Complications?

While fevers are often beneficial in fighting infections, prolonged or extremely high fevers can lead to complications. Taking proactive steps can help prevent these issues and promote a faster recovery.

Preventing Dehydration

Dehydration is a common complication of fever. To prevent it:

• Drink plenty of fluids, including water, clear broths, and electrolyte solutions
• Monitor urine output and color – dark urine may indicate dehydration
• Offer frequent small sips of fluid to children who may not feel like drinking

Monitoring Temperature

Regularly checking body temperature can help you:

• Track the progression of the fever
• Determine the effectiveness of fever-reducing medications
• Identify when medical attention may be necessary

Recognizing Warning Signs

Be alert for signs that may indicate a worsening condition:

• Persistent high fever not responding to treatment
• Severe headache or confusion
• Difficulty breathing
• Persistent vomiting or diarrhea
• Seizures or loss of consciousness

If any of these symptoms occur, seek immediate medical attention.

What Role Does the Immune System Play in Fever?

The immune system is intricately involved in the fever response, using elevated body temperature as a tool to combat pathogens and restore health.

Fever as a Defense Mechanism

When the immune system detects an invading pathogen, it triggers a series of responses:

• Release of pyrogens, substances that cause fever
• Activation of white blood cells to fight infection
• Increased production of antibodies

The elevated temperature creates an environment less favorable for many pathogens to thrive, while simultaneously enhancing immune system function.

Cytokines and Fever

Cytokines, small proteins crucial for cell signaling, play a significant role in fever:

• They act as messengers between immune cells
• Some cytokines, like interleukin-1 and tumor necrosis factor-alpha, are potent inducers of fever
• They help coordinate the body’s overall immune response

Understanding this intricate relationship between the immune system and fever helps explain why fever is often a positive sign of the body actively fighting an infection.

How Do Different Age Groups Experience and Handle Fever?

The impact and management of fever can vary significantly across different age groups, from infants to the elderly. Understanding these differences is crucial for appropriate care and knowing when to seek medical attention.

Infants and Young Children

Fever in young children requires special attention:

• Infants under 3 months with any fever should receive immediate medical care
• Young children may experience febrile seizures, which are generally harmless but can be frightening
• Children’s temperatures can rise quickly, necessitating close monitoring

Adults

For adults, fever management typically involves:

• Over-the-counter fever reducers when necessary
• Monitoring for signs of more serious underlying conditions
• Maintaining hydration and rest

Elderly Individuals

Older adults may experience fever differently:

• They may not develop high fevers even with serious infections
• Cognitive changes or confusion may be the first sign of illness
• Underlying health conditions can complicate fever management

Recognizing these age-related differences can help in providing appropriate care and knowing when professional medical advice is necessary.

What Are the Latest Advancements in Fever Research and Treatment?

The field of fever research continues to evolve, with new insights and treatments emerging regularly. These advancements are shaping our understanding of fever and improving patient care.

Targeted Fever Management

Recent research has led to more nuanced approaches to fever treatment:

• Recognition that not all fevers require treatment, as they can be beneficial in fighting infections
• Development of more precise guidelines for when to intervene with fever-reducing medications
• Exploration of the role of fever in specific conditions, such as sepsis or neurological injuries

Novel Therapeutic Approaches

Emerging treatments and technologies include:

• Development of new antipyretic drugs with fewer side effects
• Investigation of immunomodulatory therapies that work in conjunction with the body’s fever response
• Advancements in cooling technologies for managing dangerously high fevers

Improved Diagnostic Tools

Innovations in diagnostics are enhancing our ability to identify fever causes:

• More sensitive and specific biomarkers for differentiating between viral and bacterial infections
• Advanced imaging techniques for detecting occult sources of fever
• Rapid point-of-care testing for common infectious agents

These advancements promise to improve the accuracy of diagnoses and the effectiveness of treatments, ultimately leading to better outcomes for patients experiencing fever.

High Temperature Causes and Treatments

A fever is a body temperature that’s higher than is considered normal. It’s also called a high temperature, hyperthermia, or pyrexia, and it’s usually a sign that your body is working to keep you healthy from an infection. Normal body temperatures are different for everyone, but they lie within the range of 97 to 99. A temperature of 100.4 or higher is considered a fever.

A part of your brain called the hypothalamus controls your body temperature. In response to an infection, illness, or some other cause, the hypothalamus may reset the body to a higher temperature. So when a fever comes on, it’s a sign that something is going on in your body.

Fevers themselves generally aren’t dangerous, but you should check in with your doctor if:

• An adult’s temperature is 103 or higher
• A very young infant (under 3 months) has a rectal temperature 100. 4 or higher (call your doctor or go to an emergency room immediately)
• A 3-6-month-old has a higher than normal rectal temperature and is also irritable or sleepy (call your doctor right away)
• A 3-6-month-old has a 102 or higher rectal temperature
• A 6-24-month-old has a fever higher than 102 for more than a day or with other symptoms such as a cough or diarrhea
• A child older than 2 has a fever that comes with rash, real discomfort, irritability, listlessness, headache, stiff neck, or repeated diarrhea or vomiting
• An infant or child has a seizure
• Any temperature over 104 in a child, which could cause a seizure
• Any fever that starts after someone has been in hot temperatures, which could be a sign of heat stroke
• The fever doesn’t go down after taking over-the-counter medications such as ibuprofen in the appropriate doses
• You’ve been in contact with someone who has COVID-19

Fevers are signs of some sort of illness or infection. When you have, you may also notice these symptoms:

• Chills or shivering
• Sweating
• Headache
• Feeling weak
• Being irritable
• Losing your appetite
• Being dehydrated

A fever can be a sign of several health conditions, which may or may not need medical treatment.

The most common causes of fever are infections such as colds and stomach bugs (gastroenteritis). Other causes include:

• Infections of the ear, lung, skin, throat, bladder, or kidney
• Heat exhaustion
• COVID-19
• Sunburn
• Conditions that cause inflammation, such as rheumatoid arthritis
• Side effects of medications
• Vaccines and immunizations
• Blood clots
• Autoimmune conditions such as lupus and inflammatory bowel disease (IBS)
• Cancer
• Hormone disorders such as hyperthyroidism
• Illegal drugs such as amphetamines and cocaine
• Teething in babies can cause a mild, low-grade fever (not over 101 degrees)

Although a fever is easy to measure with a thermometer, finding its cause can be hard. Besides a physical exam, your doctor will ask about symptoms and conditions, medications, and if you’ve recently traveled to areas with infections or have other infection risks. A malaria infection, for example, may cause a fever that typically comes back. Some areas of the U.S. are hot spots for infections such as Lyme disease and Rocky Mountain spotted fever.

Your doctor may ask if you have been around someone with COVID-19 or have any other symptoms of COVID-19.

Sometimes, you may have a “fever of unknown origin.” In such cases, the cause could be an unusual or not obvious condition such as a chronic infection, a connective tissue disorder, cancer, or another problem.

Fever is usually associated with physical discomfort, and most people feel better when a fever is treated. But depending on your age, physical condition, and the underlying cause of your fever, you may or may not require medical treatment for the fever alone. Many experts believe that fever is a natural bodily defense against infection. There are also many non-infectious causes of fever.

Treatments vary depending on the cause of the fever. For example, antibiotics would be used for a bacterial infection such as strep throat.

The most common treatments for fever include over-the-counter drugs such as acetaminophen and nonsteroidal anti-inflammatory drugs such as ibuprofen and naproxen. Children and teens should not take aspirin because it’s linked to a condition called Reye’s syndrome.

Stay comfortable by: 

• Drinking a lot of clear liquids such as water, broth, and juices or a rehydration drink.
• Taking a lukewarm bath.
• Resting.
• Keeping yourself cool with lightweight clothing and bed coverings.

what to do, what temperature is considered high and why it is dangerous, causes and symptoms

Fever, fever – this is what we call an increase in body temperature. This is the most important defense mechanism of the human body and one of the main symptoms of infection. Most often, we encounter a fever with colds and flu. High temperatures cause some discomfort, but it helps to cope with the disease faster. We will tell you why adults have a fever, when it is necessary to bring down the temperature, and in what cases it is not worth it.

Why the temperature rises

¹

Body temperature can rise for various reasons: due to overheating, inflammation, hormonal imbalance. The processes of heat transfer in the human body are regulated by a small part of the brain – the hypothalamus. The temperature rises with any physical or chemical impact on it.

An increase in body temperature associated mainly with infections is called a fever. It develops when biologically active substances, cytokines, act on the hypothalamus. The immune system releases them into the blood in response to the inflammatory process. The production of cytokines is also enhanced by the waste products of microbes.

Fever is one of the main symptoms of an acute respiratory viral infection (ARVI). But it is also a protective reaction of the body, aimed at fighting the virus. When the temperature rises, the immune system synthesizes more leukocytes, which destroy or inactivate pathogenic microbes, and interferons, natural antiviral substances.

What temperature is considered high

^2.3

A temperature above 37˚C measured in the armpit is considered elevated. When measuring temperature in the oral cavity, a temperature of more than 37.2˚C is considered elevated, and in the rectum – more than 37.8˚C.

Types of fever:

● Subfebrile – 37.5–38˚C. Accompanies a chronic or easily flowing acute infection.

● Febrile – 38-39˚C. A frequent companion of most acute inflammatory processes – infectious and non-infectious.

● Pyretic (high) – 39-41˚C. This is one of the signs of a moderate flu. High fever is accompanied by symptoms that worsen well-being.

● Hyperpyretic (critically high) – more than 41˚C. It occurs in a severe form of influenza, causes life-threatening disorders of body functions.

What symptoms accompany fever

^{4, 5}

Subfebrile temperature is accompanied by weakness, feeling of weakness, headache, drowsiness, chills. At a temperature of 38˚C, the skin becomes hot, the cheeks turn red, the patient feels intense heat, dry mouth. Lips dry out and crack. With pyretic fever, nausea and vomiting may join. Hyperpyretic temperature is often accompanied by a disorder of consciousness, delirium.

Fever increases blood pressure and heart rate. An increase in temperature by one degree increases the pulse by 10-15 beats per minute.

What diseases occur with fever

⁶

The most common cause of fever in adults is acute respiratory viral infections (ARVI):

● Coronavirus, rhinovirus infection. This is SARS, affecting mainly the mucous membranes of the nasal cavity and pharynx. Symptoms: runny nose, redness and sore throat, sneezing, coughing. The temperature is subfebrile (37–38˚С) or febrile (38–39C).

● Influenza. Influenza viruses can immediately affect the lower respiratory tract and cause a deep chest cough. Infection is most often accompanied by severe intoxication, which is manifested by headache, aching throughout the body, and severe weakness. The temperature can reach pyretic (39-41˚C) and hyperpyretic (over 41˚C).

● Respiratory syncytial virus infection. It often affects the trachea and bronchi, in a quarter of the patients it leads to pneumonia. Symptoms are similar to the flu, with the difference that intoxication is less pronounced, signs of inflammation of the lower respiratory tract come to the fore – a deep cough with pain behind the sternum.

● Parainfluenza. The virus infects the nasal cavity, pharynx, larynx. The infection is accompanied by a runny nose, bouts of painful coughing, hoarseness, and sometimes a short-term loss of voice.

● Adenovirus infection. Runs with severe runny nose, sneezing, conjunctivitis. The eyes turn red, watery, there is pain and burning in the area of ​​​​the eyeballs and eyelids. Unlike other acute respiratory viral infections, adenovirus infection is often infected in spring and summer.

Other causes of fever:

● any infectious disease of a viral, bacterial, parasitic nature;

● non-infectious inflammations: acute pancreatitis, aspiration pneumonitis;

● allergic and autoimmune diseases: reaction to vaccination, rheumatoid arthritis, systemic lupus erythematosus;

● diseases of the thyroid gland, adrenal glands;

● oncological diseases: malignant tumors of internal organs, leukemia, lymphogranulomatosis;

● neurological pathologies: traumatic brain injury, cerebral hemorrhage;

● thermal (solar) stroke;

● psychogenic: prolonged emotional stress, neuroses, hysteria.

When temperature rise is dangerous

Fever poses a threat to health with a strong rise in temperature, when the thermometer shows 40˚C or more. This condition leads to dehydration, disruption of vital organs, and significantly increases the risk of thrombosis.

For healthy adults, an increase in temperature during SARS by 3˚C from the norm (36.6˚C) is not dangerous. However, for some people, even a febrile temperature can be harmful. At risk:

● Elderly people. After 65 years, it is more difficult for the body to adapt to an increase in temperature due to the age-related decrease in the ability to thermoregulate, the acquisition of chronic diseases.

● People with chronic diseases of internal organs: kidneys, cardiovascular, nervous system. Fever increases the load on these organs and can lead to an exacerbation of the disease.

What to do when the temperature is high

⁷

Fever helps to defeat the infection faster. With ARVI without fever, the infection takes longer, is accompanied by a pronounced deterioration in well-being, and is more often complicated. Therefore, it is worth suffering malaise for 2-3 days and not bringing down the temperature, provided that the body temperature does not exceed 38.5˚C. To make it easier to transfer the condition, avoid any physical activity, drink plenty of fluids, do not wrap yourself in blankets and excessively warm clothes that impair heat transfer.

But there are times when it is better to bring down the temperature:

● The thermometer reads over 39˚C.

● The rise in temperature is accompanied by a strong deterioration in the condition: loss of strength, poor sleep, nausea, vomiting.

● The patient is at risk.

Fever above 40˚C in adults requires emergency medical attention.

Non-drug methods. Wiping with a damp cloth or a weak vinegar solution will help to reduce the temperature. It is recommended to drink more warm drinks, such as tea with raspberry jam. Raspberries contain natural salicylates – substances that reduce fever. Drink should be moderately warm. Excessively hot or cold drinks and foods should be avoided.

Antipyretics. If non-drug treatments do not help, take an antipyretic medication. The safest drugs are paracetamol-based, which can be taken even by small children and pregnant women. Paracetamol is included in most combined anti-cold complexes, which additionally relieve nasal congestion and symptoms of intoxication in acute respiratory viral infections.

Antivirals. Lowering the temperature is not an end in itself in the treatment of SARS. Antiviral therapy should fight the causative agent of the infection. To do this, develop specific antiviral drugs that prevent the reproduction of the virus and infection of healthy cells. In the treatment of colds and flu, enisamium iodide has proven itself well. Its use reduces the acute clinical manifestations of viral intoxication. ⁸

Enisamia iodide at a dosage of 500 mg is part of the drug Nobasit ^® Forte ⁸ . Nobasit ^® Forte begins to act within 2 hours after taking the tablet ^8. In addition to the direct antiviral effect, enisamia iodide has a pronounced anti-inflammatory activity ^{9, 10} . The combined action leads to a 3-fold decrease in the severity of fever and other symptoms of intoxication (headache and muscle pain), starting from the second day of treatment ¹¹ . Also Nobasit ^® Forte helps to reduce the duration of the disease. ⁸

Briefly about the main

● Elevated is defined as a temperature above 37˚C measured in the armpit. If it is caused by an infection, this temperature is called a fever.

● The most common cause of fever in adults is SARS. Other causes – infections, non-infectious inflammation, heat stroke, stress, malignant tumors – are much less common.

● Fever brings recovery closer, but often it greatly affects well-being: it is accompanied by weakness, headache, body aches. In the elderly and people with common chronic diseases, fever often causes dangerous complications.

● Cool down in healthy adults should be above 38.5˚C and in at-risk people above 38˚C. If the temperature rises above 40˚C, it is worth calling an ambulance.

● First, try to bring down the temperature with home remedies – cool body wraps, tea with raspberry jam. If that doesn’t help, take an antipyretic medicine.

● Antipyretics will ease the fever but will not speed up recovery. To defeat the infection as soon as possible, take antiviral drugs, for example, Nobasit ^®
Forte.

High temperature

High temperature (fever, hyperthermia) is a normal and healthy reaction of the body to an infection – bacterial or viral. Actually, fever is a symptom of a disease, not a disease. An increase in body temperature helps kill the virus or bacteria causing the infection.

High body temperature is considered if it is 38°C or higher. An area of ​​the brain called the hypothalamus regulates body temperature. If body temperature rises above or falls below 37°C, the hypothalamus begins to regulate temperature.

The degree of fever may not indicate how serious the condition is. With a minor illness, such as a cold, a fever may rise, and with a very serious infection, there may be little or no temperature at all. Along with fever, other symptoms are also important.

High temperature symptoms

Light (subfebrile) temperature 37.1-37.9

At a light temperature, a blush appears, fatigue is felt, the body is warm to the touch. There may be a headache. Typically, a person with a mild fever can perform normal daily activities.

Moderate (febrile) temperature (38° to 38.9°C)

High (pyretic) temperature (39° to 41°C)

At moderate and high temperatures, the heat of the skin is felt to the touch, chills or trembling appear. Because of the feeling of weakness, I want to lie down.

Excessive (hyperpyretic) temperature (41°C or higher)

With excessive temperature, severe weakness is felt, it is difficult for a person to move, appetite disappears. Quite quickly, especially in children, dangerous signs of dehydration appear: rare urge to urinate, pale skin, dry lips, etc.

Causes

Common conditions that can cause a high body temperature include:

• acute respiratory infections,
• influenza and influenza-like conditions,
• gastroenteritis,
• ENT infections (sinusitis, tonsillitis, otitis, etc.),
• kidney or urinary tract infections,
• infectious childhood diseases such as chicken pox, scarlet fever, rubella (rubella), whooping cough and rheumatic fever,
• heatstroke,
• Teething in infants can cause mild low-grade fever, etc.

After vaccination, the temperature may also rise slightly – this is considered a variant of the norm.

Fever diagnostics

Despite the fact that the temperature is easy to measure with a thermometer, the cause of its rise can only be determined after clarifying all the symptoms and previous conditions.

Treatment of fever

Elevated body temperature is part of the immune system’s response to bacteria, viruses, and other pathogens. Helps the body fight infection. However, very high temperatures can sometimes lead to complications.

The most common treatments for fever include over-the-counter over-the-counter medications. Children and teenagers should not take aspirin because it has been linked to a condition called Reye’s syndrome.

To reduce elevated body temperature at home contribute to:

• drink plenty of water (water, compotes, juices, rehydrating drinks, etc.),
• bed rest,
• keeping the room cool,

Treatment of fever in a child

Usually, parents care for their child at home, and pediatricians recommend starting measures to lower the temperature if it has risen to 38. 5 ° C. It is safe to alternate between ibuprofen and paracetamol at the age-appropriate dose. In addition to taking children’s pharmaceutical antipyretics in a dosage appropriate for the age and weight of the child, you should:

• undress the child to the linen,
• do not wrap, do not cover with a warm blanket;
• give the child plenty of fluids;
• regularly check the child’s condition at night;
• offer the child light food.

Do not wipe or splash the child with cold water.

Call your pediatrician immediately if your child:

• is less than 3 months old and has a temperature of 38°C,
• age 3 to 6 months and temperature 39°C or more,
• if, in addition to high fever, there are other signs of illness, such as rash, etc.,
• high fever persists for more than 5 days,
• high temperature in a child is not reduced by paracetamol or ibuprofen,
• showed signs of dehydration – infrequent urination, sunken eyes and no tears if the child cries.
