How to Break a Fever

Fevers can be uncomfortable and even cause concern, but they’re often a sign that your body is fighting off an infection. In most cases, a fever will resolve on its own within a few days.

However, there are methods you can use to help break a fever and provide some relief.

Fever Symptoms

A fever is your body’s response to an infection or illness. Some common symptoms associated with a fever include:

Increased Temperature

When experiencing a fever, a hallmark sign is when your body’s temperature escalates beyond its typical range, which is from 97°F (36.1°C) to 99°F (37.2°C). 

A fever, generally defined as a body temperature reaching or exceeding 100.4°F (38°C), represents your body’s defensive response. This response aims to ward off infection by making the bodily environment less hospitable for the invading pathogens. 

The increase in body temperature during a fever supports your immune system to function more effectively while simultaneously hindering the growth and spread of infectious agents.


Chills are often experienced during a fever as your body tries to increase its temperature. You may shiver and feel cold even though your body temperature is rising.

Chills occur because your body is attempting to bridge the gap between its current temperature and the elevated set point.

Increased Sweating

Sweating is a common symptom of fever, and it often follows chills. It’s your body’s way of cooling down and regulating its temperature.

As your body temperature rises during a fever, it sweats to dissipate heat and help return your temperature to a more normal level.


Fever can lead to headaches because the body’s higher temperature can affect blood vessels and trigger the release of chemicals that cause pain and inflammation.

This results in the discomfort commonly associated with headaches during a fever.


Fever-induced fatigue occurs because your body is working hard to combat the infection.

The increased metabolic rate, along with other immune responses, can leave you feeling exhausted as your body redirects its energy to fight off the illness.

Body Discomfort

Fever often brings with it a general sense of discomfort. You may experience muscle aches, joint pain, and an overall feeling of being unwell.

This discomfort results from the body’s response to the infection, which can be distressing.


In some cases, fever can lead to confusion or altered mental status. Elevated body temperature can affect the brain’s functioning, causing confusion, delirium, or cognitive difficulties.

This is why confusion is considered a serious symptom of a high fever and may require medical attention.


In rare cases, especially in children, high fevers can trigger seizures, known as febrile seizures. The exact mechanism is not fully understood but is thought to be related to the rapid rise in body temperature.

Seizures during fever can be alarming and require immediate medical evaluation.

Skin Rashes

Fever can sometimes be accompanied by a rash, such as in cases of viral infections like measles or roseola.

The rash is typically a result of the body’s immune response and can be an additional symptom to help diagnose the underlying cause of the fever.

Lack of Energy

A fever can cause a significant decrease in energy levels because your body is diverting resources to fight the infection. This lack of energy makes you feel tired and weak, and it’s a natural response to conserve energy for the immune system’s efforts to combat the illness.

Causes of Fever

Fever can be triggered by a wide range of underlying factors, including viral and bacterial infections, inflammatory conditions, environmental factors, and even medications. Knowing the various causes of fever is crucial in determining effective management and treatment.


Fever is often a defense mechanism triggered by your body in response to infections. Common culprits include viral infections (such as the flu and COVID-19) and bacterial infections (like strep throat or urinary tract infections).

These pathogens stimulate your immune system, prompting the release of chemicals that raise your body temperature, creating an environment less hospitable for the infectious agents.

Disorders Related to the Immune System

Autoimmune disorders like lupus and certain types of vasculitis can trigger fever as part of the body’s immune response.

In these conditions, the immune system mistakenly targets the body’s own tissues, causing inflammation and fever as a result.


Fever can be a symptom of some cancers, particularly hematologic malignancies like leukemia and lymphoma.

It may be caused by the body’s response to the cancer cells or as a result of the cancer treatment, such as chemotherapy.

Hormone Level Changes

Your body’s temperature can fluctuate under hormonal influences. For example, for women undergoing their menstrual cycle, hormone levels vary significantly, potentially causing a mild increase in body temperature.

Additionally, major hormonal shifts, like during pregnancy or menopause, can result in temporary periods of increased body heat. It’s essential to understand that these hormonal changes can cause your body to mimic fever-like symptoms, even though you don’t have an actual fever.


Certain medications, including antibiotics, can lead to fever as a side effect. It’s essential to be aware of potential drug-induced fevers and consult with a healthcare professional if such symptoms arise. 

Adjusting medication or exploring alternative options may be considered to alleviate medication-related fevers.


Vaccines work by tricking your body into thinking it’s under attack, thereby stimulating the immune system. Fever is usually anticipated by the healthcare professional.

So, when you receive a vaccination, your body might react by raising its temperature to facilitate immune response and aid in developing immunity. This type of fever is generally temporary and harmless, signifying your body’s preparation to fight against the actual disease.

Trauma and Surgery

Fever can occur after surgeries or as a result of physical trauma.

This is often due to the body’s inflammatory response to tissue damage, infections that may occur post-surgery, or the introduction of foreign materials like implants or transplants. Prophylaxis medications are given in anticipation of the body’s response to surgical trauma.

Stress and Anxiety

High levels of stress and anxiety can occasionally lead to psychogenic fever, where your body temperature increases due to emotional or psychological factors.

While this type of fever is not caused by a physical illness, it’s a natural response to emotional stress.


Some individuals may experience a fever as a response to allergens, as seen in allergic reactions.

The body’s immune system releases chemicals in an attempt to combat the allergen, resulting in an increase in body temperature.

Environmental Factors

Environmental factors, such as exposure to extreme temperatures or inadequate ventilation, can contribute to fever. Ensuring a comfortable environment promotes recovery and aids in managing elevated body temperature effectively.

Remedies to Break a Fever

When a fever strikes, seeking effective remedies to break it and find relief becomes a top priority. Here are the different methods and strategies, both medical and home-based, to tackle fevers and alleviate their associated symptoms.

Drink More

Drink plenty of fluids, including water, clear liquids, and electrolyte-rich beverages, to stay well-hydrated.

Proper hydration is essential to avoid complications and support your body’s healing process.

Rest and Sleep

Your immune system functions best when you provide it with the rest it needs. Sleep provides an opportunity for your body to heal and recover, addressing underlying issues for your fever.

Make sure to stay at home and lie down whenever possible, as adequate sleep is crucial for your body’s recovery.

Cool Compress

Applying a cool compress to your forehead or the back of your neck can help bring down your body temperature when you’re running a fever.

The coolness of the compress absorbs the excess heat produced by your body, providing immediate relief from discomfort and gradually lowering your body temperature.

Lukewarm Baths

Lukewarm baths are a simple yet effective home remedy for fever management. When you have a fever, your body’s core temperature is elevated, and this can often lead to discomfort, sweating, and a general feeling of malaise.

Taking a lukewarm bath involves using water that is neither too hot nor too cold, typically around body temperature or slightly cooler.

Room Airflow

Good ventilation is vital when you’re dealing with a fever. Naturally, you would want to stay in a room that has proper air circulation.

When your room is well-ventilated, it enhances the evaporation of sweat from your skin. This process cools down your body, helping to reduce your high temperature and making you feel more comfortable.

Adjusting for Cooler Room Temperature

If you’re facing a fever, ensure your room’s temperature is adjusted to a cooler setting. Overly warm environments might make a fever worse by increasing your body temperature further.

On the other hand, a cooler room assists your body in releasing heat, breaking your fever more efficiently. However, remember to avoid low temperatures, as it may cause your body to shiver, leading to more heat generation.

Vitamin C-rich Foods

Incorporate foods rich in vitamin C into your diet, as they can help boost your immune system and reduce oxidative stress, potentially aiding in your recovery.

Remember, if your fever persists beyond a few days or is accompanied by severe symptoms, it’s crucial to seek guidance and consultation from a healthcare professional to ensure your well-being.

Over-the-Counter Medications

Over-the-counter (OTC) medications for fever, inflammation, and pain are effective in breaking a fever by targeting the body’s temperature regulation system.

They work by inhibiting the production of prostaglandins, which are chemicals in the body that elevate the temperature set point in the brain during a fever. 

By reducing the production of prostaglandins, these medications help the body return to its normal temperature, alleviating fever-related discomfort and promoting a quicker recovery.

When to Contact a Doctor

While fevers are typically your body’s natural response to infections, there are instances when they signal a more serious underlying issue. Here’s how you’ll know when to seek medical attention:

Extremely High Fever

An extremely high fever, typically above 103°F (39.4°C) in adults, can indicate a severe underlying condition. High temperatures can lead to cognitive issues and potentially dangerous complications.

It’s essential to seek medical attention when facing an extremely high fever to identify and address the cause promptly and provide effective fever reduction strategies.

Worrying Symptoms

When fever is accompanied by severe symptoms like difficulty breathing, chest pain, confusion, seizures, or persistent vomiting, it is a clear indication that medical attention is necessary.

These severe symptoms may be indicative of a serious condition that requires immediate evaluation and intervention to prevent further complications.

Long-Term Fever

A fever that lasts for more than a few days without showing signs of improvement should raise concerns. Prolonged fever can be a sign of a persistent infection, an inflammatory disorder, or an unresolved health issue.

If you experience recurrent fevers with no apparent cause, it could be a sign of an underlying health problem, chronic infection, or an autoimmune disorder.

Consulting a healthcare professional in such cases is crucial to determine the underlying cause and initiate appropriate treatment.

Existing Health Conditions

Individuals with underlying health conditions, such as diabetes, heart disease, or autoimmune disorders, are at higher risk when experiencing a fever.

The immune response can be compromised in these cases, and any fever should be promptly communicated to a healthcare provider to ensure that it is not a symptom of a worsening health issue.

Travel History

Fever accompanied by a recent history of travel to regions with endemic diseases is a significant red flag.

It may be a sign of travel-related illnesses, which can range from tropical diseases to food-borne infections.

When Things Do Not Work

When your fever worsens despite home care efforts or over-the-counter medications, it indicates that your condition is not improving as expected.

This could signal a worsening infection or a severe underlying issue.
