Can You Sweat Out A Fever?

Updated: Mar 27

Can You Sweat Out A Fever?

Fever, something many people experience, often makes us wonder how to feel better. One question that's been around for a long time is, "Can you sweat out a fever?" In this detailed guide, we'll look into how sweating relates to fever and whether it really helps lower body temperature.

What is a Fever?

A fever is when your body temperature goes above the normal range of 98.6°F (37°C). It's your body's way of fighting infections or other health problems. Knowing more about fever helps us understand how our bodies react when we're sick.

Understanding Fever

The body works hard to control its temperature, and fever is part of that process. When your immune system detects germs, it releases chemicals that raise your body temperature. This helps make it harder for the germs to survive and spread.

Causes of a Fever

Fever happens for many reasons, from simple infections to more serious health issues. Knowing what causes it helps doctors treat it right. Some common causes of fever include:


Infections like viruses, bacteria, fungi, and parasites are common reasons for fever. When the body fights off invaders like the flu, colds, pneumonia, or urinary tract infections (UTIs), it can cause a fever.

Inflammatory Conditions

When the body reacts to injury or sickness, it can cause inflammation, which sometimes leads to a fever. Conditions like rheumatoid arthritis, lupus, and inflammatory bowel diseases (like Crohn's disease and ulcerative colitis) can bring on a fever as the body's immune system reacts. These illnesses prompt the release of chemicals that can make the body temperature rise.

Autoimmune Disorders

Autoimmune disorders happen when your immune system messes up and attacks your body's own tissues. Conditions like autoimmune hepatitis, lupus, and rheumatoid arthritis can make you get fevers often because your immune system thinks your body is under attack.


Some medicines, especially those that boost the immune system or cause allergies, can give you a fever as a side effect. Antibiotics, anticonvulsants, and some painkillers are examples of drugs that might sometimes cause a fever. If you get a fever after starting a new medicine, it's best to talk to a doctor.


Some vaccines, like the flu shot or the pneumococcal vaccine, might give you a slight fever. It's just your body's way of reacting to the vaccine and building protection.

Heat-Related Illnesses

Being out in hot weather or doing a lot of activity in the heat can make you feel sick. You might get dehydrated, have a high body temperature, and sweat a lot. If it gets really bad, you could have heatstroke, which needs urgent medical help.


Certain kinds of cancer, such as leukemia and lymphoma, can make you have a fever because your body reacts to the cancer cells growing or the substances they release. This fever might show there's an infection or swelling because of the cancer.

Endocrine Disorders

Problems with the endocrine system, like having too much thyroid hormone or not enough adrenal hormones, can mess up how your body controls temperature and cause a fever.

Neurological Disorders

Some brain problems like meningitis and encephalitis can bring on a fever because they make the brain or its nearby parts swell up. These problems are serious and need quick medical help.

Tissue Injury or Surgery

When you get hurt or have surgery, your body reacts by causing inflammation in the injured area to heal it. Sometimes, this can lead to a fever as part of the healing process.

Other Causes

Fever can happen because of other things too, like blood clots, thyroid problems, or reactions to drugs. Babies might get a bit warmer when they're teething, but it's not usually a real fever.

Symptoms of a Fever

A fever shows up with different symptoms that can be mild or strong and last for different amounts of time. Some common signs of a fever include:

  • Elevated Body Temperature: The main sign of a fever is when your body temperature goes up from the normal range of 98.6°F (37°C). Fever temperatures usually go from 100.4°F (38°C) to 104°F (40°C) or even higher, depending on why you have it. You can check if you have a fever by using a thermometer to measure your body temperature.

  • Chills and Shivering: When your body temperature goes up, you might start shaking and feel cold. This is because your brain wants to warm you up, so it makes you shiver to create heat.

  • Sweating: When you have a fever, you might sweat a lot. It's your body's way of cooling down. But sweating too much can make you lose water and important minerals from your body.

  • Headache: When you have a fever, it's common to get a headache or feel discomfort in your head. This might happen because your blood flow changes, or you're not drinking enough water, or your body is fighting off an infection or inflammation.

  • Muscle Aches: When you have a fever, your muscles might ache or feel sore. It can happen in different parts of your body. Dehydration or infections can make these muscle aches worse.

  • Fatigue and Weakness: When you have a fever, you might feel really tired, weak, and like you have no energy. Your body works hard to fight off the infection or inflammation, which can make you feel exhausted and not very active.

  • Loss of Appetite: Not feeling hungry is common when you're sick. It can lead to dehydration if you don't drink enough fluids. Eating less can make you feel even more tired and weak. It's crucial to drink plenty of fluids and eat nutritious foods to help you feel better.

  • Irritability and Restlessness: When you have a fever, you might feel uncomfortable and have trouble sleeping like usual, which can make you feel restless or easily annoyed. Kids, especially, might get more grumpy or fussy when they have a fever.

  • Cough and Respiratory Symptoms: If you have a fever, you might also have a cough or trouble breathing. These extra symptoms help figure out why you have a fever.

  • Nausea and Vomiting: Fever might make you feel sick to your stomach and throw up. This can make you lose fluids, so it's important to drink enough water when you have a fever.

Why Does Your Body Sweat When You Have a Fever?

When your body gets hotter than usual during a fever, it starts to sweat. Sweating helps your body cool down. Your sweat glands start working, releasing wetness onto your skin. When the sweat dries up, it cools you down, bringing your body temperature back to normal.

Can You Sweat Out a Fever?

Many people think sweating can help when you have a fever, but let's clear things up. While sweating is your body's way of cooling down, it doesn't fix the real issue causing the fever. When your body gets hot because of a fever, your sweat glands start working to cool you down. Sweating helps to lower your body temperature temporarily. But it doesn't deal with what's making you sick.

Fever usually happens because of an infection or illness. Just sweating it out won't get rid of the problem. But sweating can make you feel better when you have a fever. It might help with things like feeling cold, achy muscles, and headaches. Sweating also helps get rid of some toxins through your skin.

To sweat when you have a fever, you can try things that make you warm, like taking a warm bath, using blankets, or doing light exercises. But always make sure to drink plenty of water to stay hydrated. Dehydration can make a fever worse and isn't good for your health.

Does Sweating Mean the Fever is Breaking?

Thinking that sweating means your fever is going away isn't entirely accurate. Sweating is just your body trying to find its balance again. Even if you sweat a lot, the fever might not go away right after. It's important to have a good plan to deal with the fever, not just rely on sweating.

Is it Healthy to Sweat Out a Fever?

While sweating is a natural response, going all-in on sweating to beat a fever isn't the smartest move. Too much sweating without enough hydration can lead to dehydration. Dehydration is like adding fuel to the fire—it brings a whole new set of problems. So, it's not just about sweating; it's about finding the right balance and keeping yourself well-hydrated.

Benefits of Sweating Out A Fever

Sweating out a fever has benefits for your body's healing and overall health during sickness:

1. Regulation of Body Temperature

Sweating is important for controlling body temperature when you have a fever. When your body gets hotter because of an infection or swelling, sweating helps to cool it down. This natural cooling helps to make you feel more comfortable when you're feverish.

2. Detoxification

Some people think that sweating when you have a fever helps your body get rid of toxins through your skin. Although experts aren't sure how much sweating helps with detoxification, sweating might help remove some waste from your body.

3. Enhanced Immune Response

Studies show that a bit of heat stress, like sweating when you're feverish, might perk up your immune system. When your body temperature goes up, it can kick-start some immune cells, helping your body spot and fight germs better. So, sweating during a fever could help your immune system step up its game.

4. Promotion of Circulation

Sweating when you have a fever can help blood move around your body more efficiently. This means more oxygen and nutrients get to your cells, while waste gets taken away faster. It's like a natural boost for your immune system.

5. Alleviation of Discomfort

When you sweat out a fever, it can make you feel more comfortable. It can ease symptoms like shivering, sore muscles, headaches, and just feeling unwell. Plus, sweating can release endorphins, which are natural feel-good chemicals in your body, making you feel more relaxed and happier.

6. Promotion of Relaxation

When you sweat during a fever, it helps you relax and feel less stressed. Your body releases tension, making you feel more balanced. This relaxation helps you feel better and supports your body's recovery.

7. Facilitation of Restful Sleep

Sweating during a fever can help you sleep better. It helps control your body temperature and reduces discomfort from the fever. Getting good sleep is important for your immune system and helps you recover from being sick.

8. Natural Symptom Relief

Sweating is a natural way to ease symptoms during a fever. It uses your body's own healing power without needing medicines or treatments from outside.

9. Support for Holistic Healing

Embracing fever and sweating it out fits with the idea of holistic healing. It respects how our bodies work naturally and helps us heal on our own. It's about supporting our body's built-in ability to heal itself, which can make us stronger and healthier in the long run.

Potential Side Effects of Sweating Out a Fever

Sweating out a fever can help ease symptoms and aid the healing process, but it's essential to watch out for potential drawbacks:

  • Dehydration: Too much sweating when you have a fever can make you lose too much water and minerals from your body, causing dehydration. Dehydration can make you feel more tired, dizzy, and weak. It's important to drink plenty of water or sports drinks to stay hydrated.

  • Electrolyte Imbalances: Sweating too much during a fever can make you lose important minerals like sodium, potassium, and chloride, which your body needs to work properly. This can cause problems like muscle cramps, weakness, and feeling dizzy. Drinking water or sports drinks can help replace these lost minerals and keep you hydrated.

  • Fatigue and Weakness: When you have a fever for a long time and sweat a lot, it can make you feel tired, weak, and lazy. Your body might not have enough energy and nutrients to fight off the illness and get better.

  • Heat Exhaustion: Being in hot weather for a long time and sweating too much can make you get heat exhaustion. It makes you sweat a lot, feel weak, sick to your stomach, get headaches, and even pass out. If you don't take care of it, it can turn into heatstroke, which is really serious and needs a doctor right away.

  • Heatstroke: Heatstroke is when your body gets too hot and can't cool down properly. You might have a really high body temperature, feel confused, have a fast heartbeat, and your skin could feel hot and dry. It's a serious emergency and needs medical help right away to avoid big problems.

  • Exacerbation of Symptoms: Sweating out a fever might make symptoms worse or make the illness last longer. Too much sweating can cause discomfort, skin problems, and make existing health issues worse, especially for people with weaker immune systems or other health problems.

  • Compromised Immune Function: Too much sweating during a fever can weaken the immune system and make it harder for the body to fight off germs. This might make it easier to get other infections and take longer to get better.

  • Skin Irritation and Rashes: Too much sweating during a fever can cause skin irritation and rashes. This might happen in areas where there's a lot of rubbing or moisture. Keeping the skin clean and dry can help prevent these problems.

  • Temperature Fluctuations: Sweating during a fever helps lower body temperature. But the body's way of controlling temperature might act strangely. Quick cooling from sweating and then a sudden return to normal temperatures might confuse the body. This could cause temperature ups and downs that aren't good for health.

When to See a Doctor

Knowing when to see a doctor for a fever depends on factors like how long it lasts, how bad the symptoms are, and your general health.

  • Prolonged or High Fever: If your fever lasts a long time or gets very high, it's important to see a doctor right away. They can figure out what's causing it and give you the right treatment.

  • Severe Symptoms as Red Flags: If you have serious symptoms like trouble breathing, chest pain, or confusion, see a doctor right away. They can help you get the care you need quickly to prevent any complications.

  • Vulnerable Populations: Babies, old people, or those with health problems may need to see a doctor sooner if they have a fever. It's important to understand their special needs to keep them safe and healthy.

3. What are some natural ways to induce sweating?

  • Moving around, sitting in a steamy sauna or steam room, and eating spicy foods are usual ways to get sweating going.

4. When should I seek medical attention for a fever?

  • If you have a high fever and severe symptoms like headache, confusion, trouble breathing, chest pain, or constant vomiting, it's time to seek medical help.

5. How can I manage a fever at home?
