THE FLU: Could Sauna Help or Be Good For It?

The flu, also known as influenza, is a common viral infection that can have potentially serious consequences. It's more than just a runny nose and a sore throat. The flu can knock you off your feet, with symptoms such as fever, cough, and body aches. But could something as simple as a sauna session help combat this illness? Let's delve into the scientific evidence and explore the potential benefits and drawbacks of using a sauna when you have the flu.

Understanding the Flu

Before we dive into the potential benefits of a sauna for the flu, it's important to understand what the flu is and how it affects your body. Influenza is a highly contagious viral infection that primarily affects the respiratory system. It's not the same as the common cold, which is less severe.

Flu symptoms can range from mild to severe and can even lead to hospitalization or death in extreme cases. Most people who get the flu will recover in a few days to less than two weeks, but some people may develop complications, such as pneumonia, which can be life-threatening.

The Flu Virus and Your Immune System

When the flu virus enters your body, it triggers an immune response. Your body's immune cells attack the virus, causing inflammation and flu symptoms. The fever that often accompanies the flu is actually a sign that your body is fighting off the infection.

However, the immune response to the flu virus can sometimes be too strong, leading to excessive inflammation and damage to healthy tissues. This is why it's important to support your immune system and help it respond appropriately to the flu virus.

What is a Sauna?

A sauna is a small room or building designed to induce sweating and increase body temperature. The heat in a sauna can be generated by wood, electricity, or infrared light. Saunas have been used for centuries in various cultures, primarily for relaxation and health benefits.

The heat from a sauna can make you sweat profusely, and this sweating is thought to have various health benefits. But can these benefits extend to fighting off the flu? Let's explore the science behind this.

How Could a Sauna Help the Flu?

There are several ways in which a sauna could potentially help with the flu. These include boosting your immune system, relieving symptoms, and helping your body detoxify.

Boosting Your Immune System

Research has shown that heat exposure from a sauna can stimulate the immune system. A study published in the Journal of Human Kinetics found that sauna use can increase the number of white blood cells, lymphocyte, neutrophil and basophil counts. These cells play a crucial role in your body's immune response and can help fight off the flu virus.

However, it's important to note that while sauna use can boost your immune system, it's not a substitute for a healthy lifestyle and proper medical care. If you have the flu, you should also rest, stay hydrated, and consult your doctor.

Relieving Flu Symptoms

Heat and steam from a sauna can help relieve some flu symptoms. The heat can soothe achy muscles and joints, while the steam can help clear congestion and soothe a sore throat.

A study published in the American Journal of Medicine found that inhaling warm, humid air can improve nasal congestion. While this study didn't specifically look at sauna use, it suggests that the steam from a sauna could potentially help with flu-related congestion.


Sweating in a sauna can help your body detoxify by eliminating toxins through your skin. While your body has its own natural detoxification processes, some believe that sauna use can enhance these processes.

However, it's important to note that the concept of "sweating out toxins" is controversial and not fully supported by scientific evidence. More research is needed in this area.

Precautions and Considerations

While a sauna may have potential benefits for the flu, it's also important to consider the potential risks and precautions.

Dehydration and Overheating

Using a sauna can lead to dehydration and overheating, which can be dangerous, especially if you're already sick with the flu. The flu can cause dehydration, and using a sauna can exacerbate this. It's important to drink plenty of fluids before and after using a sauna.

Overheating can also be a risk, especially for those with heart conditions. If you feel dizzy, nauseous, or uncomfortable in any way while in the sauna, it's important to get out immediately.

Consult Your Doctor

Before using a sauna for the flu, it's important to consult your doctor, especially if you have a chronic condition or are pregnant. While a sauna can have potential benefits, it's not suitable for everyone and can have risks.


So, could a sauna help with the flu? The answer is possibly. Research suggests that a sauna can boost your immune system, relieve flu symptoms, and potentially help your body detoxify. However, it's also important to consider the potential risks and precautions, such as dehydration and overheating.

Remember, while a sauna can potentially support your body's fight against the flu, it's not a substitute for a healthy lifestyle, proper hydration, rest, and medical care. Always consult your doctor before starting any new health regimen, especially if you're sick with the flu.
