Sauna When You're Sick: Learn the Benefits & Risks

The use of saunas has been a popular practice for centuries, offering a unique combination of relaxation and health benefits. But what happens when you're feeling under the weather? Is it safe and beneficial to use a sauna when you're sick? This article explores the benefits and risks of using a sauna when you're not feeling well, backed by scientific evidence and research. Remember, everyone's body reacts differently, so it's essential to consult your doctor before starting any new health regimen, including sauna therapy.

The Science Behind Saunas

The use of saunas for health purposes dates back to ancient civilizations, with the practice being a staple in cultures like Finland and Russia. But what is it about saunas that make them so beneficial? The answer lies in the heat. When you sit in a sauna, your body temperature rises, and in response, your blood vessels dilate, increasing blood flow throughout the body. This process, known as vasodilation, can have a variety of health benefits.

Research has shown that regular sauna use can help reduce the risk of cardiovascular diseases, improve lung function, and even enhance mood and mental health. However, it's important to note that these benefits are typically associated with regular, long-term sauna use. The effects of a single sauna session, especially when you're sick, may be different.

Benefits of Using a Sauna When You're Sick

When you're feeling unwell, your body is fighting off an infection or illness. Using a sauna can potentially aid this process in several ways.

Increased Blood Flow

As mentioned earlier, one of the primary effects of sauna use is increased blood flow due to vasodilation. This enhanced circulation can help deliver nutrients and oxygen to your cells more efficiently, aiding your immune system in its fight against illness.

Moreover, the heat from the sauna can also help soothe aching muscles and joints, which can be particularly beneficial if your illness has left you feeling achy and fatigued.

Improved Respiratory Function

Research has shown that sauna use can improve lung function, which can be particularly beneficial if you're suffering from a respiratory illness like a cold or the flu. The warm, moist air can help loosen mucus in the lungs, making it easier to breathe.

However, it's important to note that while sauna use can potentially alleviate some respiratory symptoms, it's not a cure for respiratory illnesses. Always consult your doctor for appropriate treatment options if you're suffering from a respiratory illness.

Risks of Using a Sauna When You're Sick

While there are potential benefits to using a sauna when you're sick, there are also risks to consider. It's important to listen to your body and consult your doctor before using a sauna when you're unwell.


One of the primary risks of using a sauna, especially when you're sick, is dehydration. The intense heat can cause you to sweat profusely, leading to a loss of fluids. If you're already dehydrated due to illness, this can potentially worsen your condition.

To mitigate this risk, it's crucial to stay hydrated before, during, and after your sauna session. Drink plenty of water and consider replenishing electrolytes if you're sweating heavily.


Another risk to consider is overheating. If you're already running a fever, using a sauna can potentially raise your body temperature to dangerous levels. This can lead to heat exhaustion or, in severe cases, heat stroke.

Always monitor your body's response to the heat and exit the sauna if you start to feel dizzy, nauseous, or overly fatigued. It's better to err on the side of caution when it comes to your health.


Using a sauna when you're sick can potentially offer benefits like increased blood flow and improved respiratory function. However, it's crucial to be aware of the risks, such as dehydration and overheating. Always consult your doctor before using a sauna when you're unwell, and listen to your body's responses to the heat.

Remember, everyone's body is different, and what works for one person may not work for another. Sauna use is just one tool in the toolbox for overall health and wellness, and it's important to find what works best for you.
