Jan 15, 2022


Saunas have been around for centuries, with the Finnish culture being one of the pioneers in using heat to improve health and well-being. The word "sauna" actually comes from Finnish, and it means a small room or hut where one can experience high heat and humidity.

Nowadays, saunas are gaining popularity worldwide, not only as a relaxation tool but also as a way to boost health and longevity. In this article, we will explore the history and science of saunas, the different types and their specific benefits, as well as the potential risks and limitations of sauna use. We will also provide evidence-based tips and recommendations for safely and effectively using saunas to promote health and longevity.

The History and Science of Saunas

The use of heat for healing and wellness purposes has been documented throughout history. Many cultures, from the Greeks and Romans to the Native Americans and Russians, have used saunas in some form. However, the Finnish sauna is perhaps the most famous and widely used type of sauna in the world.

Studies have shown that regular sauna use has numerous benefits for overall health and longevity. These benefits include improved cardiovascular function, detoxification, relaxation, and even reduced risk of chronic diseases such as Alzheimer's and certain types of cancer. The heat generated in saunas can also help reduce inflammation and improve circulation, which can aid in muscle recovery and wound healing.

Different Types of Saunas and Their Specific Benefits

There are several types of saunas available, each with its own set of benefits. The most common types of saunas include traditional Finnish saunas, infrared saunas, and steam rooms:

  • Traditional Finnish saunas use dry heat generated by burning wood or other materials to heat the air in the room. This type of sauna is known for its detoxifying effects, as sweating helps eliminate toxins from the body. It can also improve cardiovascular function and reduce stress.

  • Infrared saunas use infrared heaters to emit light that penetrates the skin and heats the body directly, rather than heating the air. This type of sauna is popular for its ability to penetrate deeper into the skin, which can promote skin health and improve circulation.

  • Steam rooms use high humidity and moist heat to create a relaxing and soothing environment. This type of sauna can help improve respiratory function, as well as aid in detoxification and relaxation.

Potential Risks and Limitations of Sauna Use

While saunas can have many health benefits, it's important to be aware of potential risks and limitations. For example, people with certain health conditions, such as low blood pressure, heart disease, or asthma, may not be able to tolerate the high heat and humidity of saunas. Additionally, certain medications, such as blood pressure medication, can affect the body's ability to regulate temperature, which can increase the risk of heat-related illness.

It's also important to remember that saunas can cause dehydration, so it's essential to drink plenty of water before, during, and after sauna use. It's also recommended to start with shorter sessions at lower temperatures and gradually increase over time to allow the body to acclimate to the heat.

Tips and Recommendations for Sauna Use

To safely and effectively use saunas to promote health and longevity, follow these evidence-based tips and recommendations:

- Consult with a healthcare provider before using saunas if you have any health concerns or are taking medications.

- Start with shorter sessions at lower temperatures and gradually increase over time.

- Stay hydrated before, during, and after sauna use by drinking water or electrolyte-rich beverages.

- Take breaks as needed and listen to your body's signals.

- Avoid alcohol and other substances that can impair judgment or increase the risk of dehydration.

- Use caution when entering and exiting the sauna to prevent falls or injuries.


Saunas have been used for centuries for their health and wellness benefits, and science has shown that regular sauna use can have many positive effects on the body and mind. However, it's important to be aware of potential risks and limitations, especially for those with certain health conditions or taking medications.

By following evidence-based tips and recommendations, such as gradually increasing temperature and duration, staying hydrated, and seeking medical advice if needed, individuals can safely and effectively use saunas to promote health and longevity.

As with any health and wellness practice, it's essential to listen to your body's signals and take breaks as needed. Saunas can be a relaxing and beneficial addition to a healthy lifestyle, but it's important to use them safely and responsibly.
