Are Infrared Saunas Safe To Use?

Let’s talk about the safety of infrared saunas. If you’ve ever wondered whether these saunas are safe to use, you’re not alone. Infrared saunas have gained popularity in recent years, but there are still lingering concerns regarding their safety. In this article, we will explore the potential risks and benefits of infrared sauna use, helping you make an informed decision about incorporating them into your wellness routine.

What are Infrared Saunas?

Definition of Infrared Saunas

Infrared saunas are a type of sauna that uses infrared light to heat the body directly, instead of heating the surrounding air as traditional saunas do. They are designed to deliver the therapeutic benefits of heat therapy in a more targeted and efficient way.

How Infrared Saunas Work

Infrared saunas work by emitting infrared radiation, which is a form of invisible light that heats the body directly. The infrared rays penetrate the skin and gently elevate the body’s core temperature, which triggers a variety of physiological responses. This heat therapy is believed to promote relaxation, detoxification, pain relief, and other health benefits.

Potential Benefits of Infrared Saunas


One of the main potential benefits of infrared saunas is detoxification. When the body is exposed to the heat of an infrared sauna, it sweats, which helps to eliminate toxins and impurities from the body. Sweating is a natural way for the body to cleanse and eliminate waste, and infrared saunas can enhance this process.

Pain Relief

Infrared saunas have been reported to provide pain relief for various conditions. The heat from the sauna can soothe aches and pains in the muscles and joints, providing temporary relief from conditions such as arthritis, fibromyalgia, and muscle soreness. Additionally, the relaxation induced by the sauna can help reduce stress and promote overall well-being, further aiding in pain management.

Improved Circulation

The heat generated by infrared saunas can help improve circulation in the body. As the body heats up, the blood vessels in the skin dilate, allowing for increased blood flow. This increased circulation can help deliver oxygen and nutrients more efficiently to the muscles and organs, promoting overall cardiovascular health.

Weight Loss

While infrared saunas alone are not a magic solution for weight loss, they can aid in the process. The heat from the sauna can cause an increase in heart rate, similar to moderate exercise, which can lead to increased calorie burn. Additionally, sweating in the sauna can help eliminate water weight temporarily. When combined with a healthy diet and regular exercise, infrared saunas can be a valuable tool in a weight loss journey.

Skin Health

Infrared saunas have been praised for their potential benefits to the skin. The increased blood flow and sweating caused by the saunas can help cleanse the skin, unclog pores, and improve overall complexion. Some people have reported improvements in conditions such as acne, eczema, and psoriasis after using infrared saunas regularly.

Relaxation and Stress Relief

Infrared saunas provide a warm and soothing environment, which can promote relaxation and stress relief. The calming atmosphere, coupled with the benefits of heat therapy, can help reduce anxiety, lower stress levels, and improve overall mental well-being. Spending time in an infrared sauna can be a peaceful and rejuvenating experience.

Improved Sleep

Using an infrared sauna can also have a positive impact on sleep quality. The relaxation induced by the sauna can help calm the mind and body, making it easier to fall asleep and achieve a deeper and more restful sleep. By incorporating regular sauna sessions into a bedtime routine, individuals may experience an improvement in their sleep patterns.

Safety Concerns of Infrared Saunas

Excessive Heat Exposure

While infrared saunas are generally safe, it is important to be mindful of excessive heat exposure. Prolonged or intense heat can cause heat stroke or heat exhaustion, especially for individuals who are sensitive to heat or have underlying medical conditions. It is crucial to listen to your body and ensure that you do not spend too much time in the sauna or allow yourself to overheat.


Sweating in the sauna can lead to dehydration if fluids are not replenished adequately. It is essential to drink plenty of water before, during, and after a sauna session to stay hydrated. Avoiding alcohol and caffeinated beverages is also recommended, as they can contribute to dehydration.

Electromagnetic Fields (EMF) Exposure

Some infrared saunas emit electromagnetic fields (EMF), which are a type of radiation. High levels of EMF exposure may pose health risks, although the scientific evidence is still inconclusive. To minimize potential exposure, it is advisable to choose saunas with low EMF emissions or opt for alternative types of infrared saunas that have less EMF output.

Skin Sensitivity

Individuals with sensitive skin may experience redness, itching, or irritation after using an infrared sauna. It is advisable to start with shorter sessions and lower temperatures to test your skin’s reaction. If any discomfort occurs, it is best to discontinue sauna use and consult with a dermatologist.

Pregnancy and Medical Conditions

Pregnant women and individuals with certain medical conditions should consult with their healthcare provider before using an infrared sauna. The heat from the sauna can potentially be harmful to the developing fetus or may exacerbate certain medical conditions. It is crucial to prioritize safety and seek medical advice if there are any concerns.


While regular sauna sessions can provide benefits, overuse can have negative effects on the body. It is important to follow the recommended guidelines for session duration and temperature settings. Overuse of an infrared sauna can lead to dehydration, exhaustion, and potentially strain the cardiovascular system. Moderation is key to ensuring a safe and beneficial sauna experience.

Different Types of Infrared Saunas

Traditional Infrared Saunas

Traditional infrared saunas are typically installed in a fixed location, such as a home, gym, or wellness center. They often resemble small wooden rooms with built-in infrared heaters. These saunas provide a relaxing and spa-like experience, offering the benefits of heat therapy in a controlled environment.

Infrared Blankets

Infrared blankets are a portable and convenient option for heat therapy. They consist of a blanket or mat equipped with infrared heating elements. Users can wrap themselves in the blanket or lie on the mat to experience the benefits of infrared heat. Infrared blankets are an accessible option for those who prefer the flexibility of being able to use them anywhere in their home.

Portable Infrared Saunas

Portable infrared saunas are compact units that can be easily set up and used in different locations. They typically resemble a tent or small cabin and have infrared heating panels inside. Portable saunas are a popular choice for individuals who want the convenience of having their sauna in various rooms or taking it with them when traveling.

Tips for Using Infrared Saunas Safely

Stay Hydrated

As mentioned earlier, it is crucial to stay hydrated before, during, and after using an infrared sauna. Drink plenty of water to replenish the fluids lost through sweating and prevent dehydration. Hydration is a key factor in ensuring a safe and enjoyable sauna experience.

Limit Session Duration

Start with shorter sauna sessions, typically around 10-15 minutes, and gradually increase the duration as your body becomes acclimated. The recommended maximum sauna session duration is usually around 30 minutes. It is essential to listen to your body and exit the sauna if you feel lightheaded, dizzy, or uncomfortable.

With proper precautions, such as staying hydrated, limiting session duration, and considering individual health needs, individuals can enjoy the potential benefits of infrared saunas while minimizing any potential risks or concerns. Remember to consult with a healthcare professional if you have any underlying medical conditions or are unsure if infrared sauna use is appropriate for you. By using infrared saunas responsibly, you can create a soothing and rejuvenating experience for your mind, body, and overall well-being.
