Infrared saunas have gained popularity for their relaxing experience and perceived health benefits. But as their use becomes more widespread, so do concerns—especially around whether the exposure could result in cancer or lead to skin damage.
In this article, we’ll dive into the relationship between this type of heat-based therapy and cancer risk, examine common misconceptions, and explain how to use it safely and effectively.
Understanding Infrared Saunas and How They Work
Unlike traditional saunas that heat the air around you, an infrared sauna uses light to warm the body directly. This heat penetrates the skin and warms the body from within, encouraging sweating at lower temperatures than conventional sauna bathing. The effect is achieved through radiation, which operates in the non-ionizing portion of the electromagnetic spectrum.
This may feature near, mid, or far wavelengths. A full-spectrum sauna combines all three for a broader range of effects. The far sauna is the most commonly used type, praised for its deep tissue penetration and gentle heat.
Wellness centers also offer alternative light-based therapies—such as infrared bed therapy—that provide similar benefits to sauna sessions. These beds use targeted wavelengths of light to support circulation, reduce tension, and promote cellular recovery. This non-invasive modality is among the advanced therapeutic services offered at wellness-focused facilities.
Infrared Radiation vs. Cancer Causing UV Rays
A major concern is whether regular sauna use can cause cancer. To answer this, it helps to understand the type of energy it emits. The radiation is non-ionizing, meaning it does not have enough energy to cause DNA damage—a key factor in cancer formation.
Unlike ultraviolet radiation, which can mutate skin cells and lead to skin cancer, infrared light does not carry the same risks.
While heat exposure does affect the human skin, it does not lead to cellular mutations the way UV exposure does. Using this sauna may cause temporary redness or dryness in sensitive individuals, but these effects are not linked to an increased risk of cancer development.
Misconceptions About Infrared Sauna Dangers
Despite the lack of scientific backing, some believe that using a light-based sauna therapy could lead to health issues. These concerns are often based on confusion between infrared and ultraviolet radiation. It is ultraviolet light that has been linked to causing skin cancer.
Other concerns include the perceived dangers of near-light exposure.. While near light penetrates the skin less deeply than far wavelengths, both forms fall within the safe, non-ionizing range of the spectrum. Used correctly, neither near nor far exposure poses a cancer risk.
It’s also worth noting that the dangers often refer to general heat-related risks like dehydration or dizziness, not cancer. When users follow safe sauna practices, these risks are easily managed.
Infrared Saunas and Cancer Patients: What to Know
Infrared sauna therapy is sometimes used by cancer patients seeking complementary support for symptoms like fatigue or pain. While this should never replace medical treatment, many cancer patients report feeling better after regular sessions. It may help reduce discomfort, improve circulation, and promote relaxation.
However, this does not mean it can help prevent cancer or treat cancer cells. The role of these saunas in oncology remains limited to supportive care under medical guidance. People with cancer should always consult a physician before starting any sauna sessions.
Potential Benefits of Infrared Sauna Therapy
Many turn to infrared sauna therapy for its potential health benefits. Studies report that this may help with muscle recovery, stress reduction, improved skin appearance, and enhanced circulation. Unlike traditional saunas, these saunas heat the body more gently by warming tissues directly, which can be more comfortable for users sensitive to high heat.
This therapy may also support cardiovascular function, reduce inflammation, and promote better sleep quality. Regular sessions have been shown to help individuals manage symptoms related to chronic fatigue and joint discomfort. Some users also experience improved mood and reduced tension following consistent use. While individual responses vary, current evidence suggests this therapy is safe for most people when used properly.
How to Use Infrared Saunas Safely
To enjoy the benefits of infrared saunas safely, it is important to follow basic guidelines. Sessions should last 20 to 30 minutes. Drink plenty of water before and after your session to prevent dehydration. Avoid use if you have certain health conditions, such as uncontrolled blood pressure or open wounds.
If you are pregnant or undergoing treatment for a chronic illness, consult a healthcare provider before beginning the sauna therapy. Use it safely by paying attention to how your body responds.
Infrared saunas operate at much lower temperatures than regular saunas, making them accessible to more people. When used responsibly, they offer a low-risk, high-reward wellness tool.
