Lots of people enjoy using infrared saunas for their relaxation and health benefits. But if you’re someone concerned about skin health, you may find yourself wondering, do infrared saunas cause skin cancer? This is a valid question, especially with all the information—and misinformation—out there. While infrared saunas offer a way to sweat out toxins and relieve stress, it’s essential to understand their effect on your skin. So, do infrared saunas cause skin cancer? We’re going to look at the science and address these concerns.
Let’s clarify what infrared saunas are and how they differ from traditional saunas. Understanding these distinctions will provide context for our discussion about potential risks.

What is an Infrared Sauna?
Unlike traditional saunas which heat the air around you, infrared saunas use invisible light waves to penetrate your body directly. These infrared waves are part of the electromagnetic spectrum, like visible light and radio waves. Think of it this way – you feel the warmth of infrared light when you stand near a hot stove but you don’t see it.
There are three types of infrared radiation used in these saunas. They each penetrate to different depths and may have distinct effects:
- Near-Infrared (NIR): The shortest wavelengths, penetrating superficially.
- Mid-Infrared (MIR): Moderate wavelengths, reaching deeper tissues.
- Far-Infrared (FIR): The longest wavelengths, absorbed most efficiently by the body.
Infrared Saunas vs Traditional Saunas: Key Differences
Regular saunas use moist heat or dry heat, with temperatures reaching up to 185°F. This high heat causes your body to sweat by raising the temperature of the surrounding air first. An infrared sauna, on the other hand, operates at a lower temperature range. Typically it’s between 120°F and 140°F. This allows for a more comfortable experience as the infrared light directly warms your body.
Do Infrared Saunas Pose a Risk for Skin Cancer?
Here’s where things get a bit technical, but we’ll keep it easy to understand. Skin cancer primarily occurs from exposure to ultraviolet (UV) radiation, which is also part of the electromagnetic spectrum. We get UV radiation from the sun, and overexposure is known to damage DNA and increase the risk of skin cancer.
So where does infrared radiation fit into this? Some research suggests that high levels of infrared radiation, specifically near-infrared, might cause some skin damage. However, this damage is different from the DNA-altering effects of UV radiation that lead to skin cancer. This difference in effect makes it highly improbable for infrared saunas to directly cause skin cancer.
Understanding Infrared’s Effects on the Skin
While the risk of infrared radiation leading to skin cancer is very low, that doesn’t mean it has no effect on your skin. As mentioned, high amounts of near-infrared radiation, especially alongside exposure to UV and visible light, can contribute to some damage.
For example, a 2005 study shows a link between intense NIR and accelerated aging in mice skin. Some negative effects included wrinkles and collagen breakdown. This effect is known as “photoaging,” essentially aging brought on by light exposure, similar to what we experience from excessive sun exposure.
This same study in mice did point towards a potential increase in the risk of cataracts from long-term, high-intensity infrared exposure. Cataracts occur when the lens of your eye becomes cloudy, affecting vision. However, infrared radiation doesn’t always equal bad news for your skin.
A 2020 study confirms that it doesn’t directly cause skin cancer. This may seem contradictory to the findings of the 2005 study but remember, a crucial factor in these effects is intensity. Those studies utilized high-intensity IR setups, unlike a standard infrared sauna session.
Do Infrared Saunas Promote Skin Healing?
It may seem like an oxymoron but some evidence shows potential skin-healing benefits from low doses of infrared radiation. That’s right – we’re talking about controlled exposure similar to what’s found in infrared saunas.
Scientists have termed this use of low-level radiation “low-level light therapy (LLLT).” LLLT has shown positive results in accelerating wound healing and reducing skin inflammation. There is also a potential for LLLT to even treat acne or precancerous patches of skin. While these claims might sound exciting, remember that we still need more solid scientific evidence.
Additionally, a fascinating point arises from a 2009 article by Barolet et al, published in Lasers Surg Med link to source. Using a lab model of human skin, this research highlighted how lower doses of red and infrared light might help decrease the breakdown of collagen (the protein that gives skin elasticity), ultimately working against those pesky wrinkles. Again, it’s essential to recognize these are early-stage findings and warrant more rigorous study. If you find conflicting opinions about infrared saunas and skin cancer, the key difference boils down to irradiance.
Think of it as a matter of intensity. It’s about how concentrated that invisible infrared light is. When the intensity is cranked up—like in those scientific studies where they were basically blasting skin cells—you might indeed see damage. Erythema ab igne is a skin condition that can be caused by long-term exposure to infrared radiation, but again, this is different from skin cancer.
Think of it as a spectrum; high intensity could lead to harm while a carefully regulated dose of this invisible light shows promise in benefiting the skin. We still need further investigation into the long-term effects of infrared saunas to be sure of their complete safety profile.
Using Infrared Saunas Responsibly
Let’s be clear, using infrared saunas safely for potential benefits is crucial. Before hopping into an infrared sauna, especially if you have existing skin concerns or medical conditions, talk to your doctor. Just like everything in life, moderation is key when using infrared saunas. Keep these recommendations in mind for responsible use:
| Safety Tips for Using Infrared Saunas |
|---|
| Consult a medical professional to check if saunas are suitable, especially with health issues. |
| Start slow; begin with short sessions at lower temperatures, gradually increasing as tolerated. |
| Listen to your body; take breaks, exit the sauna, and stay hydrated during and after your sessions. |
| Consider using eye protection if your sauna has a strong near-infrared emitter, as extended exposure might be associated with cataracts. |
Stay informed, take care of your body, and prioritize responsible practices for safe infrared sauna use. Remember, paying attention to how your body feels is essential. If you experience any unusual skin reactions after using an infrared sauna, discontinue use and consult a healthcare professional.
Other Questions People Have:
Can Infrared Heat Cause Skin Cancer?
Based on current research, infrared heat itself does not directly cause skin cancer. UV radiation, a different type of radiation from the sun, is the main culprit behind most cases.
Are Infrared Saunas Bad for Your Skin?
While high doses of infrared radiation (especially NIR) have shown some skin-damaging effects in studies, standard infrared saunas operate at much lower levels. Excessive heat can dry out your skin so moisturizing is advised.
Are There Any Dangers to Infrared Saunas?
If used improperly or excessively, infrared saunas can lead to dehydration, overheating, and even burns. Certain medical conditions might make them unsafe. Consult your doctor beforehand.
Are There Health Warnings for Infrared Saunas?
People with heart conditions, high blood pressure, diabetes, or certain skin conditions should exercise caution. Always follow the sauna manufacturer’s guidelines, listen to your body, and avoid prolonged use.
So, back to the burning question—do infrared saunas cause skin cancer? The current understanding points to no. However, responsible use is crucial for minimizing any potential for skin-damaging effects. Infrared saunas emit non-ionizing radiation, unlike the ionizing radiation that is known to cause DNA damage.
Like with most wellness practices, listen to your body, start slowly, stay hydrated, and talk with your doctor, especially if you have health concerns. Knowledge is power, so remember to prioritize sensible use when considering whether or not “do infrared saunas cause skin cancer.” Informed decisions are healthy decisions.
