What Are Infrared Saunas and How Do They Work?

Unlike traditional saunas that heat the air to 150°F–195°F (65°C–90°C), infrared saunas use infrared lamps to emit light that warms your body directly. Operating at 120°F–140°F (49°C–60°C), they’re gentler yet still induce a deep sweat. This “resonant heat effect” penetrates tissues, potentially boosting circulation and relaxation.

The science is fascinating: infrared light targets your body, not the air, making it feel like a warm hug rather than a stifling oven. Want to dive deeper into the mechanics? Our page on what is an infrared sauna explains it all.

Health Benefits of Infrared Saunas

Infrared saunas are celebrated for their potential health perks, backed by research:

Heart Health: A study in the Journal of the American College of Cardiology found that regular sauna use improved blood vessel function in people with heart risk factors, potentially lowering blood pressure.
Pain Relief: The deep heat can ease chronic pain, like arthritis, by relaxing muscles and reducing inflammation, as noted in a Psychotherapy and Psychosomatics study.
Stress Reduction: Saunas promote relaxation, lowering stress hormones. Many love them post-workout for muscle recovery—learn more about the benefits of a sauna after exercise.
Detoxification: While the liver and kidneys handle most detox, sweating may help remove small amounts of toxins, per an Archives of Environmental Contamination and Toxicology study.

Are Infrared Saunas Safe? Understanding the Risks

Research, such as a Canadian Family Physician review, suggests infrared saunas are safe for most when used correctly, with no reported adverse effects in multiple studies. However, potential risks include:

Dehydration: Sweating can deplete fluids, leading to dizziness or low blood pressure. Drink water before, during (if allowed), and after sessions.
Overheating: Prolonged exposure may cause heat exhaustion or stroke, with symptoms like nausea or rapid heartbeat. Exit immediately if you feel unwell.
Skin Irritation: Sensitive skin may react to heat, causing redness or burns. Start with lower temperatures.
Cardiovascular Strain: Heat increases heart rate, which may stress those with heart conditions. Consult a doctor first.
EMF Concerns: Some devices, especially infrared sauna blankets, may emit electromagnetic fields. Choose low-EMF models to minimize theoretical risks.
Cancer Myths: No evidence links infrared saunas to cancer, despite online fears. Their non-ionizing radiation doesn’t damage DNA, unlike UV rays.

Special Considerations for Infrared Sauna Blankets

Infrared sauna blankets offer portability but come with unique concerns:

EMF Exposure: Blankets may emit higher EMF due to close skin contact. Opt for low-EMF certified products.
Material Safety: Some blankets use polyurethane, which may release gases when heated. Choose BPA-free, non-toxic materials.

Safety Guidelines for Using Infrared Saunas

To enjoy infrared saunas safely:

Start Slow: Begin with 10–15-minute sessions at 120°F (49°C), increasing gradually.
Stay Hydrated: Bring water into the sauna and drink plenty afterward. Electrolyte drinks can help.
Listen to Your Body: Feeling dizzy? Get out and cool down.
