Are Infrared Saunas Actually Safe?
For most healthy adults, infrared sauna use is generally safe when sessions are kept within recommended limits. However, individual health conditions and medications can affect how the body responds to heat.
Before choosing an infrared sauna, it helps to look beyond its heating performance and consider its safety features. From EMF levels and electrical safety certifications to proper usage guidelines, these details can help you compare products and understand what to look for in a sauna that suits your needs.
"The key to a comfortable infrared sauna experience is to start slowly, stay hydrated, and pay attention to how your body responds to the heat. There is no need to push through discomfort to get the most out of a session."
- Ryan Williams, Sauna Expert at SaunaHeaters.com
What Does the Research Say About Infrared Sauna Safety?
A 2018 systematic review by Hussain and Cohen found that the clinical sauna studies they examined reported no major safety concerns. Infrared saunas typically operate at 120°F to 150°F, compared with approximately 160°F to 200°F for traditional saunas. These lower temperatures may make infrared sessions easier for some people to tolerate.
Still, infrared sauna side effects can occur, especially when sessions last too long or hydration is inadequate. Common issues include:
- Dehydration: Sweating causes fluid loss, particularly when you do not drink enough water.
- Light-headedness: Heat can cause dizziness, especially during prolonged sessions.
- Temporary drops in blood pressure: Heat widens blood vessels and can lower blood pressure.
These effects are often manageable with sensible precautions. However, persistent or severe symptoms should not be ignored. The known infrared sauna dangers are generally manageable for healthy adults, but individual health conditions can change the risk.
Who Should Be Cautious About Infrared Sauna Use?
Infrared saunas are not suitable for everyone. Some people should avoid them, while others need medical advice before their first session.
- Pregnant women: Medical guidance generally recommends avoiding saunas during pregnancy because the safety of heat exposure is not well established.
- People with uncontrolled heart conditions: Arrhythmias, unstable angina, and a recent heart attack require medical assessment before sauna use.
- People taking blood pressure medication or diuretics: Heat exposure may increase the risk of dehydration or an unsafe drop in blood pressure.
- People with open wounds or recent surgery: Wait until healing is complete and obtain medical clearance when necessary.
- Children: Young children should not use infrared saunas. Older children require appropriate adult supervision and shorter sessions.
- Anyone feeling unwell during a session: Dizziness, nausea, or faintness means the session should stop immediately.
If you have an existing medical condition or take prescription medication, check with your doctor before your first session. A quick medical consultation can help you make a safer, more informed decision.
Are Infrared Saunas Safe From EMF?
Electromagnetic fields (EMF) are a common concern when shopping for an infrared sauna. These fields are produced by electrical components, including the heating panels used in infrared saunas. However, their presence alone does not mean a product is unsafe.
Research has not established that low-level EMF exposure within applicable safety guidelines causes harm, although research continues. Therefore, it is better to check independent test results than rely on broad claims that a sauna is completely harmless.
SaunaHeaters.com carries products designed to address EMF concerns, including:
- Golden Designs PureTech panels: Reported EMF levels below 3 milligauss (mG).
- Finnmark Spectrum Plus panels: Tested by NTS, providing additional product-specific testing information.
Before buying, ask for independent EMF test documentation and check the distance at which measurements were taken.
What Benefits Can You Expect From Regular Use?
Understanding infrared sauna benefits and risks means looking at potential benefits without treating them as guaranteed health outcomes. Research suggests that sauna bathing may support relaxation and cardiovascular health, although results vary.
Pain Relief and Muscle Recovery
Infrared heat may help relax tight muscles and ease stiffness after physical activity. Some people also use sauna sessions as part of their routine for managing muscle and joint discomfort. For persistent pain, consult a healthcare professional.
Better Sleep
Many sauna users report better sleep after sessions. The warmth and relaxation may help the body wind down before bedtime, although individual results differ.
Stress Reduction
A warm, quiet sauna session can provide time to relax and unwind. Regular use may help some people manage everyday tension, but it should not replace professional care for ongoing stress or mental health concerns.
Improved Circulation
Heat causes blood vessels to widen, temporarily increasing blood flow. Sauna bathing may support cardiovascular health, but it should not replace exercise or prescribed treatment.
A Manageable Wellness Routine
For healthy adults, infrared saunas can be a relatively gentle way to incorporate heat exposure into a wellness routine. Still, they carry risks, particularly when sessions are too long or users have underlying health conditions.
How to Use an Infrared Sauna Safely
Following a few basic precautions can help reduce infrared sauna risks and make sessions more comfortable.
- Start with a lower temperature and shorter sessions, then gradually increase them as your body adjusts to the heat.
- Drink water before, during, and after each session.
- Avoid sauna use after drinking alcohol, as it can increase dehydration and impair your response to heat.
- Leave immediately if you feel dizzy, nauseous, or faint. Cool down and hydrate.
- Sit on a towel to absorb sweat and keep the sauna clean.
- Wait at least two hours after a large meal before a session.
- Ask your doctor about possible interactions if you take medication.
- Choose a manufacturer that provides independent EMF test results and electrical safety documentation.
