Are Infrared Saunas Safe

Are Infrared Saunas Safe? Potential Risks Explained

Table of Contents

In recent years, infrared saunas have gained popularity as a relaxation and recovery tool. Proponents of infrared saunas claim numerous health benefits, including improved cardiovascular health, reduced pain and fatigue, and even weight loss.2 However, it is important to understand the potential risks associated with infrared sauna use and evaluate the safety of these devices.

What are Infrared Saunas?

Infrared saunas, also known as far infrared saunas (FIRSs), utilize infrared radiation to heat the body directly. Unlike traditional saunas that heat the air to high temperatures, FIRSs heat the body with infrared rays, which penetrate the skin and promote a deep sweat at lower temperatures.1 This makes the experience more comfortable and relaxing for many users.

Infrared sauna use involves exposure to infrared light and infrared radiation, which can penetrate the skin more deeply than the heat in a traditional sauna. This far infrared technology is not only used in saunas but also in products like infrared sauna blankets. While sauna bathing in a traditional sauna is a well-known practice, using an infrared sauna or infrared sauna blankets offers a different experience due to the infrared therapy involved.

The infrared spectrum is divided into three categories: IR-A, IR-B, and IR-C. FIRSs primarily emit IR-A and IR-B wavelengths, which are believed to have therapeutic effects on the body. The infrared heat from FIRSs can penetrate deeper into the skin compared to traditional saunas, potentially providing additional benefits for circulation, muscle repair, and pain relief.2

The Growing Popularity of Infrared Saunas

The popularity of infrared sauna use has grown significantly in recent years, with many individuals incorporating them into their wellness routines. The market for FIRSs is valued at millions of dollars and continues to expand rapidly. Manufacturers promote the health benefits of FIRSs, and these devices are often sold to the public as recreational saunas.4

However, it's essential to approach the claims made by manufacturers with caution. While some studies support the use of FIRS therapy for certain conditions, the overall scientific evidence is limited, and more research is needed to substantiate these claims fully.4

Potential Negative Side Effects of Infrared Saunas

While infrared saunas are generally considered safe for most individuals, there are potential risks and side effects associated with their use. It's crucial to be aware of how often you should use an infrared sauna and the potential risks in order to take necessary precautions and ensure a safe and enjoyable sauna experience.

  • Dehydration: Sauna sessions, including those in far infrared saunas, can lead to excessive sweating and loss of fluids. It is essential to stay hydrated before, during, and after sauna use. Drinking water or electrolyte-rich beverages can help replenish lost fluids and prevent dehydration.
  • Overheating: Infrared saunas emit heat, which can raise the body's temperature. It is important to monitor your body's response to the heat and avoid prolonged or excessive sauna sessions. If you start feeling lightheaded, dizzy, or nauseous, it is recommended to leave the sauna and cool down.
  • Cardiovascular Strain: Sauna use, including infrared saunas, can increase heart rate and blood pressure. While these effects are generally well-tolerated by healthy individuals, people with pre-existing cardiovascular conditions should consult with their healthcare provider before using an infrared sauna. Individuals with unstable angina, recent heart attack, or severe aortic stenosis should avoid sauna use altogether.2
  • Heat-related Illnesses: Prolonged exposure to high temperatures in saunas can increase the risk of heat-related illnesses, such as heat exhaustion or heatstroke.1 It is crucial to listen to your body and exit the sauna if you experience symptoms such as dizziness, headache, rapid heartbeat, or confusion. If these symptoms persist or worsen, seek medical attention immediately.
  • Skin Sensitivity:Some individuals may experience skin sensitivity or irritation from the heat and infrared radiation in saunas. It is recommended to start with shorter sauna sessions and gradually increase the duration as your body acclimates. If you have a pre-existing skin condition or are prone to skin allergies, consult with a dermatologist before using an infrared sauna.
  • Eye Damage: Direct exposure of the eyes to infrared radiation can cause eye damage. It is crucial to protect your eyes by keeping them closed or using protective eyewear specifically designed for sauna use. Avoid looking directly at the infrared emitters or lamps. Consider learning more about what to wear in infrared saunas before beginning.
  • Pregnancy: Pregnant women should consult with their healthcare provider before using an infrared sauna. The increased body temperature from sauna use may pose risks to the developing fetus. It is generally recommended to avoid using saunas during pregnancy to ensure the safety of both the mother and the baby.

Who Shouldn't Use Infrared Saunas?

While the many types of infrared saunas can provide relaxation and potential health benefits, certain individuals should exercise caution or avoid using them altogether. This includes:

  • Individuals with cardiovascular conditions, such as unstable angina, recent heart attack, or severe aortic stenosis.
  • Pregnant women or those trying to conceive.
  • Individuals with a history of heat-related illnesses or difficulty regulating body temperature.
  • Individuals with skin conditions or allergies that may be aggravated by heat or infrared radiation.
  • Individuals taking medications that affect blood pressure or heart rate, as sauna use can impact these physiological parameters.

If you have any underlying health conditions or concerns, it is always best to consult with your healthcare provider before using an infrared sauna.

Tips for Properly Using Infrared Saunas

To ensure a safe and enjoyable sauna experience, follow these tips:

  • Stay hydrated: Drink plenty of water or electrolyte-rich beverages before, during, and after sauna sessions to prevent dehydration.
  • Limit session duration: Start with shorter sessions and gradually increase the duration as your body acclimates to the heat. Avoid prolonged sauna sessions to prevent overheating.
  • Listen to your body: Pay attention to any signs of discomfort, dizziness, or lightheadedness. If you experience these symptoms, exit the sauna and cool down.
  • Protect your eyes: Keep your eyes closed or use protective eyewear designed for sauna use to prevent eye damage from direct exposure to infrared radiation.
  • Seek medical advice: If you have any underlying health conditions or concerns, consult with your healthcare provider before using an infrared sauna to ensure it is safe for you.
