What Is Infrared Therapy?

Discover the Healing Power Behind Modern Infrared Saunas

Infrared therapy is an advanced wellness treatment that uses infrared light to gently warm the body from within. Unlike visible light, infrared light sits just beyond the visible spectrum—but we feel it as heat. This energy interacts with the water molecules in our bodies, promoting a natural response that supports healing, relaxation, and overall wellbeing.

Infrared therapy has been used for centuries to aid various health conditions. In recent years, it has gained popularity across the UK as a modern and effective way to enhance physical and mental wellness. Rest assured, infrared radiation is non-ionising—completely safe and free from the risks associated with harmful UV or X-ray exposure.

Benefits of Infrared Therapy

Infrared saunas provide a wide range of health benefits, making them a popular choice for those looking to invest in home wellness. Some of the most well-documented effects include:

  • Enhanced circulation

  • Reduced inflammation

  • Lower blood pressure

  • Boosted metabolism

  • Improved detoxification

  • Accelerated recovery and wound healing

  • Weight loss support

  • Pain relief

  • Deeper, more restful sleep

  • Stress and anxiety reduction

Many people in the UK combine infrared sauna therapy with other wellness practices such as massage, red light therapy, halotherapy, or acupuncture for even greater results.

How Does Infrared Therapy Work?

Infrared waves penetrate beneath the skin's surface, gently heating the body from the inside out. This process raises your core temperature, improving blood flow, increasing heart rate, and activating your body’s natural detox mechanisms.

At the cellular level, infrared heat helps break down fat cells through a process called lipolysis, converting stored triglycerides into fatty acids and glycerol, which your body then eliminates.

Over time, regular use of infrared saunas can contribute to significant health improvements. For example, a UK-based study found that participants using Clearlight Infrared Saunas three times a week for 30 minutes each lost 4% body fat over four months.

Is Infrared Therapy Safe?

Yes, infrared therapy is completely safe when used correctly. The term "radiation" may sound alarming, but in this case, it refers only to the harmless infrared wavelengths naturally emitted by sources like the sun, fire, and even the human body itself.

Clearlight Saunas use carefully calibrated far infrared technology that’s so gentle, it’s even used in hospitals to keep newborns warm. Unlike UV rays or X-rays, infrared light doesn’t damage cells or tissues—it simply provides therapeutic heat.

That said, if you're pregnant, have a serious medical condition, or have metal implants, we recommend consulting your GP before starting infrared therapy.

Infrared Sauna vs Traditional Sauna – Which Is Better?

While traditional saunas heat the air around you, infrared saunas heat your body directly. This allows for a lower ambient temperature—typically between 45°C and 65°C—making infrared sessions far more comfortable, especially for those who find conventional saunas too intense.

Additional advantages of infrared saunas include:

  • Deeper tissue penetration

  • Targeted fat and toxin release

  • Enhanced metabolic rate

  • Less oppressive heat and easier breathing

For those in the UK looking for a modern, comfortable, and effective home sauna solution, infrared saunas are a superior choice.

Why Heater Placement Matters

At Clearlight UK, our infrared saunas are designed for maximum therapeutic efficiency. We use a strategic combination of ceramic and carbon heaters, placed to evenly target both your front and back core.

Our exclusive True Wave™ heating system ensures full-body coverage, deeper heat penetration, and a consistent temperature throughout your session. The result? A luxurious, revitalising experience that enhances detoxification, reduces tension, and supports long-term wellbeing.

Why Choose Infrared Technology for Your Home Sauna?

Infrared saunas are backed by science, including research from NASA. These waves can penetrate up to 2 inches beneath the skin, delivering heat where it’s most effective—deep in the muscles, joints, and tissues.

While traditional saunas depend on ambient air temperature to induce sweating, infrared heat raises your core temperature from the inside, offering greater health benefits with less strain.

Whether you're seeking a luxury home sauna in the UK, looking to improve your health naturally, or creating a serene spa space in your home, Clearlight Infrared Saunas deliver unmatched quality, comfort, and results.
