Infrared Sauna: Why the Infrared Saunas Are the Smarter Way to Sweat
There’s something timeless about the ritual of sweating it out — from ancient Roman baths to Scandinavian saunas, cultures across history have turned to heat for healing. But today’s wellness landscape offers a modern upgrade: the infrared sauna. At ReGen Rooms in Leamington Spa, our clients are discovering the benefits of this deeply restorative therapy and unlike traditional saunas, it’s not just about getting hot and sweaty.
Infrared saunas offer a full-body detox experience that works at the cellular level. The heat you feel is only part of the story. The science behind it reveals something far more profound.
What Makes Infrared Different?
Traditional saunas heat the air around you, which in turn heats your body. It’s an ambient warmth that can sometimes feel overwhelming, especially for those sensitive to high temperatures. Infrared saunas work differently. They use invisible light wavelengths — specifically far-infrared light — to gently penetrate beneath the skin and heat your body directly.
This means you get the benefits of a deep, therapeutic sweat without the stifling heat. Temperatures in infrared saunas are typically around 45–60°C, compared to 80–100°C in a standard sauna, making it much more comfortable to stay in longer and more accessible for those new to heat therapy.
But comfort is only the beginning.
Why We Use Sunlighten — The Gold Standard in Infrared Therapy
At ReGen Rooms, we’ve chosen to use Sunlighten saunas who are widely regarded as the gold standard in infrared therapy. These state-of-the-art cabins use patented SoloCarbon® infrared technology, clinically shown to increase core body temperature and detoxification more effectively than standard infrared units.
Unlike traditional wooden box saunas with uneven heat and high EMF exposure, Sunlighten’s low-EMF systems deliver a consistent, therapeutic wavelength of far, mid, and near-infrared light, allowing for a deeper, more comfortable sweat. It’s not just about heat, it’s about healing with precision and safety.
Sunlighten saunas are trusted by wellness professionals, elite athletes, and luxury spa retreats across the world. By bringing them to Leamington Spa, we’re offering our clients the very best in modern detox and relaxation — all within a calm, private setting at ReGen Rooms.
Deep sweat, deeper benefits — infrared sauna therapy encourages muscle recovery and full-body detox.
A Science-Backed Detox
One of the most compelling reasons to try infrared therapy is its impact on detoxification. Unlike surface-level sweating during a workout, the sweat produced during infrared therapy is shown to contain more heavy metals, BPA, and environmental toxins. This is because the heat penetrates up to 1.5 inches below the skin, stimulating the lymphatic system and encouraging your body to purge what it doesn’t need.
In fact, studies have shown that regular use of infrared saunas can reduce levels of mercury, lead, and other harmful substances stored in the body. A 2012 study published in The Journal of Environmental and Public Health even highlighted infrared saunas as a safe, effective method for assisting people with chronic toxic burden.
It’s no wonder elite athletes and functional medicine practitioners are embracing this therapy and why it’s becoming one of the most sought-after wellness treatments in the UK.
Beyond Detox: The Hidden Benefits
While the word “detox” gets thrown around a lot in wellness spaces, infrared therapy offers far more than a post-Christmas cleanse. Regular sessions can improve circulation, reduce inflammation, aid in weight loss, and even enhance mood. There’s growing evidence that infrared heat increases nitric oxide production, a natural vasodilator that improves blood flow and helps lower blood pressure.
Many clients also report clearer skin, better sleep, and a profound sense of calm after each session. And this isn’t placebo: infrared therapy has been shown to activate the parasympathetic nervous system, the part of your body responsible for rest and recovery.
Interestingly, the benefits even extend to your metabolism. According to a 2009 study published in The Journal of the American Medical Association, a 30-minute infrared session can burn up to 600 calories — similar to moderate exercise — thanks to the body’s effort to regulate its internal temperature.
A Relaxing, Restorative Experience at ReGen Rooms
At ReGen Rooms, our infrared sauna is set within a calming, spa-like environment where you can unplug, recharge, and give your body space to heal. Whether you're recovering from a tough workout, managing stress, or simply looking to prioritise your health, this treatment fits seamlessly into a modern wellness routine.
Unlike many spa saunas, ours is equipped with low-EMF infrared panels, ensuring a clean, safe experience that aligns with the latest in scientific research and holistic health.
Before your session, we’ll walk you through the process, help you feel at ease, and offer hydration support so you leave feeling fully refreshed - not drained.
What to Expect
Most sessions last around 30 minutes, but the effects can last much longer. You’ll begin to sweat within the first 10 minutes as your body responds to the gentle heat. Many clients describe it as a “warm, internal hug”, soothing but powerful.
We recommend drinking plenty of water before and after, and wearing light, breathable clothing. If it’s your first time, don’t worry. You’re in safe hands and you might be surprised at just how good you feel afterwards.
