The Healthiest Infrared Sauna You Can Buy [No Glue, No Plywood]

Looking for a sauna that heals your body without hidden risks? Many saunas use glue, plywood, and chemicals that release toxins when heated. 

You deserve better. With the right choice, you can enjoy pure heat, deep relaxation, and real health benefits. Let’s explore what makes the healthiest infrared sauna worth your investment.

• Know Your Sauna Types: Dry, infrared, and steam saunas each offer different heat and humidity experiences.
  
  

• Support Your Health: Infrared saunas can boost circulation, aid recovery, and strengthen your immune system.
  
  

• Choose Safe Materials: Avoid plywood, glues, and synthetic finishes that release harmful toxins when heated.
  
  

• Prioritize Low-EMF Design: Look for saunas with ultra-low electromagnetic exposure for added safety.
  
  

• Invest in Purity: Solid wood, chemical-free saunas—like those made with Canadian Hemlock—offer the cleanest and healthiest experience.

Saunas come in several styles, each offering a distinct experience in heat and humidity. As Healthline notes, traditional dry saunas are the hottest, typically ranging from 70 to 90 °C, but they maintain low humidity around 5–10%, producing a dry, intense heat. 

Infrared saunas, by contrast, use infrared light to warm your body directly, creating a much cooler environment, usually between 38 and 65 °C, while still allowing a relaxing sweat. 

Steam saunas, sometimes called wet saunas, focus on high humidity, often between 95% and 100%, but operate at lower temperatures, generally 30 to 50 °C. 

This warm, moist air feels gentle and enveloping, offering a completely different sensation than the sharp dry heat of traditional saunas. 

Understanding these differences, according to Healthline, can help you select a sauna that fits your comfort level and wellness goals, whether you prefer intense heat, gentle infrared warmth, or the soothing embrace of a humid steam room.

Infrared saunas help your body detox by gently raising your core temperature, which makes you sweat and encourages your body to release stored toxins. 

This process can especially target fat-soluble chemicals and heavy metals, helping them leave your system safely. 

For example, according to a PubMed study, longer sauna sessions can enhance this mobilization of toxins, while also supporting heart health and blood flow, making saunas both safe and effective for regular use.

Spending time in an infrared sauna can gently boost your circulation and support heart health. 

The deep, soothing heat penetrates the skin, causing blood vessels to expand and blood flow to increase. 

This process can help reduce stress on the heart and improve oxygen delivery throughout the body. 

According to research summarized by Canadian Family Physician, far-infrared sauna therapy shows moderate evidence for helping normalize blood pressure and supporting those with congestive heart failure. 

Several studies also indicate benefits for people with coronary risk factors. Using an infrared sauna regularly may be a relaxing, heart-friendly way to support your cardiovascular system naturally.

After a tough workout, your muscles need more than just rest, they need deep recovery. Infrared saunas use gentle heat that penetrates 3–4 cm into muscle and fat tissue, helping to relax muscles, reduce soreness, and improve blood flow. 

A study on basketball players found that a single infrared sauna session reduced muscle soreness and helped maintain explosive performance after resistance training. 

Another study showed that far-infrared sauna bathing after strength or endurance workouts boosted recovery, making it a comfortable, low-stress way to help your body bounce back faster.

Infrared sauna heat can help improve skin elasticity and reduce wrinkles by stimulating your skin’s fibroblasts, the cells responsible for producing collagen and elastin. 

When exposed to infrared heat, these cells ramp up production, which strengthens the skin’s structure and smooths fine lines. 

According to a study in the Yonsei Medical Journal, patients who received daily far-infrared treatments for six months reported noticeable improvements in skin texture, roughness, and elasticity. 

Essentially, regular infrared sauna sessions act like a gentle, natural “workout” for your skin, helping it stay firm and youthful.

One of the standout benefits of infrared saunas is stress reduction and deep relaxation. When your body is exposed to gentle heat, it triggers a natural thermoregulatory response, balancing hormones and calming the nervous system. 

Over time, repeated sessions train your body to handle stress better, a phenomenon known as hormesis. 

According to Experimental Gerontology, this mild heat exposure can improve overall well-being, reduce tension, and promote a sense of calm, making sauna time a simple, effective way to recharge both body and mind.

Infrared saunas offer a natural way to strengthen your immune system by gently raising your body’s core temperature, which stimulates white blood cell production and boosts your body’s defenses. 

The heat encourages better circulation, helping your immune system respond faster to infections, while regular sessions can reduce inflammation that often weakens immunity. 

For older adults, infrared saunas provide a safe and effective way to support immune function, keeping the body resilient against seasonal illnesses. 

By promoting detoxification through sweating, these saunas help your immune system stay strong and ready to fight off potential threats.

Using an infrared sauna can help you lose weight by increasing your heart rate and warming your body, which naturally boosts metabolism. 

During a session, your body burns calories, sometimes up to 300 per hour while targeting fat stores, not just water weight. To see real results, aim for regular use, about 3–5 times per week, combined with a balanced diet and exercise plan. 

Infrared sauna sessions complement workouts by improving circulation and supporting recovery, making it easier to stick to healthy routines. 

With consistent use, you can enhance fat burning, raise metabolism, and reach weight-loss goals more effectively.

When it comes to choosing the best wood for a sauna, purity and safety matter just as much as performance. 

Many saunas on the market use plywood, glues, or chemical stains that can release toxins when heated, but Heavenly Heat takes a different approach. 

Our saunas are crafted from FSC-certified Canadian Hemlock, one of the most trusted and durable woods for wellness spaces. 

Canadian Hemlock is naturally strong, non-toxic, and free from harsh odors, making it the ideal choice for creating a calming, restorative environment without compromising your health. 

Every detail is designed with longevity and safety in mind, no VOCs, no shortcuts, and no unnecessary chemicals, just clean, balanced infrared heat that feels as good as it is for you. 

That’s why our saunas not only look beautiful but also provide a healthier, safer way to enjoy daily detox, recovery, or deep relaxation. 

After 35+ years of crafting the world’s cleanest saunas, we remain committed to offering the purest experience possible, because your health deserves nothing less.

When a sauna heats up, the combination of high temperature and humidity can make plywood and glue-based materials release harmful chemicals into the air. 

Research by Y. Yang et al. (2016) found that plywood emits far higher levels of formaldehyde under heat and moisture, a temperature rise of just 5°C can nearly double emissions. 

This occurs because both the wood fibers and the adhesives used in engineered panels break down, releasing volatile organic compounds (VOCs) such as formaldehyde, phenol, and benzene.

These emissions are more than unpleasant odors, they’re toxic. Inhaling VOCs in a small, heated space can cause headaches, nausea, skin and throat irritation, aggravate asthma, and over time, even raise cancer risks. 

As highlighted in studies like Yang’s, these dangers make it clear why trusted sauna makers avoid plywood, particle board, or synthetic finishes. 

Instead, they rely on solid, untreated woods such as Canadian Hemlock or European Poplar. After all, a true sauna should foster detoxification and relaxation, not surround you with invisible toxins.

When people start exploring infrared saunas, one of the biggest concerns is exposure to EMFs (electromagnetic fields) and ELFs (extremely low frequencies). What many don’t realize is that everyday appliances often give off far higher levels. 

For example, a toaster can measure between 3–70 mg, a hair dryer 60–200 mg, and a blender anywhere from 200–1,200 mg.

Experts at Vitatech Electromagnetics an authority with over 25 years in the field, classify “ultra-low” exposure as 10 mg or below. 

By comparison, independently tested low-EMF saunas such as Sun lighten consistently measure under 1 mg, with some readings as low as 0.1 mg. 

These results come from controlled laboratory testing with advanced instruments. However, it’s worth noting that not all companies measure both magnetic and electric fields, which can give a partial picture.

Safety standards from organizations including the Occupational Safety and Health Administration (OSHA) and the International Commission on Non-Ionizing Radiation Protection (ICNIRP) help guide safe limits. 

Choosing a sauna designed to meet or exceed these benchmarks provides reassurance and supports a healthier wellness journey.

When you’re investing in a sauna, it’s not just about heat, it’s about what you’re breathing in and how your body responds every single session. 

That’s why Heavenly Heat saunas are built differently: no plywood, no glues, no hidden chemicals. 

Many mass-produced saunas rely on adhesives and cheap wood composites that release toxins when heated, but we refuse to cut those corners. 

Instead, we handcraft every model with FSC-certified Canadian Hemlock and glue-free construction, ensuring nothing compromises your health while you relax, recover, or recharge. 

The result is pure, balanced heat that feels clean, restorative, and safe enough to use daily whether you’re detoxing, improving circulation, or simply finding a moment of calm. 

Add in ultra-low EMF technology, third-party VOC testing, and decades of refinement, and you’ll see why health seekers, athletes, and wellness enthusiasts trust Heavenly Heat as the gold standard. Because a sauna should never add toxins to your body, it should help release them, naturally.
