Love Health Benefits Plus

Hybrid Sauna Health Benefits

Hybrid saunas combine the best of traditional and infrared saunas, offering a unique combination of heat therapies that provide a wide range of scientifically supported health benefits.

  • Detoxification: The dual heat system increases sweat production, helping eliminate toxins like heavy metals and chemicals. Infrared heat penetrates deeper, enhancing detoxification by up to 20% more compared to traditional heat alone.
  • Improved Cardiovascular Health: Regular use of hybrid saunas has been shown to lower blood pressure, improve circulation, and reduce the risk of heart disease. The combination of traditional and infrared heat offers a balanced approach for heart health.
  • Pain Relief & Muscle Recovery: The infrared component helps reduce inflammation and accelerates muscle recovery, while the traditional heat provides immediate relaxation and relief. Clinical studies show that 70% of chronic pain sufferers experience relief with consistent use of infrared heat.
  • Skin Health & Anti-Aging: Hybrid saunas stimulate collagen production and improve skin elasticity, with infrared heat enhancing hydration and reducing wrinkles by up to 26%. Traditional heat opens pores and removes impurities for clearer, healthier skin.
  • Stress Relief & Better Sleep: The combination of traditional heat for immediate relaxation and infrared heat for deeper stress relief helps reduce cortisol levels, leading to improved sleep and mental clarity. 83% of users report better sleep after regular sessions.

These benefits make hybrid saunas a powerful and versatile tool for overall wellness, allowing you to enjoy the advantages of both traditional and infrared therapy in one system.

What About EMF? Plus

Understanding EMF in Infrared and Hybrid Saunas

What is EMF?

Electromagnetic fields (EMF) are invisible areas of energy, often associated with electrical power and devices like phones, computers, and household appliances. EMFs are categorized into two types: low-frequency and high-frequency. While high-frequency EMFs (such as x-rays) can be harmful with prolonged exposure, low-frequency EMFs (like those emitted from saunas and most electronics) are generally considered safe when kept within established guidelines.

Why Are EMFs Relevant for Saunas?

Because infrared and hybrid saunas use electricity to power infrared heaters and other components, some customers may be concerned about their exposure to EMFs during use. However, the good news is that our saunas are specifically designed to minimize EMF exposure, making them safe for everyday use.

Our Commitment to Safety

We understand that safety is a top priority for our customers, which is why all of our infrared and hybrid saunas are third-party tested and certified to meet or exceed the EPA’s guidelines for safe EMF exposure. The low-frequency EMF levels emitted by our saunas are well within the safe range, especially when compared to many of the electronic devices you’re likely already surrounded by daily, such as smartphones, laptops, and Wi-Fi routers.

EMF Levels in Perspective

To put things into perspective, the EMF levels produced by our saunas are significantly lower than those found in everyday household electronics. For example, the average laptop or smartphone can emit EMF levels several times higher than what you’ll experience during a sauna session in one of our units. Our commitment to low-EMF technology ensures you can enjoy all the health benefits of infrared and hybrid saunas without worry.

A Safe, Rejuvenating Experience

With our rigorously tested, low-EMF saunas, you can confidently enjoy the detoxifying, relaxing, and rejuvenating benefits of infrared heat, knowing that your exposure to EMFs is minimal and well below safety limits. Our saunas are designed not only for your wellness but also for your peace of mind.

How do I decide between an infrared sauna and a traditional sauna? Plus

Choosing between an infrared sauna and a traditional sauna depends on your personal preferences, health goals, space, budget, and other practical considerations like power requirements. Here’s a breakdown to help you decide:

1. Heat Experience & Comfort:

  • Traditional Saunas: Heat the air to high temperatures (up to 190°F) and warm your body from the outside in. This creates an intense, steamy environment that many people love for its authenticity and immediate sweating.
  • Best for: Those who enjoy high heat and steam, and want the classic sauna experience.
  • Infrared Saunas: Use infrared light to directly heat your body at lower temperatures (120-150°F). This gentle heat penetrates deeper into the muscles and tissues, allowing for longer, more comfortable sessions.
  • Best for: People who prefer a milder, more gradual heat and still want deep detoxification.

2. Health Benefits:

  • Traditional Saunas: Great for improving cardiovascular health, muscle relaxation, and detoxification through intense sweat. They are effective at reducing heart disease risk by up to 63% and relieving joint and muscle pain.
  • Infrared Saunas: Offer similar benefits but with deeper penetration, promoting enhanced detoxification (up to 20% more), collagen production for better skin, and more effective pain relief and muscle recovery.

3. Cost:

  • Traditional Saunas: Typically more expensive upfront due to the construction requirements (wood, rock heaters, etc.). They also may incur higher operational costs due to their energy consumption.
  • Best for: Those who are willing to invest more for a luxurious, authentic experience.
  • Infrared Saunas: Usually more affordable, with lower upfront costs and more energy-efficient operation. They use less power, which helps save on electricity bills.
  • Best for: People on a budget looking for an economical option with lower ongoing costs.

4. Power Requirements:

  • Traditional Saunas: Often require dedicated electrical wiring and professional installation due to their higher power needs, especially for larger models.
  • Best for: Those prepared for a more involved setup and higher electrical demands.
  • Infrared Saunas: Use less power and many 1- or 2-person models can be plugged into a standard 120-volt outlet, meaning no electrician is required for most smaller models.
  • Best for: People looking for a simple, plug-and-play setup without the need for special wiring.

5. Space & Installation:

  • Traditional Saunas: Require more space due to their design, especially if you want steam options. They are typically installed in larger areas like basements, home gyms, or outdoor spaces.
  • Best for: Those with ample space and the desire for a more immersive, traditional setup.
  • Infrared Saunas: Tend to be more compact and space-efficient, making them suitable for smaller areas like bathrooms, closets, or even bedrooms.
  • Best for: Those with limited space or seeking a more flexible, portable option.

6. Energy Efficiency:

  • Traditional Saunas: Use more energy because they need to heat the entire room and maintain high temperatures for the session.
  • Best for: Those who don’t mind higher energy use for a more intense sauna experience.
  • Infrared Saunas: More energy-efficient, as they use less power and operate at lower temperatures.
  • Best for: Those looking to reduce energy consumption and environmental impact.

7. Maintenance:

  • Traditional Saunas: Require ongoing maintenance, especially with wood care and the rock heaters, which need cleaning and periodic replacement of stones.
  • Best for: Those who don’t mind the upkeep for a traditional experience.
  • Infrared Saunas: Generally lower maintenance, with fewer components needing care. The infrared panels are durable and require minimal upkeep.
  • Best for: Those looking for a low-maintenance option.

Key Considerations:

  • If you prefer high heat and the classic sauna experience, and you have the space and budget for it, a traditional sauna might be the best choice.
  • If you’re looking for a more affordable, energy-efficient, and space-friendly option with deep health benefits (like enhanced detoxification and easy installation), an infrared sauna may be more suitable.

Summary:

  • Choose a traditional sauna if you want an intense, authentic sauna experience and don’t mind higher upfront costs, energy use, or more involved installation.
  • Choose an infrared sauna if you prefer a gentler heat, want to save on energy and installation costs, and value a compact, low-maintenance setup.

Can you assemble my sauna for me? Plus

This sauna is built to assemble easily within 30 minutes to two hours with two adults with no tools necessary. If, for whatever reason, you are unable to do it yourself, we recommend hiring a local handyman to do it for you.

Do you provide financing? Plus

We have partnered with Shop Pay to offer financing options at checkout. Just select Shop Pay Installments as your payment method in Step 3 at checkout and follow their instructions.

How hot do your saunas get? Plus

Our traditional saunas typically get up to 195F with a basic heater and can get up to 230F with a premium heater. Most of our infrared saunas get up to 140F, but if you want an infrared sauna that gets up to 170F, check out our Finnmark line.

Can I put an indoor sauna outside? Plus

Yes, as long as it's not exposed to sun and rain directly. If you don't plan to put it under a covered patio or something similar, we recommend getting a custom outdoor sauna cover for it and keeping it covered as shown.

What is the difference between a regular model and the Elite version? (Low EMF vs Ultra Low EMF) Plus

Just the heating panels. Otherwise they're identical. The regular low EMF model emits less than 8mG and the Elite version emits less than 3mG. If you’re not familiar, EMF stands for electromagnetic frequency and you can think of it kind of like radiation. Long story short, the less EMF you expose yourself to, the healthier you’ll be, so it’s always best to go with the Elite version if you plan to make a habit out of using your sauna, and you can afford the upgrade.

What is chromotherapy and what does it do? Plus

Chromotherapy, also known as color therapy, is a form of alternative therapy that uses colors to improve physical and mental well-being. The idea behind chromotherapy is that different colors have specific wavelengths and energy frequencies, which can influence a person’s mood, emotions, and even health when absorbed by the body. Each color is believed to have unique healing properties.

  • Red: Stimulates energy, vitality, and circulation.
  • Orange: Promotes creativity, enthusiasm, and emotional balance.
  • Yellow: Boosts mood, self-confidence, and concentration.
  • Green: Known for its calming and balancing effects, aiding in relaxation and stress relief.
  • Blue: Soothes anxiety, promotes calm, and helps with sleep disorders.
  • Indigo: Encourages deeper levels of relaxation and introspection.
  • Violet: Supports mental clarity and spiritual awareness.
What is red light therapy and what is it good for? Plus

Red light therapy uses low wavelengths of red or near-infrared light to penetrate the skin and stimulate cellular repair, boost collagen production, and reduce inflammation. It’s commonly used for improving skin health (anti-aging, wrinkles), speeding up muscle recovery, relieving pain, and enhancing circulation. It’s also beneficial for wound healing, hair growth, and even improving sleep and mood by supporting cellular energy production and reducing stress on the body.
