Key Takeaways
- Wavelength Matters: Near Infrared (NIR) uses shorter wavelengths (700nm–1400nm) for skin and cellular health, while Far Infrared (FIR) uses longer wavelengths (3000nm–1mm) for deep heat and detox.
- Primary Benefit: Choose FIR for relaxation and heavy sweating; choose NIR for skin rejuvenation and pain management.
- Safety Check: Always look for Low EMF or Ultra Low EMF ratings, especially when building or buying a unit.
- Full Spectrum: If you can’t decide, full spectrum infrared saunas offer the best of both worlds by combining NIR, Mid, and FIR wavelengths.
Understanding the Spectrum: What is the Difference?
To understand the debate, we first have to take a look at the physics. Infrared light comes under the electromagnetic spectrum. It is not visible to human eyes, but is felt as heat.
Near vs Far Infrared Wavelength: The Science
The basic difference is in the near vs far infrared wavelength.
- Near Infrared (NIR): These wavelengths range from about 700 nanometer to 1400 nanometer. They are closest to the visible light on the spectrum. Because they are shorter, they do not heat up the air around you as much-as much-and rather they penetrate deeply into the tissues of the body.
- Far Infrared (FIR): These wavelengths are between 3,000 nanometers and 1 millimeter. They are “far” from the visible light. These longer wavelengths oscillate at a frequency that interacts strongly with the water molecules in your body to produce an intense heating effect that triggers a heavy sweat.
What is a Near Infrared Sauna?
When people ask, “what is a near infrared sauna“, what they are often asking about is a specific type of heat therapy that often uses incandescent bulbs or specialized LED panels.
Unlike traditional saunas that heat the air, a NIR sauna is focused on light therapy. The heat is direct – you feel it closest where the light strikes your skin. This is why NIR saunas are frequently smaller, occasionally only being a reflecting dome or comprising a set of red lights.
Near Infrared Sauna Benefits
The benefits of NIR are unique from FIR due to the interaction of the light with your cells.
- Cellular Regeneration: NIR light activates the mitochondria in your cells (powerhouse of the cell) to create more ATP (Adenosine Triphosphate energy): This is why near and far infrared light therapy is often used when trying to recover.
- Skin Health: NIR is widely used in dermatology. It can help to increase collagen production, minimize wrinkles, and treat acne or scarring.
- Wound Healing: Since it stimulates the energy of cells, it accelerates wound healing.
Near Infrared Sauna Dangers: What You Need To Know
While relatively safe, there are some specific considerations of the dangers of using near infrared saunas. Since the NIR is commonly done using bright incandescent bulbs, eye protection is important.
Staring directly at high intensity NIR bulbs can destroy the retina. Additionally, because the heat is concentrated it is easier to accidentally burn yourself should you get too close to the source.
What is a Far Infrared Sauna?
If you step into a wooden cabin at a spa you are likely to be using a Far Infrared sauna. What is a far infrared sauna? It is an enclosed cabin with ceramic (or carbon) heaters that emit FIR waves.
What does far infrared sauna mean for the user experience? It means a “wet heat” sensation, though you may not be pouring water on rocks.
The FIR waves resonate with the water in your body and make you sweat a lot at lower temperatures (typically between 120 degrees F and 140 degrees F) compared to traditional steam saunas.
How Does a Far Infrared Sauna Work?
How does a far infrared sauna actually work? The heaters release radiant heat and this is absorbed by the body’s surface. Instead of heating the air to suffocating temperatures the energy is transferred directly to the body.
This process is known as what is far infrared sauna therapy and increases your internal body temperature, setting up an artificial fever state, which improves the immune system and ramps up cardiovascular circulation.
What are the Benefits of Far Infrared Sauna?
When researching what are the benefits of far infrared sauna, three main pillars stand out:
- Detoxification: The deep sweat is widely believed to help remove heavy metals and toxins such as mercury and lead, though there is still a developing scientific consensus on the extent of the heavy metal detox by the sweat of the body.
- Cardiovascular Health: This maintenance and frequent use can lower blood pressure and get the heart rate in a better condition, serving as a slight cardio exercise.
- Relaxation: The heat promotes the release of cortisol hormones that helps to alleviate stress and promote a better sleep.
Near vs Far Infrared Sauna Benefits: Head to Head
If you are seeking near vs far infrared sauna benefits to make a decision of use, look at your primary objectives for your health.
Near vs Far Infrared Sauna Benefits
| Feature | Near Infrared (NIR) | Far Infrared (FIR) |
|---|---|---|
| Primary Goal | Skin health, cellular energy, pain relief | Detox, weight loss, relaxation |
| Sweat Level | Moderate | Heavy/Profuse |
| Penetration | Deepest tissue penetration | Surface & mid-level tissue penetration |
| Heating Method | Light bulbs or LEDs (Direct) | Carbon/Ceramic heaters (Ambient) |
| Experience | Bright light, focused heat | Dim, warm cabin environment |
Near Infrared vs Far Infrared For Cancer
This is an issue that is sensitive and heavily researched. When looking for the near infrared vs far infrared for cancer, it is important to distinguish fact from fiction.
Current research indicates that hyperthermia (raising the body temperature) can be a supportive therapy to cancer treatment since often cancer cells are more sensitive to the heat than normal cells. FIR saunas are great for delivering whole body hyperthermia.
Conversely, NIR is being researched for Photobiomodulation (PBM) which uses light to create stimulation of cellular function. Some research indicates that PBM may assist in the management of side effects of chemotherapy.
However, neither sauna can be considered as a solution for cancer alone. Always seek the advice of an oncologist before use.
EMF Safety: What Is Low EMF and Ultra Low EMF
One of the largest concerns that buyers have is Electromagnetic Fields (EMF). When you are asking what is emf far infrared sauna, you are probably concerned with the invisible radiation emitted by electrical devices.
- What is low Emf far infrared Sauna? This normally means that the sauna has been tested to make sure the EMF levels are below 10 milligauss (mG) at the point of contact.
- What is Ultra low emf far infrared sauna? These units are also designed to produce even less, typically less than 3-5 mG and are virtually non-detectable.
NIR saunas using LED panels generally have negligible Emf. However, older NIR lamps or poorly wired FIR saunas may give off large levels. When purchasing it is always good to check the third party of the brand to see their EMF testing.
How To Build Your Own Near infrared Sauna
Many DIY enthusiasts search the internet for the question of how to build near infrared sauna plans as NIR saunas are mechanically simpler. You do not need a wooden cabin, you just need a space for the lamps.
Steps:
- Buy 4-6 250Watt red incandescent heat bulbs.
- Construct a reflective shield or place them on a board.
- Be sure to make the wiring safe (consult an electrician if you are not sure).
- Set-up a chair and move your body in the session.
If you are looking for a near infrared sauna onhow to make near infrared sauna setups safe, make sure to use GFCI (Ground Fault Circuit Interrupter) Outlets so that you avoid a shock.
How to Use a Far Infrared Sauna
Knowing how to use a far infrared sauna is very important in getting the most benefits.
