Scientific Reports on Biological Effects of Far Infrared
and Benefits to Your Wellbeing

As we navigate through our middle years and beyond, prioritizing our health and vitality becomes paramount. While well-established practices like a balanced diet and regular exercise remain crucial, scientific research is increasingly highlighting the therapeutic potential of Far Infrared Radiation (FIR) therapy. This gentle and non-invasive approach utilizes a specific range of light energy to support various bodily functions. This article explores the growing scientific evidence for FIR’s positive impacts on blood circulation, inflammation, cellular function, and other biological benefits. FirmClear is the first product that is specifically designed with patented FIR technology to offer these biological benefits and better hearing wellness.

Understanding Far Infrared Radiation

Far infrared (FIR) radiation resides within the infrared portion of the electromagnetic spectrum, characterized by longer wavelengths ranging from 3 to 1000 µm [5] . Unlike ultraviolet or visible light, FIR is not visible to the naked eye but is perceived by the body as a gentle, radiant heat that can penetrate the skin and underlying tissues to a depth of up to 1.5 inches (almost 4 cm) [1, 5]. This deep penetration allows FIR to interact with various biological processes within the body. Two key characteristics of FIR are its ability to induce resonance in water molecules and potentially reduce the size of water molecule clusters, both of which contribute significantly to its beneficial effects [2, 3, 5, 13].

  • Water Molecule Resonance: A fundamental aspect of FIR’s interaction with the body lies in its ability to resonate with water molecules [5]. Water constitutes a significant portion of our tissues and cells [1, 2]. FIR falls within a frequency range that overlaps with the vibrational frequencies of water molecules [3]. When FIR energy is absorbed by water molecules, it increases their molecular vibrations, such as stretching and bending [2]. This resonance effect essentially energizes the water molecules within our bodies [9].
    • The wavelength of FIR emitted from certain materials has been shown to match the absorption wavelength related to the bending motions of cellular water molecules and the OH-stretching movements in water molecules [3].
    • This resonance can amplify the effects of FIR within human tissues because FIR is in the same frequency range as the natural frequency of water molecules [3].
    • The increased vibrational energy in water molecules is thought to contribute to various biological responses, including increased temperature at a cellular level and enhanced molecular interactions [2, 3].
  • Reduction in Water Molecule Cluster Size: Emerging evidence suggests that FIR exposure may also lead to a reduction in the size of water molecule clusters within the body [3, 13]. Water molecules in liquid form tend to associate with each other, forming clusters. 
    • It is hypothesized that FIR energy can increase the motility of body fluids by decreasing the size of these water clusters [13]. The increased kinetic energy from FIR absorption may cause water molecules to move more freely and break away from larger clusters [9].
    • A reduction in water cluster size could lead to improved fluidity of bodily fluids like blood and lymph [9]. This enhanced fluidity can contribute to better microcirculation and more efficient transport of oxygen and nutrients to cells and removal of waste products [9].
    • Furthermore, smaller water clusters may be more effective in participating in cellular processes and interactions with biomolecules [2].

Boosting Blood Circulation for Enhanced Health

Improved blood circulation is one of the most well-researched benefits of FIR therapy [1, 2, 5, 6. 9]. The improved blood flow due to FIR might be partly attributed to the enhanced fluidity of blood resulting from potential reductions in water cluster size and the increased energy of water molecules through resonance, which can affect blood viscosity [9]. This enhanced flow plays a vital role in delivering oxygen and nutrients to cells and removing waste products, contributing to overall health and vitality. There are several mechanisms through which FIR achieves this:

  • Vasodilation: FIR’s thermal energy promotes vasodilation, the widening of blood vessels [1, 2, 5]. This increased diameter allows for greater blood flow, reaching tissues more effectively [6]. Studies have shown that even non-heating FIR can increase skin blood flow in rats [1, 6].
  • Nitric Oxide (NO) Production: FIR exposure has been shown to induce the phosphorylation of endothelial nitric oxide synthase (eNOS) and increase nitric oxide (NO) generation [1, 2]. NO is a crucial molecule that helps relax blood vessels, regulate blood pressure, and prevent blood clot formation [2, 5]. Bioceramics emitting FIR have been shown to increase NO production [5] . (The FIR emitter component in FirmClear contains bioceramics material.)
  • Improved Microcirculation: FIR can improve blood microcirculation [2, 5, 6]. This is particularly important for delivering oxygen and nutrients to smaller blood vessels and tissues. Studies using FIR functional glasses have shown improvements in blood microcirculation [5].
  • Clinical Evidence: Research demonstrates the therapeutic effects of FIR on the cardiovascular system. FIR saunas have been used extensively, particularly in Japan as “Waon therapy,” to improve cardiac and vascular function in patients with chronic heart failure and peripheral arterial disease [1]. FIR therapy has also shown promise in improving blood flow in individuals experiencing discomfort due to cold hands and feet or other blood-flow disorders [3].

Combating Inflammation for Wellbeing

Chronic inflammation is implicated in numerous age-related health issues. Scientific evidence suggests that FIR possesses significant anti-inflammatory properties [2, 5, 6]:

  • Non-Thermal Effects: Notably, FIR can exert anti-inflammatory effects even at low, non-thermal irradiance levels [1, 2]. This suggests that the benefits extend beyond simple heating of tissues.
  • Modulation of Inflammatory Markers: Studies have reported that FIR exposure can inhibit the production of pro-inflammatory cytokines such as IL-6 and TNF-α. It can also attenuate the expression of adhesion molecules involved in the inflammatory process [5].
  • Clinical Applications: Research indicates that FIR therapy can be beneficial in managing conditions characterized by inflammation. For instance, FIR saunas have shown to reduce pain, stiffness, and fatigue in patients with rheumatoid arthritis and ankylosing spondylitis [1]. FIR is also being explored for its potential in treating other inflammatory conditions [2].

Enhancing Cellular Function for Vitality

The resonance of water molecules within cells could directly influence cellular metabolism and the function of proteins and other biomolecules that are surrounded by water [1, 2]. The altered state of water at the cellular level due to FIR absorption might play a role in the observed improvements in mitochondrial activity and other cellular processes essential for maintaining health and vitality [2, 7, 8].:

  • Mitochondrial Activity: FIR irradiation can improve metabolic levels and stimulate mitochondrial respiration [2, 4]. Studies have shown that near-infrared radiation (a related part of the infrared spectrum) can significantly increase cytochrome c oxidase (CCO) activity, a crucial enzyme in the mitochondrial respiratory chain responsible for energy production [4].
  • ATP Synthesis: By enhancing mitochondrial function, FIR can contribute to increased production of adenosine triphosphate (ATP), the primary energy currency of cells. Improved ATP levels can support overall cellular function and resilience.
  • Antioxidant Potentials: FIR may also contribute to antioxidant defense mechanisms [5, 8]. Exposure to FIR has been shown to modulate pathways involving Nrf-2 and glutathione peroxidase-1, key players in protecting cells from oxidative stress [5, 7].

Other Notable Biological Benefits Relevant to Aging

Beyond its impact on circulation, inflammation, and cellular function, FIR has been associated with a range of other potential health benefits particularly relevant as we age:

  • Pain Relief: FIR therapy is known for its ability to provide relief from muscle and joint pain [1, 2, 6].
  • Muscle Recovery: FIR can aid in faster muscle recovery after physical activity by reducing muscle soreness [1, 2].
  • Sleep Improvement: Some studies suggest that FIR therapy can contribute to improved sleep quality [5, 9, 10].
  • Skin Health: FIR has been explored for its potential in promoting skin wound healing and improving overall skin complexion [1, 2, 4, 5, 8, 9].
  • Neuroprotection: Research indicates that FIR may have protective effects on the nervous system, potentially attenuating stress, memory impairments, and promoting nerve regeneration [2, 5, 8]. FIR has also shown potential in promoting neurite outgrowth, crucial for nerve repair [2, 8].
  • Hearing Research Connection: While current research on direct connection between FIR and hearing is limited, the concept of neural stimulation by infrared light has been reported [4, 12]. Furthermore, photobiomodulation (PBM), which includes infrared light, is being explored in hearing research for hair cell protection and hearing threshold recovery in animal models after noise exposure [11].

Benefits of FIR to Adults and Aging Population

For adults, especially aging population, the benefits of FIR therapy can be particularly significant:

  • Maintaining Cardiovascular Health: Improved blood circulation supports healthy heart function as we age.
  • Addressing Age-Related Inflammation: Reducing chronic inflammation can have broad positive effects on overall wellbeing.
  • Supporting Energy Levels: Enhanced cellular function and ATP production can help combat age-related fatigue.
  • Alleviating Joint and Muscle Discomfort: FIR offers a non-pharmacological approach to managing common aches and pains.
  • Promoting Recovery: For active individuals, FIR can aid in faster recovery from exercise.

Conclusion

The scientific evidence strongly suggests that Far Infrared Radiation offers a multitude of health benefits, particularly in improving blood circulation, reducing inflammation, and enhancing cellular function. For individuals in their middle years and beyond who are keen on proactively supporting their wellbeing, FIR therapy presents a promising and safe option. While research continues to deepen our understanding of its full potential, the existing findings offer a compelling case for considering the integration of FIR into a healthy lifestyle. As always, it is advisable to consult with a healthcare professional to determine if FIR therapy is appropriate for your individual health needs.
