What illnesses and diseases does infrared therapy treat?


A study on toenail fungal infections found that a specialized dual-wavelength infrared laser can treat and cure onychomycosis.

It operates at safe temperatures for human tissue, using 870- and 930-nm wavelengths to effectively target and kill fungal pathogens without the risks of ultraviolet light or toxic byproducts from other lasers.

Results indicated significant improvement in 85% of treated nails by day 180, with clear nail growth of 3 mm or more in 65% of cases and at least 4 mm in 26%. In moderate to severe cases, 63% showed cleared fungal growth and 30% showed negative culture results at 180 days.


Recent research over the last ten years indicates that infrared radiation (IR) can cause DNA damage in cancer cells. This is thought to occur through a process linked to oxidative stress.

IR radiation impacts the electron transport chain, leading to the production of reactive oxygen species (ROS). While ROS can activate signal transduction pathways at moderate concentrations, high levels can directly harm cellular structures


Infrared light therapy has been shown to improve blood circulation by dilating blood vessels and increasing blood flow to the treated area. This increased circulation delivers oxygen and nutrients to the tissues, while also removing waste products and toxins. Improved blood circulation helps accelerate the healing process and reduces inflammation.


infrared light therapy has been found to aid in weight loss and body detoxification. By increasing metabolism and promoting the breakdown of fat cells, this therapy can support weight management efforts. Additionally, the deep heat generated by infrared light can stimulate sweat production, facilitating the elimination of toxins from the body.


Another notable benefit of infrared light therapy is its potential for boosting the immune system. The increased circulation and activation of cellular energy production stimulated by this therapy can strengthen the body’s defense mechanisms, making it more resistant to infections and illnesses.


infrared light therapy has been shown to support the regulation of serotonin levels in the brain. Serotonin is a crucial neurotransmitter that plays a crucial role in mood regulation and emotional stability. By promoting the balance of serotonin, infrared light therapy can have a positive impact on conditions such as seasonal affective disorder (SAD) and other forms of depression.

It offers a soothing and calming effect on the nervous system. It can help reduce the symptoms of insomnia and improve sleep quality, allowing individuals to wake up feeling refreshed and rejuvenated. Quality sleep is essential for emotional wellbeing, as it helps regulate emotions and reduces the risk of developing mental health disorders.


By stimulating the release of endorphins, the body’s natural painkillers, infrared light therapy can help alleviate chronic pain conditions such as arthritis, fibromyalgia, and muscle soreness. It also aids in reducing muscle tension and promoting relaxation, making it an excellent option for stress relief and overall well-being.

Infrared light has been found to stimulate the production of endorphins, natural pain-relieving chemicals in the body. This opens up new possibilities for the treatment of chronic pain conditions such as arthritis, fibromyalgia, and back pain.

With further research and technological advancements, we can expect more targeted and effective infrared light therapy devices to emerge, offering relief to those suffering from debilitating pain.


Research has also shown that infrared light therapy can have positive effects on skin health. It can stimulate collagen production, improve skin elasticity, and reduce the appearance of wrinkles and fine lines. This makes it a popular choice for skincare treatments and anti-aging regimens.

One of the most appealing aspects of infrared light therapy is its non-invasive nature. Unlike UV light therapy, which can cause sunburn and skin damage if not used properly, infrared light therapy is safe and gentle on the skin. It does not emit harmful UV rays and does not carry the same risks of premature agingsuggest cancer associated with excessive sun exposure.


Studies suggests that the therapy can improve focus, attention, and memory. Researchers have found that transcranial brain stimulation with IR radiation can rehabilitate neurodegenerative brain diseases or traumatic brain injury, and modulate a neurobiological function.

By increasing blood flow and oxygenation to the brain, infrared light stimulates neuronal activity, leading to enhanced cognitive performance. This can be especially beneficial for individuals experiencing brain fog or cognitive decline.

Brain disorders that can be treated include: TBI, Alzheimer’s disease, Parkinson’s disease, and stroke.


this therapy has been found to have positive effects on cardiovascular health. By promoting vasodilation and improving circulation, infrared light therapy can help lower blood pressure, enhance cardiovascular function, and even reduce the risk of cardiovascular diseases.

The Science

Infrared light therapy activates various cellular signaling pathways, including the release of nitric oxide (NO) and the stimulation of reactive oxygen species (ROS). These signaling molecules play important roles in cellular communication, immune response, and tissue repair.

Another great effect of infrared light therapy is an increase in cellular energy production.

The mitochondria, often referred to as the powerhouse of the cell, are responsible for producing energy in the form of adenosine triphosphate (ATP). The absorption of infrared light by the mitochondria triggers a cascade of beneficial effects.

The impact of infrared radiation on water within membranes, mitochondria, and cells can affect key cellular processes, including signaling pathways, and the synthesis of reactive oxygen species (ROS), adenosine triphosphate (ATP), Ca2+ ions, nitric oxide (NO), and inositol phosphates.

This boost in energy (sound waves) via these key cellular processes enhances cellular function and metabolism, leading to improved healing, tissue repair, and overall wellness.

These secondary effects stem from initial changes such as stress response signaling, alterations in metabolism, organization of the cytoskeleton, as well as processes involving cell growth and differentiation, and maintaining equilibrium, especially in response to injury or shifts in metabolic redox potentials.

Additionally, infrared light therapy has been shown to increase the production of nitric oxide, a molecule that plays a crucial role in promoting blood flow and reducing inflammation.

Intracellular calcium (Ca2+) serves as a crucial secondary messenger in various biological activities, including the contraction of smooth muscles, the release of neurotransmitters, and the modulation of signaling pathways.

When neonatal rat ventricular cardiomyocytes were exposed to 1862 nm infrared (IR) radiation, there was a noticeable increase in intracellular calcium, similar to that which causes pulsing frequencies in these cells.

Humans are constantly exposed to environmental IR radiation, which may either indirectly or directly trigger the generation of free radicals or reactive oxygen species (ROS). Some studies have suggested that a short surge in ROS induced by IR could aid in photorejuvenation.

Furthermore, the application of IR radiation (8~12 μm) in rat skin wound healing has demonstrated an enhanced release of growth factors and anti-inflammatory cytokines like transforming growth factor-β1 (TGF-β1), facilitating fibroblast activation and thus promoting wound healing.

Electron paramagnetic resonance spectroscopy, which detects microwave radiation absorption by unpaired electrons in a magnetic field, can measure spin reversals and microwave energy absorption.

The influence of microwave radiation on rotational water movement in tissues, particularly its significant damping effect, should be accounted for to prevent high impedance at 109Hz frequencies.
