The Best Infrared Light Therapy

Proven pain relieving infrared light therapy devices from HealthLight. Our At-Home LED Light Therapy Line is available for home and professional use.

What Is Infrared Light Therapy?

Infrared light therapy is a procedure that uses light-emitting diodes (LEDs) to relieve pain caused by acute or chronic injury. By low intensity light in the red or near infrared (NIR) spectrum (600nm – 1000nm) to stimulate healing. Infrared light therapy is non-invasive, painless, and does not use heat.

Light has a photochemical effect comparable to photosynthesis in plants. For light therapy to work, enough light has to penetrate below the surface of the skin and be absorbed by cells to exert a sufficient chemical change.

The Science Behind Infrared Light Therapy

Infrared light therapy is backed by years of science. In 1993, Duke University researchers discovered the benefits of infrared light therapy. In 1998, three American physiologists won the Nobel Prize for discovering that nitric oxide causes the blood vessels to dilate. This effect can be seen when a patient with angina takes nitroglycerin. The blood vessels dilate and reduce the angina. However, nitric oxide must be taken by mouth and reach the heart systemically via the blood flow.

Therapeutic infrared light often come in the form of LEDs, as they are a safe and cost efficient method to deliver light therapy to specific areas of the body. Unlike medical lasers, HealthLight red light therapy pads do not require use of protective eyewear during treatment.

Infrared light therapy involves illuminating concentrated wavelengths of light between 810nm and 850nm on bare skin. The treatment is based on light photons interacting with light-sensitive molecules in each cell.

When infrared light photons reach these molecules, they can stimulate mitochondrial cells (commonly called “cell energy generators”) to produce more adenosine triphosphate (ATP), which stimulates cellular energy production.

This in turn supplies energy to all the cells that are illuminated by the light. Self-protective factors such as antioxidants are released to prevent inflammatory cell damage. And cells can perform their functions more efficiently, including repairs and remodelling. This enhanced feature has anti-aging benefits as well as the ability to treat the causes of many diseases and ailments.

Mitochondria actually produce more than just cellular energy. It also controls cell life, including natural cell death. When cells are diseased or damaged, mitochondria send signals that instruct the cell to self-destruct. However, when mitochondrial dysfunction causes unintentional cell death, it triggers the production of free radicals, which damage neighboring cells. Infrared light therapy helps improve mitochondrial function and also activates antioxidant molecules that fight free radicals. This means that infrared light therapy reduces chronic inflammation caused by oxidative stress.

This means that infrared light therapy stimulates the body to reduce chronic inflammation caused by oxidative stress. Chronic inflammation is a major cause or cause of almost all diseases, such as rapid aging.


The Benefit of Infrared Light Therapy For Your Patients

When selecting a light therapy program for your patients, it's important that you take the specifications of the LED pads into consideration. The medical benefits from light therapy is dependent on: wavelength and power.

  • Wavelength (measured in nm) needs to be sufficient in order to achieve an adequate dosage. The bulk of clinical literature suggests that light in the mid-600nm range to high-800nm range is most effective. That is because these wavelengths have the greatest effect on the cellular respiration process.
  • Power Density is the amount of light power delivered to an area of the body. HealthLight infrared light therapy pads are powerful enough to stimulate healing of the body.

Why people can benefit from infrared light therapy

Tricolor infrared Therapy Pad

We see sunlight as much brighter white light. This effect is most noticeable in the afternoon, when the color of the sun is not distorted by the atmosphere. But inside the white light is a rainbow of colors that seem to be white together, as well as colors that are incomprehensible to the human eye.

Humans do not see the full spectrum of electromagnetic energy, which we call “light,” but we can see the wavelengths that are most beneficial to our bodies. The human eye can see light from purple to red light, but higher wavelengths can usually provide more therapeutic benefits.

The shortest wavelength detected by the human eye in the visible light spectrum is about 380 nanometers (nm), which our brain perceives as purple. Wavelengths shorter than 380nm fall into the ultraviolet

(UV) spectrum, which is invisible to humans but has a strong effect on bare skin – as anyone who has been badly burned is well aware. Due to its potential to burn and cause skin damage such as skin cancer, UV light is often considered dangerous. However, it has therapeutic benefits. At the upper end of the spectrum, the eye can observe red wavelengths that range between 600nm and 650nm.


The Spectrum of Infrared Light Therapy

Infrared Light Therapy Frequency

The human eye loses sight of light at about 740nm, which is in the long range of the red spectrum. Furthermore, the infrared range of light, which is invisible except under certain conditions. We understand these higher electromagnetic waves as heat as light.

Why is it important? Every wavelength of visible and invisible light affects the human body. However, we now know that relatively high wavelengths (red and NIR) have the most advantages and the least side effects.

What are the uses for near infrared light therapy?

Red Light Therapy Tissue Penetration

As the following studies have shown, NIR light therapy does not only cure symptoms; cured inflammation, which is the root cause of many conditions.

NIR light therapy can help reverse the signs of skin aging, including fine lines, wrinkles, sunspots, and sagging, paper skin. In the deeper layers of the skin, NIR increases the production of collagen and elastin.

Restores the thickness, firmness and elasticity of youthful skin. Most studies have shown 6 to 12 weeks of consistent therapy for the best skin rejuvenation results.

NIR light therapy balances thyroid function. The thyroid gland is important for overall health because its functions include regulating metabolism through the release of hormones. Thyroid failure can lead to severe fatigue, mental fog, weight gain, hair loss and muscle weakness. NIR light therapy promotes a healthy circadian rhythm (natural sleep / wake cycle). The hypothalamus, which is responsible for the circadian rhythm, is highly photosensitive. NIR light stimulates the production of melatonin, which helps quality sleep.

Due to its high wavelength, NIR light can penetrate the skull as it passes through the forehead. In the brain, NIR light has neuroprotective effects on brain cells. It reduces oxidative stress (which is associated with neurodegenerative disorders such as Alzheimer’s disease) and stimulates normal neurogenesis (the birth of new brain cells), which helps to recover from traumatic brain injury.

NIR light therapy improves the sexual and reproductive health of men. It has been shown to safely increase sperm motility (increase the chance of conception) and stimulate energy production in testosterone-producing Leydig cells.

NIR light therapy promotes wound healing through increased transient inflammation (healthy temporary immune response to injury), increased blood flow, and regulated collagen production, which stimulates the growth of normal tissue instead of scar tissue.

Elite athletes have long used NIR light therapy on key muscles to try and improve muscle healing. It can stimulate the growth of muscle mass, reduce muscle fatigue (during exercise) and alleviate the effects of

delayed onset of muscle pain or pain that occurs two to three days after intense exercise.

NIR light therapy is effective in reducing chronic inflammatory pain, including carpal tunnel syndrome, knee pain due to osteoarthritis, and acute and chronic lower back pain.
NIR light therapy can control bone growth and accelerate bone healing. It also activates stem cells, which are essential for the immune response as well as healthy wound healing.
While some NIR light therapy studies have focused only on symptomatic relief, a reasonable assumption is that deeper penetration of NIR wavelengths – which reduce inflammation in deep body tissues – can affect wrinkle health and therefore accelerate cell health.

What is red light therapy (RLT)?

Red light therapy (RLT) uses red low-level wavelengths of visible light on the skin and body which can result in many different benefits, including temporary relaxation of muscles, temporary relief from muscle spasms, etc.

ir light skin penetration
Science Behind

RLT acts mainly on the mitochondria, where most light absorption in the cell occurs. It influences the amount of energy the mitochondria produce and increases the production of ATP (adenosine triphosphate), the energy-carrying molecule.

Vasodilation blood flow
How It Works

RLT triggers the release of nitric oxide (NO) from blood vessels and red blood cells. NO causes local vasodilation. Vasodilation significantly improves blood flow. Improving blood flow promotes positive change in patients, lessens pain and helps nerves to begin to carry sensations again.

Red light therapy is also known as the following: photobiomodulation (PBM), low-power laser therapy (LPLT), low level light therapy (LLLT).
