Low level laser therapy (LLLT), also known as photobiomodulation, is a technique which uses a low-level laser or light emitting diodes (LED) to improve and repair tissue, reduce pain and lower inflammation. TrueLight™ is the only photobiomodulation device on the market that provides four different wavelengths of light, as well as settings to choose between pulsating and constant light, for faster healing, pain relief and recovery.
Near-infrared (NIR) light therapy is similar to red light therapy, except infrared energy is invisible, and it penetrates the body deeper than red — reaching deep into soft tissues, muscles, joints, and bone.
NIR wavelengths (typically 850nm or 880nm) have been reported as penetrating deeper than other light wavelengths through skin and bone. Skin depth varies around the body, and transmission can also be affected by skin pigmentation levels.
NIR light has been used in light therapeutic devices to assist in addressing a variety of injuries. It penetrates more deeply than UV or visible light and is benign to living tissue. There is very little heat generated by the LED array and therefore no potential thermal injury to individuals being treated. LED is well-tolerated by biological tissues and has no known detrimental effect. As a therapeutic device, LED has achieved an FDA low-risk general wellness status.
The science behind light therapy
Researchers working with NASA have found that light therapy using NIR LEDs operate by activating color-sensitive chemicals in body tissues, stimulating the process in a cell’s mitochondria. Light wavelengths from 680nm to 880nm have been found to travel through skin and muscle tissue, to prompt tissue and deep wound healing. Light penetration depends on power, wavelength and proximity to skin.
The basic premise is that long wavelength lights stimulate cellular energy metabolism and energy production. Three major photoacceptor molecules in mammalian tissues are known to absorb light in the NIR range: hemoglobin, myoglobin, and cytochrome c oxidase. Of the three, cytochrome c oxidase has been associated with energy production.
Pulsed Light vs. Constant Light
It has been discovered that when specific frequencies of LED lights are pulsed, body tissue can heal more rapidly. When it is given a continuous burst, it sedates the cell and relieves the pain. When a single-frequency pulsed light hits the cell, it stimulates the cell to start producing more protein than it normally does, as a result, the cell heals faster. Even when the LED light source is taken away, the cell continues its healing. Alternatively, using a continuous light/beam has an effect that can remove/dull pain, reduce inﬂammation and allows muscle tissue to relax.
New routine at the gym making you sore? Muscles exhausted from to much yard work or just looking to add a variation into your daily meditation? Here are some great ideas to incorporate light therapy into your daily life!
If you’re interested in at home light therapy, consider TrueLight ™. It is the only photobiomodulation device on the market that provides four different wavelengths of light, including NIR, as well as both pulsating and constant light. This patent-pending solution offers the maximum feature set for faster healing, pain relief, and recovery.
Junk light exposure when traveling can disrupt your circadian rhythm. Long-term exposure to light at night which accompanies shift work is listed as a probable carcinogen by the World Health Organization. Light at night has shown to be highly associated with significantly the risk of hormone specific such as cancers of the breast and prostate.
The flickering wavelength of light associated with LEDs and compact fluorescent lights emit blue light that inhibits melatonin production but also create a unique glare that impacts your retina causing eye strain, headaches, and physical and mental fatigue.
Red light and darkness move leptin and ghrelin into patterns that are (context dependent) associated with less hunger, while blue light does the opposite and can move both into patterns associated with more hunger.
Increase in cortisol, the stress hormone, due to circadian disruption. Memory recall is impaired with consistent sleep deprivation and may leave you distracted and not performing your absolute best.
The Importance of Melanopsin Cells
Your body requires some blue light at the right time of day and from the right sources. That’s why we created TrueDark® Sleep Technology that gives you 24-protection from junk light day and night.
Stop Junk Light with patented TrueDark® Twilight technology that frees your hormones and neurotransmitters to do their best work.
When the sun goes down, blue light isn’t the only junk light that can disrupt our sleep cycle and more than blue blockers are needed. Patented TrueDark® Twilight is the first and only solution that is designed to work with melanopsin, a protein in your eyes responsible for absorbing light and sending sleep/wake signals to your brain. Without melanopsin, melatonin can’t be accessed.
When you wear your Twilights for as little as 30 min before bed you prevent your melanopsin from detecting the wrong wavelengths of light at the wrong time of day. This supports your circadian rhythm and helps you fall asleep faster and get more restorative and restful sleep.
The highly advanced lenses in TrueDark® Daywalkers operate on a more advanced level than traditional blue blockers.
Blue light emitted from the sun helps regulate our sleep/wake cycle. However, in today’s world, we’re exposed to an overabundance of blue light, or junk light from artificial light. This includes hours spent in front of TVs, phones, and computers. It also includes time spent in artificial man made light with LEDs and fluorescent lights. Even if we’re simply reading a book, we’re doing that in artificial light which emit dramatically more blue light than the sun. That overexposure to junk light during the day has a dramatic impact on our neurotransmitters and hormones that are responsible for quality sleep.
