Scientific Benefits of Light Therapy

Benefits of Kala Red Light Therapy

Light therapy is not a wellness fad or myth. Researchers have conducted over a thousand peer-reviewed trials and studies on various kinds of light therapy (also referred to as photobiomodulation or low-level laser therapy). It’s a legitimate and widely-used health intervention to improve how you feel, look and preform. In fact, NASA studied light therapy in the late 1980s and 1990s for use in space, and over the last two decades. The clinical consensus is that red and NIR light treatments are generally safe and effective, with a wide range of potential uses. 

Light is essential for our health and cellular function, just like water, sleep, and the nutrients from food. The human body is designed to function with an abundance of natural sunlight. The truth is, most people do not get nearly enough sunlight spending over 90% of their lives indoors.

Kala provides a simple to use, non-invasive device that allows you to get the therapeutic benefits of light therapy from the convenience of your own home. 

Light therapy is quick: Kala recommends 10 minutes per treatment area. It’s also super easy: all you have to do is sit or stand in front of the device and your body & cells take in the light. Kala treatments are also completely non-invasive and don’t include any ultra violet (UV) rays.

What is red light and near-infrared therapy?

Sir Isaac Newton discovered the spectrum in the 1600s but it took until 1800 to discover infrared light and 1801 to discover ultraviolet.  We found that ordinary sunlight exposure prevented rickets (soft bones that led to bow-legs in children) and osteoporosis or “weak bones”, and even “hunchback syndrome” in the elder population.  We did not know until 1920 that it was because our skin was making Vitamin D3, known as cholecalciferol.

Nils Finsen[i] [1860-1904] essentially invented phototherapy in 1895 when he cured a man of tuberculosis of the skin in just over four days with a strong UV light. The early lights, however, were too powerful to get close to the skin without burning people, and interest faded in phototherapy.

Modern Times

The invention of LEDs reawakened modern interest.  It became safe and simple to create frequencies of 415 nm (blue), 633 nm (red), and 830 nm (infrared) with cool LEDs, without hurting the patient.  While blue light has its uses, red and near infrared light are useful for treating persistent wounds, wrinkles, and scarring; it can even be useful in the treatment of acne.  It is also helpful to reduce the damage of burns, UV damage, and muscle pain, such as tendonitis.

One study revealed that it decreases the appearance of aging by stimulating fibroblasts, the cells that build the structure of your skin, along with collagen and elastin, the elements that make your skin resilient, firm, and youthful.  Another study, in the same year showed that in deliberate exercise excess intended to cause pain, those treated with phototherapy had reduced pain and damage up to 96 hours after the event, compared to the placebo group.

Introducing… Mitochondria!

Two molecules Adenosine Diphosphate and Adenosine Triphosphate are responsible for transferring most of the energy inside our cells.  This happens inside a small cellular component called the mitochondria (sometimes called the cell’s “battery”).  They work together with the triphosphate releasing a phosphate molecule to create energy, and the diphosphate reattaching a new one to “charge” the battery again.  Red light therapy was seen to enhance the activity of the mitochondria, the ADP, and the ATP, making more energy available for all these repairs to proceed.

The Takeaway

Red light has an established history of enhancing metabolic processes, improving repairs and healing.  It is also now GRAS (Generally Regarded As Safe) by authorities, being identified as benign and safe.

For best effect, treatment should be undertaken three times per week, but the cost of clinical sessions can be significant.  Many people are now turning to home units, where a one-time investment can pay dividends for years.  Talk to one of our customer care specialists and find out how Red Light Therapy can change your life for the better!

 

Why is sunlight important for humans?

All energy on Earth is derived from the stars. We do not create energy—that’s impossible—we merely change it from one form to another so it is useful to us. More than 99% of our energy originates within the Sun, arriving here as photons of light. Even the “stored energy” we use here (fossil fuels, etc.) was made with sunlight billions of years ago—so this is solar power, too.

Humans need all the light energy that we receive from the Sun, not only to power our weather and the water cycle, but to allow us to make Vitamin D with our skin, and to moderate the production of serotonin and melatonin to control many bodily functions, such as sleep and wakefulness.

 

Benefits of Kala Therapy Lamp:

The Kala Light Therapy Lamp produces a very bright light. The intensity of the light is measured in lux - the higher the lux, the brighter the light. The light produced from the Kala Lamp stimulates the sunlight that's missing during the dark, gloomy months with our cutting edge 10,000 lux LED's. The Kala Lamp is about 20 times brighter than a regular indoor light.

The light improves SAD by encouraging your brain to reduce the production of melatonin (a hormone that makes you sleepy) and increase the production of serotonin (a hormone that affects your mood). Serotonin also helps reduce anxiety and improve energy levels. Low levels of serotonin have been linked to depression.

A sun lamp with an intensity of 10,000 lux is recommended for SAD. That’s 9,900 lux more than the average standard household light. The Kala lamp's 10,000 lux LED lights mimic the natural rays of sunlight to 98%. A recent study found that results may be seen as quickly as 20 minutes into the first session in improving seasonal depression. The quick results and minimal side effects often provide the first line of treatment against SAD. Not to mention, the Kala Lamp helps to restore circadian rhythms for improved sleep.
