LED Light Therapy and Chronic Inflammation

Chronic inflammation is a significant contributing factor of a variety of chronic health conditions, having a tremendously adverse effect on our health. LED Light Therapy — also known as photobiomodulation (PBM) or low-level laser therapy (LLLT) — has been making headlines in recent years as a highly effective new treatment for chronic inflammation.

Perhaps most remarkable is the gentle nature of LED Light Therapy itself — noninvasive, drug-free, almost universally reported as pain- and discomfort-free, and often far more cost-effective than various other treatments, procedures and medications, most of which carry their own risks and side effects.

And with the option for self-treatment, LED Light Therapy is saving home users around the world thousands of dollars, as well as months if not years spent on a wide spectrum of traditional roller-coaster treatments that often provide less-than-reliable results.

Let’s explore some of the evidence.

Light Therapy & Dementia

Emerging evidence has begun to show that dementia is caused by more than just changes to our neurons and neural pathways — neuroinflammation may also play a significant role.

This 2021 study (Nizamutdinov et al., 2021) notes how low emission of transcranial near-infrared (tNIR) light has a wide array of benefits on the brain, including increased oxygenation, improved regional circulation and beneficial regulation of inflammation.

Additional studies on the benefits of Light Therapy for traumatic brain injury (TBI) and the possibility of Light Therapy as a preemptive maintenance treatment for a healthy brain further show the tremendous potential of transcranial photobiomodulation (tPBM).

Light Therapy & Diabetes

From diabetic retinopathy and foot ulcers to chronic wounds and more, diabetes causes a wide range of chronic issues, many of which involve inflammation.

It has been found that Light Therapy aids these symptoms in a number of ways, including mitigation of inflammation, pain relief, tissue repair and regeneration, and more.

Scientific reviews like this one (Leyane et al., 2021) highlight the myriad of ways light therapy is being studied to alleviate many diabetes-related conditions — most all of which conclude that Light Therapy is a highly viable treatment option with incredibly exciting potential.

Light Therapy & Heart Disease

Recognition (Geovanini & Libby, 2018) continues to mount that inflammation plays a key factor in the hardening of the arteries, leading to chronic heart disease, heart attacks and more.

Alongside this growing belief, exploration into Light Therapy’s potential to aid the cardiovascular system continues, with one study (Tuby et al., 2008) finding up to a 70 percent reduction in infarct size and ventricular dilatation, along with a cardioprotective effect on mitochondria and enhanced angiogenesis — the growth of blood vessels from existing vasculature — in rat and canine models.

We look forward to seeing future studies and potential applications for Light Therapy on the complex issue of chronic heart disease and the role chronic inflammation may play. Be sure to sign up for our newsletter to receive the latest news!

Light Therapy & Other Forms of Chronic Inflammation

Even more established than all of the above is Light Therapy’s efficacy with other chronic and recurring conditions involving inflammation. From arthritis and tendonitis to dermatitis and more, Light Therapy has been found to be a highly effective treatment for many common ailments and conditions, including:

The Visum Light & Chronic Inflammation

Of the many handheld Light Therapy devices available today, only the patent-pending Visum Light is designed with the future in mind.

With its polychromatic capabilities and dosage, duration and Nogier Frequency settings, it’s one of the only devices on the market immune to obsolescence — allowing it to serve medical practitioners, veterinarians and home users alike for many years to come.

And with its 45-day No-Worries Guarantee and convenient financing, you can try your new Visum Light right away, with absolutely no risk.
