Benefits of Light Therapy On Chronic Pain

Light therapy is a type of treatment that uses light to improve various health conditions. It has been used to treat chronic pain since at least the early 2000s and has become more popular in recent years due to its effectiveness and relatively low cost.

In this article we'll discuss what light therapy is, how it works for treating chronic pain, and the most common types of light therapy that you might consider trying.

What is light therapy?

Light therapy is a non-invasive treatment for pain that uses light to reduce inflammation. Using LEDs (like those in Phera red light therapy torch device), the light triggers biochemical changes within cells and stimulates cellular activity in order to achieve therapeutic benefits.

This kind of therapy can help with chronic pain, nerve pain, and inflammation. Light therapy has been shown to help with migraine headaches, fibromyalgia, and arthritis.

Is light therapy backed by science?

Light therapy is not a new form of treatment, noninvasive, and relatively safe when used correctly. It's been used for decades to treat Seasonal Affective Disorder (SAD) and other conditions, and the results are backed by science.

It's a fact that light therapy was approved by the FDA for pain control in 2002, but it is used far more widely in Europe and Australia than in other countries. In recent years there’s been progress in understanding how light works at the molecular and cellular level. Recent research explains how a single brief exposure to light can have effects lasting for hours, days, or even weeks.

What kinds of pain does light therapy treat?

In fact, light therapy could be used on any body part to treat any type of chronic pain. These include, but are not limited to, the following:

  • Muscular back pain

  • Back pain

  • Whiplash injury

  • Post-surgical pain

  • Carpal tunnel syndrome

  • Sprains

  • Strains

  • Complex regional pain syndrome (CRPS)

  • Tendinitis

  • Migraines

  • Neck pain

  • Rheumatoid arthritis

  • Osteoarthritis

Light therapy can be used as a pain management tool. A recent NPR article explains how they work:

“The LEDs work by stimulating cells in your eyes called photoreceptors. When that happens, chemicals are released that send signals to your brain's nerve endings. The result is less pain or better sleep."

Mayo Clinic also has some great information about how light therapy works and who it might benefit, "Pain Management: Light Therapy May Help Those With Chronic Pain."

Types of light therapy

There are three main types of light therapy:

  • Blue light therapy, or photobiomodulation, which uses blue wavelengths of light to reduce inflammation and promote healing. It may help prevent or reduce acne breakouts by curbing the sebaceous glands’ production of oil.

  • Red light therapy, also known as low-level laser acupuncture or soft laser therapy, uses red wavelengths to stimulate blood circulation and increases the rate at which cells regenerate. Applying red light can help diminish the appearance of scars, age spots, and inflammation by stimulating collagen production.

  • Infrared (IR) radiation is similar in wavelength to sunlight and is invisible to the naked eye. Infrared heat may penetrate the skin on a deeper level, increase cell permeability, increase skin elasticity, speed up healing, reduce pain and swelling, and decrease wrinkles and lines.

Benefits of light therapy

Light therapy offers a plethora of benefits considering it is safe and non-invasive.

Some of the benefits include the following:

  • Reducing pain by reducing swelling and increasing blood flow to the area. This can help with muscle aches, joint pain, or headaches.

  • Improving sleep by helping your body produce melatonin that regulates your circadian rhythm (your biological clock). This will help you fall asleep faster at night and wake up feeling more refreshed in the morning.

  • Lowering depression symptoms because light can stimulate serotonin production in your brain, which improves moods over time as well as provide relief from seasonal affective disorder (SAD) during winter months when days are shorter than usual causing depression symptoms such as low energy levels or irritability due to lack of sunlight exposure, which impacts serotonin levels adversely leading us back into winter blues again!


Overall, light therapy is a safe and effective treatment for pain. It can be used to treat a variety of chronic pains, including headaches, arthritis, fibromyalgia, and even carpal tunnel syndrome.

The different types of light therapy work by reducing inflammation in the body via increased blood flow and metabolism of tissues. A form of light therapy also helps reduce stress levels through relaxation responses such as sleepiness or drowsiness that occur during exposure to bright light (which can be helpful for those who have trouble sleeping).

Thankfully, you don't have to spend money on expensive red light therapy sessions at salons or medical offices anymore; you can use this form of treatment at home or while you're on the go.

If you want to go deeper with your healing, you might want to consider using the Phera red light therapy torch. In addition to 630 and 660nm (red light), our device also emits 850nm and 900nm (near-infrared) that can help you reach deeper into soft tissues, muscles, joints, and bones. The 460nm and 470 nm (blue light therapy) can also be used to destroy bacteria and improve skin inflammation, inhibit excessive oil secretion and reduce acne, black heads, and enlarged pores.

For full skin-to-bone healing, consider using a Phera red light therapy torch device, a one-of-a-kind 5-wavelength device. The best part - our light therapy torch device comes with a pulse mode.

Research reveals that the cells in the body have what is called a “quench period”—a pause of only a few milliseconds (PULSE MODE) when they are most receptive to light therapy. This short pause makes a big difference, allowing cells that are under oxidative stress to respond even better to light.

Finally, it's important to note that most people who try this type of treatment report no negative side effects from using it.
