What Is Infrared & Red Light Therapy?

Red light therapy (RLT) is an emerging treatment that uses red low-level wavelengths of light to treat skin issues such as wrinkles, scars, and persistent wounds among other conditions. It has also reported to help treat or improve chronic diseases of the nerves and bones, such as arthritis, insomnia, depression, etc.

Red and near-infrared light are those parts of the electromagnetic spectrum, and more specifically, the sunlight spectrum, that favor plant and animal growth. The next photo shows the types of light that affect how our cells function.

History of Infrared & Red Light Therapy

RLT has been around since ancient times when the therapeutic red light was first discovered using solariums which would filter out other wavelengths to get a pure red light from the sun by using tinted and colored glass.

History of rlt therapy
  • Began in 1903, RLT inventor, Niels Finsen, won the Nobel Prize in Medicine for it.
  • The 1960s: Began to be used in the treatment of chronic pain, arthritis, joint rehabilitation, and soft tissue injury.
  • The 1980s: Humans discovered infrared therapy and began to apply it to wound healing and healthy beauty.
  • The 1990s: It was found that RLT can significantly promote the repair of sports trauma tissue.

NASA originally began experimenting with RLT on plant growth in space and then to help heal wounds in astronauts. Like many developments, other potential uses began to be investigated. Now, Red light, blue light, and infrared light therapy have a large amount of mature data and are widely used in skin diseases, Pain treatment, medical cosmetology, and other fields that have received strong support from many medical experts and groups.

Infrared & Red Light Therapy Benefits

RLT is considered a natural remedy, and the following are some of its wide-ranging areas of use.

Skincare:

RLT is promoted as a treatment for some common skin conditions, including: Reduce and smooth wrinkles, fine lines, stretch marks, age spots. Improve facial texture, acne, psoriasis, rosacea and eczema, scars, sun-damaged skin ect.

benefits of red light therapy

Relief Pain:

One study found red and infrared light therapy cut osteoarthritis-related pain by more than 50%. It relieves symptoms associated with joint pain, muscle soreness, autoimmune disease, traumatic brain injury and spinal cord injury. By increase blood vessel diameter and improve blood circulation to reduce overall pain.

Reduce Recovery Time:

For high-performance athletes (and those who train like them), LED light therapy can help speed muscle repair after fatigue and injury. Mitochondria in cells are particularly sensitive to LED light therapy, and they are abnormally abundant in muscle cells. LED light therapy can also stimulate stem cells, further aiding muscle recovery.

Hair Loss:

Hair loss is a common condition, affecting 50% of men over the age of 40 and 75% of women over the age of 65. Studies have shown that LED light therapy can stimulate hair growth. Red light wavelengths are thought to stimulate the epidermal stem cells in the hair follicle, causing the follicle to enter the anagen (active growth) stage.

Improve Fertility:

Around age 30, testosterone levels in men naturally begin to decline. Men looking to naturally increase their libido, sexual satisfaction, fertility and physical performance can benefit from LED light therapy. Red and near-infrared wavelengths can stimulate photosensitive proteins in the testes, resulting in higher testosterone production. Other research suggests that low-intensity light therapy may affect the pineal gland in the brain, which has a major impact on reproduction.

How Red Light Therapy Works

Red light therapy, also known as low-level laser therapy (LLLT) or photobiomodulation, harnesses specific wavelengths of light to penetrate the skin and reach cells. It usually uses light emitting diodes (LEDs) that emit red light in the range of 620-750 nanometers. Here’s how it all comes together to provide relief:

how red light therapy work

Cellular Impact

  • Absorption by Chromophores: When red light is absorbed by chromophores within the mitochondrial cells, it jump-starts a series of biological processes. These are the same mitochondria responsible for the production of adenosine triphosphate (ATP), the energy currency of cells.
  • Increased ATP Production: With increased ATP production, cells have more energy to perform repair and rejuvenation processes. Think of ATP as fuel, powering the healing response in damaged tissues.

Anti-Inflammatory Effects

  • Red light therapy is shown to reduce inflammation, a root cause of many chronic pain conditions. By decreasing the production of pro-inflammatory cytokines, it can effectively lower inflammation levels and ease pain.

Enhanced Blood Flow and Circulation

  • The increase in blood flow from red light therapy can be crucial for healing. Improved circulation means more oxygen and nutrients are delivered to damaged areas, speeding up the recovery process.
  • Enhanced circulation doesn’t just help heal wounds; it also reduces pain and stiffness in muscles and joints.

Collagen Production

  • The therapy stimulates the production of collagen, which is essential for skin, tendon, and ligament health. Increased collagen helps in alleviating joint pain and improving skin elasticity.

Muscle Recovery and Growth

  • Reduction in Muscle Soreness: Regular use can lead to reduced muscle soreness after exercise or physical activities.
  • Enhanced Muscle Repair: It boosts the repair process, reducing the time it takes for muscles to recover.

In summary, red light therapy interacts at a cellular level, reducing inflammation, improving circulation, and accelerating tissue repair, making it an effective treatment for a variety of conditions.

MAYBE YOU ALSO HAVE THESE QUESTIONS

1.Is red light therapy safe?

It is generally considered safe and is not associated with any side effects, at least if used as directed. RLT uses very low levels of heat and doesn’t hurt or burn the skin. This therapy is not toxic, not invasive, and not the same type of light used in tanning booths, and it doesn’t expose your skin to damaging UV rays. We suggest that it is either wearing goggles or keeping your eyes closed during use, as long as you use an FDA-cleared device at its recommended dosage.

2.How long does it take to see results?

The amount of time it takes to see results from RLT can vary depending on the individual. Generally, it takes 2-3 weeks for treatment to see results. Some people may see results in as little as a week, while others may take up to 6-8 weeks before noticing improvements. However, according to the feedback from customers who have used our products for more than 3 months, they have a very obvious improvement after using RLT.

3.Is red light therapy effective?

RLT is an emerging treatment that’s generating growing interest. Many of the published studies using RLT show the results so promising, and more quality studies with larger numbers of people are needed. RLT has many potential benefits has been proven. It provides an effective treatment for skin conditions, dental pain, inflammatory conditions, and other chronic health problems.

4.Is at-home device use a safe, reasonable option?

In addition to medical office-based use with a purchased device, you may see RLT being promoted at beauty spas and salons, saunas, tanning salons, gyms, and wellness centers. In fact, at-home RLT devices are also safe. If you’re using an at-home device, follow the manufacturer’s instructions, and you should be good.

5.What is the cost of red light therapy?

The cost of RLT can vary depending on where you go for the treatment and how long you receive it. The average cost of a 10-to-15-minute session ranges between $25-$200. But if you have an at-home RLT device, your cost will save a lot, and also save your time.

Where Do I Get RLT?

It’s usually done in a doctor’s office or some salons. You can also buy a RLT device at home. When shopping for a RLT device, it’s important to keep the following features in mind: (1) FDA clearance, (2) Power of the device, (3) The target area of your body.
