Everything You Need to Know About Red Light

You may have heard that Red Light Therapy (RLT) is now an FDA-approved health and wellness procedure. You may find it safe, painless, and effective compared to invasive and harsh cosmetic methods with serious side effects and risks.

RLT is no longer a scientific research item; it is now embraced by people of all ages and divided for its benefits and ease of use. For personal use, you can easily find Red Light Therapy devices in gyms, spas, dermatologists’ offices, and at home.

What is Red Light Therapy

Red light therapy [1](RLT) is a division of light therapy. Red Light Therapy refers to treatments that use wavelengths of red and near-infrared light from light emitting diodes (LEDs) to stimulate, heal, and regenerate any damaged muscle tissue in your body.

RLT comprises two forms of electromagnetic energy – red light and near-infrared light. You can see red light with your naked eye, unlike infrared light. Your doctor may use this treatment to treat numerous diseases and conditions.

Suppose you have wounds on your skin; RLT may heal your wound faster. Your skin may be lax due to advancement in age; the treatment may tighten your skin, reduce the wrinkles and make you appear younger.

The most common uses its known for include; pain relief, functional restoration, and inflammation reduction. Other names for red light therapy include;

  • Soft laser therapy
  • Low-level laser therapy (LLLT)
  • Photobiomodulation (PBM)
  • Low-power laser therapy (LPLT)
  • Photonic stimulation
  • Biostimulation

History of Red-Light Therapy

Low-level laser therapy (LLLT) goes way back to the Egyptians, Indians, and Greeks in medieval times. Still, it has gained ground in recent years for its widespread use in medical and physiotherapy practice.

However, the modern renaissance in ‘light as therapy’[2] was begun by Florence Nightingale, who, in the 1850s, advocated the use of clean air and an abundance of sunlight to restore health.

Modern light therapy (phototherapy) increased in use after the Nobel award winner Dr. Finsen proved that tuberculosis scarring could be treated using Ultraviolet (UV) light in the late 19th century, and treatment of smallpox scarring with red light.

Since the 1950s, health caregivers in countries such as Australia, Scandinavia, the USA, England, and Canada have been treated with light, particularly UVB light.

Further research by NASA[3] in the early 1990s produced results that you find being used in hospitals and homes today for therapeutic purposes.

In 1993 Quantum Devices, an electronics company created an LED for NASA to grow plants in space. Besides growing plants, the device could heal the NASA personnel’s skin wounds.

The discovery led to rigorous research by NASA scientists on how LEDs can be used to enhance the functions of the human cells to promote healing. Low-Level Laser Therapy (LLLT) was approved for use by the FDA in 2003.

Initially, you could only access this type of treatment in a confined environment as laser treatment was very expensive and needed to be handled by someone with the required technical know-how. Right now, you may be able to purchase a red-light therapy LED device to use at home safely.

What does Red Light Therapy do?

Red light has been proven to affect many different ailments positively. Your condition requires a specific wavelength, strength, and amount of time you expose yourself to the red light for treatment. For example, RLT treatment for acne may vary from treating inflammation in the brain.

The red-light wavelengths penetrate your skin to a distance of about 8 mm, depending on its strength and wavelength. Your cells’ mitochondria soak up the red light and make more energy which in turn helps the cells to repair themselves -becoming healthier, and also triggers healing in your skin and muscle tissue.

Your body cells’ source of energy-adenosine triphosphate (ATP) is generated more after the mitochondria chromophores absorb the light photons.

Which wavelengths are used in Red Light Therapy?

A longer wavelength ranging between 600nm and 1100nm may be required to treat you if the damage on your skin has penetrated deep into your tissues. 390 nm to 600 nm is a wavelength range mostly used to treat superficial tissue on the surface of your skin. The following are some of the wavelengths used for different types of treatment and interventions;

  • Red light therapy- 625nm – 1100nm.
  • Visible red light – 620 – 750nm.
  • You may not be able to be treated with red light with a wavelength of between 700 nm and 750 nm since no biochemical activities are present in this range.
  • Near-infrared therapy lights -750nm – 1100nm.

The longer the wavelength of light, the deeper it will sink into/penetrate your skin.

Red Light Therapy uses 

A report by medical news today highlighted that Red light therapy is suitable for a wide range of issues[4], including well-being and medical. The FDA approves RLT mainly for pain relief, restoring function, and reducing inflammation.
