What Is Red Light Therapy?

Light therapy, also known as photobiomodulation, is a natural, non-invasive therapy option that shines beneficial wavelengths of light onto your skin to treat wrinkles, scars, wounds, among other conditions. While there has been proven evidence to show that red light therapy (RLT) is a promising treatment for certain conditions, there is still a lot of research to be done to learn more about how this specific therapy option works. Full-spectrum light includes many colors, including certain wavelengths that are not visible to the human eye, but only a select range of red and near-infrared light is clinically proven to be therapeutic for the purposes of light therapy. Genuine and high-quality light therapy products emit specific wavelengths of red and near-infrared (NIR) light using medical-grade LED technology. These LEDs give off clinical doses of light to your skin and unlike other laser therapies or tanning beds, RLT devices omit any heat, excess UV rays, harmful chemicals, and any major side effects.

How Does Red Light Therapy Work + How Is It Used?

Research has shown that red light produces a biochemical effect in cells that strengthen the mitochondria (where the cell’s energy is created). By increasing the function of the mitochondria, a cell can make more ATP (adenosine triphosphate), the energy-carrying molecule found in cells of all living things. With more ATP, cells can function more efficiently, rejuvenate themselves, and repair damage.

Red light has the ability to penetrate the top layer of skin (without any damage to tissue) and into the deep levels of skin- the dermis. The dermis is where collagen, elastin and other proteins inhabit. There is still a lot of clinical research to be done about RLT, but at the moment there is evidence suggesting that red light therapy may have the following benefits:

  • promotes tissue repair and stimulates the healing of wounds
  • improves hair growth in people with androgenic alopecia
  • short-term treatment of carpal tunnel syndrome
  • reduces psoriasis
  • ideal for mild treatment of acne
  • helps with short-term pain relief and inflammation
  • improves skin complexion by building collagen to diminish wrinkles and scars
  • helps heal damage caused by the sun
  • heals cold sores
  • improves the health of joints

RLT can be performed in a professional setting or with an at-home device. These tools often come in a large variety of shapes such as handheld wands, stand-up panels, in the form of a face mask, full-body bed, and caps. Many salons, gyms, and spas offer red light therapy for cosmetic and muscle recovery applications. You may find FDA-approved devices online that you can purchase and use personally at home, but make sure to read the manufacturer’s instructions carefully! Listed below are some RLT options for at-home use.

In addition to the benefits listed above, here are some ways in which red light therapy might also influence sleep:

  • Melatonin Regulation: Red light therapy may help regulate the production of melatonin, a hormone that plays a crucial role in sleep-wake cycles. Exposure to red light in the evening may support the natural circadian rhythm by promoting melatonin production.
  • Improved Sleep Quality: Some studies suggest that red light therapy could enhance overall sleep quality. This might be attributed to its potential to improve blood flow, reduce inflammation, and support cellular function.
  • Reduced Sleep Disruptions: Red light therapy may help reduce sleep disruptions, such as waking up during the night. By positively influencing cellular function, it could contribute to a more stable sleep pattern.
  • Stress Reduction: Red light therapy has been linked to reduced stress and anxiety levels. If stress is a contributing factor to sleep difficulties, the relaxation induced by red light therapy could indirectly support better sleep.

It’s important to note that while there is some promising research, the evidence on the effectiveness of red light therapy for sleep is still emerging, and more studies are needed to establish its benefits conclusively. Additionally, individual responses to red light therapy may vary.

Please keep in mind that results will vary from person to person and they are typically subtle after your initial sessions using red light therapy. The current research appears that this type of treatment is promising, but more studies are needed to determine how exactly red light therapy works and how it can be most beneficial to people using it.
