Red Light Therapy for Bites and Bruises - Does It Help?

Red light therapy (RLT) has gained popularity for its various health benefits, ranging from skin rejuvenation to pain relief. But how effective is it when it comes to treating bites and bruises? This article delves into the science behind red light therapy and explores whether it truly helps in healing these common injuries.

What is Red Light Therapy?

Red light therapy involves exposing the skin to low levels of red or near-infrared light. Unlike ultraviolet (UV) light, which can damage the skin, red light is believed to be safe and beneficial. It penetrates the skin's layers, reaching the tissues and cells below. This therapy is typically delivered using devices like LED panels, an infrared  sauna, laser devices, or specialized beds and masks. 

How Red Light Therapy Works

Red light therapy works by stimulating cellular activity. When red light penetrates the skin, it is absorbed by the mitochondria, the powerhouse of the cell. This absorption increases the production of adenosine triphosphate (ATP), which is the energy currency of the cell. More ATP means cells can function more efficiently, repair themselves, and rejuvenate faster.

Benefits of Red Light Therapy

Red light therapy has been shown to provide a range of benefits, including:

  • Wound Healing: Accelerates tissue repair and regeneration.
  • Pain Relief: Reduces inflammation and pain in muscles and joints.
  • Skin Health: Improves skin texture, reduces wrinkles, and helps with conditions like acne and psoriasis.
  • Enhanced Recovery: Speeds up recovery from injuries and surgeries.

Red Light Therapy for Bites

Bites from insects or animals can lead to swelling, redness, and pain. Red light therapy can potentially help in several ways:

  1. Reducing Inflammation: Red light therapy has anti-inflammatory properties, which can reduce the swelling and pain associated with bites.
  2. Promoting Healing: By increasing cellular activity and blood flow, red light therapy can accelerate the healing process of the bite area.
  3. Pain Management: The therapy can help manage the pain that often accompanies bites by soothing the affected tissue.

A study published in Photomedicine and Laser Surgery showed that red light therapy significantly reduced inflammation and promoted healing in skin wounds. While the study did not focus solely on bites, the principles of wound healing can be applied to insect or animal bites.

Red Light Therapy for Bruises

Bruises occur when small blood vessels under the skin burst, causing discoloration and pain. Here's how red light therapy might help:

  1. Improving Blood Flow: Red light therapy enhances blood circulation, which can help clear the trapped blood in bruises faster.
  2. Reducing Swelling: As with bites, the anti-inflammatory properties of red light therapy can reduce the swelling and discomfort of bruises.
  3. Speeding Up Healing: The increased cellular activity and ATP production can speed up the body's natural healing process, making the bruise fade quicker.

In a review published in the Journal of Clinical and Aesthetic Dermatology, red light therapy was noted for its efficacy in reducing inflammation and promoting healing, supporting its potential benefits for treating bruises.

Practical Application of Red Light Therapy

Using red light therapy for bites and bruises is straightforward. Here are some practical steps:

  1. Choose a Device: There are various red light therapy devices available, from handheld units to full-body panels. Choose one that suits your needs and budget.
  2. Follow Guidelines: Each device comes with instructions for use. Generally, sessions last between 10-20 minutes, and it is recommended to use the therapy several times a week for best results.
  3. Maintain Consistency: Consistent use is key to seeing benefits. Regular sessions will help maximize the healing effects on bites and bruises.

Safety and Side Effects

Red light therapy is generally considered safe with minimal side effects. Some people might experience mild discomfort or redness after the treatment, but these symptoms typically subside quickly. It is essential to follow the manufacturer's guidelines to avoid any adverse effects.


Red light therapy presents a promising, non-invasive option for treating bites and bruises. Its ability to reduce inflammation, enhance blood flow, and speed up cellular repair makes it a valuable tool in managing these common injuries. While more research is needed to fully understand its efficacy, the existing studies and user testimonials suggest that red light therapy can be an effective addition to your health and wellness routine. Whether you're dealing with a pesky insect bite or a painful bruise, red light therapy might just be the solution you need for faster, more efficient healing.
