Does Red Light Therapy Help Heal Wounds?

Having a wound that doesn’t seem to heal can be terrifying. You may be confused and ask yourself if it will ever heal the wound or if it will be on your skin forever. So, how can you take a good wound care?

With the best red light therapy, you can expect that you might make the wound heal faster than ever with your consistency and work. So, does red light therapy help heal wounds, or is it just another lie?

You may not believe us, but you might ask hundreds of people who have great experiences with this therapy and their possible outcomes.

Does Red Light Therapy Help Heal Wound?

The term “wound” refers to an open wound, which occurs whenever the skin ruptures, such as a cut, scratch, scrape, or puncture. Internal injuries can harm cartilage, arteries, blood vessels, and other important organs. These injuries may result in serious repercussions if they don’t recover fully.

The primary barrier separating the human body from the outside world is the skin, the largest organ in the body. The skin is vulnerable to wounds like cuts, lacerations, burns, and pressure sores because it serves as the body’s first line of defense.

Red light therapy is a quick procedure that can be finished in under an hour by exposing the body using low-wavelength red light. Although RLT is probably more frequently used in practice, the procedure is also known as low-level laser light therapy.

So, does red light therapy help heal wounds? Yes, the cells may absorb and use this natural red light because it can reach deep within the skin.

Skin cells contain mitochondria, which can absorb light particles. The elevated levels of adenosine triphosphate, which provides energy to all cells, might be aided by this technique.

Skin wounds and scars

Inflammation and swelling are common after injuries and operations; they are painful, slow recovery, and reduce action. In multiple initial research, red light therapy might reduce intense inflammation.

Many studies have already explained how cells might create new blood vessels and fibroblasts when exposed to regular light. Due to the new tissue arrangement, the wounds and scars might heal faster, with less pain, meaning that the whole process of wound healing is a lot simpler for the patient.

Red light therapy uses particular light wavelengths to possibly enhance healthy biological body functions regarding tissue regeneration. The most advantageous wavelengths for red light treatment are red light in the 630–660 nm range and near-infrared light in the 810–850 nm range.

Near-infrared light therapy for wounds might be most effective when it penetrates deeper into the body. NIR and red light therapy might effectively treat muscle, bone, and connective tissue wounds.

Low-level laser light treatment devices were the first method of delivering red light. Recent advances in light-emitting diode (LED) light technology have made red LED wound therapy more accessible.

Red or near-infrared wavelengths of light might cause the skin’s cells to produce more energy as a reaction; as a result, cells might function at their best. Red light therapy might have a profound effect on how quickly wounds heal.

Treatment with red light might have immediate effects on the cells. The enhanced functionality of individual cells might support various bodily systems and speed up wound healing by stimulating collagen.

How to Use Red Light Therapy for Wounds

Doctors should always treat wounds that require medical attention. Red and NIR light therapy can be administered to minor wounds that don’t need medical attention using LED panels with high light energy output. Read the crucial points below for the best results from low-level light treatment.

Until the affected area is healed, treatment should be administered several times weekly for between ten and 20 minutes. Always keep the wound clean. Getting enough sleep, eating well, and managing stress may give your body the necessary nutrients.

Furthermore, use a light-emitting diode (LED) panel for light therapy for the best possible outcomes. Portable, battery-powered devices cannot reach the deeper layers of the skin and underlying tissue. So, integrate an LED panel with red and infrared lighting. Moreover, it’s important to treat wounds completely, starting at the surface.

Additionally, a chronic wound requires daily care for at least four weeks and takes an average of 47 days to possibly heal, depending on many variables (such as your nutrition). 

Healing might occur in as little as three days; however, some people may need months. A natural, risk-free treatment that might prevent infections and amputation is unquestionably worthwhile.

Red light therapy has been shown to possibly hasten wound healing in numerous independent clinical studies, animal studies, and in vitro lab experiments.

Additionally, you’ll learn that while you’re possibly healing a wound, you might also benefit from some of red light’s more pervasive advantages, like you might get improved skin health or quicker muscle recovery after a strenuous workout. 

While you might be healing from the inside, your skin might also be glowing on the outside. So, everyone should have red light therapy devices at home.
