Benefits of Red Light Therapy for Effective Wound Healing

Table of Contents

Due to certain events, we can experience injuries to our bodies. Fortunately, the human body can heal itself but it depends on how severe the wound is. For wound healing, red light therapy is often relied upon by many people.

So what is red light therapy and how can it be useful for healing wounds? Check out this article for more information.

About Wound Healing

When the human body is injured, healing is necessary. The body will process its healing and it can be fast or slow according to the level of the injury. If you have an injury on the surface of your skin, we call it a wound. Wounds can be in the form of burns, scratches from sharp objects, or internal wounds.

As the human body processes wound healing, it will begin the biological recovery process. This recovery process will attempt to replace the damaged tissue. There are generally several biological phases to the healing process.

Wounds generally have two classifications: chronic wounds and acute wounds. If you have a normal body condition, your body will follow the sequence of phases regularly. Wound healing can also be completed within a standard duration in the case of acute wounds. Unlike in the case of chronic wounds, the body no longer follows the normal sequence of wound healing phases.

Wound recovery will also take longer. Usually, these chronic wounds are also more painful. Many factors make the wound healing process longer than usual. If you have a chronic wound on your body, then it is advisable to seek the best solution from a doctor immediately.

Nowadays, there are more and more methods that can be relied upon to accelerate wound healing. One of them is the simple but effective red-light therapy. Apart from healing wounds, many other good benefits of this therapy use a red light-emitting device.

What Are The Stages Of Wound Healing?

Under normal circumstances, the human body will go through four phases to heal a wound. Your body is said to be in a normal state if it can pass through these phases without excessive delays. So, every human has a different duration of healing phases but it becomes a problem if the delay is too much.

Check out the points below on the different phases of wound healing:

– Hemostatic

In the hemostatic phase, the human body will create clots to restrict blood from being transferred to damaged tissues. This hemostatic process can minimize blood loss due to the wound. Hemostatics can also create a barrier that prevents bacteria from entering the wound. Generally, this phase is immediate, hemostatics will finish quickly after the injury and move on to the next phase.

– Inflammation

After hemostatics, it’s on to inflammation. The body sends large numbers of white blood cells to the wound area in response. In this inflammatory phase, inflammation occurs and is characterized by pain and redness. Large numbers of white blood cells can prevent potential infection.

It works by eliminating bacteria that are harmful enough to enter the wound area. The sign of inflammation coming to an end is that the inflammatory cells are no longer needed by the body, and die. This is one of the phases of apoptosis. After inflammation, it will continue to proliferate.

– Proliferation

Several sub-stages occur in the proliferation phase. The first stage is to cover the wound and heal it. Then it will form a scab and coat the wound again and then the next stage is to grow blood vessels in the wound area. Proliferation can take several days. After a few days, the wound will undergo a remodeling process.

– Remodeling

It usually takes about 20 days for the wound to mature. Unlike the other stages, the remodeling phase can last a very long time. Remodeling lasts two years and can be longer than that. During the remodeling stage, the new skin will strengthen.

Physically, the strengthened skin may look quite different when compared to the visual skin in other areas. The skin will then fuse with the skin in the surrounding area. However, in some wound cases, it may create a scar that can vary depending on the severity of the wound.

The skin will strengthen and reduce scarring and eventually disappear completely. To optimize wound healing, one method you can rely on is red-light therapy.

About Wound Healing and Red-Light Therapy

For those of you who want your wounds to heal quickly, then red-light therapy or RLT can be the right solution. You can do this therapy at any phase of healing. RLT can be a low-risk healing therapy option.

This non-invasive therapy involves emitting light to the wound or surrounding area. When the healing waves from the RLT device are absorbed by the skin tissue, the mitochondria can utilize the light to supply energy efficiently.

RLT can not only boost the body’s cells to work optimally, but it can also relieve the sensation of pain or wound inflammation. For the results to be more satisfying and safer, it is advisable to consult with the therapy provider first.

Some Ways Red-Light Therapy Supports Wound Healing

RLT has some amazing mechanisms that can provide many health benefits including wound healing. Check out some of the points below on how RLT can heal wounds.

– Limiting inflammation

There are some signs of acute inflammation such as reddened and swollen skin. Inflammation will continue with the process of producing skin with new structures. Inflammatory processes that are past the initial acute step, can trigger oxidative stress so that the cell’s ability will be damaged so that it cannot function normally as it should.

Red-light therapy can modulate the improved inflammatory response, our body can receive its benefits from the acute inflammatory process and is one of the important components of wound healing.

– Boosting cellular energy

Energy is very important in everyday life. Energy must always be available to do work. Without enough energy, we will be exhausted from doing daily tasks, which can make us unproductive.

There are several ways to get back awake and energized such as consuming coffee or medication. But the results are not very effective and may have certain side effects especially if consumed in excess. If the cells in our body are tired, they cannot support our body’s performance optimally.

You need to keep your cells energized so that your body can perform at its best. NIR or red light that is exposed through light therapy devices can be absorbed into the skin, including the mitochondrial chromophore area. This interaction can trigger the production of good energy in the mitochondria.

In particular, RLT can stimulate ATP to be produced more. If the body’s cells have enough ATP energy, then they can perform their duties well. They can fight pathogens at their best and can support the regeneration process.

– Maintain stable collagen production

RLT can also make collagen production normal or uninterrupted. Collagen can be found in various areas of the body, it is one of the important components that can support wound healing. Collagen plays an important role in restoring normal tissue.

With RLT, it can help produce healthy collagen in the scar area (deepest layer). Collagen management can help the formation of healthy tissue. This benefit of RLT can also prevent scar formation.

– Stem cell activation

The next way RLT works is stem cell activation. Stem cells will go to the injured area when the skin is rebuilt. They can develop to become other important cells that the human body needs. Performing red-light therapy can trigger the activation of stem cells so that stem cells can move gradually to the wound area.

Stem cells that spread can trigger communication between cells. So that damaged cells can make certain signals to new cells. With stem cells replacing poor-quality cells, the new cells can get the right signals. The characteristics of the damaged cells will not be taken away, as the new cells are more likely to get the ideal characteristics needed for wound healing.

What Are The Barriers To Wound Healing?

Red-light therapy can be quite effective in healing wounds. But you should also be aware of certain barriers that make wounds difficult to heal. Wound healing depends on the internal condition of the body, the growth of new tissue and the body’s immunity can affect how quickly or slowly the wound heals.

When your wound heals slower than the standard duration, certain factors cause this. Before you do red-light therapy, it is better to know some of the factors that hinder wound healing below:

  • Lifestyle that does not support wound healing. If your lifestyle is unhealthy such as taking harmful drugs, smoking, excessive alcohol consumption, and so on, it can hinder the wound healing process.
  • An infected wound is another factor. If your wound is infected, then the infection can damage the quality of the new cells and may even cause them not to function normally.
  • Chronic stress can harm the performance of the human immune system. This condition can make the parasympathetic nerve function not perform optimally. Parasympathetic itself is in charge of controlling various functions, one of which is repairing the human body.
  • Circulation disorders, this condition can occur because the body does not have enough good nutrients and oxygen circulating through the bloodstream. Another reason is lymph disorders.
  • Taking certain medications that interfere with the wound healing process. Some medications may not have a good enough impact on the healing process. You need to reconsider taking NSAIDs, corticosteroids, and chemotherapy if you want your wound to heal quickly.

Those are some of the barriers to wound healing, other barriers include chronic inflammation and mitochondrial dysfunction. Knowing some of the points above can make it easier for you to start doing red-light therapy sessions safely and smoothly.
