Red Light Therapy 101: The Rundown

Red Light Therapy 101: The Rundown

Introduction

Red Light Therapy also known as low-level light therapy (LLLT) is a hassle-free alternative in the diverse world of medicine.

Presently, the human eyes are unable to detect the type of light utilized in Red Light Therapy.

The light or lasers used in the therapy emit a non-painful heat, typically Red light and Infrared light within the range of 600 to 800 nanometers to treat various skin conditions, which improves the body’s blood circulation, which in turn helps relieve pain.

According to the Journal of Clinical and Aesthetic Dermatology, recent developments in the usage of light-emitting diodes (LEDs) have sparked interest in their therapeutic application in a range of medical and aesthetic applications.

Different wavelengths of light are employed depending on the target chromophore.

For the longest time, prescription medicines have been the gold standard in the healthcare system for pain treatment.

Unfortunately, depending on them posed a high number of risks to long-term health and research has also found prescription medicines to be addictive. Red light treatment, on the contrary, is a non-addictive and interchangeable alternative in contrast to conventional medicines.

In short, Red light therapy amps up your natural bodily functions to help you heal quicker.


The stimulation of stem cells is probably one of the most important effects of LLLT exposure. When activated, stem cells go to the damaged region via the circulation, where they change into the required cell type. Red and infrared light, for example, has been discovered to stimulate stem cells in the bone marrow, allowing them to recover.

What is Red Light Therapy?

Low-level light therapy or LLLT has found great success in the treatment of skin.

Prior to its testing on human beings, Red Light Therapy was tested on plants at a NASA space station.  The plants responded well to the treatment and allowed for more research into light therapy to become a reality. NASA had utilized red light therapy to stimulate quicker cell development and improve wound healing.

Helping cancer patients cope with the side effects of chemotherapy as well. Red light, which works on the same premise as blue light, stimulates collagen synthesis, which is necessary for maintaining youthful and firm skin.

The use of red light therapy as an anti-ageing treatment seems promising, according to NASA’s extensive research.

According to a Pubmed led research analysis, Red light therapy-based publications saw a steep rise after the year 2000.

Mostly focusing on the benefits of red light therapy based on the test results that found success in the treatment of osteoarthritis, carpal tunnel syndrome, and tendinopathy. For all beings with bones, healthy joints are crucial to preserving one’s mobility and freedom.

Red light therapy has been shown to enhance joint health by lowering discomfort and lengthening the time between retreatments. While red light may not have been as successful as the green light, the objective of the therapy was to help the patient’s body recuperate, reenergize, and rebuild itself.

Pros and Cons
Pros

1. Red light therapy has been shown to be beneficial in the treatment of wounds and tissue healing in studies. Inflammatory cells are reduced by red light treatment, which improves healing. An increase in collagen and fibroblast synthesis happens as a result of the formation of newly activated blood cells (angiogenesis).

2. Red light treatment increases blood flow by boosting cell energy to produce physiological responses such as increased blood flow. Blood flow is improved, which means the body is better able to recover and function.

3. The production of nitric oxide is a common side effect of being exposed to red and infrared light wavelengths. The production of nitric oxide improves blood circulation, allowing more nutrients and oxygen to reach damaged tissues. This assists in the repair and regeneration of wounded tissues, reducing pain and inflammation. When compared to typical pain treatment procedures, red light therapy is a less intrusive and safe option.

Cons

  1. Red light treatment also has the advantage of being safe. There have been no instances of LLLT causing damage to a specific skin type. It should be emphasized, however, that excessive exposure to any light can be harmful. As a result, it’s critical to use light therapy in moderation. In general, red light treatment for skin can help with a variety of ailments.
  2. Due to its length of treatment, Red Light Therapy can be time-consuming and expensive.


3. When the red light was excessively strong or the patients had contraindications, only modest short-term adverse effects were seen (such as photosensitivity, taking light sensitizing drugs, and certain diseases). Eye strain, transient headaches, and minor visual side effects are the most common adverse effects. They don’t signify any long-term changes and go away within a few hours or days.

Benefits

Red light therapy is a long-term treatment that is frequently utilized in addition to the main recommended treatment.

However, because light therapy is a non-invasive, painless, chemical-free, drug-free, and simple to use treatment, you may obtain light therapy sessions at home and save money and time.

Light treatment has so far been shown to have no significant adverse effects. They may or may not be present, but long-term clinical trials have yet to establish this.

However, given the potentially significant side effects of many medicines, red light treatment is a more effective and safer alternative.

The prospect of alleviation from chronic illnesses such as Joint Pain Relief is one of the most important health advantages of Red Light Therapy. This is why it is used to treat both physical and psychological issues.

Red Light Therapy promotes tissue healing and has been shown to have anti-inflammatory properties. Patients may notice a considerable reduction in chronic joint pain and swelling if the tissue can repair itself to a healthy state.

Red light therapy helps people with mood disorders like SAD by providing artificial light at times when seasonal changes produce continuous darkness.

RLT was first used to help individuals with skin problems and blemishes. Skin that has been injured or is showing symptoms of ageing might benefit greatly from red light treatment.

Light wavelengths are beneficial to skincare in a variety of ways. This treatment can decrease wrinkles, enhance skin health, and help patients’ bodies rebuild collagen. The light stimulates tissue regeneration in the same manner as it does with chronic illnesses,  helping it reduce wrinkles and fine lines due to the increased collagen production

Red Light Therapy may be the finest treatment choice for people with dermatological issues or who just want to try a new technique of skincare which is great because scars are less visible as a result of this treatment. It has also shown results with improved muscle recovery time and blood circulation by repairing sun-damaged skin.
