What is Red Light Therapy?
Learn about red light therapy, the science, how it works in the cell, and more.
Hey there! Curious about what red light therapy is all about? Just as humans need nutrients from foods for proper cell function, we now know specific wavelengths of light affect our moods, enhance physical performance, power up our cells, affect our hormones, improve sleep, increase recovery, and positively affect our gene expressions. The human body actually needs light to function and be its healthiest self.
With that in mind, get ready to dive into the world of red light therapy devices, a non-invasive treatment using and safe light technology that's gaining popularity faster than a cat chasing a laser pointer!
Red light therapy, also known as LLLT therapy (low-laser light therapy), operates by utilizing specific wavelengths of red and near-infrared light to interact with cells in the body. And no, we're not talking about disco lights here (although that would be pretty groovy). We're referring to the latest LED lamp technology, which utilizes specific wavelengths of light.
This light therapy has found its way into both the medical and aesthetic fields, making it a hot topic in the world of skin rejuvenation treatments and much more. Numerous studies have been conducted to explore the effectiveness of low-level laser therapy treatments.
How Does Red Light Therapy Work?
Red light therapy is a treatment method that exposes the body to red or near-infrared light, which can improve skin feeling, skin complexion, and stimulate collagen production. This type of light is not visible to the naked eye but can penetrate deep into the skin, improving complexion. Red and near-infrared light has numerous physiological and biochemical mechanisms that occur at a cellular level. To keep things simple, let’s discuss the two central mechanisms and how they benefit cellular health.
Mitochondria stimulation and energy production
These wavelengths are able to penetrate the cells and activate the mitochondria, generating an increase in cellular energy production. This is exciting because healthy mitochondria are vital to our health, disease prevention, energy, and anti-aging. When red and near-infrared light shines on the body, it stimulates the mitochondria and produces ATP (adenosine tri-phosphate). ATP is the fuel the body uses to perform every function, from breathing to thinking and even pumping your heart. Think of the mitochondria in the cells as tiny little batteries that power up all body functions and physical activity. Without red and near-infrared light, the function of our mitochondria deteriorates due to the lack of cytochrome c oxidase’s ability to bind to oxygen to produce cellular energy (ATP) efficiently.
Hormesis
Hormesis is the process by which a transient metabolic stressor stimulates adaptations that actually improve health. An example would be exercise; it creates metabolic stress and temporarily increases reactive oxygen or free radicals. In response, your body adapts to it by improving cardiovascular health, blood flow and strengthening and growing mitochondria. Red and near-infrared light activates the same cell defense as exercise by activating a low-level inflammatory response to switch on the Antioxidant Response Element (A.R.E). A.R.E. is the body's internal cellular antioxidant defense system that puts the fire out on inflammation and free radicals. Turns out the body needs red and near-infrared light to create these low-level stressors to improve overall cellular health.
Stimulates cellular function and promotes healing
One of the key benefits of red light therapy is its ability to stimulate collagen production, improving skin complexion and feeling. LLLT therapy is an effective method for achieving these results. When cells are exposed to red or near-infrared light, it enhances their energy production and metabolism, improving the skin complexion and collagen synthesis.
Additionally, this light therapy can leave the skin feeling rejuvenated and youthful. ELT (Energy Light Therapy) is a popular treatment that utilizes red and near-infrared light to stimulate cellular activity and promote skin health. This can lead to improved collagen production, reduced inflammation, and accelerated healing processes. The study shows that collagen helps in repairing tissues, resulting in a better skin feeling and complexion.
Utilizes specific wavelengths to target different tissues
Red light therapy utilizes specific wavelengths of light that are known to have therapeutic effects on different tissues in the body, including the skin feeling and collagen production. This therapy is often used by professionals for its numerous benefits. Specifically, most research shows the narrow ranges of 630-680nm and 800-880nm to be the most beneficial. For example, red light with a wavelength of around 660 nanometers is often used to treat superficial skin conditions and promote collagen production. On the other hand, near-infrared light with a wavelength of around 850 nanometers can penetrate deeper into tissues like muscles and joints, providing therapeutic benefits.
Explain the Science Behind Red Light Therapy
Photobiomodulation triggers biochemical reactions in cells.
The science behind it is fascinating. This innovative treatment involves using specific wavelengths of LED light to stimulate cellular activity in our bodies, resulting in a rejuvenated skin feeling. The laser light targets collagen production, promoting the natural regeneration process. In a recent study, volunteers experienced improved skin after undergoing LED treatments. Through a process called photobiomodulation, these light waves trigger biochemical reactions within our cells.
Absorption of light energy by mitochondria enhances cellular metabolism.
The key players in this process are the mitochondria, which are often referred to as the "powerhouses" of our cells. These light sources are essential for the functioning of our cells and are responsible for generating energy. They work in groups to ensure that our cells have enough energy to carry out their various functions. Researchers have studied these light sources and their role in cell function for years. Through their research, they have gained a deeper understanding of how light technology plays a crucial role in maintaining cellular health and overall well-being. When exposed to red and near-infrared light wavelengths, the skin's tiny organelles absorb the energy from the photons. These organelles are found in various groups within the skin. Volunteers can participate in experiments to study the effects of red and near-infrared light on the skin's organelles. This absorption enhances cellular metabolism and activates various signaling pathways within the cell, utilizing light technology and light sources. The skin benefits from this process, which is known as elt.
Increases production of ATP, leading to improved cell function.
One of the significant outcomes of this enhanced cellular activity is an increase in adenosine triphosphate (ATP) production, thanks to the use of light technology and light sources. This was observed in the skin of the volunteers. ATP is a molecule that provides energy for many essential functions within our cells. It is crucial for the functioning of various light sources in our body, including groups of cells that rely on light technology. Additionally, ATP plays a role in maintaining the health and vitality of our skin. With the use of light technology, cells can carry out their tasks more efficiently and effectively. This is because light sources provide the necessary ATP for cells to function optimally. In particular, the use of ELT (electroluminescent technology) has shown promising results in enhancing cellular activities. By incorporating ELT into cellular processes, groups of cells can work together more effectively, thanks to the increased availability of ATP.
Red light therapy has been shown to have numerous benefits for the skin and cellular function. The therapy uses ELT to target specific groups of cells and improve their overall function. ELT has been used for wound healing, reducing inflammation, relieving pain, improving skin health, and even promoting hair growth. ELT is beneficial for various groups and can be used with different light sources. While some experts debate the effectiveness of ELT on skin and consider it a placebo effect, many studies support its positive effects on various conditions caused by light sources.
