Red & near-infrared light
Red light devices are based on a variety of technological components that work together to achieve the best possible therapeutic effect. Here are the most important aspects that make up the technology behind a red light device.
The effectiveness of a red light device depends heavily on the wavelengths used. Red and near-infrared (NIR) light are the most commonly used wavelengths because they penetrate deep into the skin and tissue. Red light is typically in the range of 620-750 nanometers, while NIR light is in the range of 750-1200 nanometers. However, that does not mean that all of these wavelengths are actually useful. Research has shown that wavelengths between 630nm and 680nm, as well as 800nm to 880nm, are the most effective. These specific wavelengths were chosen because they effectively support cell functions and promote healing.
Irradiance measures the power of light hitting a specific area and is measured in milliwatts per square centimeter (mW/cm²). Higher irradiance means that more energy penetrates the cells, which enhances the therapeutic effect. A good red light device should provide uniform and sufficiently high irradiance to achieve the desired health benefits. It is recommended to choose a device that provides at least 30 mW/cm² and, ideally, approximately 100 mW/cm² (at a close irradiation distance of approximately 15 cm).
The use of electrical devices can generate electromagnetic fields (EMFs) that may be potentially harmful to health. High-quality red light devices are designed to minimize EMF emissions and ensure that the therapy remains free of unwanted electromagnetic influences. It is important to choose devices that guarantee low EMF levels.
The correct dosage is crucial for the effectiveness of red light therapy. The dosage refers to the amount of light energy transferred to the body and depends on the irradiance and duration of treatment. Too much or too little light can compromise the desired results. Therefore, it is important to follow the recommended treatment times and intensities to achieve the best results.
Der Strahlwinkel bestimmt, wie breit das Licht des Geräts verteilt wird. Ein breiterer Strahlwinkel ermöglicht es, größere Bereiche des Körpers gleichzeitig zu behandeln, während ein schmalerer Strahlwinkel eine intensivere und fokussiertere Behandlung ermöglicht. Die Wahl des richtigen Strahlwinkels hängt von den spezifischen therapeutischen Bedürfnissen und den zu behandelnden Körperbereichen ab.
There is some debate as to whether pulsating light is beneficial in red light therapy. Some manufacturers claim that pulsed light can enhance cell stimulation and therapeutic effects. However, recent research has shown that continuous light is just as effective, if not more so. Pulsed light offers no significant advantages over continuous light, and the additional technical requirements often make it unnecessarily complicated and more expensive without offering any additional benefits.
Using a red light panel as ambient lighting can offer several health benefits, such as regulating the circadian rhythm, improving mood and relaxation, and reducing eye strain. Red light supports a healthy sleep cycle by not suppressing melatonin production, unlike blue light. It creates a calming environment that helps reduce stress and promote relaxation. In addition, red light is easier on the eyes and reduces strain, making it an ideal lighting option for evening activities. Properly integrating red light into your lighting design can create a comfortable and health-promoting environment.
