Red Light Therapy

Red light is primarily absorbed by the surface layers of the skin and hair, where it may help support skin vitality and promote a healthy, youthful appearance. Near-infrared (NIR) light, by contrast, penetrates deeper into subcutaneous tissues, reaching muscles, joints, and other deeper structures. This deeper light exposure is believed to help support natural cellular energy production and encourage overall wellness by promoting relaxation, recovery, and healthy tissue function.

Yes, eye protection is recommended, especially when facing the light directly. BlockBlueLight's devices are very bright, and the provided safety goggles should be worn to protect your eyes from the intense light. While modest amounts of red and NIR LED light may benefit certain eye conditions, it is important not to stare directly into the LEDs.

LEDs emitting near-infrared light appear off because this light is invisible to the human eye. Although you may not see the light, the LEDs are functioning and delivering therapeutic energy as designed. Near-infrared light (800-900nm) is just beyond the visible spectrum (400-700nm), so you might see a faint pinkish hue or a small pink dot, indicating that the LEDs are working properly and providing effective treatment.

Infrared saunas emit a different spectrum of wavelengths primarily focused on generating heat. They use mid and far-infrared wavelengths (IR-B and IR-C), which primarily heat the skin's surface and the top layer of the skin. In contrast, red light therapy devices emit red and near-infrared wavelengths (IR-A) with high concentration, which penetrate deeper into the subcutaneous tissue and enhance mitochondrial function. This results in improved energy production within cells, promoting overall vitality without significant heat generation.

While natural sunlight offers benefits, it's not always practical to spend sufficient time in the sun, especially with clothing limitations and unpredictable weather. Red light therapy provides a concentrated form of beneficial wavelengths that can be easily integrated into your daily routine at home. It delivers consistent and targeted light exposure, ensuring therapeutic benefits without the variability of sunlight. Additionally, red light therapy can be used regardless of weather conditions or seasonal changes, offering a reliable and convenient alternative to sun exposure.

Red light therapy can be utilized at any time during the day. Many users find morning sessions beneficial as it can help energize and prepare them for the day. Additionally, red light therapy can be used before or after workouts to enhance performance and aid in recovery. The flexibility of red light therapy allows you to incorporate it into your routine at a time that best suits your schedule and needs.

For effective red light therapy, position yourself 15 to 50 cm away from the light source. The duration of each session should be between 10 to 20 minutes. The closer the light source is to your body, the more intense the irradiation power, which can shorten the required treatment time. Conversely, increasing the distance will reduce the irradiation power but cover a larger area, necessitating longer sessions. Adjust the distance based on the area being treated and your individual response to the therapy.

Yes, it is possible to overdose on light. Red light therapy follows a biphasic dose-response, where too little light has minimal effect, the optimal dose provides maximum benefits, and excessive light diminishes the positive effects. To avoid overdosing, adhere to the recommended guidelines: position yourself 15 to 50 cm from the light for 10 to 20 minutes per area. Monitor your individual response and adjust the distance or session duration as needed. Everyone's sensitivity to light varies, so it's important to find the balance that works best for you.
