Infrared light from the sun is experienced on the earth in the form of heat. Quality sunglasses protect your eyes from the fatiguing and drying effects of infrared radiation.

YES, using infrared LED photo rejuvenation lights according to directions will help normalize dry skin.

The primary goals of JWST are to study galaxy, star and planet formation in the Universe. To see the very first stars and galaxies form in the early Universe, we have to look deep into space to look back in time (because it takes light time to travel from there to here, the farther out we look, the further we look back in time). The Universe is expanding, and therefore the farther we look, the faster objects are moving away from us, creating redshift.

Infrared is one of the many forms of light on the electromagnetic spectrum that are not visible to the human eye. The electromagnetic spectrum includes gamma rays, X-rays, ultraviolet, visible, infrared, microwaves, and radio waves. Infrared light waves are longer than visible light waves, and shorter than microwaves. An independent study was conducted in August 2000 by the United States Department of Health and Human Services regarding the safety of infrared light.

Far infrared light is the beneficial part of the sun’s spectrum that is invisible to the human eye and felt as heat.

I have rosacea and VERY sensitive skin. I found that the DPL System is so powerful that I needed to reduce my treatments to 4-5 minutes to prevent a flare-up. I also found it helps to apply a damp cloth to my skin after each treatment. And be sure to start with clean skin...lotions could heat up and cause a problem.

YES, I have seen reports of hyper-pigmentation and scars fading over time from the use of these lights.

I have read reports of accelerated hair growth and stimulation of dormant hair follicles with the use of infrared LED light.

It is safer than natural sunlight. Our infrared light and heat has all the benefits of sunlight without the danger of ultra-violet rays. Our infrared light penetrates almost 2” into the body faster then conventional saunas thus implementing health benefits quicker and more beneficially.

Because infrared light has no ultra-violet rays, it is actually as beneficial, but much safer than natural sunlight. It is also more effective than steam because the infrared light penetrates the body so quickly and safely.

A little, in much the same way as modern camcorders. The CCD is sensitive to infrared, but it has a filter in place that does a pretty good job of masking it. While the camera will show bright direct infrared sources (like LEDs) as bright white, IR lighting doesn't work very well as scene illumination.

Much like Bluetooth Infrared (IR) wireless data transmission is also employed in short-range communication among personal digital assistants (PDAs), mobile phones, FAPtops, PCs and printers. Its main differentiation from Bluetooth is that IR is a line sight communications technology, meaning that the two device IR transceivers must have plain line of sight in order to communicate.

Yes and no. Outdoor models are designed for well ventilated places. Well ventilated does not mean you have a bit of a draft under a crack in the door. In a garage with a window or garage door open, yes you can safely use any of the 12-IR -> 24-IR range of heaters The DESA range of infra-red heaters is the way to go for indoor infra-red heat. These units are designed for indoor use and have safety mechanisms built in to protect you.

Infrared rays are located just past the red portion of the visible light spectrum. While some experts believe that infrared light can be harmful in certain situations (such as being near large bodies of water or at high altitudes), most feel that the sun's infrared rays do not pose a danger to the eyes.

Far infrared is a vital source of “light” energy that you're probably not getting enough of. It’s part of the electromagnetic spectrum of sunlight that’s safe and extremely beneficial to your health. If you want the scientific explanation, then click here.

Infrared radiation is one of the many types of 'light' that comprise the electromagnetic spectrum . Infrared light is characterized by wavelengths that are longer than visible light (400-700 nanometers, or 0.4-0.7 micrometers; also denoted as microns). Astronomers generally divide the infrared portion of the electromagnetic spectrum into three regions: near-infrared (0.7-5 micrometers), mid-infrared (5-30 micrometers) and far infrared (30-1000 micrometers).
