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

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.

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.

Far Infrared Rays have nothing to do with either ultraviolet radiation (which gives you sunburn and damages your skin) or atomic radiation (the kind from a nuclear bomb.) Far Infrared Radiation is simply a form of energy that heats objects directly through a process called conversion, without having to heat the air in between. Our sun is the principal source of radiant energy that we enjoy daily (some more so than others).

Therapy, in medical term, means the act of remediation of a health problem, after the diagnosis. Far Infrared Therapy is a type of low energy therapy using light in the far infrared spectrum for the treatment of a health problem. Far Infrared Therapy is also sometimes abbreviated to FIR Therapy or Infrared Therapy for short. The light we see every day is actually a combination of many different types. All light is electro-magnetic waves. The wavelength of light determines its properties.

No, while it's true the sun's rays should be used judiciously, especially by fair-skinned people, the fact remains that infrared radiation is safe and promotes vital health. It is the harmful ultraviolet light that Sunscreen lotions block. There are many harmful rays given off by the sun but Far Infrared Rays are not among them. The energy is absolutely essential and beneficial for human beings and all living things in the world.

Hyperthermia, from the Greek words "hyper", meaning high, and "thermos", meaning temperature, can simply be defined as the elevation of the body temperature. In humans a fever is a physiological thermic resource. Hyperthermia represents a natural immune approach in combating disease since it involves inducing an exaggerated version of the body's own fever state. Most illnesses are accompanied by a fever.

Far-infrared radiant (FIR) heat is a form of naturally occurring energy that heats objects by direct light conversion (DLC). DLC warms only the object and does not raise the temperature of the surrounding free air. All life requires FIR heat from the sun. FIR heat is not ultraviolet radiation but a narrow band of energy within the 5.6 to 15 micron level. This type of energy travels only 2-3" deep into the body to increase circulation and nourish damaged tissue.

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.

Of course, the Sun is our primary source of Infrared heat. Have you ever been outside on a partly cloudy spring day of about 50 degrees F. and felt quite comfortable until the sun was suddenly obscured by a cloud? Although the air temperature had not had time to drop, you felt chilled, as the cloud would not let the warming infrared rays through to reach you. Infrared light is an important energy force that promotes healing - a rising of the white blood cell count.

Infrared energy is not only safe, but highly beneficial for our bodies. Far Infrared lamps actively used for medical treatments by doctors, Chiropractors, Acupuncturists, physical therapists, massage therapists for: arthritis, joints pain, stiff muscles, injuries to tendons and ligaments to promoting faster self body healing effect. Infrared heat is radiant heat.

The answers I’ve heard to this particular question over the years appear to be all over the map! Everything from a few centimeters to 4 ? inches. I think the bottom line is really that far infrared penetrates deep within the living tissues of your body. If you want the numbers then I think these are the most accurate to date; 1.5 to 2.8 inches (approx. 3.75 - 7 cm).

Far Infrared Rays (FIR) are energy rays from the Sun. FIR rays are part of the part Electromagnetic Spectrum with a wavelength longer than visible light, but shorter than microwave radiation. The name Far Infrared means "below red" (from the Latin infra, "below"), red being the color of visible light of longest wavelength. Far Infrared electromagnetic radiation has the longest wavelengths in the infrared region, between approximately 50 and 1,000 micrometers.
