Quick Answer: How Far Infrared Penetrates The Body Research?

The body experiences this energy as radiant heat, which can penetrate up to 1 1/2 inches beneath the skin. It’s believed that this wavelength of light impacts the bonds between molecules in cells, and in turn, can provide the therapeutic effects supposedly linked to infrared saunas.

How far does far infrared penetrate?

Far infrared waves can penetrate up to three inches deep to generate warmth that can provide immense relief to muscles and internal organs.

How deep does infrared light penetrate the skin?

Low-power infrared light in the milliwatt range does not penetrate a full thickness section of human skin (2mm), nor does it deliver any significant infrared energy to a depth of 3 cm into the brain. High-power infrared light achieved at least 3 cm penetration into the brain.

What is the range of near infrared?

Near-infrared light generally refers to light within the wavenumber range of 12,500 to 4,000 cm1 (wavelengths from 800 to 2,500 nm ) (see Fig.

Can infrared pass through body?

The protein, after absorbing light from the far-red part of the spectrum, shines in the near-infrared, at wavelengths of around 700 nanometers. These longer wavelengths can penetrate mammalian tissue and even pass through bone.

Which is better far infrared or near infrared?

Near infrared units tend to promote topical healing and mild pain relief quite effectively, but far infrared heating units are incredibly effective at removing toxins, improving circulation, and relaxing the muscles.

Can you get too much far infrared?

Dr. Sharma says the dry heat generated in an infrared sauna can cause you to become overheated, and if used for a prolonged session, it can also cause dehydration and even heat exhaustion or heat stroke.

Can infrared penetrate skull?

Researchers have found that high-powered NIR light can penetrate the skull to reach the brain and aid in TBI therapy. Near-infrared light has been shown to penetrate the skull to aid traumatic brain injury patients. “Our data shows no significant amount of light gets to the areas needing to be treated.”

Is far infrared harmful?

There is no danger or harmful effects from coming in contact with FIR energy itself. In fact, it’s the exact opposite. Far infrared rays are super beneficial to the functioning of our bodies. It’s safe, effective and affordable.

Can infrared penetrate clothing?

The near-infrared will penetrate clothing, barely, but each wavelength has a finite level of penetration. So, if it has to go through clothing first, it won’t penetrate as deeply into skin. So, the best bet is to have the red and near-infrared as close to bare skin as possible.

How many nm is far infrared?

Wavelength range and sources Infrared radiation (IR), also known as thermal radiation, is that band in the electromagnetic radiation spectrum with wavelengths above red visible light between 780 nm and 1 mm. IR is categorized as IR-A (780 nm-1.4 µm), IR-B (1.4-3 µm) and IR-C, also known as far-IR (3 µm-1 mm).

Does near-infrared produce heat?

The shorter “near-infrared” waves, which are closer to visible light on the electromagnetic spectrum, don’t emit any detectable heat and are what’s discharged from a TV remote control to change the channels.

What’s the difference between near and far infrared?

“Near infrared” light is closest in wavelength to visible light and ” far infrared” is closer to the microwave region of the electromagnetic spectrum. The longer, far infrared wavelengths are about the size of a pin head and the shorter, near infrared ones are the size of cells, or are microscopic.

How is far infrared generated?

Far Infrared is Safe – Your Body Generates it When our bodies are heated by FIR rays the activity level of our atoms are increased and heat can be generated. Our bodies radiate Far Infrared energy through the skin at 3 to 50 microns, with most output at 9.4 microns.
