You must have heard of red light and near infrared light, which are many health benefits for our body. It is a safe, natural and non-invasive light therapy method. There are thousands of user-reviews studies about the health benefits of Red Light and near infrared light Therapy.

Differences Between Red light and Near Infrared Light

As they have different wavelengths, these two forms of light therapy affect the health of body at different depths:

1.Red Light Health Benefits: Unlike Ultraviolent (UV) light, red light is visible and occupies what’s known as the ‘long end’ of the visible spectrum with wavelengths of 630nm-700nm penetration into the skin. Affects the function of the mitochondria, which are the powerhouse of your cells.

2.Near Infrared Light Health Benefits(NIR）: Sits right next to red on the electromagnetic light spectrum. It is invisible and penetrates further than red light; it enters the skin but also goes another 1.5 inches into the body at around 800nm to 1 millimeter of penetration. Like red light, acts on the mitochondria of your cells and helps to increase cellular energy production.

Red and near infrared light (NIR) has spectacular healing powers. Its health benefits and many applications are one of the biggest health discoveries of recent decades. These findings led to hundreds of more studies showing the health benefits of light therapy using this wavelength.

Red Light and Near Infrared Light Health Benefits

We all know that red light and infrared light can impact our health from a sunburn sustained after staying too long on the beach. What you may not know is that light actually enters human cells. Some colors of the light spectrum omit different energy frequencies which impact more than your skin and can alter everything from the immune system, energy, brain activity, to blood pressure.

Ever since the initial experiments in space, there have been hundreds of clinical studies and thousands of laboratory studies conducted to determine if red light and infrared light has medical health benefits. Many studies have had promising results, at the moment.

Red and near infrared light therapy is clinically proven to:

Red light and Near Infrared Light Therapy Case Study 

Dental pain. In another small study, people with temporomandibular dysfunction syndrome (TMD) had less pain, clicking, and jaw tenderness after red light therapy.

Hair loss. One study found that men and women with androgenetic alopecia (a genetic disorder that causes hair loss) who used an at-home RLT device for 24 weeks grew thicker hair. People in the study who used a fake RLT device didn’t get the same results.

Osteoarthritis. One study found red and infrared light therapy cut osteoarthritis-related pain by more than 50%.

Tendinitis. A very small study of 7 people suggests RLT lessens inflammation and pain in people with Achilles tendinitis.

Wrinkles and other signs of skin aging and skin damage. Research shows RLT may smooth your skin and help with wrinkles. RLT also helps with acne scars, burns, and signs of UV sun damage.

How Does Red Light and Near Infrared Therapy Work ?

With red light and near infrared light therapy, you expose your skin to a red light therapy panel, near infrared light therapy device . A part of your cells called mitochondria, sometimes called the “power generators” of your cells, soak it up and make more energy. Some experts think this helps cells repair themselves and become healthier. This spurs healing in skin and muscle tissue.Therefore, we can get many health benefits from red light and near infrared light.
