What is Infrared Light?

Infrared light is a light energy invisible to the human eyes. However, the light can be felt on the skin as it slowly heats up. The most two common sources of infrared light include the sun and fire. Infrared light represents a vast spectrum of light with wavelengths ranging from 700 nm to 1 mm. Infrared light’s shortest wavelengths are referred to as near-infrared and represent a red spectrum of visible light, while the longest wavelengths are referred to far-infrared and are naked to the human eye. Near-infrared light has attracted a lot of attention from researchers and scientists for its anti-inflammatory properties and the ability to boost healing and other positive cellular effects.

Infrared light has been put under several studies and clinical studies to determine its potential in boosting the health of the human body. From the studies, infrared light was established to have numerous benefits on the human body. Today, infrared light therapy is widely used in medicine, dentistry, and veterinary medicine fields. The therapy has been proven to be a natural and safe alternative method for treating health conditions such as muscle pain, arthritis, and joint pains, among others.

Benefits of Infrared Led Light

1. Boosts cardiovascular health

Infrared light plays a significant role in improving the wellbeing of the cardiovascular system. The light stimulates the production of nitric oxide, which is an essential molecule for ensuring the health of the blood vessels. Nitric acid plays the role of relaxing the arteries and preventing blood clots and clumping in the vessels. The molecule also eliminates free radicals, thus preventing oxidative stress and regulating blood pressure.

2. Treats pain and inflammation

Infrared light therapy has been approved to be a safe and effective treatment for pain and inflammation. Infrared light has the ability to penetrate deep through the skin layers to treat joint pains and inflammation. It plays a significant role in improving blood circulation in the skin and other parts of the body, thus boosting the oxygen and nutrients supply to injured tissues, resulting in healing, easing pain and inflammation, and offering protection against oxidative stress.

3. Treatment of muscle injuries

Like other natural light therapies, infrared light therapy also stimulates the mitochondria within the body cells, which in return triggers the growth and repair of new muscle cells and tissues. This simply means that infrared light can quicken the process of muscle recovery after a muscle injury.

4. Detoxification

Infrared is widely used in saunas for detoxification purposes. Infrared light is used at saunas to raise the body's core temperature, resulting in detoxification at the cellular level by releasing impurities in the form of sweat. Detoxification plays a significant role in strengthening the immune system of the human body through aiding the proper functioning of the biochemical processes in the body.

5. Potential cancer treatment

Studies have shown that infrared light therapy is a potentially viable treatment for cancer. Infrared light wavelengths activate nanoparticles rendering them highly toxic to the surrounding cancer cells. Infrared has a very high potential of becoming an alternative cancer treatment.

Possible side effects of infrared light

Despite infrared light having so many health benefits, it also comes with possible side effects. Some of the side effects include;

1. Skin damage

About 65% of infrared light that gets to the skin penetrates to the dermis before absorption. With over exposure of high infrared temperatures, this could result in inflamed cells (skin damage).

2. Eye damage

Eyes are extremely sensitive to infrared light. The heat from the light can damage vital proteins that ensure the normal functioning of the retina, and the passing of ions and enzymes through the lens, resulting in reduced clarity of eye sight.

3. Current health issues? - always seek a doctors advice before use

Experts warn against the use of infrared light as a replacement treatment plan to chronic diseases. More and more patients are abandoning their doctors recommendation of treatment plans for self-healing. This can be dangerous, as not everything you hear on the internet is factual, or clinically proven. Always seek a doctors advice before starting a light energy treatment.

Differences between red light and infrared light

Most people often don’t differentiate between red LED light and infrared LED light. Perhaps due to the presence of the term red in both of them. However, red light and infrared light are two very different light spectrums. To help distinguish them, here are some differences;


The most distinguishable property between red light and infrared light is in their visibilities. Red light can be seen by the human eye, and can be easily distinguished from blue light or orange light. On the other hand, infrared light is invisible and cannot be seen with the bare human eye. The only way to observe infrared light is by using specialised equipment.


Wavelengths emitted by red light differ greatly with infrared light wavelengths. Red light produces wavelengths that range from 620 nm to 750nm. That is somewhere close to near-infrared light. On the other hand, infrared light represents a vast spectrum of light whose wavelengths range between 700 nm to 1 million nm (1 mm). This explains the heating effects that come with infrared light.

Moving away from the differences, most people are also concerned about the safety of infrared light and whether it can damage the skin. To clear the air, infrared light is safe to use, just avoid eye contact and over use; as you would with any light energy colour. To avoid over use of infrared led make sure to follow your product instructions, as overly exposing your skin to extreme infrared temperature can result in inflamed cells.
