What is infrared therapy?
Infrared light is one of several innovative therapies that are being trialed for the management of patients with acute or chronic pain. The therapy uses certain wavelengths of light that are delivered to sites of the body that have injuries.
Unlike ultraviolet light - which has damaging effects upon the tissues and cells of the body - infrared light helps cells regenerate or repair themselves. Infrared light also improves the circulation of oxygen-rich blood in the body, promoting faster healing of deep tissues and relieving pain.
One of the characteristics of infrared light is its ability to penetrate below the skin layers, providing a much greater depth which is able to effectively provide pain relief. In fact, this invasive, natural, and painless method can provide a vast range of health benefits, without damaging the skin through UV radiation
Infrared light is the heat people feel when exposed to the sun. The skin naturally radiates infrared heat every day. Infrared light has shown immense health benefits, from pain relief to reducing inflammation.
How does infrared therapy work?
Infrared light penetrates to the inner layers of the skin at about 2 to 7 centimeters deep. Hence, it reaches the muscles, nerves and even the bones. Many studies have shown that a frequency of infrared light, with wavelengths from 700 to 1,000 nanometers, is best used for healing inflammatory conditions.
The use of electricity for healing purposes began in 2,750 BC when people used electric eels to give electric shocks. Electricity and magnetism were used in people with just little success. However, in 1975, transcutaneous electrical stimulation (TENS) was developed to treat chronic pain. It was not until recently that infrared therapy was developed to improve wound healing, reduce the pain caused by arthritis, boost endorphin levels, and bioactivate neuromodulators.
Infrared therapy technology allows people to harness the benefits of the sun, without being exposed to harmful ultraviolet rays. Also, infrared therapy is safe and effective, without adverse side effects. As a matter of fact, infrared light is safe and is used even for infants in the neonatal intensive care.
Infrared light is absorbed by the photoreceptors in cells. Once absorbed, the light energy kickstarts a series of metabolic events, triggering several natural processes of the body on a cellular level.
The key to the efficacy of infrared light therapy may be nitric oxide, a gas that is vital to the health of the body’s arteries. Nitric oxide is a potent cell signaling molecule that helps relax the arteries, battles free radicals to reduce oxidative stress, prevents platelet clumping in the vessels, and regulates the blood pressure. Hence, this molecule enhances blood circulation to deliver vital nutrients and oxygen to damaged and injured tissues in the body.
The increase in the blood flow to the different parts of the body makes it possible for oxygen and nutrients to reach the cells, enabling them to function properly and effectively. Hence, this therapy stimulates the regeneration and repair of injured tissues, reducing pain and inflammation.
Infrared light therapy is applied in the treatment of various health conditions, including back pain, arthritis, bursitis, blunt trauma, muscle strain, carpal tunnel syndrome, neck pain, back pain, diabetic neuropathy, rheumatoid arthritis, temporomandibular joint pain (TMJ), tendonitis, wounds, sciatica, and surgical incisions.
Conclusions and perspectives on infrared therapy
Infrared therapy is a safe and effective way to reduce pain and treat a wide array of conditions. It seems to be a safe, effective, and drug-free way for long-lasting pain relief. It also helps to heal injured body parts.
With the treatment of injuries come multiple benefits such as pain relief, reduction of inflammation, and the restoration of the function of the affected body part. Other conditions that can be treated by infrared therapy include joint pain, joint inflammation, muscle pain, spine injuries, nerve pain, and sports injuries.
BENEFITS OF INFRARED THERAPY:
Improves normalising of high blood pressure
Stabilises blood and lymph flow
Helps if you have a fatigue or exhaustion
Helps if you have inflamed ears, nose or throat
Decreases pain with arthritis or rheumatic
Helps if you have a disc hernia
Regeneration of cells
Contraindications: (You should not use Infrared if you have the following conditions)
– Inflammatory illness which leads to decompensation of organs and systems
– Deep Vein Thrombosis and varicose vein areas.
– The thermal effect of I-lamp reduces the excitability of nerve endings
– Improvement of blood circulation
– The regression of oedema
– The chemical and mechanical stimulation of nerve endings
– The thermal effect of infrared rays and the improvement of pain threshold, all of which alleviate the role of pain
The deep penetrating warmth generated from I-lamp is commonly used in medical practice for pain relief.
The result is better blood circulation specifically targeted to the affected muscles.
The metabolism is also stimulated using the lamp and the body’s natural defence system is mobilised, this then helps to support and boost the healing process.
