Lamp of Infrared Therapy in Physiotherapy

Infrared Therapy in Physiotherapy, also known as infrared radiation (IR) therapy, uses infrared light to provide heat to the body. This therapy is based on the principle that infrared rays pierce the skin and warm the underlying tissues, resulting in various health benefits. Infrared therapy is commonly used for pain relief, as it can help to increase blood flow and promote healing in the affected area. It has also effectively reduced inflammation and stiffness, improved joint mobility, and reduced muscle spasms.

Infrared Therapy in Physiotherapy used in various settings, including hospitals, clinics, and spas. It can be administered through multiple methods, such as using infrared lamps, saunas, or mats. Infrared lamps emit IR radiation, which is absorbed by the body and produces heat, while infrared saunas and mats use heat to create a similar effect. Infrared (IR) rays are electromagnetic radiation with longer wavelengths than visible light but shorter wavelengths than radio waves. They are commonly found in nature and are emitted by warm objects, such as the sun, fire, and animals, including humans.

Categories of Infrared Therapy in Physiotherapy

Infrared Therapy in Physiotherapy can be categorized into three main types:

  • Near-infrared (NIR),
  • Mid-infrared (MIR), and
  • Far-infrared (FIR).

Each class has a different wavelength and is used for various purposes.

Near-infrared (NIR)

NIR has a wavelength range of 0.75 to 1.4 microns and is used in various applications such as remote controls, security systems, and medical imaging.

Mid-infrared (MIR)

MIR has a wavelength range of 1.4 to 30 microns and is used in thermal imaging, spectroscopy, and industrial process control applications.

Mid-infrared (MIR)

Mechanism of Infrared Therapy

Infrared Therapy in Physiotherapy
  • Infrared radiation therapy delivers heat to the body’s tissues using infrared radiation. IR has radiations that are invisible to the human eye but is felt as heat.
  • When infrared radiation penetrates the body’s tissues, it is absorbed by the molecules in the tissues, which causes them to vibrate. This vibration produces heat, which can help to increase blood flow and promote healing in the affected area.
  • The heat from infrared radiation therapy can also help to relax the muscles and reduce pain and stiffness. This is because the heat causes the blood vessels to dilate, which allows more oxygen and nutrients to reach the muscles and other tissues.
  • Infrared radiation therapy can also help to reduce inflammation by increasing circulation and removing waste products from the affected area. Inflammation is a common cause of pain and discomfort in many conditions, so reducing inflammation can help to alleviate these symptoms.
  • Infrared radiation therapy increases blood flow, promotes healing, reduces inflammation, and relaxes muscles. It can be a useful treatment option for various conditions, including arthritis, back pain, and sports injuries.

Infrared radiation therapy can be effective in overcoming pain in a few different ways:
1.   Increases blood flow: The heat generated by infrared radiation therapy causes the blood vessels to dilate, which increases blood flow to the affected area. It provides more blood and oxygen to the tissues, which can help promote healing and reduce pain.
2.   Promotes relaxation: The heat generated by infrared radiation therapy can help relax the muscles in the affected area, reducing pain and stiffness. This can be particularly helpful in chronic low back pain, where muscle tension and spasms can contribute to pain.
3.   Reduces inflammation: Inflammation is a common cause of pain in many conditions, and infrared radiation removes inflammation and waste products from the affected area.
4.   Stimulates endorphin release: Infrared radiation therapy stimulates endorphin release. This can help to reduce pain and promote feelings of well-being.





Infrared radiation therapy can also help reduce inflammation, a common cause of pain. The heat from the treatment can help to increase circulation, which can help to deliver oxygen and nutrients to the affected area and remove waste products that may be contributing to inflammation.
Studies have shown that infrared radiation therapy can effectively reduce pain in rheumatoid arthritis, fibromyalgia, and chronic low back pain. Infrared radiation therapy may vary depending on the specific condition and the individual.
It’s also important to consult a healthcare professional before beginning any new pain treatment. Infrared radiation therapy should not substitute medical care and pain management.





















Infrared radiation therapy can effectively reduce back pain, particularly chronic low back pain. LBP is due to various factors, including muscle strain, herniated discs, and spinal stenosis.
Infrared radiation therapy works by increasing blood flow and promoting the relaxation of the muscles, which can reduce pain and stiffness. The heat from the treatment penetrates deep into the tissues, which can help to decrease inflammation and improves healing.
Studies have shown that infrared radiation therapy can effectively reduce pain and improve function in people with chronic low back pain. In one study, participants who received infrared radiation therapy reported significant reductions in pain intensity and improvements in physical function compared to those who received a placebo treatment.




















Infrared radiation therapy can be helpful in reducing muscle spasms. Muscle spasms are caused by the contraction of a muscle or group of muscles, which can be painful and limit the range of motion. Infrared radiation therapy can help relax the muscles, reduce inflammation, and increase blood flow to the affected area, relieving muscle spasms.
The heat from infrared radiation helps to increase the temperature of the muscles, which can increase blood flow and relax the muscle fibers. This increased blood flow can help deliver nutrients and oxygen to the affected area, aiding the healing process. Additionally, the heat from infrared radiation can help to reduce pain and stiffness, which can help to reduce muscle spasms.
