Infrared radiation, an undetectable form of electromagnetic radiation, is classified into near-infrared and far-infrared, with applications ranging from electronic devices to therapeutic uses. It is particularly beneficial in physiotherapy for pain relief, muscle relaxation, and enhancing circulation while posing risks such as burns and skin irritation. Research indicates that infrared therapy is a safe and effective method for managing pain without medications.

2. What are infrared rays?
 Infrared radiation (IR), sometimes known as infrared light, is
electromagnetic radiation (EMR) with wavelengths longer than those
of visible light.
 It is undetectable by the human eye, although IR have wavelengths
up to 1050 nanometers

3. Sources and Characteristics
 Infrared radiations is also referred to as heat or thermal waves
or electromagnetic waves. This is because they have a heat-inducing
property.
 Sometimes infrared rays are classified as near-infrared and far-
infrared.
 Near-infrared rays are used in electronic applications like TV remote
sensors and photography. Their applications can be similar to visible
light applications since their wavelength ranges are close.
 Far infrared rays are more thermal. Anything generating heat gives
out far-infrared radiation.
 All heated bodies such as heated iron balls, flame, fire etc. are the
sources of infrared radiations. Sun is also a source of infrared
radiation.

5. Instrument used for Therapy
Infrared lamp

6. Therapeutic Uses
 Infrared rays are used for warming the skin and for relaxing the muscles.
Infrared rays are preferred because of their penetration quality through the
skin.
 Infrared radiation finds application as a heating source. There are infrared
saunas used to treat high blood pressure and rheumatoid arthritis. Infrared
radiation is considered to be one of the safest methods of physiotherapy.

7.  Infrared rays penetrate deep into tissues ,
generating heat , promoting tissue repair , relive
muscle tension , improve circulation , and
accelerate healing.
 Hence infrared rays can be used for the following
purposes :
 Pain relief
 decreases muscle spasm
 increases the sensory nerve conduction velocity,
increase in endorphins influencing the pain gate
mechanism
 acceleration of healing and tissue repair-
pressure sores
 used prior to electrical stimulation/testing or
biofeedback to make the skin a better conductor

8. Indications and Contra-indications
 Osteoarthritis
 Rheumatoid arthritis
 Ankylosing spondylitis
 Capsulitis
 Psoriasis
 Joint stiffness
 Odema
 Pain
 Muscle spasm
 eczema
 Tumors
 Tuberculosis
 Photosensitivity
 Mental retardation
 Metal implant

9. Dangers of Infrared Therapy
 Burns
 Skin irritation
 Eye damage
 Dehydration
 Low BP
 Electric shock
 Headache
 Defective arterial blood flow

10. Summary
Infrared promotes a wide range of therapeutic benefits in cells or
tissues. It helps to reduce pain and can be used to treat various
conditions. Research suggests it is a safe, effective to manage pain
without medication.
