Light therapy for tennis elbow
Tennis elbow, also known as lateral epicondylitis, is a painful condition that occurs as a result of overuse of the tendons in the elbow. It is especially common in people who perform repetitive movements with their arm and wrist – such as tennis players, craftsmen and office workers. Fortunately, there is an effective and natural form of treatment without side effects: light therapy with red light therapy and infrared light therapy.
Here at Heat Sense, we offer specialized light therapy units for home use that can help relieve pain, reduce inflammation and promote healing – all without the use of medication or surgery.
What is tennis elbow?
Tennis elbow is caused by small tears in the tendons that attach to the outside of the elbow. The symptoms may include:
- Pain in the elbow, which often radiates down the forearm
- Weakness in grip
- Tenderness when you press on the outside of the elbow
- Discomfort with lifting or repetitive wrist movements
The condition can last for months if not treated correctly, and many experience recurring episodes. Therefore, it is important to find a treatment that both relieves the pain and promotes healing.
How does light therapy work for tennis elbow?
Light therapy, also called photobiomodulation, works by using specific wavelengths of red and infrared light to stimulate the body’s natural healing processes. The light penetrates deep into the tissue and activates the cells’ energy production, reduces inflammation and increases blood circulation.
In the case of tennis elbow, light therapy can:
- Reduce inflammation in the tendons
- Increase blood flow to the affected area
- Accelerate tissue repair
- Relieve pain without side effects
This makes light therapy an attractive alternative or supplement to physiotherapy, painkillers and cortisone injections.
Red and infrared light therapy – what is the difference?
Light therapy often uses two types of light:
- Red light with a wavelength of approx. 630-660 nm. It works on the skin and superficial tissue
- Infrared light with a wavelength of approx. 850-940 nm. It penetrates deeper into muscles and joints. See also laser therapy for muscles
Red light is ideal for treating superficial inflammation and tenderness, while infrared light is particularly effective for deeper tissue problems – such as tendons and joints in tennis elbow.
Here on the shop you will find products that combine both types of light for maximum effect.
