Red light therapy for the lower leg – Heat Sense

Red and infrared light therapy for the lower leg – effective treatment for the calf and Achilles tendon

Do you have Achilles tendon pain or tightness in your calf? This lower-leg light therapy device is designed to cover the entire strained area—from the calf muscle down over the Achilles tendon to the heel and the back of the foot. A targeted solution for you if you want natural pain relief and support for the body’s own healing process.

The product uses red and infrared light therapy, which penetrates the tissue and stimulates the cells’ energy production (ATP). It increases blood circulation, improves oxygen delivery, and supports repair of tendon and muscle tissue. The treatment is gentle, documented, and completely drug-free.

Suitable for, among other things:

  • Achilles tendon pain (Achilles tendinitis)

  • Calf muscle overuse
  • Minor inflammation in tendons and connective tissue

  • Soreness after running and sports

  • Stiffness in the lower leg and hindfoot

Achilles tendon pain is often linked to tight calf muscles. Treating the entire area together provides a more holistic effect than focusing only on the pain point itself.

Specifications

The device uses both 660 nm red light and 850 nm infrared light to deliver an effective, deep-acting treatment. The red light works mainly in the upper layers of the skin and superficial muscles, while the infrared light penetrates further and affects deeper muscle tissue, joints, and connective tissue. The combination helps improve blood circulation, reduce inflammation, and support the body’s natural ability to recover and heal.

  • Light intensity: approx. 120 mW/cm²
  • 164 LED diodes with both 660 nm red light and 850 nm infrared light.
  • Settings: Continuous light or pulsed light
  • Auto shut-off: Can be set to switch off automatically after 5, 10, 15, 20, 25, or 30 minutes

Optimal coverage and close contact

The light therapy device is designed to wrap around the back of the lower leg, so both the calf and Achilles tendon are treated at the same time. The flexible fit ensures good contact with the skin, which is essential to achieve maximum effect from red and infrared light therapy.

Easy to use:
Place the device around the lower leg, select a program, and let it work for 15–30 minutes. You can sit back and relax during the treatment—for example, while reading, working, or watching TV.

For chronic issues or long-term overuse, regular use is recommended for the best effect.
