A paper co-written by Professor Werner Siems of the German Institute of Physiotherapy and Geriatrics pointed out that infrared therapy is a very effective therapy to relieve back and musculoskeletal pain. However, infrared rays with different wavelengths have different penetrating abilities. Near infrared ray (IR-A DIN) can penetrate deep into subcutaneous tissue, increase local thermal effect and promote blood circulation, while short-wave infrared ray (IR-BDIN) and medium-wave infrared ray (IR-C DIN) can cover a larger irradiation area. The combination of three layers of infrared rays can promote local thermal effect from both depth and breadth. In order to confirm this result, the researchers used Philips infrared therapeutic instrument (generating 45-50% IR-A near infrared rays) to treat patients with degenerative osteoarthritis, low back pain and rheumatoid arthritis, and evaluated whether their pain and limb mobility were effectively improved. 207 patients were divided into infrared light therapy group, ordinary light therapy group and control group. The experimental results show that the pain of patients with degenerative osteoarthritis is obviously relieved (14-22%), and the pain and limb mobility of patients with low back pain are obviously improved (35-40%). After a week of phototherapy, the physical activity of patients with rheumatoid arthritis has also been improved.

Many celebrities say that Philips InfraCare infrared therapeutic instrument helps them to relieve the pain of cervical vertebrae and waist and sports injuries caused by busy work. Yang Jinhua is one of them (article from Sina Entertainment).

"Artist Yang Jinhua embodies the beauty of Shu Huo. In addition to endorsing Philips InfraCare infrared therapeutic lights, she pays great attention to the quality of life outside the play. Although she is very busy at work, she still finds time to exercise. For more and more office workers in Taiwan Province Province, their bodies ache because of long-term incorrect sitting posture. In addition to emphasizing the importance of health, Yang Jinhua also reminded everyone to remember to be good to themselves. "
