Infrared light can play the following roles for women: First, it can accelerate local blood circulation. For women, this physiotherapy instrument has a stronger effect on accelerating blood circulation. Because most women have relatively slow blood circulation. Once the local area is stimulated by factors such as cold or trauma, it may slow down the blood circulation. Taking such physical therapy at this time can effectively promote the recovery of related diseases. Second, it can effectively keep warm. Some women are affected by trauma or other pathological factors, which will lead to obvious symptoms of chills and purple at the distal end of their limbs. Physical therapy can effectively keep their limbs warm. Third, it can play an anti-inflammatory role. Through this infrared physiotherapy, it has obvious anti-inflammatory effect on local lesions, and then relieves local pain. Fourth, it can reduce swelling. When some female patients have trauma or inflammation, their limbs will swell more obviously than men. Such women will suffer from persistent swelling due to such diseases, and these symptoms can be effectively alleviated through such physical therapy.
