Guillain-Barré syndrome is an acute or chronic neurological disorder that mainly affects peripheral nerves and may cause symptoms such as muscle weakness and paresthesias. Methods typically include medications, physics, and more. Spring sunlight is rich in ultraviolet and infrared rays, which have a variety of benefits for the human body. Ultraviolet rays can promote the body's synthesis of vitamin D, which aids in the absorption and utilization of calcium, thereby enhancing bone health. Infrared rays penetrate deep into the body's tissues to promote blood circulation and metabolism, helping to relieve pain and muscle fatigue. 
For patients with Guillain-Barré syndrome, ultraviolet and infrared rays in sunlight may bring the following benefits: 1. Promote blood circulation: Infrared rays in sunlight can dilate blood vessels, improve blood circulation, and help reduce inflammation and edema of peripheral nerves. 2. Pain relief: The infrared rays in the sunlight can penetrate deep into the human tissues, relieve pain and muscle fatigue, and help improve the symptoms of patients. 3. Improve immunity: Proper sun exposure can improve the body's immunity, help resist the invasion of viruses and bacteria, and prevent infection.

As an adjunct, the drug "sun exposure" can help patients recover, but for Guillain-Barré syndrome, the drug is always the most important. Traditional Chinese medicine (TCM) is a traditional medicine technique, and Dr. Zhang Kexin has summarized the experience of patients with Guillain-Barré syndrome in the past 40 years, and proposed a pure Chinese medicine method "Yufang Shengji Decoction".
