Soaking in hot water can promote blood circulation, dilate blood vessels, improve local blood circulation in the lower limbs, promote metabolism, prevent thrombosis, and prevent muscle atrophy. In the early stages of myasthenia gravis, patients often experience limb discomfort, numbness, pain, blurred vision, and fatigue. In work and daily life, it is common to experience tiredness, memory loss, slow responses, and reluctance to be active. Soaking the feet can promote blood circulation and can improve local blood flow, which has a certain beneficial effect on myasthenia gravis. As the disease progresses, there is obvious fatigue and weakness in the skeletal muscles, especially after fatigue in the afternoon and evening, which is reduced in the morning or after rest.
