Muscle relaxation of the whole body may be caused by aging, lack of protein, abnormal nerve function, etc. It can be relieved by strengthening exercise, consuming protein-rich food and medication. 1. Aging of the human body: with the growth of age, the body gradually weakens, the elasticity decreases, thus appearing the natural phenomenon of the whole body skin and muscle relaxation gradually. You can improve the state of muscle relaxation by strengthening the exercise to keep the muscles plump and the muscle tension high. 2. Lack of protein: generalized muscle laxity may be caused by a serious lack of protein, due to the loss of subcutaneous fat, resulting in a decrease in skin support, generalized muscle laxity. You can eat more food containing high quality protein such as lean meat, fish and shrimp, dairy products, etc. You can also eat vegetables and fruits, animal organs and other foods to improve the phenomenon of general muscle relaxation. 3. Abnormal nerve function: abnormal nerve function makes the muscles lose innervation, the muscles can not get nerve nutrition to appear muscle relaxation phenomenon. You can take drugs to promote the recovery of muscle cells and accelerate nerve conduction, such as baclofen tablets and eperisone hydrochloride tablets, to make the atrophied and weak muscles recover. If there is a generalized muscle relaxation, it is recommended to consult a doctor in time, under the guidance of the doctor, to clarify the cause of the disease, and take the appropriate treatment plan. The above drugs need to be used under the guidance of a doctor, avoid self-medication.
