What Causes Numbness and Weakness in the Limbs?

Given the patient’s symptoms—numbness and weakness in all four limbs—it is most likely attributable to improper sleeping posture during the noon nap, leading to exposure to wind-cold pathogens and compression of cervical nerve roots. However, cardiovascular or cerebrovascular pathology cannot be ruled out. The patient is advised to rest appropriately, avoid excessive physical activity, maintain a relaxed and positive mood, and practice deep breathing regularly. If concerns persist, a comprehensive medical evaluation at a hospital is strongly recommended to ensure accurate diagnosis and appropriate treatment.
