Prevention of colds: regular routine, avoid contact with infected people, reasonable diet, sun exposure, can be vaccinated (patients with post-vaccine demyelinating disease can not be vaccinated). Avoid exertion: exertion will affect the immune system through the central nervous system, overload exercise not only affects the body temperature, body fluid pH, but also causes physiological disorders of nerve conduction (use-dependent conduction abnormality). Avoid high temperature: body temperature increases due to the impact on nerve conduction, you can drink water cooled to room temperature and eat cold beverages appropriately; sun exposure should be careful. Appropriate exercise: hydrotherapy, swimming, stretching and muscular activity is within the capacity of many patients with multiple sclerosis. MS patients have the ability to do some degree of training, in order not to appear obvious fatigue.
