Lifestyle and home remedies
To help relieve the signs and symptoms of MS, try to:

Get plenty of rest. Look at your sleep habits to make sure you're getting the best possible sleep. To make sure you're getting enough sleep, you may need to be evaluated — and possibly treated — for sleep disorders such as obstructive sleep apnea.
Exercise. If you have mild to moderate MS, regular exercise can help improve your strength, muscle tone, balance and coordination. Swimming or other water exercises are good options if you have intolerance to heat. Other types of mild to moderate exercise recommended for people with MS include walking, stretching, low-impact aerobics, stationary bicycling, yoga and tai chi.
Cool down. MS symptoms may worsen when the body temperature rises in some people with MS. Avoiding exposure to heat and using devices such as cooling scarves or vests can be helpful.
Eat a balanced diet. Since there is little evidence to support a particular diet, experts recommend a generally healthy diet. Some research suggests that vitamin D may have potential benefit for people with MS.
Relieve stress. Stress may trigger or worsen your signs and symptoms. Yoga, tai chi, massage, meditation or deep breathing may help.
