(HealthDay News) -- Although multiple sclerosis lasts a lifetime, symptoms may come and go.

The American Academy of Family Physicians says it's important to stay as healthy as possible, despite your illness. The academy offers these suggestions:

• Stick to a healthy diet with nutritious foods that are low-fat and fiber-rich.
• With your doctor's approval, exercise regularly. Stretching is an excellent way to manage stiffness and help improve mobility.
• Get plenty of sleep each night, and rest when you need it.
• Avoid extreme temperatures, especially extreme heat. Take care when using hot tubs or saunas.
• Ask family, friends and other loved ones for support and encouragement.
