Exercise and Its Positive Impact on Multiple Sclerosis

Even though the symptoms of multiple sclerosis (MS) vary from person to person, experiencing any one of them (e.g., fatigue, muscle spasms/weakness, and mobility issues, to name a few) can be downright brutal.

This is why experts are diligently working to find therapies that, in addition to an MS disease-modifying medication, can further improve a person's symptoms or even, perhaps, help slow down their disease course.

One such therapy that has consistently been found to be beneficial for those living with MS is exercise.

Aside from the "feel-good" chemicals (called endorphins) released during exercise, research suggests that engaging in cardiorespiratory activities (for example, bicycling or swimming) can improve muscle strength, tiredness, cognition (memory and thinking skills), and breathing function in those with MS.

In addition, progressive resistance training—a form of exercise that focuses on building muscle strength—has been found to not only improve muscle strength but also fatigue and mood in some people with MS. 

Flexibility exercises, which stretch the muscles and tendon to their full length, have been found in people with MS to help them maintain balance, reduce spasticity, and enhance joint range of motion. 

Other symptoms or MS-related complications that regular exercise may benefit include:

• Improving bladder and bowel function
• Preventing the loss of bone density (called osteoporosis)
• Reducing depression
• Improving social functioning and quality of life

Lastly, it's important to keep in mind that, besides benefitting your MS health, there are a number of other "positives" to engaging in a regular exercise routine.

Research has found that moderate and/or vigorous exercise decreases your risk of obesity, heart disease, stroke, depression, and certain types of cancer. It can also reduce stress and anxiety, and improve sleep.

In order to reap the benefits of exercise for your MS and overall health, you do not necessarily have to buy a gym membership or pull out your dusty weights or old treadmill. Instead, consider more stimulating, sociable physical activities that are also less expensive—a double bonus.

For example, yoga and tai chi can improve balance and coordination. Likewise, for cardiorespiratory exercises, consider dancing, hiking, swimming, power walking, or joining an organized sport, such as tennis or basketball. Simple everyday activities like gardening and household chores can also get your heart pumping.

For muscle strengthening-exercises, if you are in a wheelchair, consider doing tricep extensions. If you are ambulatory, do squats. Both of these exercises can be performed within the comfort of your own home.

Before embarking on an exercise regimen, it's sensible to first speak with your doctor to ensure your workouts are safe and right for you.

It may also be a good idea to see a physical therapist who has experience working with people with MS. A physical therapist can help you avoid injuries (stretching beforehand is key), as well as come up with exercises that you enjoy and that won't exacerbate your unique MS symptoms.

It's also prudent to keep these following tips in mind if you are heat-sensitive, meaning your MS symptoms tend to worsen or be exacerbated by a rise in your body temperature (which is common):

• Schedule your exercise workouts in the early morning when the temperature is cooler and your body temperature is lower.
• Take a tepid bath a half an hour prior to exercising.
• Stay hydrated by drinking cold water throughout your workouts.
• Use cooling devices while exercising (e.g., cooling vest, cold packs, or spray bottles).
• Wear light-weight, breathable clothing.
• If exercising indoors, ensure the facility or room is air-conditioned.

A Word From Verywell

Doctors used to instruct their patients with MS to avoid exercise out of concern that it would trigger a relapse or worsen underlying symptoms.

We now know that exercise—when performed under the right conditions and when tailored to a person's unique needs and disability level—is actually important for a person's MS and overall health.
