Sleep and MS

We all know sleep is important, but for people living with MS, getting a good night’s sleep is essential in supporting overall health, energy levels, and daily well-being.  Research shows that sleep and MS are connected. Poor sleep can make MS symptoms feel worse, and MS symptoms can also make it harder to sleep. This can create a cycle that affects health and daily life.

Your body has a natural 24-hour “body clock,” called the circadian rhythm. This clock helps control when you feel awake and when you feel sleepy. It also affects things like hormones, body temperature, metabolism, and the immune system.

When this body clock is disrupted, sleep can become less restful. It may also affect the immune system and increase inflammation in the body. Because MS involves the immune system, researchers are interested in how these changes may play a role in the condition. Read here for more information about research in this area. 

Sleep Supports Brain Health

Sleep is a time when the brain does important maintenance work. During sleep, the brain:

• Helps you learn and remember things 
• Supports focus and thinking 
• Affects mood and emotional well-being 
• Helps repair nerve cells 
• Clears waste that builds up during the day 

Because MS affects the brain and spinal cord, these processes are especially important.

Many people with MS have trouble sleeping, like:

• Trouble falling asleep or staying asleep (insomnia) 
• Breathing problems during sleep (sleep apnea) 
• An uncomfortable urge to move the legs at night (restless legs syndrome) 

These sleep problems can lead to tiredness, trouble concentrating, mood changes, and a lower quality of life.

MS Symptoms can Affect Sleep

Several MS symptoms can make it harder to get a good night's rest, including:

• Pain or discomfort
• Muscle spasms
• Frequent trips to the bathroom during the night
• Anxiety, stress, or depression

At the same time, poor sleep can make some of these symptoms feel worse.

Other Factors that can Affect Sleep

Sleep can be affected for reasons other than MS symptoms. Some medications used in MS can interfere with sleep and make it harder to fall or stay asleep. Lifestyle factors, including irregular sleep schedules, longer daytime naps, low physical activity levels, and poor sleep habits (like late screen use), can also disturb the sleep cycle. Some people with MS may be sensitive to heat, and becoming overheated at night can also make sleep less restful.

Fatigue is one of the most common MS symptoms, and it’s different from being tired. Even when you get a full night’s sleep, MS fatigue can still be present. Sleep problems can make MS fatigue worse, leaving you feeling even more drained. 

Poor sleep also affects how clearly you think; many people notice slower processing, trouble concentrating, or difficulty remembering things when their sleep isn’t good. Improving sleep won’t cure MS fatigue, but it can make a meaningful difference in daytime energy, mood, and cognitive clarity.

If you’re having trouble sleeping, talk to your healthcare team. There are strategies that may help, like:

• Keeping a regular sleep schedule
• Limiting caffeine later in the day
• Creating a quiet, comfortable sleep environment
• Treating underlying sleep disorders
• Cognitive Behavioral Therapy for Insomnia (CBT-I)

Sleep is an important part of overall health and brain health. For people with MS, improving sleep may help support energy levels, mood, thinking, and quality of life. As researchers learn more about the connection between sleep and MS, the more we understand that a good night's sleep is an important part of managing MS care.

What you can do 

Paying attention to your sleep patterns is a good first step. Some find it useful to track their sleep for a few weeks noting what time they go to bed, how long it takes to fall asleep, how rested they feel in the morning, and if anything interrupts their sleep, including symptoms, caffeine, or alcohol.

Daily habits can make sleep easier, like keeping a steady routine to help your body know when it’s time to wind down. A calm period with dimmed lights, reduced screen time, and smaller evening meals may also make it easier to fall asleep. 

Here are some things you can try to sleep better:

• Simple mental exercises, like counting sheep or repeating a word or phrase in your mind.
• Visualization involves imagining yourself falling asleep in a calm, peaceful place.
• Progressive relaxation means relaxing your body one part at a time by tensing and then letting go of your muscles. People who experience spasticity should be careful when using this method.
• Take only short rest periods during the day. Long naps can make it harder to sleep at night.
• Limit screen time before bedtime. Research has proven that portable screen devices contribute to poorer sleep quantity and quality and excessive daytime sleepiness. 
• Some try herbal supplements like melatonin, but it’s important to speak to your healthcare team before trying anything new. Some supplements may interact with other medications or affect the immune system, so they may not be recommended for people living with MS.
• Talk to your doctor about sleep apnea. Up to 50% of people with MS are affected, and most are untreated.  Long term treatment for sleep apnea is linked to reduced fatigue and improved physical health in people living with MS.

Comfortable sleeping conditions also matter. This means having a supportive mattress and pillow, and a cool, dark, quiet room. If nighttime MS symptoms keep you up, talk with your MS healthcare team about ways to manage pain, spasms, bladder issues, or medication timing.

If you regularly wake up unrefreshed, snore loudly, or feel sleepy during the day, you could ask about a sleep assessment. Screening can show problems like sleep apnea or restless leg syndrome, both of which can be managed with treatments.

It’s a good idea to talk to your MS care team if you have trouble sleeping and it's affecting your energy, mood, or daily activities. You should also connect with your healthcare team if you or someone close to you notice snoring, gasping, or pauses in breathing during sleep.

Sleep problems may not always be brought up during medical visits. Because of this, they can sometimes go unrecognized even though they may have a big impact on daily life and symptoms.

Getting support early can help prevent symptoms from getting worse and can improve overall quality of life.
