Fibromyalgia and sleep: what to do when you’re exhausted but still can’t sleep
Living with fibromyalgia can mean feeling exhausted all day, only to find you can’t sleep when you finally get into bed.
You might struggle to fall asleep, wake up throughout the night, or sleep for eight hours and still feel as though you slept for one.
Fibromyalgia and sleep problems often go hand in hand, but there isn’t one simple explanation for why this happens. While research is still exploring the relationship, some practical steps can support better sleep without adding more pressure. Understanding the sleep-pain cycle, adjusting your evening routine, and finding ways to settle your nervous system can help you approach rest in a way that works for you.

Fibromyalgia and sleep at a glance
Sleep problems are common in fibromyalgia, but research hasn’t established one clear cause for why.
Nervous system hyperarousal may explain feeling exhausted but still unable to settle into sleep.
Poor sleep can increase pain sensitivity, while pain and flare-ups can make sleep more difficult, creating a cycle that can be hard to break.
A consistent wind-down routine, reduced evening stimulation, and a comfortable sleep environment may help support better sleep.
Gentle breathwork, body scans, and calming activities can help you prepare for rest without forcing sleep.
If sleep problems persist, worsen, or significantly affect your daily life, speak with your GP to investigate possible causes and discuss treatment options.
Why does fibromyalgia make it hard to sleep?
People with fibromyalgia often have difficulty falling asleep, staying asleep, and getting refreshing sleep. However, the reasons for these problems aren’t fully understood, and research into the relationship between fibromyalgia and sleep has produced mixed findings.
What does the research tell us?
Some studies have found that people with fibromyalgia experience lighter, more fragmented sleep. However, a systematic review published in Sleep Medicine Reviews found inconsistent evidence of a distinct fibromyalgia-related pattern in objective sleep measurements. This means researchers haven’t yet found out exactly how changes in sleep physiology contribute to fibromyalgia symptoms.
Other research has explored possible changes in cortisol, which is a hormone involved in the body’s stress response and sleep-wake regulation. Findings have been mixed, so cortisol dysregulation should be considered a possible contributing factor rather than an explanation for sleep problems in fibromyalgia.
Could your nervous system be on high alert?
One hypothesis is that the nervous system remains partly vigilant, even when you’re tired. Increased fight-or-flight activity can make it harder to settle into deeper, more restorative sleep.
Think of it as an overprotective alarm system that continues responding to discomfort, stress, or sensory input as though it needs to stay on guard. This may help explain some people’s experiences, but it doesn’t mean everyone with fibromyalgia has the same sleep pattern.
Why do I feel exhausted but can’t sleep?
You can feel exhausted but can’t sleep when you need rest, but your body and mind struggle to settle. Fatigue and sleepiness are related, but aren’t the same, so you can feel physically drained without being able to fall asleep easily.
Understanding the tired-but-wired feeling
Some people find their sleep feels worse after overexertion or during a flare-up. I hear this anecdotally in practice, although research hasn’t established a single explanation for why it happens.
Feeling wired doesn’t mean you aren’t genuinely tired. Rather than putting more effort into making sleep happen, it may help to explore what makes your body feel more comfortable and settled.
How can poor sleep make fibromyalgia pain worse?
Poor sleep can increase pain sensitivity, while pain itself can make it harder to sleep. This two-way relationship is often called the sleep-pain cycle, and it can contribute to more difficult symptoms over time.
Understanding the sleep-pain cycle
Sleep helps the brain regulate pain. When your sleep is repeatedly reduced or disrupted, your brain can become less effective at controlling pain signals, making ordinary sensory input more likely to result in pain.
The cycle can look like this:
Pain makes it harder to sleep
Reduced sleep increases pain sensitivity
More pain makes the following night harder
Repeated nights of bad sleep can have a greater effect than a single poor night. However, one bad night doesn’t automatically mean you’ll have a flare-up.
Why sleep is still worth prioritising
Even when sleep feels unrefreshing, it still matters for your health and daily functioning. A difficult night doesn’t mean sleep hasn’t provided any benefit.
The goal isn’t perfect sleep every night. It’s to create conditions that give your body a better opportunity to rest, while recognising that some nights will still be more difficult than others.
How can you improve sleep with fibromyalgia?
Improving sleep with fibromyalgia often involves making small, sustainable changes to your routine and environment. Instead of overhauling everything at once, start with one or two manageable adjustments and build from there.
1. Create a consistent wind-down routine
A wind-down routine can signal the end of the day and reduce stimulation before bed. You could try:
Dim the lights: Lower bright lighting around an hour before bed to create a calmer environment
Reduce screen stimulation: Put away work, social media, or other stimulating content, or choose something quieter if you use a screen to relax
Follow a familiar sequence: For example, have a warm shower, change into comfortable clothes, make a (caffeine-free!) drink, and read or listen to something calming
Keep your timing reasonably consistent: Aim for a regular wake-up time and a bedtime routine that works with your natural sleepiness
Avoid turning the routine into another task: Choose a few steps you enjoy rather than creating a long checklist you feel pressured to complete
The aim is to make the transition into sleep feel more predictable. You don’t need to follow the routine perfectly for it to be useful.
2. Try gentle nervous system regulation before bed
Calming techniques may help reduce alertness that can make it hard to fall or stay asleep. They aren't guaranteed to help you fall asleep, but they can give you something gentle to focus on while you’re preparing for rest.
Try a simple breathing exercise:
Find a comfortable position, either sitting or lying down
Allow your breathing to settle into a natural rhythm
Gently breathe in through your nose, then breathe out slowly without forcing the breath
If it feels comfortable, make the exhale slightly longer than the inhale
Continue for a few minutes, then return to normal breathing
You can also try a body scan by slowly bringing your attention to different parts of your body, starting at your feet and moving upwards. Notice areas of comfort, tension, or contact with the bed without trying to change anything.
If focusing on your body makes you more uncomfortable, try listening to a familiar audiobook or podcast, calming music, or another gentle distraction instead. The best technique is one that helps you feel more settled, not one you feel you have to push through.
3. Adjust your sleep environment
Fibromyalgia can involve sensitivity to temperature, noise, light, and touch. Consider whether any of these changes would make your bedroom more comfortable:
A cooler room or adjustable bedding
Blackout curtains or softer lighting
Less background noise
Bedding textures, pillows, or sleepwear that feel comfortable against your skin
There’s no single ideal setup. Choose what works for your sensory preferences rather than following rigid rules.
What should you do when you’re lying awake at 2 am?
If you’re wide awake and becoming frustrated, try not to force sleep. Getting out of bed briefly to read, listen to something calming, or do another quiet activity in dim lighting might help you settle until you feel sleepy again.
If pain, fatigue, or mobility limitations make getting up difficult, try changing position or doing something calming in bed. The aim is to reduce frustration and give yourself another opportunity to rest, rather than follow a strict rule.
When should you seek further support for sleep problems?
If your sleep problems are persistent, worsening, or significantly affecting your daily life, speak with your GP or another health professional. Other conditions can contribute to sleep difficulties, particularly if you experience loud snoring, gasping during sleep, significant daytime sleepiness, or unusual movements that repeatedly disturb your sleep.
Your doctor can review your symptoms, medications, and possible contributing factors, and recommend further assessment or treatment where appropriate. For ongoing insomnia, cognitive behavioural therapy for insomnia (CBT-I) is an evidence-based option that may help address your sleep difficulties.
Frequently asked questions about fibromyalgia and sleep
-
Fatigue and sleepiness aren’t the same thing. Some people with fibromyalgia have heightened nervous system alertness, pain, or sensory discomfort that makes it difficult to settle into sleep, even when they feel physically exhausted.
-
Poor sleep can increase pain sensitivity and worsen symptoms, particularly when you don’t sleep well over several nights. However, flare-ups can be due to multiple factors, and one bad night doesn’t automatically mean you’ll have a flare-up
-
If you’re wide awake and becoming frustrated, getting up briefly for a quiet activity might help. If pain or fatigue makes this difficult, you can adapt the approach by changing position or doing something calming in bed.
-
Gentle breathing exercises can help you feel less alert and support relaxation before bed. They’re not guaranteed to make you fall asleep, though, so choose a technique that feels comfortable and avoid forcing your breathing.
-
Fibromyalgia can come with unrefreshing sleep, meaning you can sleep for several hours and still wake feeling tired. If this persists or worsens, speak with your GP to investigate possible contributors, including other sleep disorders.
-
Seek medical advice if sleep problems are ongoing, significantly affect your daily life, or come with symptoms like loud snoring, gasping, or excessive daytime sleepiness. Your doctor can assess possible causes and discuss appropriate treatment options.
