Can Anxiety Cause Insomnia? How Worry and Stress Can Affect Your Sleep
Can Anxiety Cause Insomnia?
Yes, anxiety can contribute to insomnia and other sleep problems.
You may feel physically exhausted after a long day, but as soon as you lie down, your mind becomes more active. Thoughts about tomorrow, work, relationships, money, health, or other worries may begin to race through your mind.
The more you worry, the more difficult it can become to relax. Then, when you realise that you are still awake, you may start worrying about not getting enough sleep.
This can create a frustrating cycle:
Anxiety → Racing thoughts → Difficulty sleeping → Daytime exhaustion → More anxiety → Another difficult night
If you have been asking, “Can anxiety cause insomnia?”, understanding the connection between anxiety and sleep may help you identify what is contributing to your symptoms.
How Can Anxiety Cause Insomnia?
Anxiety can place your body and mind in a more alert state.
When you feel worried or stressed, your brain may focus on potential problems or threats. This can make it difficult to transition into the relaxed state needed for sleep.
Anxiety-related sleep problems may involve:
- Difficulty falling asleep
- Racing thoughts
- Constant worrying
- Feeling physically tense
- A fast heartbeat
- Restlessness
- Waking frequently during the night
- Waking up feeling anxious
- Difficulty falling back asleep
- Feeling tired but unable to sleep
For some people, anxiety mainly affects falling asleep. For others, it may cause repeated waking or early-morning waking.
If you regularly feel exhausted but become more alert once you get into bed, you may also want to read our guide on why you are so tired but can’t sleep.
Why Does Anxiety Get Worse at Night?
During the day, you may be busy with work, family, conversations, responsibilities, and other distractions.
At night, the environment becomes quieter.
Without those distractions, worries that you pushed aside earlier may suddenly become more noticeable.
You may start thinking:
- “What if something goes wrong tomorrow?”
- “Did I make the right decision?”
- “What am I going to do about this problem?”
- “Why did I say that earlier?”
- “What if I can’t sleep tonight?”
These thoughts can keep your brain engaged when you are trying to rest.
If your mind becomes especially active as soon as you lie down, our guide on how to stop overthinking at night explores practical ways to manage racing thoughts before sleep.
What Does Anxiety-Related Insomnia Feel Like?
Anxiety-related insomnia can feel different from simply having an occasional bad night of sleep.
You may feel extremely tired, but your body and mind seem unable to settle.
Common experiences include:
- Feeling sleepy on the sofa but suddenly awake in bed
- Thinking about problems repeatedly
- Checking the time throughout the night
- Feeling anxious about how little sleep you are getting
- Tossing and turning
- Waking suddenly with a feeling of worry
- Feeling physically tense
- Waking too early and being unable to return to sleep
- Feeling exhausted and unfocused the following day
Over time, some people begin to associate bedtime with frustration and worry.
Instead of thinking of bed as a place to rest, they start expecting another difficult night.
To understand the wider range of sleep difficulties people may experience, explore our detailed guide on what insomnia feels like and its common symptoms.
Can Anxiety Cause You to Wake Up in the Middle of the Night?
Yes, anxiety may contribute to waking during the night.
You may wake up with your mind immediately becoming active. Some people begin thinking about a problem as soon as they wake, making it difficult to return to sleep.
You might also experience:
- A racing heartbeat
- Sweating
- Muscle tension
- A feeling of uneasiness
- Racing thoughts
- Worry about the time
However, waking during the night can have many possible causes. Stress and anxiety are only some of the factors that may affect sleep.

Can Anxiety Cause Chronic Insomnia?
Anxiety and insomnia can sometimes reinforce each other over time.
For example:
Anxiety makes it difficult to sleep → Poor sleep increases stress and emotional sensitivity → You worry about another bad night → Sleep becomes even more difficult.
This pattern can become particularly frustrating because you may start worrying about sleep itself.
You may begin asking:
- “What if I don’t sleep tonight?”
- “How will I function tomorrow?”
- “Why can’t I just fall asleep?”
- “Is something wrong with me?”
The pressure to sleep can sometimes increase alertness rather than reduce it.
Persistent insomnia should be assessed by a qualified healthcare professional, particularly when it is affecting your daily functioning.
For evidence-based information about persistent insomnia and recommended treatment approaches, you can review guidance from a recognised health authority.
How to Sleep Better When Anxiety Is Keeping You Awake
There is no single solution that works for everyone, but the following strategies may help create better conditions for sleep.
1. Create a Wind-Down Routine
Give yourself time to transition from daytime activities into rest.
You might:
- Take a warm shower
- Read something calming
- Listen to relaxing audio
- Do gentle stretching
- Write down tomorrow’s tasks
- Reduce stimulating activities before bed
A consistent routine can help create a clearer boundary between a busy day and bedtime.
2. Write Down Your Worries
If your thoughts become overwhelming at night, consider writing them down before bed.
You can separate them into two lists:
What I am worried about
and
What I can do tomorrow
This may help you organise your thoughts instead of repeatedly reviewing them in bed.
For additional strategies that may help when your thoughts will not slow down, read our guide on how to stop racing thoughts and overthinking at night.
3. Avoid Turning Bedtime Into a Countdown
Repeatedly checking the clock can increase pressure.
You may start calculating:
“I only have six hours left.”
Then:
“Now I only have five.”
This can increase anxiety about sleep.
If clock-watching is making you more worried, try turning the clock away or keeping your phone out of immediate reach.
4. Reduce Stimulation Before Bed
Social media, work emails, upsetting news, arguments, gaming, and other highly stimulating activities can make it harder to wind down.
Try creating a calmer period before sleep.
This could involve:
- Dimming lights
- Putting away work
- Reducing social media use
- Avoiding stressful conversations when possible
- Choosing a relaxing activity
You can also review trusted guidance on healthy sleep habits and creating a calming bedtime routine for additional evidence-based recommendations.
5. Keep a Consistent Wake-Up Time
Try to wake up at approximately the same time each day when possible.
A consistent routine can help support your natural sleep-wake cycle.
Avoid dramatically changing your schedule after every poor night of sleep.
6. Address Anxiety During the Day
Sleep problems are not always solved only at bedtime.
If anxiety is affecting your sleep, consider what may be contributing to your worry during the day.
This might include:
- Work stress
- Relationship difficulties
- Financial concerns
- Major life changes
- Ongoing uncertainty
Speaking with a qualified healthcare professional or mental health professional may help you develop appropriate strategies for managing persistent anxiety.
Anxiety, Panic Attacks and Nighttime Sleep Problems

However, these symptoms can have different possible causes.
If you experience new, severe, or concerning symptoms, seek appropriate medical advice.
If you have experienced sudden episodes of intense fear or physical symptoms, our guide on what a panic attack feels like explains common symptoms and when to seek help.

Frequently Asked Questions
Can anxiety cause you not to sleep at all?
Severe anxiety can make it difficult to fall asleep or stay asleep. However, persistent or severe sleep loss should not automatically be attributed to anxiety, as other health or sleep-related factors may also contribute.
Can anxiety make you tired but unable to sleep?
Yes. Anxiety can be mentally and physically exhausting while also keeping your nervous system alert. This can create the feeling of being extremely tired but unable to relax enough to fall asleep.
Learn more about this frustrating experience in our guide, why am I so tired but can’t sleep?
Why do I feel more anxious at night?
Nighttime can feel more difficult because there are fewer distractions. This may give worries, fears, and unresolved thoughts more attention.
Can anxiety wake you up at night?
Anxiety may contribute to nighttime waking and difficulty returning to sleep. However, repeated waking can have many possible causes.
How can I calm anxiety before bed?
A calming routine, writing down worries, reducing stimulation, relaxation techniques, and addressing persistent anxiety during the day may help. If anxiety regularly interferes with your sleep, consider speaking with a healthcare professional.
Final Thoughts: Can Anxiety Cause Insomnia?
Yes, anxiety can contribute to insomnia by making it harder for your mind and body to relax.
Worry, racing thoughts, physical tension, and fear about not sleeping can create a cycle where anxiety affects sleep and poor sleep increases anxiety.
If you regularly struggle to sleep because your mind will not switch off, focusing on both your daytime anxiety and your nighttime routine may help.
Small changes such as creating a wind-down routine, writing down worries, reducing evening stimulation, and avoiding repeated clock-checking can support better sleep habits. Persistent anxiety or insomnia, however, may require professional assessment and appropriate treatment.
