Lying awake with a racing mind is one of the most common complaints in people with anxiety. Anxiety raises alertness, and poor sleep in turn lowers the brain’s ability to regulate emotions, so each can make the other worse. Breaking this cycle usually involves both calming the mind and building sleep-friendly habits. This guide explains what is happening and what helps.
Why anxiety disrupts sleep
Anxiety keeps the body’s stress response switched on, with raised heart rate, muscle tension and heightened vigilance, which is the opposite of the relaxed state needed to fall asleep. At night there are fewer distractions, so worries feel louder. Many people then start to worry about sleep itself, checking the clock and calculating how little rest they will get. This sleep-related worry creates more arousal and can turn a few bad nights into a lasting pattern.
What helps: habits that support sleep
- Keep a regular schedule. Go to bed and get up at similar times, including weekends.
- Create a wind-down routine. Spend 30 to 60 minutes doing something calm, such as reading, stretching or a warm shower, with screens dimmed or off.
- Watch caffeine and alcohol. Caffeine can stay active for many hours, and alcohol may help you drop off but tends to fragment sleep later in the night.
- Make the bedroom cool, dark and quiet. Use the bed for sleep rather than for working or scrolling.
- Move during the day. Regular physical activity is linked to better sleep, but avoid very intense exercise right before bed.
What helps: calming a racing mind
Do your worrying earlier
Try a scheduled worry period in the early evening, writing down concerns and one possible next step for each. This gives your mind permission to put them down at night. Our guide to the worry time technique shows how.
Use slow breathing or muscle relaxation
Slow breathing, with a longer out-breath than in-breath, and progressive muscle relaxation, tensing and releasing each muscle group in turn, help reduce physical arousal. They work best when practised regularly, not only when you are already distressed.
Step back from night-time thoughts
Thoughts at 3 a.m. often feel more catastrophic than they are. Notice them as thoughts rather than facts, using cognitive defusion, and remember that catastrophic predictions can be revisited in daylight.
If you cannot sleep, get up
If you have been awake for what feels like twenty minutes or more, leave the bed and do something quiet in dim light until you feel sleepy. This stimulus control technique, used in cognitive behavioral therapy for insomnia, helps your brain link the bed with sleep rather than frustration. Avoid watching the clock.
When to seek help
Occasional bad nights are normal. See a doctor if sleep problems last more than a few weeks, affect daytime functioning, or come with persistent anxiety, low mood, loud snoring or breathing pauses. Cognitive behavioral therapy for insomnia is widely recommended as a first-line treatment for long-term sleep problems.

Frequently asked questions
Can anxiety cause insomnia?
Yes. Anxiety is a common cause of difficulty falling asleep and staying asleep, and poor sleep can in turn worsen anxiety.
Why is my anxiety worse at night?
Fewer distractions, tiredness and a quiet environment make worries louder, and fatigue reduces your ability to regulate emotions.
Should I take sleeping tablets for anxiety?
Only after talking to a doctor. Medicines can have side effects and risks of dependence, and behavioral approaches are usually preferred for long-term sleep problems.
