Why worries get louder at bedtime, what actually helps you switch off, and when anxiety at night or insomnia is worth taking to a GP.
The lights are off and your body is tired. Your mind, meanwhile, has started a slideshow: the email you sent at 4pm, your sister's comment, next week's bill.
Anxious thoughts at night usually aren't a sign that something is wrong with your hormones or your brain. Worries get louder when nothing else is competing for your attention. What helps is mostly practical. Get the worries onto paper, give yourself an hour to wind down, and don't lie there arguing with your thoughts.
If it happens most nights, or the worry follows you into the day, that's worth taking to a GP. There's more on when below.
Why Anxiety Gets Louder at Bedtime
Part of it is simply quiet. During the day, work, people and noise crowd out the background worry. In a dark room there's nothing else to look at.
Your stress hormones aren't usually the villain on a normal night. Cleveland Clinic notes that most people have lower cortisol levels in the evening when they go to sleep, with a peak just before waking. Claims that a specific "cortisol curve" causes night-time worry go well beyond the evidence.
Stress and worry, though, do keep people awake. The NHS lists stress, anxiety or depression among the most common causes of insomnia. It also lists difficulty sleeping as a possible symptom of generalised anxiety disorder.
Write the To-Do List, Not the Diary
A lot of night-time worry is really unfinished business. A small sleep-lab study of 57 young adults tested this. Those who spent five minutes writing a to-do list fell asleep significantly faster than those who listed tasks they'd already finished.
Keep a notebook and pen by the bed, not your phone. Write tomorrow's tasks in specific terms ("email Jo about Friday" beats "work stuff"). If a worry isn't a task, write it down anyway, along with a time tomorrow when you'll think about it properly.
That last step borrows from a self-help technique called worry time, which also helps with daytime dread. Giving worries a set slot means the night doesn't have to hold them. If the same thought keeps circling for hours, rumination may be the better name for what's happening.
Give Yourself an Hour to Wind Down
The NHS advice for sleeping problems is plain. It suggests you relax at least 1 hour before bed, for example with a bath or a book, and only go to bed when you're sleepy. It also advises against using devices like smartphones right before bed.
Scrolling in bed has a second cost. It hands your mind fresh material to chew on, right when you want it to slow down.
Breathing exercises help some people settle, but claims that a particular count "lowers cortisol" aren't well supported. Slow breathing with a longer out-breath is easy to try, and breathwork for sleep walks through the options. Progressive muscle relaxation is another: tense one muscle group for a few seconds, let go, and work up from your feet. Both give your attention a job other than worrying.
If You're Still Awake and Stewing
There's no prize for lying there. If you've been awake a while and the thoughts are winning, get up, go somewhere dim and do something dull. Go back to bed when you feel sleepy.
Keep getting up at the same time each morning, even after a bad night. The NHS advises not sleeping in after a bad night's sleep and sticking to your regular hours.
When Night Anxiety Needs More Than Tips
Look for a pattern first. Some women find anxiety and poor sleep cluster in the days before a period, and anxiety and your menstrual cycle explains why that can happen.
See a GP if changing your sleep habits hasn't helped, or if worry is hard to control and affecting your days. The NHS calls insomnia that lasts 3 months or longer long-term insomnia. It says you may be offered cognitive behavioural therapy (CBT), and that sleeping pills are only prescribed for a few days or weeks at most.
For anxiety, adults in England can refer themselves to NHS talking therapies without seeing a GP first. If night-time thoughts turn to harming yourself, call Samaritans on 116 123 in the UK. In the US, call or text 988, free and at any hour. In an emergency, call 999 or 911.
Frequently Asked Questions
Why Is My Anxiety Worse at Night?
At night there's less to distract you, so background worries take up more room. The NHS lists stress and anxiety among the most common causes of insomnia. Cortisol is normally lower in the evening, so a normal hormone rhythm usually isn't the culprit.
What Can I Do When Racing Thoughts Keep Me Awake?
Write tomorrow's tasks and worries on paper by the bed, which helped people fall asleep faster in one small study. If you're still awake and stewing, get up and do something dull in dim light until you feel sleepy. Keep your phone out of reach.
When Should I See a Doctor About Anxiety at Night?
See a GP if changes to your sleep habits haven't helped, or if worry is hard to control and affecting daily life. Insomnia that lasts three months or more is classed as long-term. If you have thoughts of harming yourself, call Samaritans on 116 123 (UK) or 988 (US).
