Quick Answer: Sleep and Anxiety
Anxiety and poor sleep feed each other in a vicious cycle: anxiety makes it hard to fall asleep (racing thoughts, body tension), and sleep deprivation makes anxiety worse (by amplifying the amygdala fear response by 60%). Breaking the cycle requires addressing both sides. The most effective approaches: CBT-I (cognitive behavioural therapy for insomnia), a consistent sleep schedule, a wind-down routine that addresses thoughts (journaling, not just screens off), and creating a bedroom that feels safe and calm. Sleeping pills are not the answer as they do not address the root cause.

The Anxiety-Sleep Cycle
Anxiety activates your sympathetic nervous system (fight-or-flight). Heart rate increases, muscles tense, cortisol rises, and your brain enters a hypervigilant state. This is the opposite of the relaxation response needed for sleep. You lie in bed, mind racing, body tense, clock-watching, which creates anxiety about sleep itself (performance anxiety). Now you are anxious about being anxious, and the cycle deepens.
What Sleep Deprivation Does to Anxiety
UC Berkeley research showed that one night of sleep deprivation increases amygdala reactivity (the brain fear centre) by 60%. The prefrontal cortex (rational thinking) becomes disconnected from the amygdala, meaning your emotional reactions are stronger and your ability to calm yourself is weaker. After just one poor night, anxiety-provoking stimuli feel 60% more threatening. After chronic short sleep, baseline anxiety levels elevate measurably. This is not a mindset issue. It is neurobiology.
Techniques That Actually Break the Cycle
The Evening Anxiety Protocol
(1) Worry journal (8 PM): Write down everything worrying you. For each item, write one small action you will take tomorrow. This externalizes the worry and tells your brain "it is handled." (2) Stimulus control: Only go to bed when sleepy. If you cannot sleep after 20 minutes, get up, go to another room, do something boring (not your phone), and return when sleepy. This breaks the bed-anxiety association. (3) Body scan relaxation: In bed, systematically tense and release each muscle group from toes to head. This redirects attention from thoughts to physical sensation and releases tension. (4) 4-7-8 breathing: Inhale for 4 coun
ts, hold for 7, exhale for 8. The extended exhale activates the parasympathetic nervous system. Do 4 cycles. (5) Paradoxical intention: Try to stay awake with your eyes open. This removes the pressure to fall asleep and often triggers sleep naturally.
Creating an Anxiety-Friendly Bedroom
- Remove clocks: Clock-watching amplifies anxiety. Turn your clock away or remove it. Set your alarm and trust it
- Comfortable bedding: Physical comfort reduces the body tension that feeds anxiety. A supportive mattress, weighted blanket (deep pressure activates calming), and soft sheets all help
- Cool temperature: Anxiety raises body temperature. A cool room (15-19C) counteracts this and facilitates the body temperature drop needed for sleep
- Minimal stimulation: No screens, no bright lights, no work materials visible. Your bedroom should signal safety and rest to your brain
- Consistent routine: Predictability reduces anxiety. Same sequence every night tells your brain what is coming and begins the transition to sleep mode
When to Get Professional Help
Self-help techniques work for mild to moderate anxiety-related sleep issues. Se
ek professional help if: anxiety disrupts sleep more than 3 nights per week for over a month, you are having panic attacks at night, sleep deprivation is significantly affecting work or relationships, you are self-medicating with alcohol or drugs, or you have thoughts of self-harm. CBT-I (Cognitive Behavioural Therapy for Insomnia) is the gold-standard treatment. It is more effective than sleeping pills for anxiety-related insomnia and the results last after treatment ends. Available through psychologists and some online programs in Canada.
Frequently Asked Questions
Should I take sleeping pills for anxiety-related insomnia?
Sleeping pills address the symptom (not sleeping) but not the cause (anxiety). They can be useful short-term during a crisis, but they do not teach your brain to sleep on its own and can create dependency. CBT-I is more effective long-term. Discuss with your doctor.
Does a weighted blanket help with sleep anxiety?
Yes, for many people. The deep pressure stimulation activates the parasympathetic nervous system, reducing heart rate and cortisol. Research shows significant anxiety reduction in many users. Try 10% of your body weight. Not a cure for clinical anxiety, but a helpful tool alongside other strategies.
Why is my anxiety worse at night?
During the day, you are busy and distracted. At night, in a quiet dark room with nothing to do, your brain has space to generate worry. This is normal. The techniques above (journaling, body scan, breathing) give your brain something constructive to do instead of worrying.
Can exercise help anxiety and sleep?
Yes. Regular exercise is one of the most effective anxiety treatments available. It reduces cortisol, increases endorphins, and improves sleep quality. 30+ minutes of moderate exercise, ideally in the morning or afternoon (not within 2-3 hours of bedtime). Walking counts.
