Anxiety and Insomnia: Why Your Mind Races at Night (and What Helps)

You’re exhausted, but the moment your head hits the pillow your mind starts racing. Anxiety and insomnia feed each other: worry keeps you awake, and poor sleep makes anxiety harder to manage the next day. The good news is that there’s a well-studied, drug-free treatment designed exactly for this cycle.

Why anxiety keeps you awake

When you’re anxious, your body’s stress response keeps you alert — your heart rate rises, your muscles tense, and your brain scans for problems. Lying in the dark with nothing else to focus on gives worries room to grow. Over time, many people start to associate the bed itself with frustration and alertness, which makes sleep even harder. The National Institute of Mental Health lists sleep problems among the common symptoms of generalized anxiety disorder.

CBT-I: the first-line treatment for chronic insomnia

The American College of Physicians recommends cognitive behavioral therapy for insomnia (CBT-I) as the initial treatment for chronic insomnia in adults (Qaseem et al., 2016). CBT-I usually combines:

• Stimulus control — using the bed only for sleep and sex, and getting up if you can’t sleep
• Sleep restriction — temporarily limiting time in bed to strengthen your natural sleep drive (best done with guidance)
• Cognitive work — challenging anxious thoughts about sleep, like “If I don’t sleep, tomorrow will be a disaster”
• Sleep hygiene — consistent wake times, less caffeine late in the day, a wind-down routine
• Relaxation techniques — slow breathing, progressive muscle relaxation

What you can try tonight

1. Get up at the same time every day, even after a bad night.
2. If you’re awake for what feels like 20 minutes or more, get up, do something calm in dim light, and go back when sleepy.
3. Schedule a “worry time” earlier in the evening and write worries down with one next step.
4. Cut caffeine after early afternoon and avoid alcohol as a sleep aid.
5. Keep screens out of bed; try a slow-exhale breathing exercise instead.

When to get help

Talk to a doctor if poor sleep lasts for weeks, affects your daytime functioning, or comes with loud snoring or breathing pauses (a possible sign of sleep apnea). If anxiety is driving the problem, therapy that addresses both — CBT for anxiety and CBT-I techniques for sleep — can help.
