What should you know about hyperarousal insomnia?

The nervous system can remain watchful when you are stressed, worried, unwell, or adjusting to a disrupted schedule. You may feel tired but unable to switch off, notice a busy mind at bedtime, wake easily, or become alert after waking in the night. Poor sleep can then increase daytime sleepiness, irritability, and difficulty concentrating. Burnout, depression, generalised anxiety disorder, jet lag, medicines, and physical symptoms can all affect sleep, so the pattern deserves context rather than a single label.

Keep a steady wake time, use daylight and gentle activity during the day, and reserve the bed for sleep and intimacy. Dim lights before bed, move worries onto paper, and use a calm routine such as reading or quiet breathing. If you remain awake and frustrated, leave the bed briefly for a quiet activity and return when sleepy. Record sleep timing, naps, caffeine, alcohol, medicines, and stressors to discuss with a clinician.

Arrange medical advice when poor sleep persists, affects work or driving, or leaves you struggling to function during the day. Seek urgent help for thoughts of self-harm, several nights with almost no sleep alongside unusually high energy or risky behaviour, severe confusion, or hallucinations. Prompt review is also appropriate for loud snoring with breathing pauses, new pain, or symptoms after a medicine change.

What may be keeping my nervous system alert? Could a medicine, mood problem, breathing issue, or physical symptom be disturbing sleep? Would a structured insomnia treatment or sleep diary help, and when should I return for review?
