In brief: Stress and sleep problems can reinforce each other. Worry and heightened arousal make it harder to sleep, while poor sleep reduces resilience the next day.
The typical cycle
| Step | Consequence |
|---|---|
| Daytime stress | More arousal and rumination at night |
| Poor sleep | Fatigue and lower resilience |
| Worry about sleep | More pressure in bed |
| Chronic pattern | Insomnia can become self-perpetuating |
What helps?
- Keep a consistent wake time.
- Limit late caffeine and alcohol.
- Exercise regularly.
- Reduce evening work and rumination time.
For chronic insomnia, cognitive behavioural therapy for insomnia (CBT-I) is the preferred first-line treatment.[1]

Conclusion
