Almost everyone has the occasional bad night. But when trouble falling or staying asleep continues for weeks, it starts to affect mood, focus and health, and it is often linked with anxiety or depression.
How sleep and mood affect each other
Worry makes it harder to switch off at night, and a tired brain is less able to manage worry the next day. Over time this becomes a cycle that is hard to break on your own.
Low mood can also show up as sleep changes: waking very early, sleeping far more than usual, or never feeling rested.
Habits that help
- Keep a regular wake-up time, even on weekends. A steady morning anchor helps reset your body clock.
- Limit screens, caffeine and heavy meals in the hours before bed.
- Use the bed only for sleep. If you can't sleep after a while, get up, do something calm in dim light, and return when sleepy.
- Get daylight and some physical activity during the day.
When to see a doctor
If poor sleep lasts more than a few weeks, affects your daily life, or comes with low mood, anxiety or alcohol use, speak to a psychiatrist. Therapies such as CBT for insomnia are effective, and any medication should only be taken under medical advice.
