How can I improve my sleep?

Sleep is important for good mental health. This page explains how you can improve your sleep. This information is people affected by mental illness in England who are 18 or over. It is also for their loved ones and carers and anyone else interested in the subject.

How can problems with sleep affect me?

Problems with sleep can affect how you feel physically and mentally. Also, how you feel can affect how you sleep. Certain medications can also affect your sleep, causing you to sleep too much or not enough.

What can I do to get better sleep?

To get better sleep, you can try:

  • Limiting or avoiding using device screens before sleep
  • Relaxing before bed with a warm bath, reading a book or listening to the radio
  • Exercising regularly but avoiding vigorous exercise too close to bedtime
  • Cutting down on caffeine, especially in the evening
  • Avoiding too much food or alcohol late at night
  • Going to bed and waking up at roughly the same time each day
  • Having a bedroom that is dark and quiet
  • Not having a TV in the bedroom

If you cannot get to sleep, you could get up and do something relaxing. Then go back to bed when you feel sleepy.

If you regularly have problems sleeping, then you can discuss this with your GP.

Sometimes, GPs or psychiatrists may offer you medication to help you sleep. But medication for sleep is only recommended as a short-term solution.

Your GP or psychiatrist should give you information about medication, but you can ask them questions too.
