About problems Sleeping

Insomnia means you regularly have problems sleeping. It usually gets better by changing your sleeping habits.

You have insomnia if you regularly:

  • find it hard to go to sleep
  • wake up several times during the night
  • lie awake at night
  • wake up early and cannot go back to sleep
  • still feel tired after waking up
  • find it hard to nap during the day even though you’re tired
  • feel tired and irritable during the day
  • find it difficult to concentrate during the day because you’re tired

If you have insomnia for a short time (less than 3 months) it’s called short-term insomnia. Insomnia that lasts 3 months or longer is called long-term insomnia.

Everyone needs different amounts of sleep.

On average:

  • adults need 7 to 9 hours
  • children need 9 to 13 hours
  • toddlers and babies need 12 to 17 hours

You probably do not get enough sleep if you’re constantly tired during the day.

The most common causes are:

  • stress, anxiety or depression
  • noise
  • a room that’s too hot or cold
  • uncomfortable beds
  • alcohol, caffeine or nicotine
  • recreational drugs like cocaine or ecstasy
  • jet lag
  • shift work

Insomnia usually gets better by changing your sleeping habits.


  • go to bed and wake up at the same time every day

  • relax at least 1 hour before bed, for example, take a bath or read a book

  • make sure your bedroom is dark and quiet – use curtains, blinds, an eye mask or ear plugs if needed

  • exercise regularly during the day

  • make sure your mattress, pillows and covers are comfortable


  • do not smoke or drink alcohol, tea or coffee at least 6 hours before going to bed

  • do not eat a big meal late at night

  • do not exercise at least 4 hours before bed

  • do not watch television or use devices, like smartphones, right before going to bed, because the bright light makes you more awake

  • do not drive when you feel sleepy

  • do not sleep in after a bad night’s sleep and stick to your regular sleeping hours instead
