Insomnia is when you have an ongoing problem with getting to and staying asleep. It usually gets better if you change your sleeping habits.
You may 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
do not feel rested in the morning
feel tired and irritable during the day
find it difficult to concentrate during the day because you're tired
You can have these symptoms for months, sometimes years.
Everyone needs different amounts of sleep.
On average we need:
Adults – 7 to 9 hours
Children – 9 to 13 hours
Toddlers and babies – 12 to 17 hours
The most common causes of insomnia are:
stress, anxiety or depression
a room that's too hot or cold
an uncomfortable bed
smoking or drinking alcohol or caffeine close to your bedtime
watching a television or using a smartphone close to your bedtime
Some illnesses and medicines can disrupt sleep. Talk to your GP if you are concerned about this.
How you can treat insomnia yourself:
Insomnia usually gets better if you change your sleeping habits.
Watching television or using devices such as a smartphone in bed can result in poor sleep. This happens because the bright light of these devices tells your brain to wake up and not go to sleep.
If you watch television in bed, try removing it from your bedroom. Avoid using your smartphone or laptop for about 1 hour before your bedtime.
Avoid smoking and drinking alcohol, tea, coffee or other stimulating drinks at least 6 hours before going to bed.
go to bed and wake up at the same time every day
decide on a suitable bedtime when you usually feel tired - it's not helpful to go to bed if you're not ready for sleep
relax for at least 1 hour before bed – for example, take a bath or read a book
make sure your mattress, pillows and covers are comfortable
exercise regularly during the day
The following things may also contribute towards a bad night's sleep:
Eating a big meal late at night
Exercising at least 4 hours before bed
Napping during the day
Driving when you feel sleepy
Sleeping in, for example at weekends – stick to your regular sleeping hours instead
It's important to see your GP if:
changing your sleeping habits has not worked
you've had trouble sleeping for months
your sleep problems are affecting your daily life
Your GP will try to find out what's causing your insomnia so you get the right treatment.
Sometimes you will be referred to a therapist for support. Talking with a professional can help you change how you think about your sleep and help improve your sleeping habits.
