Tips to help with sleep

Go to bed and get up at the same time every day (yes that includes the weekends)

Check your bedroom

  • Check it is not too hot or too cold.
  • Make sure it’s dark – draw the curtains, have a dim night light on if you don’t want it completely dark.
  • Ensure your room is calm, comfortable and tidy.
  • Avoid using devices at least 1 hr before bedtime this includes, mobile phones, tablets and TVs as devices can give off ‘blue light’ which keeps us awake by disrupting Melatonin in the brain.
  •  Establish a bedtime routine that you can stick to every evening
  • Avoid drinking too much before bed (especially drinks with caffeine in like tea, coffee and fizzy drinks)
  • Don’t exercise to closely to your bedtime – try and exercise in the daytime.
  • Try not to nap during the day.
  • Don’t eat a large meal before bed instead try a light snack like a banana and a warm milky drink to prevent you feel hungry during the night.
  • (16-18) Avoid drugs and alcohol before bed.
  • It can be difficult to sleep at times when we are worrying.

Things that can help
