7. Stop your mind racing
For deeper, more peaceful sleep, get 'to do' lists out of your head and onto paper before you go to bed.
You will no doubt have lots of things to do swimming round in your head but try keeping a notebook in the kitchen (not in the bedroom) and write down your to'do list before you go to bed as part of your wind down routine. Doing this keeps the gremlins away from sleep both physically and mentally.
