Worry and sleep
Worry can get in the way of sleep. It is common to worry about not being able to sleep, which in itself can make the problem worse. It is also common to lie awake at night worrying about particular problems, and they often seem worse at night. This is not helpful.
Remember, the bedroom is for sleep and sex only.
Try to set aside a time to deal with worries earlier in the day.
Write down the problem and what you are planning to do about it.
If worries still bother you during the night, it can be helpful to jot them down on a piece of paper at the side of the bed and then “disown” them until tomorrow when you can consider them more clearly.
