It’s normal to wake briefly during the night.   But if you’re waking up during the night and having trouble falling back asleep, the following tips may help.
Stay out of your head. The key to getting back to sleep is continuing to prepare your body for sleep, so remain in bed in a relaxed position. Hard as it may be, try not to stress over the fact that you’re awake , because that very stress and anxiety encourage your body to stay awake. 
  If you are finding it hard to fall back asleep, try a relaxation technique such as visualization, deep breathing, or meditation, which can be done without even getting out of bed. Remind yourself that although they’re not a replacement for sleep, rest and relaxation still help refresh your body.
Do a quiet, non-stimulating activity. If you’ve been awake for more than 15 minutes, try getting out of bed and doing a quiet, non-stimulating activity, such as reading a book. Keep the lights dim so as not to think that it’s time to wake up.   A light snack might help relax you, but be careful not to eat so much that your body begins to expect a meal at that time of the day.
  If you wake during the night feeling anxious about something, make a brief note of it on paper and postpone worrying about it until the next day when you are fresh and it will be easier to resolve.

A．Make relaxation your goal, not sleep.

B．Put off worries and troubles.

G. A good way to stay out of your head is to focus on the feeling in your body.
