Make relaxation your goal, not sleep. If you find 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 rejuvenate your body.
Relaxation CDs can help as they use a hypnotic voice to guide you through muscle relaxation and soothing music and sound effects to relax your brain.
If you wake up at night and can’t get back to sleep for more than 15 minutes try doing a quiet, non-stimulating activity, such as reading a book. Keep the lights dim so as not to cue your body clock that it’s time to wake up, a little book light is perfect. Don’t be tempted to read your emails!
Relaxation exercises, such as light yoga stretches, help to relax the muscles. Don’t exercise vigorously though, as it will have the opposite effect.
