Could SAD be affecting your sleep? Try this simple visualisation.
1. As the sun goes down, sit down and close your eyes. Imagine you are outside on the longest, sunniest day of the year. There is a light breeze, but you can feel the benevolent warmth of the sun on your face, and you love it.
2. Look up at the sky. You can see the bright, hot sun shining down on you, and you feel it more intensely now. Your body seems to have been basking in the sun's heat for hours. You are all aglow with its light and heat. You can feel it in every part of you and it seems to have seeped deep into you.
3. As you open your eyes you have a sense that you have been kissed by the sun. Even now, in the winter's dusk, you are flushed with sunlight.
