ABSTRACT
We have spent some time looking at sleep and activity, and we hope that by now you are already experimenting with changes in your daily activities and trying out strategies that may help improve the quality of your sleep. Now we would like to return to a topic that we introduced in the third chapter (thoughts and feelings). Hopefully after completing your thoughts and feelings diaries, you will have seen that a relationship exists between how you think and how you feel. We want to expand on this relationship by looking at behaviour and physiology, as well as thoughts and feelings. To help understand what is going on, we will use impact crosses (sometimes called Hot Cross Buns).
