Our thoughts and cognitions can affect sleep. The present dissertation aims to provide a better understanding of the mechanisms underlying how cognitions affect sleep. The empirical part of the dissertation includes three studies that examine the effect of positive and negative cognitions before and during sleep on sleep physiology. The theoretical part of the dissertation reviews mechanisms suggested by insomnia models and by the “Memories-of-Sleep” hypothesis, which assumes that mental concepts that are active during sleep affect sleep regulatory systems. The first study suggests that inducing positive cognitions during sleep by activating the mental concept of relaxation improves sleep depth. The second study showed that negative cognitions before sleep deteriorate sleep quality during early and during late sleep. The third study showed that positive cognitions before sleep enhance slow-waves but not memory consolidation processes. Thus, the empirical evidence of this dissertation suggests that positive and negative cognitions before as well as during sleep can affect sleep physiology. The findings are explained best by the theoretical framework of the “Memories-of-Sleep” hypothesis and provide a basis for future research and theory-driven interventions to improve sleep.
