Biopsychology of Mood and Arousal

This book explores the interplay between physiological and psychological states in the light of increasing evidence that they exert subtle, long-term influences not only on mood, but also on perception, judgement, and cognitive processes in general; these, in turn, affect behaviour. Drawing on his own data from subjective assessments of mood and research by others, the author addresses questions such as what determines a person's mood and its changes; what is the relationship between mood and sugar snacking, smoking, coffee drinking, late-night worry, depression, and insomnia; what effect do exercise, time of day, nutrition, and sleep have on mood.
