Psychophysiological Investigations of Post Lunch State in Male and Female Subjects

Abstract

Abstract Three complementary studies examined the effect of lunch within the context of diurnal variation recording of blood glucose, autonomic indices, body temperature, mood and performance efficiency in male and female subjects. The parasympathetic control of insulin is suggested as a mechanism which may underpin postprandial increases in deactivated mood. Sex differences in autonomic indices are related to possible sex differences in response to the laboratory environment and procedure.
