Outline of Final Research Achievements

An observational study was conducted to investigate the impact of menstrual cycle phases on the cardiac autonomic nervous system controlling for the confounding effects of diet, physical activity, and sleep, which can be affected by the menstrual cycle. As a results, intake of protein and fat, as well as total sleep time and number of awakenings, were higher in the luteal phase than in the follicular phase. Although sympathetic nervous system (SNS) activity was higher in the luteal phase, the relationship was weakened after controlling for diet, physical activity, and sleep.
A randomized controlled trial was conducted to examine the effects of nocturnal energy intake on SNS activity during nighttime sleep. Our results suggest that SNS activity was significantly higher in the high nocturnal energy intake group than in low nocturnal energy intake group.
These studies indicated possibility of controlling SNS overactivity in premenstrual period by decreasing nocturnal energy intake.
