BACKGROUND: Evidence exists for physical and psychological changes across the 28 days of menstrual cycle. Variation in the hormonal level have physical symptoms as oedema, breast tenderness, muscle pain, weight increase, vomiting and most notably water retention or body hydration in women. Significant changes in behavioral across the menstrual cycle such as mood swings, anxiety, depression, confusion, emotional liability, irritability, loss of concentration, lethargy, and aggression/hostility, have been associated with the menstrual cycle.

SUBJECTS /METHODS: Healthy females between the ages of 18-23 years of age were allowed to participate. Body hydration, Brain activity (EEG) and hormonal level during a normal menstrual cycle were determined using multi-frequency body impedance analysis (MFBIA), Data acquisition system (BIOPAC MP36) and ELISA procedure respectively.

RESULTS: Comparison of brain signal and hydration with both the sex hormone we found a correlation between the EEG wave forms, hydration status and the hormonal level. Progesterone seems to be in phase with alpha followed by the delta and theta while beta goes inversely. Delta and theta seems to be in phase with estrogen and out phase with alpha.

CONCLUSION: Result of present study shows that ovulatory cycle is associated body hydration and there is a correlation of body hydration with EEG pattern.
