My HormonologyDo you wake up in the middle of the night with your pulse racing and heart pounding after having a vivid nightmare? You’re not alone. A study out of the University of the West of England reveals that women are more likely to have intense and fearful nightmares than men, especially during Week 3 and Week 4 of their cycle.

One theory why: Your temperature rises slightly after ovulation, which may trigger changes in the brain that prompt the scary scenarios.

Want to have more pleasant dreams? Try putting a bowl of potpourri by your bedside (far from curious pets or kids) or spritzing on your favorite perfume or essential oil before bedtime. Research shows that breathing in a pleasant odor as you sleep makes you more likely to have positive dreams.
