When it comes to sleep, all men (and women) are not created equal

Researchers have found that, when it comes to sleep health, men and women are not created equal.

Studies show that sleep disorders do affect men and women differently. While men tend to suffer more from sleep apnea, women are more likely to report spending their nights tossing and turning.

Although researchers can't say for sure why women apparently have more trouble sleeping than men, they have noticed certain patterns. Particularly, women seem to have the most trouble falling asleep when hormone levels change - during pregnancy, early motherhood, menopause, and at certain times during the menstrual cycle.

Researchers know that the hormone progesterone causes sleepiness, and they also know that a woman's progesterone level rises during mid-month ovulation, and then drops dramatically at the onset of a menstrual period. This drop also is the time when many women report having sleep problems.
