One-third of teens have experienced insomnia during their lives according to a recent study. The study also found that the risk of developing insomnia increased with puberty and that girls are 2.5 times more likely to experience insomnia after their first period.

According to The National Women's Health Information Center women are twice as likely to suffer from insomnia than men. Certain social factors may contribute to insomnia as well, such as being unemployed or divorced. In addition, women who are pregnant or peri-menopausal have trouble falling asleep and staying asleep, raising the likelihood of insomnia.
