3 Reasons Women Are More Likely to Have Insomnia

Women are twice as likely to have insomnia — the inability to fall asleep and stay asleep — as men. Much of this has to do with hormones, but some of it has to do with the ebbs and flows of a woman's life. Here are three common causes.

Hormones

There's a strong connection between hormones and sleep. In fact, when researchers study boys and girls and sleep, there are no differences until puberty starts. Then, at different times of the month, women and girls will sleep better than other times because of the fluctuations of their menstrual cycles. This sets the stage for poor sleep.

Other big hormonal milestones in a woman's life — pregnancy, the postpartum period and menopause — can also wreak havoc with regular schedules and sleep.

Mood disorders 

Women are more prone to mood disorders, such as anxiety and depression, leaving them more vulnerable to sleep problems. That's because many of the same chemicals in the brain that can be disrupted in mood disorders are also involved in regulating sleep.

The overlap of caregiver responsibilities and work 

Though roles are changing, women are more often the primary caregivers for children. Later on in life, women may end up being caregivers for their parents or their partner's parents. Some are doing double duty: caring for children and elderly parents at the same time.

In addition, women may be working outside of the home while caregiving. All of these activities decrease their sleep time.

Advice for insomniacs

Most people have insomnia at some time in their life for a few days or more. If the insomnia isn't interfering with your daily life or routines, don't worry.

On the other hand, if you have experienced insomnia three nights a week for three months or more, you have chronic insomnia and should seek the help of a health care provider, such as your physician or a sleep medicine specialist.
