Sleepy moms-to-be

It is estimated a third of Americans suffer from some type of insomnia.  Millions of pregnant women are among those complaining about lack of sleep.

Changing hormone levels, heartburn and the inability to get comfortable are some of the reasons moms-to-be can't get a good night's sleep.

The National Sleep Foundation has some tips for trying to minimize sleep loss during pregnancy:

1)  Go left.  Try to avoid lying on your back for long periods of time. Sleeping on your left side improves blood flow and the flow of nutrients to the baby. Bend your knees and place pillows between your legs, under your abdomen and behind your back.

2) What's that burning? Heartburn can be a real problem for pregnant women. The condition often surfaces while lying in bed. Eat smaller, more frequent meals throughout the day. Avoid spicy, acidic and fried food.

3) Drink up. Water that is! Fill up on fluids during the day, but cut down several hours before bedtime.

Finally, if it is okay with your doctor, exercise at least 30 minutes a day. A low impact workout is important for both mother and baby and may help promote a good night's sleep.
