Pregnancy often has a significant impact on a woman’s quality of sleep, particularly during the first and third trimesters. Most often, this involves inadequate levels or quality of sleep (insomnia). However, some pregnant women may also develop other sleep disorders, such as sleep apnea or restless leg syndrome (sensations felt in the legs when at rest).

Changing hormone levels are among the top sources of sleeping disorders in pregnant women. In addition, many women lose sleep as a result of anxiety about impending parenthood, the health of the fetus or a changing relationship with their partner. Pregnant women often have to urinate more frequently, which contributes to increased awakenings throughout the night that may also disrupt sleep (nocturia).

Sleep concerns often initially appear during the first trimester. In many cases, women who experience sleep disruption during the first trimester have better sleep during the second trimester. During the third trimester, pregnant women commonly experience sleep difficulties, and in many cases these problems are even more intensified than in the first trimester.

Treating sleep problems during pregnancy is complicated by the fact that many medications have the potential to harm the fetus if taken by a pregnant woman. Women who experience sleep problems during pregnancy are encouraged to adhere to a consistent sleep schedule and to ensure that they are sleeping in an environment conducive to sleep. They also are encouraged to sleep on their left side to improve circulation during sleep.

Other tips for improving sleep during pregnancy include:

• Nap regularly during the daytime
  
  
• Avoid fluids before bed
  
  
• Avoid caffeinated beverages
  
  
• Use a pregnancy pillow
  
  
• Exercise regularly
