Causes of Sleep Difficulties During Pregnancy
A number of problems can contribute to your sleeplessness during pregnancy. During early pregnancy, the same hormone that causes fatigue during the day can also disrupt your sleep cycle at night. You may have trouble finding a comfortable position for sleeping. You may find yourself waking up several times throughout the night to urinate.

In later pregnancy, a wide range of problems may disrupt your sleep. As the size of your abdomen increases, you may have trouble finding a comfortable position. Anxiety and stress can also contribute to sleeplessness, particularly as your due date approaches.

Other problems contributing to discomfort and insomnia include:

• Backache
• Congestion
• Gas
• Frequent urination
• Heartburn
• Hemorrhoids
• Leg cramps
• Nausea

Sleeping Difficulties: What You Can Do
Here are some tips to help you get enough rest: 

• Take a warm shower or bath. Take a shower or warm bath at bedtime. Remember that your sense of balance is off during your pregnancy. Be careful not to slip in a wet tub! Never take a bath if you think your water has broken.
• Reduce stress. Avoid placing yourself into stressful situations. Relaxation exercises, deep breathing or simply closing your eyes and imagining a peaceful scene may help. 
• Take naps. If you have a hard time getting restful sleep at night, take naps when possible during the day to avoid getting too fatigued.
• Avoid sleeping flat on your back. This puts the full weight of your uterus on your back and on the major vein that carries blood between your lower body and heart. This position can also increase your chances of getting backaches and can aggravate digestive problems, heartburn and hemorrhoids. Try to get used to sleeping on your side, particularly on your left side. This position can improve your circulation and help reduce swelling in your feet.
• Use pillows. Tuck one pillow between your legs. Use more pillows to support your back and abdomen. If you suffer from shortness of breath or heartburn, use pillows to elevate your upper body.
• Make your room comfortable. Don't watch television or read in bed. Use your bed only for sleeping. Make sure the room is at a comfortable temperature. Play some relaxing or natural sounds to help make you sleepy.
• Go to bed earlier. You may need to go to bed earlier than usual, especially if you find yourself waking up several times during the night. Go to bed when you feel tired. Don't push yourself to stay awake until your usual bedtime.
• Avoid getting up during the night. Drink adequate fluids earlier in the day, but avoid drinking anything for the two or three hours before bedtime. This will reduce the number of times you need to get up to urinate. If you are often troubled by heartburn, make sure to eat your last meal of the day several hours before lying down or going to sleep. To prevent nighttime leg cramps, gently stretch your leg muscles before bedtime.
• Exercise. Unless your health care provider has advised against it, try to exercise for at least 30 minutes per day. Even moderate exercise, like walking, can help you get a better night's sleep. Always be sure to find out from your health care provider what exercises are safe for you and how long you can maintain your exercise program.
• Do not take sleeping medications. Always talk to your health care provider before taking any medications.

When to Talk to Your Health Care Provider
Talk to your health care provider if your sleeplessness lasts a long time or continues to increase. If anxiety and stress are contributing to sleeplessness, your health care provider may be able to suggest support groups and other resources that may help.
