At the beginning of pregnancy, pregnant women usually sleep well, as they are tired to take good care of the fetuses. However, with the enlargement of the volume of the fetus, it is difficult for women to sleep comfortably and conveniently. 

Except the enlargement of the volume of the fetus, many other factors can also increase the difficulty of having good rest for pregnant women, such as frequent micturition, increasing heart rate, short breath, constipation and mental pressure. Some women also have other symptoms, such as muscle cramp and backache. During the pregnant period, the burdens of the kidney and the bladder of women can be increased, which causes frequent micturition. With the enlargement of the uterine, the burden of diaphragm will be increased to cause the difficult breathing. At the same time, the demand of oxygen inside the body is increased, which forces women to accelerate the breathing. The enlargement of the uterine also needs more blood than before, so the workload of the heart has to be increased and the heart rate has to be quickened. When women are pregnant, the work efficiency of the digestive system is relatively low, and the foods have to stay in the gastric and intestinal tracts for a long time. Then constipation can be easily caused. Some pregnant women are attacked by dreaminess. Some women worry about the health situation of their fetuses and the mental pressure is worsened, which can also affect the quality of sleep.

Some skills are introduced to pregnant women to help them improve the sleep here. First, they should avoid drinking the beverages containing caffeine as far as possible, such as coffee and tea. If they really want to drink these beverages, they can drink them in the morning or after the afternoon nap. Second, they should not drink too much water or soup before going to bed. The moderate intake of supper can be helpful to the sleep. Third, the habit of regular sleeping should be formed. They can fall asleep and get up at the same time. Fourth, women should not take any strenuous exercises before they go to bed. Pregnant women can learn yoga to relax themselves. What’s more, women can read books, listen to music or watch television to accelerate the sleeping.

In short, pregnant women can make full use of the skills mentioned above to improve the quality of sleep for themselves according to their own situations.
