The head of the drum is traditionally made from goat skin, providing the djembe with piercing high-pitched tone and slap sounds (struck by the hand near the edge of the drum) owing to the thinness of goat skin (compared to antelope or calf-skin).
Why Am I So Tired While I Am Pregnant? No matter how much sleep you get, you will be tired for at least part of your pregnancy. This fatigue springs from the body changes and emotional stress caused by impending motherhood. Your body is working 24 hours a day, seven days a week, creating a new human being. That's enough work to make anyone tired.
Many, many women who are pregnant find themselves short of breath at some point. One reason is that the uterus is expanding and pushing up into the abdomen. This squeezes the lungs a bit, reducing the space they have for oxygen exchange. An even bigger cause for shortness of breath is progesterone, a hormone that increases during pregnancy. High progesterone levels cause pregnant women to breathe faster. The rise in progesterone begins early in pregnancy, and the shortness of breath it causes can come as a surprise. While shortness of breath can be worrisome, most of the time it is harmless and due to the normal changes of pregnancy.
