Muscles in the Human Body. Muscles are how we move and live. All movement in the body is controlled by muscles. Some muscles work without us thinking, like our heart beating, while other muscles are controlled by our thoughts and allow us to do stuff and move around.
Cramping and Breast Tenderness. Cramping is one of the most common symptoms a woman experiences before, during or after her menstrual cycle. Caffeine contributes to cramps because of its diuretic nature--it increases urine production and promotes dehydration. In addition, coffee contains oils that may inflame your intestines and cause cramping.
In addition to medications, there are several steps that can alleviate menstrual cramps. Placing a heating pad on the abdomen, on a low setting, often eases the pain of cramps. To do this, lie down and place the pad over your lower abdomen until the menstrual cramps are alleviated.
