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.
Menstrual cramps are abdominal and pelvic pains experienced by a woman around the time of her menstrual period. Menstrual cramps usually start shortly before the menstrual period, peak within 24 hours after their onset, and subside after a day or two. Menstrual cramps can range from mild to severe. Mild menstrual cramps may be barely noticeable and short-lived, and they are sometimes felt only as a sense of mild pressure in the abdomen and pelvis. Severe menstrual cramps can be so painful that they interfere with a woman's regular activities for several days.
