Premenstrual syndrome (PMS) is a condition that affects many women 3 to 10 days before the beginning of their menstrual period.
The syndrome has a variety of symptoms, including anxiety, depression, sudden mood changes, crying easily, feeling angry or irritable, headaches, swelling, breast soreness, constipation, food cravings, and fatigue. Women affected by PMS may have any number of these symptoms at the same time, and the symptoms may be mild or severe. The cause of PMS is unknown.

Most doctors believe the symptoms result from hormone changes that take place during the menstrual cycle.

This music helps to stabilize the flow of energy in the electromagnetic field. When this occurs, the symptoms associated with PMS are less intense.
