PMDD) occurs in some women and not in others. Let me tell you what I think why PMS (and PMDD) occurs (part 3):
3. Lack of Exercise
The body is made to move. All the muscles in the body need to be conditioned on a daily basis. If you do not move, the muscles do not work properly and the body becomes sluggish and unable to function effectively. This is fact.
In order to ensure circulation is working properly, the body needs to be conditioned by exercise each day. The lymphatic system and circulatory system are very dependent on movement. If there is no movement, there is stagnation. If there is stagnation in the body, certain areas are not working properly and this means the hormones are not circulated correctly, the nutrients are not absorbed properly and stress levels increase.
A few preliminary studies have found that regular exercise can ease some of the pain and stress due to PMS. In one trial, researchers at the University of British Columbia in Vancouver had eight previously sedentary women work up to running 12 miles per week over six months. At the end of the study, the runners reported less breast tenderness, bloating, and moodiness before their periods.
At this stage, no studies have been done to determine if exercise helps with PMDD, but I assert that if exercise is part of a whole change in diet, lifestyle and stress reduction, it will dramatically reduce PMDD. I hope to be proved right (and vindicated) by some clinical studies in this area.
Exercise is an excellent way to relieve stress. Exercise releases endorphins (feel good hormones) which lighten you mood and reduce levels of stress hormones.
