The effect of pregnancy on asthma is unpredictable. In about one-third of women their asthma gets worse, especially during months 6 to 8.

The results of this 8-week study of progressive muscle relaxation (PMR) in 64 women in Germany might provide a management option.

When compared to placebo, pregnant women with asthma who practiced PMR experienced a significant reduction in systolic blood pressure and significant improvement in breathing (ie, forced expiratory volume, peak expiratory flow). There were also improvements in anxiety and overall health.

Here is more information from the American Lung Association to help get started using PMR.
