What can I do to ease my worries in pregnancy?

Stay active. Exercise is a great way to relieve stress. Your body releases endorphins during exercise, which can help you feel calm. If you exercise 30 - 60 minutes a day, your stress levels can improve. When stressed, take 5 slow, deep breaths with your eyes closed, then roll your shoulders forward 5 times, then back 5 times. This will slow your heart rate and release tension in your neck and shoulders.
Go for a walk. Pregnancy is a time of much hormonal change and you may experience emotions that you have never experienced before. If you are feeling worries coming on, go for a relaxing walk and enjoy the scenery. You and your baby deserve the relaxation.
