Helps Counteract Mood Swings
From the first menstrual cycle until menopause, women live with a shifting level of estrogen and progesterone that impacts their fertility patterns as well as also their brain chemistry and moods. When estrogen levels drop, such as before and during a womanâs period or leading up to menopause, women lose a natural source of the âfeel goodâ brain chemical called serotonin. This makes them more susceptible to moodiness, depression and anxiety attacks, such as the symptoms found in severe premenstrual syndrome or post-partum depression.
Exercise counters these hormonally-triggered mood swings by releasing endorphins, another mood regulator. Sometimes called the ârunnerâs high,â endorphins leave you feeling happy and relaxed after a workout.
âItâs our bodyâs way of substituting one natural chemical for one that is waning,â Dr. Horowitz says. âFor some women, this may reduce or eliminate the need for serotonin raising medications known as anti-depressants.â
Even after menopause, when estrogen levels have permanently diminished, exercise can improve mood. One study of 60 women experiencing postmenopausal anxiety and depression found that the group of participants who exercised showed an 18 to 22%improvement in symptoms, while those who did not exercise showed no improvement.
