The joy of childbirth is often diluted in women due to postpartum depression. However, studies now show that even a low-intensity exercise, such as walking with a baby stroller can lower likelihood of depression in new mothers.

The study co-author Celia Alvarez-Bueno of the University of Castilla-La Mancha in Cuenca, Spain said, “The negative consequences of postpartum depression not only affect the mother but the child as well who can suffer poor emotional and cognitive development.”

Postpartum depression usually starts within four weeks of delivery and if they last for more than two weeks are considered to be a cause of worry.

The study team analyzed data among expectant mothers over a period of time and examined the severity of postpartum depression as well as including basic information about the length, frequency, type and intensity of the exercise.

The exercises used in the various studies included stretching and breathing, walking programs, aerobic activity, Pilates and yoga.

The study saw that women who didn’t exercise had a greater chance of slipping into depression.

The American College of Obstetrics and Gynecology recommended in 2009 that pregnant and postpartum women engage in 30 minutes of moderate physical activity most days of the week.
