FFP 053 | The Effect of Light on the Menstrual Cycle and Fertility | Sleeping in Darkness to Regulate Menstruation | Natural Family Planning | Joy DeFelice - a podcast by Lisa | Fertility Friday

Joy is a Registered Nurse, Bachelor of Science in Nursing, and a Public Health Nurse. She is the Director of the Natural Family Planning Program at Providence Sacred Heart Medical Centre in Spokane Washington. Joy and her Natural Family Planning students began studying the effects of night lighting on the menstrual cycle in 1976. Joy is the author of the book Effect of Light on the Menstrual Cycle and Fertility and her work has highlighted the significant impact of light on the menstrual cycle and fertility.

In today’s show, we talk about Joy’s research and how limiting our exposure to light at nighttime can improve menstrual cycle health and fertility. We also talk about the philosophy behind Natural Family Planning which gives a window into the differences and similarities between Natural Family Planning and the Fertility Awareness Method.
