Patient's question:
I heard that light helps in the development of fetal strength and can also establish good sleep patterns. From week 25 to 31, I practiced light, doing it twice a day in the morning and evening. Each time, I used a flashlight to shine on my abdomen by pressing it against the wall of my stomach. The light blinked on and off, meaning it flashed once every second. Each session lasted about 15 flashes, and while shining, I spoke to the baby, telling him about day and night. Today, I found out that the flashlight is a strong light flashlight, and I heard that strong light should not be used for exposure. I’m not sure if it will affect the baby’s vision. I hope an expert can clarify my doubts.Doctor's answer:
Currently, the widely practiced light-based prenatal education lacks strict standards in terms of light intensity, light duration, light source frequency, and the permeability of the light source to the's abdominal wall and placenta. The operation exhibits significant flexibility, and prolonged exposure to excessively strong light can adversely affect the visual and nervous system development of the fetus. Additionally, inappropriate light intensity and frequency may prevent the light from penetrating the uterus, failing to exert a suitable influence on the fetus and thus rendering the prenatal educational effects ineffective. Therefore, careful consideration must be given to the selection of the light source and the duration of light exposure.
