To the Editor:
As screen time becomes more interwoven into our everyday lives, it is crucial to understand it's possible impact on maternal health and fetal development. With the growing use of digital gadgets, pregnant women spend more time in front of screens than ever before. Although there is no study strongly in support of how these factors affect prenatal brain development is limited, some indirect mechanisms are worth investigating. These include maternal stress, sleep disruption, physical inactivity, and a decrease in maternal-fetal contact. These pathways highlight the significance of balancing screen use during pregnancy for optimal fetal brain development.1
Pregnant women who spend a lot of time on screens, particularly on social media, are more likely to experience stress, anxiety, and despair. According to research, high-stress chemicals, such as cortisol, can penetrate the placental barrier and disrupt fetal brain development, potentially resulting in long-term cognitive and emotional difficulties for the child. For example, Adamson et al2 discovered a substantial link between maternal anxiety during pregnancy and worse neurodevelopmental outcomes in children. Different types of screen-exposed activities may affect maternal health in distinct ways. Social media use has been linked to increased anxiety and depressive symptoms, potentially through mechanisms, such as social comparison and exposure to idealized portrayals of motherhood, which can lead to negative self-perception and elevated stress levels. Studies support this connection, demonstrating that higher social media usage correlated with increased feelings of isolation and depressive symptoms, which could have further implications for pregnant women.3,4 Similarly, excessive consumption of news, especially stressing or alarming information, may elevate stress, adding another layer or concern for pregnant women whose stress responses can affect fetal outcomes. Understanding these nuances in screen content can help guide future recommendations for screen time management in this population. Pregnant women should consider regulating their screen time to reduce these potential risks and promote better mental health.
Screen time, particularly before bedtime, has been shown to disrupt sleep patterns because of both blue light exposure and increased cognitive stimulation. Blue light emitted from screens interferes with the body's natural production of melatonin, a hormone essential for regulating sleep. This suppression of melatonin can delay sleep onset and disturb the overall sleep-wake cycle, leading to poorer sleep quality.5 During pregnancy, adequate sleep is especially crucial, as poor sleep quality has been associated with heightened risks of adverse outcomes, such as preterm birth and low birthweight, both of which are linked to compromised brain development in children.6 Research by Mindell and Jacobson7 underscores the essential role of sleep in supporting maternal health and optimal fetal development, suggesting that reducing screen exposure in the hours leading up to bedtime may help improve sleep quality and subsequently enhance pregnancy outcomes. Encouraging pregnant women to limit screen use before bed could be a practical strategy to support better sleep and reduce the risks associated with disrupted sleep during pregnancy.
Furthermore, excessive screen use frequently results in sedentary behavior and poor eating habits, both of which are detrimental during pregnancy. Physical activity is crucial for maintaining mother health and promoting fetal brain growth. Sedentary habits during pregnancy can cause issues, such as gestational diabetes mellitus and hypertension, both of which have a negative effect on fetal growth. In addition, a healthy diet rich in key nutrients is important for neurodevelopment. To ensure optimal health outcomes, the American College of Obstetricians and Gynecologists recommends that pregnant women engage in regular physical exercise and consume a balanced diet.8
Although the direct effect of screen time on fetal sensory development remains unclear, maternal well-being plays a crucial role in fetal brain development, and postnatal maternal-infant bonding has been shown to support emotional and cognitive development.9 Research highlights that maternal mental health, including reduced stress and anxiety, contributes to healthier developmental outcomes. Therefore, supporting pregnant women in managing stress and encouraging balanced screen time could be beneficial in promoting both maternal and fetal health.
Finally, although research on the direct influence of maternal exposure to screens on fetal brain development is still in its early stages, indirect routes reveal large potential effects. We can promote healthier pregnancies and improved developmental outcomes for children by emphasizing maternal stress reduction, sleep quality improvement, physical activity promotion, and maternal-fetal interactions. Future research should include longitudinal studies to examine the long-term effects of maternal screen time on infant development and randomized controlled trials to evaluate the efficacy of screen-time-reduction strategies. Policymakers should promote awareness campaigns regarding the possible consequences of excessive screen usage during pregnancy and provide efforts that urge expectant moms to adopt healthier lifestyles. Healthcare providers should be educated to counsel pregnant women about managing their time spent on screens.
