7-hour sleep threshold linked to children's developmental delays in Chinese study.

A study from China indicates that pregnant women who sleep less than seven hours per night are at a higher risk of having children with developmental delays. Analyzing data from over 7,000 mother-child pairs, researchers found a link between short sleep duration and neurodevelopmental issues, particularly in boys. The findings suggest that inadequate sleep may affect maternal glucose metabolism, which could impact fetal development and health.
