Abstract Summary
Study of 275 eight-year-olds reveals a surprising bidirectional link: higher daytime physical activity correlates with shorter, more fragmented sleep that night, while better sleep predicts less activity the next day. Evening exercise did reduce time to fall asleep. These objective measurements challenge common beliefs that more active children sleep better.
Why Brain? 🧠
Study challenges common belief that more physical activity improves sleep in children. Using objective measurements, researchers found higher daytime activity actually linked to shorter, more fragmented sleep.
