This article from last year has a good overview of Why Sleeping May Be More Important Than Studying. Sleep isn’t just about resting your body and mind; it’s about consolidating and improving memory and learning as well. Helping your kids get a good night’s sleep is an important part of helping them to be more successful learners.
An important step is to not let children sleep with their smart phones or tablets. A recent study of Canadian students showed that students who had access to “electronic entertainment and communication devices” (tablets, computers, gaming devices, and smartphones) had shortened sleep cycles, among other poor outcomes. Many young people sleep with their phone within an arm’s reach, and wake to respond to messages and updates throughout the night. This disruption of sleep can not only shorten the time spent asleep, but prevent them from getting into the parts of the sleep cycle that are most important to learning.
