Our current school system could benefit from a more student friendly schedule. Many of the hours of operation for schools are determined by the bus and transportation companies and do little to consider the physical and mental well being of students. Some schools are beginning to address this by altering hours to suit students and are reaping the rewards for doing so. With such strong correlation between sleep and health (mental and physical), it would be wise to adopt a global practice of starting school day's off a little bit later. Thanks for taking this lesson. I wish you many many many great sleeps to come.
