Would that affect their learning? Many believe that sarting school later in the day will be helpful for younger kids. Lawrence Epstein, a doctor in Brighton, Massachusetts who is a medical director of sleep health centers and an instructor of medicine at Harvard Medical school who thinks that "adequate sleep is essential to feeling awake and alert, maintaining good health, and working at peak performance."
How early do schools start now? On the other side of things there are some challenges to starting school later. You might spend your time after school playing sports, doing homework, reading, or studying, but if schoo, started later that would cut time into those things. You would then have to balance those things in a shorter amount of time, and along with that kids would have to stay up later because they can sleep in later. While I do agree with this, I think that the positive outcomes would outweigh the negative ones.
