The solution for teenagers to get more sleep is not necessarily to start school later, but for teenagers to go to bed earlier. The sleep deprivation teens are experiencing is caused by staying up until midnight instead of going to sleep at a reasonable time on school nights. They spend too much time on electronic gadgets and not enough time on health, fitness and social interaction with other actual human beings.
The old saying, "Early to bed and early to rise makes a man healthy, wealthy and wise," still applies.
