Yes, Americans are sleep deprived. People are working crazy hours in offies unecessarily. The "early to bed and early to rise" mindset is outdated in the age of technology. People are trained to sleep during the school years, but once the hit the real world and realize that they can make their own way and not have to be on the 9 to 5 grind, it takes a while to adjust the sleep cycle.
With technology and screen access available anywhere and anytime, consumers are getting less sleep than ever. With growing pressures in the workplace, and the never slowing pace of the world, people are more overworked than ever. It has been proven that morning people are more productive and have higher work ethics that night owls, but both lack sufficient sleep.
Americans are sleep deprived. There have been various studies that have shown Americans do not get enough sleep. Adults between the ages of 26 and 64 should get seven to nine hours of sleep a night, according to the National Sleep Foundation. However, many people do not get this amount, resulting in poor work performance and increased traffic accidents.
Recent studies have shown that early morning risers are more productive. While night owls may be more intelligent, their schedules are not conducive to productivity. This could be more closely related to personality or discipline as opposed to actual intelligence quotient. Those that wake up at earlier hours and go to sleep earlier simply allow themselves more time to mentally prepare before they start their day. So, grades may be more closely correlated to schedule than total hours of sleep.
